Accumulation of heavy metals in soil and plants adjacent to municipal solid waste disposal facility

There are a number of environmental problems in the construction and disposal of solid waste landfills. One of the most important is the negative impact on the environment. The article includes the research findings related to content and accumulation of heavy metals such as zinc, lead, chrome and nickel in soil and plants on the territory adjacent to Shapsha Municipal Solid Waste Landfill, Shapsha settlement, Khanty-Mansiysk area, Khanty-Mansiysk Autonomous Okrug (Yugra), which is 28 km from Khanty-Mansiysk (Tyumen region, Russia). Intensity of heavy metal biological absorption was evaluated. The analysis of obtained results allowed to determine and roughly divide selected plants into two groups by their capability to accumulate heavy metals: accumulators (hyperaccumulators) that accumulate heavy metals both in case of their low and high soil content (Tussilago farfara L., Plantago major L.) and excluders that have limited input of metals to offshoots despite their high concentration in the environment (Tifolium hybridum L., Chamerion angustifolium L.). Identification of new plants prone to hyperaccumulation of heavy metals is important for efficient soil phytoremediation.
