The use of chlorinated organic compounds in agriculture and industry has caused a number of environmental problems. A good illustration is provided by the case of 1,1,1 -trichloro-2,2-bis(p-chlorophenyl)ethane, better known as dichlorodiphenyl-trichloroethane, or DDT. 

Little is also known of the long term renal effects of chronic low dose exposure to pesticides. Chronic exposure to the now banned dichlorodiphenyl-trichloroethane (DDT), a lipophilic compound with prolonged body fat retention, has been associated with renal injury [105].

The commercial insecticide DDT is a mixture of several isomers, the major one (75—80%) being p,p -DDT (an abbreviation for p,p -dichlorodiphenyl-trichloroethane, which is more correctly named 1,1,1-trichloro-2,2-di(p-chlorophenyl)ethane Fig. 7.14). It was widely used after the Second World War, and appeared to offer the ultimate means of controlling a variety of insects that were major crop pests or disease vectors. It was beheved that excess DDT would be washed away, finally being diluted to negligible levels in the oceans. However, the harmful effects of the accumulation of the compound in vertebrates became apparent, and the use of DDT has virtually ceased in many countries, although it was still widely used in the UK as recently as the early 1980s (Newton et al. 1993) and continues to be used extensively in the tropics (Smith 1991). It is estimated that some 2.8 Mt had been manufactured worldwide by 1971 (Woodwell et al. 1971).

The rate at which a given chemical reaction proceeds can be expressed in several ways. To illustrate, consider the reaction of chlorobenzene and chloral to produce the insecticide DDT (dichlorodiphenyl-trichloroethane) in the presence of fuming sulfuric acid.

The role of chemistry became irreversibly intertwined with the environment in 1962 when the term ecosystem was introduced in Rachel Carson s Silent Spring. One of four works written by Carson, it targeted the now banned pesticide dichlorodiphenyl-trichloroethane (DDT), spawning a movement that resulted In the formation of the U.S. Environmental Protection Agency (EPA). 

These chemicals are considered in a pollution category because both deliberate and accidental release to the environment of several of these types of compounds, for example the industrial chemicals such as PCBs (polychlorinated biphenyls) and the chlorinated pesticides p,p DDT (dichlorodiphenyl-trichloroethane formal chemical name l,l -(2,2,2-trichloroethylidene)-bis (4-chlorobenzene)), have had unintended adverse environmental effects on diverse plants and animals and on people. Initially, chemicals such as PCBs and DDT were beneficial to human civilization PCBs as industrial chemicals allowing economical, safe delivery of electricity, and DDT as a pesticide eradicating vector pests of human health concern and agricultural crop pests. Only after these chemicals had entered widespread use did it become apparent that there were environmental problems, although in hindsight there was evidence of potential problems early in the history of their manufacture and use.
