Most direct releases of chlorine to the environment are to air and to surface water. It can also escape from water and enter air under certain conditions. Some studies show that workers develop adverse effects from repeat inhalation exposure to chlorine, but others will not.Ĭhlorine dissolves when mixed with water. Human health effects associated with breathing or otherwise consuming small amounts of chlorine over long periods of time are not known. These effects are not likely to occur at levels of chlorine that are normally found in the environment. Chlorine irritates the skin, the eyes, and the respiratory system. Effects differ from coughing and chest pain, to water retention in the lungs. Effects also depend on the health of a person or condition of the environment when exposure occurs.īreathing small amounts of chlorine for short periods of time adversely affects the human respiratory system. It does not remain in the body, due to its reactivity.Įffects of chlorine on human health depend on how the amount of chlorine that is present, and the length and frequency of exposure. Chlorine is generally found only in industrial settings.Ĭhlorine enters the body breathed in with contaminated air or when consumed with contaminated food or water. People who use laundry bleach and swimming pool chemicals containing chlorine products are usually not exposed to chlorine itself. Water and wastewater treatment plants use chlorine to reduce water levels of microrganisms that can spread disease to humans (disinfection).Įxposure to chlorine can occur in the workplace or in the environment following releases to air, water, or land. Paper companies use chlorine to bleach paper. The largest users of chlorine are companies that make ethylene dichloride and other chlorinated solvents, polyvinyl chloride ( PVC) resins, chlorofluorocarbons, and propylene oxide. Health effects of chlorineĬhlorine is a highly reactive gas. The upper limit of tolerance varies according to the crop. Growth suffers if the amount of chloride in the soil fall below 2 ppm, but it rarely happens. Plants contain various amount of chlorine it is an essential microutrient for higher plants where is concentrates in the chloroplasts. The average in top soils is about 10 ppm. The amount of chloride in soils varies according to the distance from the sea. Chlorides make up much of the salt dissolved in the earth's oceans: about 1.9 % of the mass of seawater is chloride ions. In nature it is only found combined with other elements chiefly sodium in the form of common salt (NaCl), but also in carnallite, and sylvite.

It is used to kill bacteria and other microbes from drinking water supplies.Ĭhlorine is involved in beaching wood pulp for paper making, bleach is also used industrially to remove ink from recycle paper.Ĭhlorine often imparts many desired properties in an organic compound when it is substituted for hydrogen (synthetic rubber), so it is widely use in organic chemistry, in the production of chlorates, chloroform, carbon tetrachloride, and in the bromine extraction. in paper product production, antiseptic, dyestuffs, food, insecticides, paints, petroleum products, plastics, medicines, textiles, solvents, and many other consumer products. Chlorine gas is greenish-yellow and combines readily with nearly all other elements.Ĭhlorine is an important chemical in water purification, in disinfectants, in bleach and in mustard gas.Ĭhlorine is also used widely in the manufacture of many products and items directly or indirectly, i.e. It is extracted from chlorides through oxidation and electrolysis.

This element is a part of the halogen series forming salts. In its liquid and solid form it is a powerful oxidizing, bleaching, and disinfecting agent. Chlorine gas is two and one half times as heavy as air, has an intensely disagreeable suffocating odor, and is exceedingly poisonous. The name chlorine is derived from chloros, meaning green, referring to the color of the gas. The pure chemical element has the physical form of a diatomic green gas.

Chlorine was given its name in 1810 by Humphry Davy, who insisted that it was in fact an element.
