Abstract

Pesticide residues and their accumulation in marine environments pose potential threats to the ecosystem balance and human health. Assessment of pesticide residue levels and ecological risks in marine waters is insufficient. Therefore, we conducted a quantitative analysis of four different categories of pesticides in the surface waters of the Bohai Sea and Yellow Sea in China. A comprehensive ecological risk assessment framework was constructed based on the importance of ecosystem services, utilizing the risk quotient (RQ) and entropy weighting methods to evaluate the multi-pesticide ecological risks in the study area. Thirteen pesticides were detected in the surface waters, with total concentration levels ranging from 8.18 to 80.60 ng/L, and the herbicide Atrazine and insecticide Imidacloprid were found at the highest levels. Concentration levels were higher in the Bohai Sea than in the Yellow Sea, and the highest area was mainly located on the coast of Shandong Province, China. The ecological risk of multi-pesticide pollution was the highest in the coastal regions of Shandong and was associated with Atrazine and Acetamiprid. Source analysis suggested that triazine herbicide and neonicotinoid insecticides are predominantly land-sourced, whereas sulfonylurea herbicides are primarily atmospheric. This study provides valuable support for formulating relevant environmental protection policies and measures.

渤海、黄海多农药污染生态风险综合评价方法

海洋环境中农药残留及其积累对生态系统平衡和人类健康构成潜在威胁。对海水中农药残留水平和生态风险的评估不足。因此，我们对中国渤海和黄海表层水体中4种不同类型的农药进行了定量分析。基于生态系统服务功能的重要性，构建了综合生态风险评价框架，运用风险商（RQ）法和熵权法对研究区多农药生态风险进行评价。地表水共检出13种农药，总浓度在8.18 ~ 80.60 ng/L之间，其中除草剂阿特拉津和杀虫剂吡虫啉含量最高。渤海的浓度水平高于黄海，最高的区域主要分布在山东省沿海。山东沿海地区多农药污染生态风险最高，与阿特拉津和啶虫脒相关。来源分析表明，三嗪类除草剂和新烟碱类杀虫剂主要来自陆地，而磺酰脲类除草剂主要来自大气。该研究为制定相关的环境保护政策和措施提供了宝贵的支持。

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.
