Occurrence, distribution and human exposure of phthalic esters in road dust samples across China

203 road dust samples were conducted across China covering 28 provinces from January to February，2016 to comprehensively investigates the occurrence, distribution and human exposure of 21 phthalic esters (PAEs). The concentration of Σ21PAEs in road dust ranged from 2.3 to 531 mg/kg, with a mean conc...

Description
Summary:203 road dust samples were conducted across China covering 28 provinces from January to February，2016 to comprehensively investigates the occurrence, distribution and human exposure of 21 phthalic esters (PAEs). The concentration of Σ21PAEs in road dust ranged from 2.3 to 531 mg/kg, with a mean concentration of 64.1 ± 57.2 mg/kg. DEHP, DnBP and DiBP were the dominant components accounting for 63.3–97.9% (mean: 92.1%) of the Σ21PAEs. Significant Pearson correlation (r = 0.51, p
