Abstract | The results of many researchers’ work have shown the presence of a connection between the chemical composition of plants and the elemental composition of the medium. The plants under the influence of ecological and genetic factors are able to accumulate elements to different degrees [Ilyin, 2006]. In the conditions of technogenic pollution, the environmental factor becomes a priority. The objects of the study were the leaves that were found in the city of Ulyanovsk, and the synanthropic plant of Brom´ us growing on them. The studies have shown that the heaviest metal contaminated area is the Leninsky District. The Zasvijazhsky and Zheleznodorozhny Districts are less contaminated with heavy metals. The Zavolzhsky District is the youngest in terms of using the territory for industrial purposes and the pollution with heavy metals is the lowest here, relative to other areas of the city. The synanthropic plant of Brom´ us has a barrier function to cadmium, lead and zinc, and aluminum, cobalt, copper and nickel are able to accumulate and exhibit resistance to them. |
