Эколого-гигиеническая оценка Tussilago farfara L. , произрастающей на породном отвале угольного разреза «Кедровский»

The article deals with the ecologo-hygienic evaluation of above-ground and underground parts of Tussilago farfara L. and attended embryo-forms by the content of mobile forms of heavy metals. The analysis conducted shows that the highest biological variability coefficient observed in Tussilago farfara L. was for Cu (iron) and Zn (zink). It was established that the content of heavy metals in embryo-forms and plants was higher on young rock dumps as compared with the old ones. It is also ascertained that the content of heavy metals in the vegetal raw stuff, i.e. leaves of Tussilago farfara L., does not exceed the MAC (maximum admissible concentration) and their factual content is at some times less than the standard one.
