[61] The chlorine produced is available in cylinders from sizes ranging from 450 g to 70 kg, as well as drums (865 kg), tank wagons (15 tonnes on roads; 27–90 tonnes by rail), and barges (600–1200 tonnes). Can’t find what you’re looking for? It may be dissolved in water to regenerate perchloric acid or in aqueous alkalis to regenerate perchlorates. The chlorate ions may themselves disproportionate to form chloride and perchlorate (4 ClO−3 ⇌ Cl− + 3 ClO−4) but this is still very slow even at 100 °C despite the very favourable equilibrium constant of 1020. However, it thermally decomposes explosively by breaking one of the central Cl–O bonds, producing the radicals ClO3 and ClO4 which immediately decompose to the elements through intermediate oxides. Gravity. Both materials were used in hot and cold water domestic plumbing, and stress corrosion cracking caused widespread failures in the US in the 1980s and 1990s. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst. Commercial processes, such as the Mitsui MT-Chlorine Process, have switched to chromium and ruthenium-based catalysts. …chlorine range of 0-4 ppm with an MDL of 0.03 ppm. [citation needed] Laboratory analysis of clothing and soil samples confirmed the use of chlorine gas against Kurdish Peshmerga Forces in a vehicle-borne improvised explosive device attack on 23 January 2015 at the Highway 47 Kiske Junction near Mosul. SO IT'S . [49] The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). P4(s) Hydrogen. This was not simply modern calcium chloride, but chlorine gas dissolved in lime-water (dilute calcium hydroxide) to form calcium hypochlorite (chlorinated lime). The drawback of using chlorine in swimming pools is that the chlorine reacts with the proteins in human hair and skin. It hydrolyses in water to give a mixture of chloric and perchloric acids: the analogous reaction with anhydrous hydrogen fluoride does not proceed to completion. What is the difference between a reagent blank and a sample blank? [46], Chlorine forms four oxoacids: hypochlorous acid (HOCl), chlorous acid (HOClO), chloric acid (HOClO2), and perchloric acid (HOClO3). Dioxins, produced when organic matter is burned in the presence of chlorine, and some insecticides, such as DDT, are persistent organic pollutants which pose dangers when they are released into the environment. Potassium atoms have 19 electrons and the shell structure is 2.8.8.1. [48], Like the other carbon–halogen bonds, the C–Cl bond is a common functional group that forms part of core organic chemistry. After the chlorine demand is met, the remaining chlorine is called total chlorine. Other materials present in the water may generate disinfection by-products that are associated with negative effects on human health. H2(g) Neon. W - the number of ways in which the macroscopic thermodynamic state of the system can be realized through microscopic states. Chlorine Standard Solution, 25-30 mg/L as Cl₂, pk/20 - 2 mL PourRite Ampules (NIST) Order Status Contact Us Login. [70] These "putrid miasmas" were thought by many to cause the spread of "contagion" and "infection" – both words used before the germ theory of infection. [110][111] Chlorine-iron fires are a risk in chemical process plants, where much of the pipework that carries chlorine gas is made of steel. Saturated sodium (or potassium) chloride solution is passed through the anode compartment, leaving at a lower concentration. Any pending input will be lost. [62] The most significant of organic compounds in terms of production volume are 1,2-dichloroethane and vinyl chloride, intermediates in the production of PVC. The last is very convenient in the laboratory because all side products are gaseous and do not have to be distilled out. The process proceeds according to the following chemical equation:[58]. Contrary to popular belief, the distinctive 'chlorine aroma' associated with swimming pools is not the result of elemental chlorine itself, but of chloramine, a chemical compound produced by the reaction of free dissolved chlorine with amines in organic substances. Photolysis of individual ClO2 molecules result in the radicals ClO and ClOO, while at room temperature mostly chlorine, oxygen, and some ClO3 and Cl2O6 are produced. This temperature/pressure combo is often called "room conditions." Our company was founded on integrity. Kr(g) Oxygen. Eleven elements are gas in their standard state. Its most important salt is sodium chlorate, mostly used to make chlorine dioxide to bleach paper pulp. However, the instrument does accept a user-prepared calibration curve, if the user chooses to do so. STUDY. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. How to Handle Chlorine Gas Safely Exposure to chlorine is irritating to the eyes, nose, throat, and mucous membranes. PLAY. [103] The toxicity of chlorine comes from its oxidizing power. The same chemicals were found to be useful in the routine disinfection and deodorization of latrines, sewers, markets, abattoirs, anatomical theatres, and morgues. [47] Dichlorine hexoxide is a dark-red liquid that freezes to form a solid which turns yellow at −180 °C: it is usually made by reaction of chlorine dioxide with oxygen. F2(g) Sulfur. [49], Alkanes and aryl alkanes may be chlorinated under free-radical conditions, with UV light. So, you are going to specify DECHLORINATION. [102] Breathing lower concentrations can aggravate the respiratory system and exposure to the gas can irritate the eyes. Spell. The chemical symbol (not formula) of mercury is Hg. A chemical formula of … Chlorous acid (HOClO) is even more unstable and cannot be isolated or concentrated without decomposition: it is known from the decomposition of aqueous chlorine dioxide. Learn More. Learn more about Formyl chloride chemical formula at Mol-Instincts. Answer to: Write a complete chemical formula including physical state symbol, for each element listed below in its standard state. Standard States of Elements. 3p5 and the term symbol of chlorine is 2P3/2. Chlorine dioxide is a chemical compound with the formula ClO 2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C. As said above, carbon is a solid in its standard state, or more accurately, it is in graphite form. Despite attempts to rationalise it as the dimer of ClO3, it reacts more as though it were chloryl perchlorate, [ClO2]+[ClO4]−, which has been confirmed to be the correct structure of the solid. There was an error with your submission. Please try again. The standard molar enthalpy of formation ΔH o f is the enthalpy change when 1 mole of a pure substance, or a 1 M solute concentration in a solution, is formed from its elements in their most stable states under standard state conditions. However, in the presence of light, these solutions rapidly photodecompose to form a mixture of chloric and hydrochloric acids. When chlorine is added to drinking water, it proceeds through a series of reactions described below.When chlorine is added to water, some of the chlorine reacts first with inorganic and organic materials and metals in the water and is not available for disinfection (this is called the chlorine demand of the water). However, due to the expense and reactivity of chlorine, organochlorine compounds are more commonly produced by using hydrogen chloride, or with chlorinating agents such as phosphorus pentachloride (PCl5) or thionyl chloride (SOCl2). KL + hydrogen chloride. [77] By 1918, the US Department of Treasury called for all drinking water to be disinfected with chlorine. The Iraqi authorities tightened security for elemental chlorine, which is essential for providing safe drinking water to the population. Labarraque's chlorinated lime and soda solutions have been advocated since 1828 to prevent infection (called "contagious infection", presumed to be transmitted by "miasmas"), and to treat putrefaction of existing wounds, including septic wounds. [46] Chlorine perchlorate may also be considered a chlorine derivative of perchloric acid (HOClO3), similar to the thermally unstable chlorine derivatives of other oxoacids: examples include chlorine nitrate (ClONO2, vigorously reactive and explosive), and chlorine fluorosulfate (ClOSO2F, more stable but still moisture-sensitive and highly reactive). Chlorine adds to the multiple bonds on alkenes and alkynes as well, giving di- or tetra-chloro compounds. [55], Some types of organochlorides, though not all, have significant toxicity to plants or animals, including humans. Phosphorus (ms) P4 -white. Example: the chlorine standard solution value is 63.1 mg/L. Several catastrophic collapses of swimming pool ceilings have occurred from chlorine-induced stress corrosion cracking of stainless steel suspension rods. [64] The remaining 19% of chlorine produced is used for bleaches and disinfection products. One mL was pipetted into a 200-mL flask and diluted to the mark. Perchlorates are made by electrolytically oxidising sodium chlorate, and perchloric acid is made by reacting anhydrous sodium perchlorate or barium perchlorate with concentrated hydrochloric acid, filtering away the chloride precipitated and distilling the filtrate to concentrate it. [76], The first continuous application of chlorination to drinking U.S. water was installed in Jersey City, New Jersey in 1908. Cart 0 / Quote 0. You have been directed to this answer based on an ID match. This method also produces very pure sodium (or potassium) hydroxide but has the disadvantage of requiring very pure brine at high concentrations.[60]. [86], Chlorine gas was also used during the Iraq War in Anbar Province in 2007, with insurgents packing truck bombs with mortar shells and chlorine tanks. [89], The Syrian government has allegedly used chlorine as a chemical weapon[90] delivered from barrel bombs and rockets. It exists as a yellow-green gas at standard temperature and pressure, and its density is 3.2 grams per liter. The major inorganic compounds include HCl, Cl2O, HOCl, NaClO3, chlorinated isocyanurates, AlCl3, SiCl4, SnCl4, PCl3, PCl5, POCl3, AsCl3, SbCl3, SbCl5, BiCl3, S2Cl2, SCl2, SOCI2, ClF3, ICl, ICl3, TiCl3, TiCl4, MoCl5, FeCl3, ZnCl2, and so on. As can be seen from the redox potentials given in the adjacent table, chlorine is much more stable towards disproportionation in acidic solutions than in alkaline solutions:[35], The hypochlorite ions also disproportionate further to produce chloride and chlorate (3 ClO− ⇌ 2 Cl− + ClO−3) but this reaction is quite slow at temperatures below 70 °C in spite of the very favourable equilibrium constant of 1027. In some bombings, over a hundred civilians were hospitalized due to breathing difficulties. Chlorination modifies the physical properties of hydrocarbons in several ways: chlorocarbons are typically denser than water due to the higher atomic weight of chlorine versus hydrogen, and aliphatic organochlorides are alkylating agents because chloride is a leaving group. The DR300 for chlorine (Product # LPV445.97.00110) and the Pocket Colorimeter™ II, Chlorine (Free and Total) (Product # 5870000) is factory calibrated and does not need to be user calibrated. The concentration of the diluted standard is 63.1 x 0.005 = 0.32 mg/L chlorine. NIST / TRC Web Thermo Tables, professional edition (thermophysical and thermochemical data) [69] In his 1828 work, Labarraque recommended that doctors breathe chlorine, wash their hands in chlorinated lime, and even sprinkle chlorinated lime about the patients' beds in cases of "contagious infection". Bromine (l) Br. The Colorimeter is also EPA Compliant, (tablet version), using proper wavelength and DPD test method to meet EPA design specifications for NPDWR and NPDES chlorine monitoring programs (EPA 330.5 and Standard Method 4500). Chlorine reacts with water in the mucosa of the lungs to form hydrochloric acid, destructive to living tissue and potentially lethal. Entropy is a dimensionless quantity. [95] Hyperchloremia (having too much chloride) usually does not produce symptoms. Gravity. What can be done if a Pocket Colorimeter II reads much higher on chlorine SpecChecks than the certificate states. In this class, the standard state is 1 … [50][51] Chlorinated organic compounds are found in nearly every class of biomolecules including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. It is the twenty-first most abundant element in Earth's crust and makes up 126 parts per million of it, through the large deposits of chloride minerals, especially sodium chloride, that have been evaporated from water bodies. [62], Sodium chloride is the most common chlorine compound, and is the main source of chlorine for the enormous demand associated with today's chemicals industry. : Disinfectants Create Toxic By-products", "Why You Should Never Mix Different Drain Cleaners", "Bleach Mixing Dangers : Washington State Dept. of Health", Helmont, Johannes (Joan) Baptista Van, Encyclopedia.Com, Agency for Toxic Substances and Disease Registry, Chlorine Production Using Mercury, Environmental Considerations and Alternatives, National Institute for Occupational Safety and Health – Chlorine Page, U.S. Army Edgewood Chemical Biological Center, U.S. Army Medical Research Institute of Chemical Defense, Program Executive Office, Assembled Chemical Weapons Alternatives, Johnston Atoll Chemical Agent Disposal System, Unethical human experimentation in the United States, Octamethylene-bis(5-dimethylcarbamoxyisoquinolinium bromide), 2-Ethoxycarbonyl-1-methylvinyl cyclohexyl methylphosphonate, https://en.wikipedia.org/w/index.php?title=Chlorine&oldid=992165045, World Health Organization essential medicines, Articles with dead external links from December 2017, Articles with permanently dead external links, CS1 maint: BOT: original-url status unknown, Wikipedia indefinitely semi-protected pages, Wikipedia indefinitely move-protected pages, Short description is different from Wikidata, Articles containing Ancient Greek (to 1453)-language text, Articles with unsourced statements from October 2020, Wikipedia articles incorporating a citation from the 1911 Encyclopaedia Britannica with Wikisource reference, Articles with unsourced statements from April 2020, Creative Commons Attribution-ShareAlike License, Wisniak, Jaime (2009) "Carl Wilhelm Scheele,", This page was last edited on 3 December 2020, at 21:07. [56] Due to the ready homolytic fission of the C–Cl bond to create chlorine radicals in the upper atmosphere, chlorofluorocarbons have been phased out due to the harm they do to the ozone layer. [63] About 15,000 chlorine compounds are used commercially. [22] Along with chlorine, the method yields hydrogen gas and sodium hydroxide, which is the most valuable product. Diluted concentration = chlorine ampule concentration x multiplier. Neither has a change that you would have to account for in the formula, as they both have +1 and -1 charge. Although it is a weak ligand, weaker than water, a few compounds involving coordinated ClO−4 are known. These compounds are stable while solid and may be used in powdered, granular, or tablet form. Due to the difference of electronegativity between chlorine (3.16) and carbon (2.55), the carbon in a C–Cl bond is electron-deficient and thus electrophilic. Cl2O3 is also produced when photolysing the solid at −78 °C: it is a dark brown solid that explodes below 0 °C. Formyl chloride contains total 4 atom(s); 1 Hydrogen atom(s), 1 Carbon atom(s), 1 Oxygen atom(s) and 1 Chlorine atom(s). Its melting point is -150.7 degrees Fahrenheit, and its boiling point is -29.27 degrees Fahrenheit. When added in small amounts to pool water or industrial water systems, the chlorine atoms hydrolyze from the rest of the molecule, forming hypochlorous acid (HOCl), which acts as a general biocide, killing germs, microorganisms, algae, and so on. 3s2. Its molar mass is 70.906 grams per mole. [54] A majority of the chloromethane in the environment is produced naturally by biological decomposition, forest fires, and volcanoes. STUDY. [72]:296, Perhaps the most famous application of Labarraque's chlorine and chemical base solutions was in 1847, when Ignaz Semmelweis used chlorine-water (chlorine dissolved in pure water, which was cheaper than chlorinated lime solutions) to disinfect the hands of Austrian doctors, which Semmelweis noticed still carried the stench of decomposition from the dissection rooms to the patient examination rooms. Diaphragm methods produce dilute and slightly impure alkali, but they are not burdened with the problem of mercury disposal and they are more energy efficient. The Chlorine nitrate molecule contains a total of 5 atom (s). In the Deacon process, hydrogen chloride recovered from the production of organochlorine compounds is recovered as chlorine. so it KL + HCL = KL + 2HCL [72][73][74] One reference makes it clear that chloride of lime was used to disinfect the offal and filth in the streets surrounding the Broad Street pump—a common practice in mid-nineteenth century England. It was pioneered by a German scientist later to be a Nobel laureate, Fritz Haber of the Kaiser Wilhelm Institute in Berlin, in collaboration with the German chemical conglomerate IG Farben, which developed methods for discharging chlorine gas against an entrenched enemy. Chlorine is a chemical element with the symbol Cl and atomic number 17. [87][88], On 24 October 2014, it was reported that the Islamic State of Iraq and the Levant had used chlorine gas in the town of Duluiyah, Iraq. The electrolysis of chloride solutions all proceed according to the following equations: In diaphragm cell electrolysis, an asbestos (or polymer-fiber) diaphragm separates a cathode and an anode, preventing the chlorine forming at the anode from re-mixing with the sodium hydroxide and the hydrogen formed at the cathode. Mercury (l) Hg. HACH US Chemistries CLAROS 800-227-4224. Other OSHA standards that generally apply to hazardous substances include the Hazard Communication standard and the Respiratory Protection standard . It also tasted metallic and stung the back of the throat and chest. Chloride of lime was used for destroying odors and "putrid matter". Chlorine is detectable with measuring devices in concentrations as low as 0.2 parts per million (ppm), and by smell at 3 ppm. Thus, it would be C(graphite)(s) Oxygen is a diatomic gaseous molecule at standard state and is thus denoted as O2(g) <-- subscript 2 Chlorine gas is a strong oxidizer, which may react with flammable materials.[100][101]. Two elements are liquid in their standard state: mercury and bromine. Match. One source claims chloride of lime was used by Dr. John Snow to disinfect water from the cholera-contaminated well that was feeding the Broad Street pump in 1854 London,[71] though three other reputable sources that describe that famous cholera epidemic do not mention the incident. Express Order. [80], It is often impractical to store and use poisonous chlorine gas for water treatment, so alternative methods of adding chlorine are used. Learn. In fact, the U.S. Environmental Protection Agency requires treated tap water to contain a detectable level of chlorine to help protect against germs all the way to consumers’ taps. At high ... and, in Washington, the state Department of Labor and Industries regulate chlorine quantities of 1,500 pounds or more. Login. What chlorine standards are available for checking the accuracy of chlorine measurements? Key Concepts: Terms in this set (25) Iron. cl and h2o. It is two and a half times heavier than air. CS1 maint: BOT: original-url status unknown (. The ground state electronic configuration of neutral potassium is [Ar].4s 1 and the term symbol of potassium is 2 S 1/2.. Potassium: description Your user agent does not support the HTML5 Audio element. Cl2(g) Krypton. Sulfur (ms) S8 -rhombic crystal. Write. The rates of reaction for the chlorine oxyanions increases as the oxidation state of chlorine decreases. 9 Hypochlorination – Sodium Hypochlorite", The Ghost Map: The Story of London's Most Terrifying Epidemic and How It Changed Science, Cities, and the Modern World, “Drinking Water: A Half Century of Progress.”, "Comparison of chlorine, bromine, iodine as disinfectants for swimming pool water", "Syria Used Chlorine Bombs Systematically in Aleppo, Report Says", "Syrian forces 'drop chlorine' on Aleppo", "Ignoring UN, Russia and Assad continue Syrian chemical weapons and bombing attacks labeled war crimes", "The pathogenesis of hypochloremia in respiratory acidosis", "What's in your Water? Coughing and vomiting may occur at 30 ppm and lung damage at 60 ppm. Test. It is a shock-sensitive, colourless oily liquid. Write. Infobox references Copper(II) chlorate is a chemical compound of the transition metal copper and the chlorate anion with basic formula Cu(ClO 3 ) 2 . The attacks killed two people from the explosives and sickened more than 350. B(s) Tin. [75], Much later, during World War I in 1916, a standardized and diluted modification of Labarraque's solution containing hypochlorite (0.5%) and boric acid as an acidic stabilizer was developed by Henry Drysdale Dakin (who gave full credit to Labarraque's prior work in this area). It is sometimes associated with hypoventilation. If our standards aren't measuring up to yours, we want to know. There are 1 Nitrogen atom (s), 3 Oxygen atom (s) and 1 Chlorine atom (s). Joseph Cotruvo, Victor Kimm, Arden Calvert. nH2O (n ≈ 6–10) separate out at low temperatures. Chloric acid (HOClO2) is a strong acid that is quite stable in cold water up to 30% concentration, but on warming gives chlorine and chlorine dioxide. Chloride and chlorate may comproportionate to form chlorine as follows:[48], Perchlorates and perchloric acid (HOClO3) are the most stable oxo-compounds of chlorine, in keeping with the fact that chlorine compounds are most stable when the chlorine atom is in its lowest (−1) or highest (+7) possible oxidation states. [94] It can be associated with chronic respiratory acidosis. [79] Increasingly, monochloramine itself is being directly added to drinking water for purposes of disinfection, a process known as chloramination. The National Institute for Occupational Safety and Health has designated a recommended exposure limit of 0.5 ppm over 15 minutes. Fluorine is found in nature only in the form of its chemical compounds, except for trace amounts of the free element in fluorspar that has been subjected to radiation from radium.Not a rare element, it makes up about 0.065 percent of Earth’s crust. Overly low or high concentrations of chloride in the blood are examples of electrolyte disturbances. As a disinfectant in water, chlorine is more than three times as effective against Escherichia coli as bromine, and more than six times as effective as iodine. However, the extent of chlorination is difficult to control: the reaction is not regioselective and often results in a mixture of various isomers with different degrees of chlorination, though this may be permissible if the products are easily separated. Standard Enthalpies of Formation. [110][111], This article is about the chemical element. A modified version of this solution continues to be employed in wound irrigation in modern times, where it remains effective against bacteria that are resistant to multiple antibiotics (see Century Pharmaceuticals). However, sodium chlorite is a stable salt and is useful for bleaching and stripping textiles, as an oxidising agent, and as a source of chlorine dioxide. In 1828, the contagion of infections was well known, even though the agency of the microbe was not discovered until more than half a century later. Oxygen (g) O2. [65][66] The prize was won by Antoine-Germain Labarraque, a 44-year-old French chemist and pharmacist who had discovered that Berthollet's chlorinated bleaching solutions ("Eau de Javel") not only destroyed the smell of putrefaction of animal tissue decomposition, but also actually retarded the decomposition. Fluorine (g) F2. [109], The element iron can combine with chlorine at high temperatures in a strong exothermic reaction, creating a chlorine-iron fire. We are now changing the way we deliver our quality standards. [83][84] As described by the soldiers, it had the distinctive smell of a mixture of pepper and pineapple. [46], Chlorine is too reactive to occur as the free element in nature but is very abundant in the form of its chloride salts. [96], Chlorine is a toxic gas that attacks the respiratory system, eyes, and skin. About 1000 ppm can be fatal after a few deep breaths of the gas. It is the least reactive of the chlorine oxides, being the only one to not set organic materials on fire at room temperature. But our control…and the control of every standard manufacturer…ends shortly after a standard is calibrated and packaged. Created by. [102], In the home, accidents occur when hypochlorite bleach solutions come into contact with certain acidic drain-cleaners to produce chlorine gas. PLAY. S8(s) Phosphorus. [67] They were successful in hospitals, lazarets, prisons, infirmaries (both on land and at sea), magnaneries, stables, cattle-sheds, etc. ug/L (PPB) tomg/L (PPM) • To convert micrograms per liter to milligrams per liter, divide by 1000. [81][82], Chlorine gas, also known as bertholite, was first used as a weapon in World War I by Germany on April 22, 1915 in the Second Battle of Ypres. Courtneynp09. For requirements in Washington, call (360) 902-5478. The first row of the table has been completed for you element formula Fe(s) iron neon neodymium chlorine During the Paris cholera outbreak of 1832, large quantities of so-called chloride of lime were used to disinfect the capital. Your browser will not offer you the best experience in this format. Hypochloremia (having too little chloride) rarely occurs in the absence of other abnormalities. O2(g) Boron. [57], Small batches of chlorine gas are prepared in the laboratory by combining hydrochloric acid and manganese dioxide, but the need rarely arises due to its ready availability. About 15000 chlorine-containing compounds are commercially traded, including such diverse compounds as chlorinated methane, ethanes, vinyl chloride, polyvinyl chloride (PVC), aluminium trichloride for catalysis, the chlorides of magnesium, titanium, zirconium, and hafnium which are the precursors for producing the pure form of those elements. It becomes a liquid at −34 °C (−29 °F). chlorinated water. Even small water supplies are now routinely chlorinated. [53] In addition, a variety of simple chlorinated hydrocarbons including dichloromethane, chloroform, and carbon tetrachloride have been isolated from marine algae. This was done in "gut factories" (boyauderies), and it was an odiferous and unhealthy process. [93] The main dietary source is table salt, or sodium chloride. In most private swimming pools, chlorine itself is not used, but rather sodium hypochlorite, formed from chlorine and sodium hydroxide, or solid tablets of chlorinated isocyanurates. hydrogen chloride because chlorine goes with oxygen from water to form a chloride solution and hydrogen is on its own. In or about 1820, the Société d'encouragement pour l'industrie nationale offered a prize for the discovery of a method, chemical or mechanical, for separating the peritoneal membrane of animal intestines without putrefaction. When used at specified levels for water disinfection, the reaction of chlorine with water is not a major concern for human health.
