Chemical pollutants: benzene

Current indoor decoration with toluene and xylene substitute pure benzene for glue, paint, coatings and waterproofing materials of solvents or thinners.

Because of a volatile, flammable, explosive vapor. People in a short time inhalation of high concentration of toluene, xylene, may appear in the central nervous system effects, light anesthesia were dizziness, headache, nausea, chest tightness, weak, fogged, serious-induced coma resulting in respiratory and circulatory failure and death. If the long-term exposure to certain concentration of toluene, xylene, causing chronic poisoning, headaches, insomnia, mental depression, memory loss, neurasthenia-like syndrome. Benzene compounds have been identified as the World Health Organization strongly carcinogens.

Home and office buildings in Bon primarily from architectural decoration with a wide range of chemical raw materials such as coatings, fillers and various organic solvents, etc., through volatilization to Interior decorated, benzene, mainly in the following kinds of decorative materials in high: paint, various kinds of paint coatings additives and diluent, adhesives, waterproofing materials, some low and phony coatings.

Chronic benzene poisoning is benzene on skin, eyes and respiratory tract has a stimulating effect.

Often exposed to benzene, the skin may become dry skim, desquamation, allergic eczema appears.

Inhaling benzene can cause aplastic anemia.

The early gum and nasal mucosa has the similar to scurvy, and hemorrhagic disease-like symptoms of neurasthenia, manifested as dizziness, insomnia, fatigue, memory loss, thinking and judgement to reduce symptoms. Leukopenia and the future of thrombocytopenia, severe enables impaired hematopoietic function, cause aplastic anemia. If the hematopoietic function completely destroyed, and can be fatal in granular leukocyte disappear, and can cause leukemia.

Women on benzene and its homologues harm than men sensitive, toluene and xylene reproductive function also has a certain influence.

Women of inhaling benzene can also lead to abnormal menstruation, mainly manifested as menorrhagia or disorder, initially because of excessive blood or menstrual bleeding and medical treatment, interval often misdiagnosed as dysfunctional uterine bleeding and relying on treatment. Maternal exposure to toluene, xylene and benzene mixture, pregnancy-induced hypertension syndrome, vomiting of pregnancy and pregnancy anemia and other significant incidence of pregnancy complications.

Benzene can cause fetal defects of congenital.

This issue has attracted the attention of the domestic and foreign experts. Western scholars have reported that during the entire pregnancy period a large number of toluene inhalation women, infants have microcephaly, central nervous system dysfunction and growth retardation, and other defects.
