Urbanization Development, Growth Of Industrial Targets And Constant

Urbanization development, growth of industrial targets and constant increase in density of a municipal transportation is accompanied by a number of negative influences, and first of all an excessive congestion in atmosphere various gazo - and pollution. It often leads to irreversible destructions natural and biospheres as a whole. Plants possess good adaptable ability, but they negatively react to presence in environment, even in small doses, toxic substances. The most aggressive action on plants is rendered by exhausts of motor transport which rather easily take root into circulation of substances of the nature ( sulfurs (SO2), nitrogen (NO2), lead connections (Rv), hydrocarbons ( m m). Plants are stores of polluting substances. The congestion of these substances can occur as in bodies of plants (leaves, fruits, roots, etc.), and outside. Depending on duration and intensity of influence of polluting substances on plants it leads to their damage: to infringements of physiological functions, , to premature leaf fall or , depressions of growth of parts of plants functionally important or intended for use.
