Exposure to a high amount of DDT leads to vomiting, convulsions, and vomiting. It has ant androgenic effects; also, it causes infertility, low birth weight, pancreatic cancer, lung cancer, leukemia, non-Hodigkin's lymphoma and breast cancer.
In a study workers were exposed to DDT, they had skin and eye irritation, neurological abnormality (Ortelee 1958, Laws et At 1967, WHO 1973). Increased the metabolism rate for steroids and drugs due to hepatic microsomal enzyme induction, also; the lymphocyte's chromatid aberrations were increased. Those workers had 1.0 ppm mean residues in blood that are equivalent to 18 mg daily intake of DDT.
Using of DDT was banned in the United States in 1972, except if there is cases of public health emergency.
