...insect depredations. During World War II, German and Allied laboratories produced complex and lethal chemical compounds, including DDT and lindane. Since then new generations of pesticides such as carbamates (Bux Ten, Furadan and Mobam) have proved to be efficient at curbing insects and microscopic pests without producing the strong toxic effects of DDT on the environment. At the same time, however, these new silent killers still pose a potential threat to other forms of life, including human...
Last week's disaster in Bhopal focused world attention on two highly volatile and toxic gases, methyl isocyanate and phosgene. They, along with many other chemicals, are used in the production of pesticides. Methyl isocyanate (MIC) helps produce Union Carbide's Temik, a product marketed under Robert Gordon Haines, the company's manager for new pesticides. It is one of a group of chemicals called isocyanates that are used to make polyurethane, which, in turn, is used to make paint and varnish. The MIC compound also has been made in the U.S. at Union Carbide...
Phosgene, synthesized early in the 19th century and also known as carbonyl chloride, is a colorless, highly toxic gas. It is used to make chemicals like MIC, as well as dyes and resins. Phosgene first gained infamy during World War I, when the Germans used it alone or with chlorine in deadly gas attacks. Later, the gas came to be widely used in the manufacture of pesticides...
...links are difficult to prove scientifically, many of the chemicals in hazardous wastes are believed to cause cancer and birth defects. More than 66,000 different compounds are used in industry, and less than 2% have been tested for possible side effects. Over the years the dangers of slow, toxic seepage may far outweigh the confined outburst of a primary disaster...
...comprising 225 different chemicals, was produced in the U.S. last year, and an additional 79 million lbs. was imported. MIC is stored or used at plants in New York, West Virginia, Texas, Alabama and Georgia. Those insecticides not dependent on the compound, like malathion, are also construct ed of toxic molecules. Dow Chemical Co., one of the nation's largest producers of agricultural and industrial chemicals, is reconsidering its safety and spillage codes. American Cyanamid, a major chemical manufacturer, is busy comparing its emergency procedures with those of Union Carbide...
