摘要
随着溴代阻燃剂的被禁用或限制使用,有机磷酸酯(Organophosphate Esters,OPEs)已成为其主要替代品被广泛应用于各类商业及工业产品。由于OPEs具有毒性且容易释放到环境中,引起了诸多关注。目前已在多种环境基质中发现了OPEs的存在,其中土壤被认为是OPEs的主要赋存介质,而农田土壤与人类的食物链关系密切,其污染问题值得重视。从农田土壤的角度出发,分析了OPEs的主要来源、分布情况和植物的吸收、转运、代谢以及对人体暴露的影响。结果显示,农田土壤中OPEs对人体健康构成的绝对风险不高,但OPEs在土壤环境中持续积累会对人体产生潜在威胁,因此有必要进一步探讨其环境行为及其健康风险。
With the access to brominated flame retardants being banned or restricted,organophosphate esters(OPEs)have been widely used as the main substitutes in a variety of commercial and industrial products.They have raised great concern because of their toxicity and easy release into the environment.At present,OPEs have been found in various environmental substrates,among which soil is considered to be the main sink of OPEs.Farmland soil is closely related to human food chain,and its pollution problem deserves attention.This paper analyzed the main source and distribution of OPEs,as well as the uptake,translocation and metabolism of plants and their impact on human exposure from the perspective of farmland soil.The results showed that the absolute risk of OPEs to human health in farmland soil was not high,but the continuous accumulation of OPEs in soil environment would cause potential threats to human health,so it is necessary to further explore the environmental behavior and health risks of OPEs.
