Chemical contamination refers to the contamination of the environment with chemical substances, there are many chemical contaminants, and some of them are volatile found in our environment.
Benzene is one of them, it evaporates rapidly, it smells sweet, flammable, colorless liquid, it presents in gasoline, crude oil, and cigarette smoke.
Benzene is one of the chemical contaminant which used in manufacturing many products like plastics, synthetic fibers and resin.
Also, it is used to solve waxes, oils, resins, and rubber.
We can get exposure to benzene from tobacco smoke, motor vehicle exhaust, gas station, glues, paints, and detergents.
Benzene has many effects on human body after long time exposure, it causes acute myelogenous leukemia which …show more content…
Also it is used for malaria and typhus during the World War II to 1972. It accumulates in the adipose tissue; it is half life around ten years.
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.
Dioxins are chemical compounds, and also considered as persistent environmental pollutants, dioxin's chemical name is (2, 3, 7, 8-tetrachlorodibenzo para dioxin, TCDD)
They are highly toxic compound, accumulate in the adipose tissue, and have long half-life, there is 419 compounds of dioxins, just 30 of them are highly
