ИЗУЧЕНИЕ ПОТЕНЦИАЛА ПОЛЕВЫХ КУЛЬТУР ДЛЯ ЦЕЛЕЙ ФИТОРЕМЕДИАЦИИ ПОЧВ, ЗАГРЯЗНЕННЫХ ФТОРИДАМИ АЛЮМИНИЕВОГО ПРОИЗВОДСТВА

Abstract

Поиск растений, обладающих высокой аккумулирующей способностью и толерантностью к фто­ридам, является необходимым условием эффективной фиторемедиации пахотных почв, загряз­ненных аэровыбросами алюминиевого производства. Первостепенной задачей для исследований должно быть изучение потенциала возделываемых в регионе сельскохозяйственных растений, как наиболее адаптированных к конкретным почвенно-климатическим условиям. В полевых опытах, проведенных одновременно на незагрязненной и загрязненной аэровыросами ИркАЗа серых лесных почвах, у пяти видов полевых культур, распространенных в земледелии Байкальской Сибири, были определены вынос фтора надземной массой растений и биоаккумуляционный фактор. Показано, что наибольшим потенциалом для фитоэкстракции фторидов из загрязненных почв обладают донник желтый и редька масличная. Полученные результаты расширяют представление о видах-кандидатах, перспективных для целей фиторемедиации, которые в дальнейшем могут быть ис­пользованы при оздоровлении загрязненных фторидами агроландшафтов.

The search of plants with high storage accumulating capacity and tolerance to fluorides is a prerequisite for effective phytoremediation of arable soils, contaminated by aluminum production emissions. The primary objective of the research was to study the potential of local agricultural crops, as the most adapted to the specific soil and climatic conditions. The fluorine removal by above-ground biomass and bioaccumulation factor for five cropspecies, which are widespread in the Baikal Siberia agriculture,were determined in the field experiments carried out simultaneously in unpolluted and contaminated grey forest soils. Melilótus of­ficinális and Raphanus sativus showed the greatest potential for phytoextraction of fluoride from the con­taminated soil. The results extend the conception of candidates for phytoremediation purpose and can be used further for the decontamination of fluorides in polluted agricultural landscapes.
