The content and distribution pattern of phthalate esters in the top soil layers in Moscow have been determined. The total content of five of them (dimethyl phthalate, diethyl phthalate, diisobutyl phthalate, din-butyl phthalate, and di-(2-ethylhexyl) phthalate) in city soils is within the range of 4.39–397.00 mg/kg (the mean is 62.70 mg/kg and the median is 31.22 mg/kg) and is characterized by a lognormal distribution. The participation of these compounds in the total content of phthalates is 0.6, 0.7, 14.2, 57.9, and 26.6%, respectively. A significant positive correlation between the contents of the phthalate esters in soil has been revealed. The total amount of phthalates in soil was the highest in the reserve and residential areas and the lowest in the residential-transport and park-recreational zones.

莫斯科土壤中邻苯二甲酸酯的含量

确定了莫斯科表层土壤中邻苯二甲酸酯的含量和分布规律。城市土壤中五种成分的总含量（邻苯二甲酸二甲酯，邻苯二甲酸二乙酯，邻苯二甲酸二异丁酯，邻苯二甲酸丁丁酯和邻苯二甲酸二（2-乙基己基）酯）在4.39–397.00 mg / kg的范围内（平均值为62.70 mg / kg，中位数为31.22 mg / kg），其特征在于对数正态分布。这些化合物在邻苯二甲酸酯总含量中的参与度分别为0.6、0.7、14.2、57.9和26.6％。已经揭示了土壤中邻苯二甲酸酯含量之间的显着正相关。土壤中邻苯二甲酸盐的总量在保护区和居民区最高，而在居民运输区和公园休闲区最低。
