Abstract

BDE-47 is the most abundant and toxic congener in the marine environment. Assessing the ecological risk of BDE-47 in seawater is of great importance to protect the marine species. However, the ecological risks of BDE-47 on marine species is still limited. In the present study, the hazardous concentrations for 5 % of species (HC₅) values of BDE-47 were derived by species sensitivity distributions (SSD), the short-term water quality criteria (SWQC) and long-term water quality criteria (LWQC) were acquired from HC₅. Moreover, the marine ecological risk of BDE-47 was assessed by the risk quotient (RQ) method in the coastal area of China. The SWQC and LWQC were 1.06 μg/L and 0.61 μg/L, respectively. According to published literature, the concentrations of BDE-47 ranged from undetected to 9.06 ng/L, BDE-47 has no risk to marine species in most coastal areas, but might show low risk for a long exposure time in the coastal mariculture area of China. This study provides a new approach for the derivation of the WQC and the ecological risk assessment of BDE-47, which is essential for the protection of marine species and provides guidance to manage the concentration of BDE-47 for administrative department.

基于物种敏感性分布法的海洋环境BDE-47生态风险评价

BDE-47是海洋环境中含量最多、毒性最强的同系物。评估BDE-47在海水中的生态风险对保护海洋物种具有重要意义。然而，BDE-47对海洋物种的生态风险仍然有限。本研究采用物种敏感性分布法（SSD）推导出BDE-47中5%物种（HC5）的有害浓度值，并从HC5中获得短期水质标准（SWQC）和长期水质标准（LWQC）。采用风险商（RQ）法对BDE-47在中国沿海地区的海洋生态风险进行了评价。SWQC为1.06 μg/L， LWQC为0.61 μg/L。根据已发表的文献，BDE-47的浓度范围从未检测到到9.06 ng/L， BDE-47在大多数沿海地区对海洋物种没有风险，但在中国沿海海水养殖区，BDE-47在长时间暴露后可能呈现低风险。本研究为BDE-47的WQC的推导和生态风险评估提供了新的途径，对海洋物种的保护至关重要，也为行政管理部门对BDE-47浓度的管理提供了指导。

期刊介绍： Marine Environmental Research publishes original research papers on chemical, physical, and biological interactions in the oceans and coastal waters. The journal serves as a forum for new information on biology, chemistry, and toxicology and syntheses that advance understanding of marine environmental processes. Submission of multidisciplinary studies is encouraged. Studies that utilize experimental approaches to clarify the roles of anthropogenic and natural causes of changes in marine ecosystems are especially welcome, as are those studies that represent new developments of a theoretical or conceptual aspect of marine science. All papers published in this journal are reviewed by qualified peers prior to acceptance and publication. Examples of topics considered to be appropriate for the journal include, but are not limited to, the following: – The extent, persistence, and consequences of change and the recovery from such change in natural marine systems – The biochemical, physiological, and ecological consequences of contaminants to marine organisms and ecosystems – The biogeochemistry of naturally occurring and anthropogenic substances – Models that describe and predict the above processes – Monitoring studies, to the extent that their results provide new information on functional processes – Methodological papers describing improved quantitative techniques for the marine sciences.
