The analysis of heavy metals in arable soils of the administrative districts of the Ulyanovsk region was held for the period 1995 to 2011. We have explored average weighted content of lead, cadmium, zinc, copper, nickel, as well as cases of soil contamination with heavy metals, namely exceeding their limits of allowable concentrations. The maximum of average weighted contents of four - three heavy metals simultaneously was recorded in Novospasskoe, Starokulatkinsky, Inza, Tsilninsky areas. The excess of the limits of allowable concentrations were observed in Sengileevsky, Melekessky, Sursko, Karsunsky, Mainsky, Nicholas, Starokulatkinsky, Inza, Kuzovatovsky, Novospasskoe, Cherdaklinsky areas. These excess are local, but nevertheless they may have a negative impact on the health status of long-term resident in the area of population and cause diseases of the endocrine, nervous and skeletal - muscular systems.
