METHOD FOR ECOLOGICAL ESTIMATION OF ENVIRONMENTAL HEAVY METAL POLLUTION Russian patent published in 2005 - IPC

FIELD: environmental protection.

SUBSTANCE: invention concerns estimation of environmental pollution using bioassay methods. In particular, method is accomplished through bioindication of controlled area using, as bioindicators, internals (muscles, kidneys, liver) of wild hoofed animals (elk, dear, wild boar). One determines content of heavy metals in these organs placed within an area, compares thus obtained data with maximum permissible concentrations of heavy metals in foods, and estimates heavy metal pollution level of the area from resulted difference. Existence of long-term pollution of a region is judged of from excess concentration of heavy metals in wild hoofed animal kidneys and existence of single release of mercury and lead from that in muscles and liver.

EFFECT: enabled multiple estimation of considerable areas at reduced effort.
