MORPHO-PHYSIOLOGICAL CHANGES IN WOODY PLANTS UNDER AN AIR POLLUTION
The literature (mainly domestic) about the use of plants in the estimation of contamination of environment is considered. A conclusion is done, that arboreal plants by virtue of features of their metabolism mainly utillize for indication the contamination of atmospheric air. For determination of total levels of the contamination of atmosphere more suitable the physical-biochemic, morphometric and anatomic indexes of the state of plants which can be utillized and for the estimation of total contamination of soils. Control of contamination of atmosphere by the concrete toxicant is possible to carry out on the indexes of TIC (total index of concentration) and Ce (coefficient of enriching) of leaves and pine-needle. Index of biological absorption of arboreal plants as quantitative description of contamination of soils by concrete toxicant of the little use, because at the high level of the toxicant maintenance in the soils there is a suppression of its biological absorption by plants.
