RESUMEN
Several microbial clones that could grow on the benz(a)pyrene medium were identified from the soils contaminated with petroleum products. It was shown that benz(a)pyrene could be degraded by the obtained cultures that selectively utilized the carcinogenic molecules of benz(a)pyrene in the presence of other sources of carbohydrate. The authors give recommendations on the biodestruction of benz(a)pyrene and other polycyclic aromatic hydrocarbons under natural conditions in order to improve the oncoecological situation.

The authors propose a rapid and selective method for inverse volta amperometric determination of the levels of cadmium, lead, and copper in blood and hair in microgram/kg. The method requires small blood volumes and no expensive anticoagulants.
