The effect of two bromfenvinphos impurities: BDCEE and β-ketophosphonate on oxidative stress induction, acetylcholinesterase activity, and viability of human red blood cells.

Numerous research works have shown that synthesis of pesticides leads to the formation of impurities that may substantially enhance pesticide toxicity. In this study, the effect of manufacturing impurities of pesticide bromfenvinphos (BFVF) such as 1-bromo-2-(2,4-dichlorophenyl)-2-ethoxy ethene (BDCEE) and diethyl [2-(2,4-dichlorophenyl)-2-oxo-ethyl] phosphonate (β-ketophosphonate) on human erythrocytes, being significantly exposed to xenobiotics has been studied. The cells were treated with the compounds studied in the concentrations ranging from 0.

[The effect of dioxins on the human organism--epidemiological studies].

For many years dioxins have been the subject of the interest to many research centers due to their widespread occurrence, and high toxicity, and thus they are supposed to be significantly dangerous to humans. In general, dioxins affect all human beings. Workers employed in different branches of industry (chemical, metallurgical and pulp sectors) are especially at high risk.
