Investigation of pollution of the soil cover of objects of Sumgait area of the Absheron peninsula with heavy metals

In a paper the investigations of pollution of the soil cover of objects of Sumgait region of the Absheron peninsula with heavy metals have been carried out. The microelements composition of the grey-brown soils of Sumgait region taken from the territory of superphosphate plant has been studied. According to the content of microelements, the investigated soils in the North-Western and southern parts of the Absheron Peninsula have been grouped on a degree of concentration of heavy metals depending on the depth of the investigated soils. The zinc (77.0 mg/kg, at depth 0-16 cm, soil profile no. 03), copper and cadmium (88 mg/kg and 0,36 mg/kg at depth 0-20 cm, soil profile no. 05) have the highest concentration in comparison with other microelements. Depending on the location of the key areas from sources of technogenic emissions, the content of heavy metals is changed. Thus, it has been revealed that in the soils investigated by us on the territory of the superphosphate plant the most important microelements, i.e. heavy metals have been unevenly distributed.
