The article gives an assessment of resistance of the brown typical soil of the Utrish national reserve to pollution with heavy metals (Cr, Cu, Ni, Pb) and oil on biological indicators

Negative impact of oil on biological properties of soils right after pollution is shown in the article. Eventually, there is their restoration. However, even in some years after pollution, the biological properties of soils aren't restored completely

We studied the effects of heavy metal pollution on soil phytotoxicity cities of the Rostov region. The research objects were the soils of urbolandscape towns: Taganrog, Novocherkassk, Gukovo, Shakhty, Azov. The study of the soil pollution with heavy metals was recorded in Gukovo, Shakhty, Taganrog. The degree of pollution of the studied cities form the following row: Gukovo > Shakhty > Taganrog > basics > Novocherkassk. The research was carried out in 2011-2015 at the Department of ecology and environmental Sciences of southern Federal University. In most cases, there was a direct correlation between pollutant concentration and the degree of deterioration of the studied soil properties. Used biological indicators are informative for monitoring of urban soils polluted with heavy metal. The degree of informativity of biological indicators form the following row: root length > germination >length of shoots. The results of the study can be used for monitoring and diagnosing the condition of contaminated soils, in the assessment of environmental impact, risk assessment of natural and synthetic disasters, the development of regional standards on the content of heavy metals in soil and in other environmental and industrial activities
