Content of phthalate esters in soils of Moscow-city

Abstract

The levels of phthalate esters in the upper soil layers of Moscow-city were considered. The sum of concentrations of five phthalate esters (dimethyl phthalate, diethyl phthalate, diisobutyl phthalate, di-n-butyl phthalate, di-(2-ethylhexyl) phthalate) in the soils falls in the range 4,39-397,00 mg/kg (with mean value of 62,70 mg/kg and median of 31,22 mg/kg) and was characterized by lognormal distribution. The shares of those phthalates in the sum of concentrations were 0,6; 0,7; 14,2; 57,9, and 26,6% correspondently. The significant positive correlations were found between concentrations of the phthalate esters. The sum of phthalate concentrations was higher in the soils of reserve and residential areas than that in the soils of roadside and park areas.
