Some aspects of toxic secretions accumulation in mammalian organisms
Аннотация
А qualitative method was used in the study. The article describes the
terrain of the studied territories, the heterogeneity of the biotic component,
the description of the aspects of the accumulation of toxic excretions on
mammalian organisms.
During the investigation, the main environmental pollutants in the
Pavlodar region and their impact on the organisms of mammals were
studied. Catching of animals is carried out according to standard methods
using accounting lines: trap-lines and trapping grooves. The aspects of
bioaccumulation of fluorine, benz (a) pyrene, heavy metals (lead, zinc, arsenic,
mercury) in the organisms of animal populations inhabiting the urban areas of
Pavlodar region have been determined. The main fluoride depot is bone tissue.
Heavy metals tend to accumulate in the fur of mammals, as well as in
the liver, kidneys, lungs and genitals. The most dangerous for animal health
is benzo (a) pyrene, which can accumulate in adipose tissue. Benz (a) pyrene,
being the strongest mutagen, can lead to the formation of malignant tumors.
The degree of accumulation of toxic secretions directly depends on the habitat
of animals and the type of food. It was found that contaminants can accumulate
in bone, connective and epithelial tissues.
