One Of Serious Sources Of Pollution Surrounding Means

One of serious sources of pollution surrounding means for today is transport. At motor transport work the considerable quantity of connections is thrown out in atmosphere: carbon II (WITH), hydrocarbons on gasoline and kerosene ( ), nitrogen (IV) (NO2), sulfurs (SO2), lead connections (Pb). These emissions fatally influence the agricultural crops located near to a motorway. It is shown that pollution of vegetative weight of plants on fields is marked even on removal in 100 m from a roadbed. And only on distance of 150 m from a motorway concentration of toxic substances in vegetative weight comes nearer to the control. Among numerous to the person the place is occupied with heavy metals which are the most toxic. Following chemical elements concern very toxic metals: , With, Ni, Cu, Sn, As, Se, Te, Rb, Ag, Cd, Au, Hg, Sb, Rt. Some of these elements are known as microcells, the big which physiological importance in the course of a metabolism not only is scientifically proved, but used in practice of agriculture and medicine.
