西安市表层土壤和地表灰尘中PAEs与理化性质的关系
The Relationship between PAEs and Physicochemical Properties in Surface Soil and Dust in Xi'an City
摘要
Abstract
To determine the correlation between the physicochemical properties and PAEs(phthalates)content in the soil and dust of Xi'an city,the content of PAEs and physicochemical indicators were measured using high-performance liquid chromatography and laser particle size analysis methods,and their correlation was analyzed.The results showed that the average content ofΣ6PAEs in the surface dust of Xi'an city was about 29 times that of the surface soil.In the surface soil,the low-frequency and high-frequency magnetization rates were significantly positively correlated with DMP,DnBP,and Σ6PAEs,while the frequency magnetization rate was significantly negatively correlated with DEP,BBP,DEHP,and Σ6PAEs.Silt was significantly negatively correlated with DEHP and Σ6PAEs,gravel was significantly positively correlated with DEHP,DnOP,and Σ6PAEs,and clay was significantly negatively correlated with Σ6PAEs.In surface dust,TOC was significantly positively correlated with DnOP,and EC was significantly positively correlated with DMP.It was concluded that as the low-frequency and high-frequency magnetization rates increase,the retention capacity of the surface soil for DMP,DnBP,and Σ6PAEs becomes stronger,and as the frequency magnetization rate increases,the retention capacity of the surface soil for DEP,BBP,DEHP,and Σ 6PAEs becomes weaker.DnOP accumulates in dust with high TOC content,and the greater the EC value in surface dust,the greater the accumulation of DMP.关键词
