摘要: 苯系物(BTEX)系苯、甲苯、乙苯和二甲苯的统称,由于其具有高毒性而引起了人们的广泛关注。研究BTEX在土壤中的环境行为,有助于准确了解其在环境中的归宿以及评价其对生态系统和人类健康的风险性。本文从吸附-解吸、挥发、淋溶和降解等4个方面,对BTEX在土壤中环境行为的研究进展进行了综述,特别对影响BTEX在土壤环境中的吸附-解吸行为的不同因素进行了详细概述,并对今后的研究方向进行了探讨。

Abstract: BTEX is a general designation of benzene, toluene, ethylbenzene and xylene, which has been received wide attention because of its high biological toxicity. To investigate its environmental behavior in soil would help to understand its environmental fate and to evaluate its risks to ecosystems and human health. This paper summarized the environmental behavior of BTEX in soil from the aspects of adsorption-desorption, volatilization, eluviation, and degradation, with the focus on the factors affecting the adsorption and desorption of BTEX in soil. The future research directions were also discussed.
