Assessment of total soil contamination with heavy metals in the coastal area of the cape peschany

Abstract

In the autumn of 2018, in the coastal zone of the Caspian region, namely, in the area of Cape Peschany, scientific field studies of the state of the soil were carried out. 7 test sites (TS) were investigated.
Studied more than 30 soil samples taken from depths of 0-5 and 5-20 cm spectrophotometer laboratory
HACH DR-2400 (USA) determined the total contents of heavy metals (HM). For analyz ephase three
total soil pollution (TSP) or TS, using different approaches, the used value of the content of chemical
elements in the background area TS-the background. The soil of the Karakia-Karakol reserve was used as
a background. Only the value of KC>1 was taken into account in the calculation of ZC. Perhaps in this
regard, for TS-3 (garden), the lowest total soil pollution index was obtained, including negative values
of Z
C(r). The results of the calculations, only on TS-2, ZСТ=16.5 level of contamination moderate threat
on the remaining TS and within the acceptable level. Statistical processing of the results in the program
Statistica 10 showed that the criterion of Kruskal-Wallis is statistically significant for the elements of Cr,
Cd, Cu and Co.
Key words: Caspian Sea, Cape Peschany, soil, heavy metals, total pollution.
