The municipal environment total
pollution and pollution of all of its components
(atmosphere, water bodies, soils) by hazardouse
matters lead to their accumulation in living
organisms. According analysis, taking by Ukraine
NAN (National Akademy of Science) Hydrobiology
Institute,the municipal water bodies have high
contents of anthropogenic origin toxicantes.
Through trophic chains they get all organisms
and cause to their death:
The Opechin lake
- in water plants - As, Ni;
- in fish - Pb, Cu, Ba.
The Vyrlitsya lake
- in water plants - Cd, Zn,
Mo;
- in molluscs - Cd, As.
The Raiduzhne lake
- in water plants - Cd, Pb;
- in molluscs - Pb, Cd, As;
- in fish - Ag, As, Mn.
The Syne lake
- in water plants - V;
- in molluscs - Cu, Mo.
- in fish - As.
The Nivka 1 lake
- in water plants - As, Ba,
Mn;
- in molluscs - Cu, Ba, Mn;
- in fish - Hg, Ni, Cr, Ba,
Mn.
The Nivka 2 lake
-in water plants - Cu, Zn, Ni,
Co, Cr, Ba, Mo, I, Mn.
The Dnipro river
- in water plants -Co, Cr;
- in molluscs - Mn;
- in fish - Pb, Zn.
Pollution negatively acts not
only in case of emergency situations, and while
systematic receipting in small doses, though
this influence is usually mediated.
It is necessary to mark that
vegetation, especially arboreal, filters and
sterilizes air from pollution and some exciters
of illnesses. It implements the functions of
original biological filter. The plants ionize
and purify atmosphere from dangerous gases and
admixtures of industrial emissions and motor
transport emissions, decrease influence of
dangerous radiations and enrich the air basin by
oxygen. Also they regulate a water balance and
microclimate of the environment, protect a soil
from erosion, protect and contribute to
reproduction of urban fauna.
So, there is a straight
connection between area and localization of
green plantations and biological diversity. But
because of, as marked above, the number of
population increases, the recreation pressure
increases at the green zones, that are the
centres of animals species and vegetable
groupments.
For example, in connection with
Golosiyivskii forest using with recreation aims,
several species of birds of prey are vanished
and the number the others considerably
decreased.
