Chlorine long-term health effects

Whole NR body NR Review of medical records of soldiers gassed with chlorine. Acute effects included death, dyspnea, pulmonary edema, bronchitis, pneumonia, asthma. Long-term effects (4 yr after exposure) included irritable heart" (condition not described). There appeared to be no correlation between acute pulmonary effects and health status 4 yr later. Meakins and Priestly 1919... [Pg.125]

Additional studies on the toxicity of chlorine in experimental animals are needed to better define the health effects of exposure at concentrations of 0.5—4 ppm, 24 h/d for up to 10 d. These studies should include evaluation of short-term effects, on pulmonary function and on long-term effects such as inflammation of the respiratory tract and pulmonary fibrosis. Studies are also needed on the interactive effects of chlorine with other gases found in disabled submarines. [Pg.146]

Chlorinated organic compounds (COCs) refer to the substitution of one or more hydrogen in aliphatic and aromatic hydrocarbons and their derivatives by chlorine. COCs are widely used in the fields of chemistry, medicine, electronics, pesticides, etc. Many COCs are endocrine disturbance substances, show carcinogenic effects, and have been listed as priority pollutants by the US Environmental Protection Agency (USEPA). When released into the environment, COCs are transported in both air and water. However, COCs are chemically stable and difficult to destroy, and they are eventually deposited in soils and sediments due to their hydrophobic-ity. Soils and sediments contaminated with COCs are long-term sources of pollutants and pose great threats to human health and ecosystems. Therefore, remediation of these contaminated soils and sediments is of great importance. [Pg.219]

Many landfills contain VOCs (volatile organic chemicals). This group of chemicals includes benzene and toluene (both carcinogens), chlorinated hydrocarbons, such as carbon tetrachloride, and trichloroethylene, which previously was used as a dry-cleaning solvent. Even though these compounds are not very soluble in water, they do accumulate at the parts-per-million level. Their long-term effect on human health is unknown at this time. [Pg.308]
