Abstract

Organophosphate esters (OPEs) are emerging pollutants and used extensively in industrial production as alternative to the traditional flame retardants. This study investigated the contamination characteristics and health risks of OPEs in 104 mollusks from 15 cities along the coastal region of South China. Σ8OPEs ranged from 48.2 to 1937 ng/g dw, with a mean value of 295 ng/g dw. TDCIPP, TCPP, and TCEP were the dominant OPEs. Different spatial distributions were observed, with higher concentrations in Guangdong Province. A statistically positive but non-significant linear correlation was found between the trophic level of mollusk and OPEs concentration. The trophic magnification factors were >1, suggesting that OPEs have the potential to biomagnify in mollusks. OPEs in mollusks pose low non-carcinogenic and carcinogenic risks to consumers. This study provides an important basis for managing the safety risks associated with OPEs in mollusks.

华南沿海软体动物体内有机磷酸酯的污染特征与风险评估。

有机磷酸酯（OPEs）是一种新出现的污染物，在工业生产中被广泛用于替代传统的阻燃剂。本研究调查了华南沿海地区 15 个城市 104 种软体动物体内 OPEs 的污染特征和健康风险。结果表明，Σ8OPE 的含量范围为 48.2 至 1937 纳克/克干重，平均值为 295 纳克/克干重。TDCIPP、TCPP 和 TCEP 是主要的 OPE。观察到不同的空间分布，广东省的浓度较高。软体动物的营养级与 OPEs 浓度之间存在统计学上的正线性相关，但不显著。营养放大系数大于 1，表明 OPEs 有可能在软体动物体内产生生物放大作用。软体动物中的 OPE 对消费者构成的非致癌和致癌风险较低。这项研究为管理与软体动物中 OPE 相关的安全风险提供了重要依据。

期刊介绍： Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
