Environmental problems Most of Tajikistan's environmental problems are associated with the agricultural policies imposed on the country during the Soviet period. By 1991 heavy use of mineral fertilizers and agricultural chemicals was a major cause of pollution in the republic. Among those chemicals were DDT, banned by international convention, and several defoliants and herbicides. In addition to the damage they have done to the air, land, and water, the chemicals have contaminated the cottonseeds whose oil is used widely for cooking. Cotton farmers and their families are at particular risk from the overuse of agricultural chemicals, both from direct physical contact in the field and from the use of the branches of cotton plants at home for fuel. All of these toxic sources are believed to contribute to a high incidence of maternal and child mortality and birth defects. In 1994 the infant mortality rate was 43.2 per 1,000 births, the second highest rate among former Soviet republics. The rate in 1990 had been 40.0 infant deaths per 1,000 births.
