ОЦЕНКА ВЛИЯНИЯ РАЗЛИЧНЫХ ЗАГРЯЗНИТЕЛЕЙ НА РОСТ И РАЗВИТИЕ РАСТЕНИЙ-РЕМЕДИАНТОВ

Abstract

Phytoremediation is an environmentally safe, inexpensive and aesthetically attractive method of cleaning and restoring areas that have been adversely affected by oil production and refinery enterprises. However, its successful implementation requires plants that are resistant not only to oil, but also to additional pollutants that may be part of its composition or initially present in the soil. In the work, the influence of oil, sodium chloride, heavy metals (cadmium, copper, lead) and herbicides of different groups (Tapir, Fenizan and Chistalan) on the germination, growth of shoots and roots of plants of the Legume and Cereal families was studied to assess the possibility of their use for soil rehabilitation from oil in the presence of associated contaminants. The toxicity for the tested cultures of copper (with the exception of lupine), herbicides Fenizan and Chistalan was shown. The most promising plants for phytoremediation in terms of the studied traits were lupine, barley and oats. They had a high (80% or more) germination, which did not decrease in the presence of pollutants, were capable of elongation of shoots and roots against the background of oil as the main pollutant, and were resistant to some other xenobiotics (lupine – to cadmium, lead and the herbicide Tapir; barley – to cadmium and lead; oats – to cadmium and Tapir).
