Abstract

Phthalate esters (PAEs) are widely detected in the environment, posing potential threats for human health. In this study, 23 PAEs were determined in 68 paired urban soil and surface dust samples and four dustfall samples collected from the arid city of Urumqi in China for their sources and health risks. The results showed that the total concentration of 23 PAEs in urban soil, surface dust and dustfall of Urumqi averaged 879, 2.17 × 10⁴ and 4.38 × 10³ ng/g, respectively, dominated by di-n-butyl, di-isobutyl, bis (2-ethylhexyl) and di-isononyl phthalates. Higher concentrations of PAEs in urban soil and surface dust were found in the south, southwest and northeast of Urumqi. The total deposition flux of dustfall-borne 23 PAEs averaged 521 ng/m²/d. PAEs in urban soil and surface dust of Urumqi were associated with the use of plasticizers (30.3 and 32.5 %), building materials (25.0 and 26.5 %) and cosmetics and personal care products (19.9 and 22.8 %) as well as the emission of traffic (24.8 and 18.2 %). The bio-accessibility of PAEs in the two media was controlled by their physicochemical properties. The non-cancer (< 1) and cancer (< 1 × 10⁻⁶) risks were relatively low for human exposure to PAEs in urban soil and surface dust. The current research results enrich understanding for pollution behaviors of PAEs in the environment.
