ARTICLE ANNOTATION

quote
The article describes the contamination of irrigated grassland soils with copper and lead, which are distributed around the international highway «Tashkent-Termez» M-39. As a result of automobile activity, the content of copper and lead in these soils gradually increased up to a distance of 20-30 meters from the road. The maximum content of both elements was determined in field No. 4, selected from the U.Nosir massif of the Ak-Altin district. Total copper content was 108.0 mg/kg and lead content was 96.4 mg/kg in soil samples taken 25 meters from the highway of this field. This indicator is 1.96 times higher than the permissible limit of copper (55 mg/kg), 2.84 times higher than the background indicator (38 mg/kg), 3 times higher than the permissible limit of lead (32 mg/kg per 1 kg of soil) and 6.4 times higher than the background indicator (15 mg/kg per 1 kg of soil). After a distance of 20-30 meters from the road, it was noted that the amount of heavy metals gradually decreases in the studied fields.
