The study applied a tiered ecological risk assessment method to evaluate the long-term status and trend of the ecological risks of dissolved heavy metals from 2011 to 2019 in the Yangtze River Estuary and Zhejiang coastal waters, China. The results for spring, summer, and autumn of 2019 indicated that Pb, Cd, and Zn posed no adverse ecological risk, Cu posed a potential ecological risk, and As posed an ecological risk. The annual results from 2011 to 2019 suggested that Pb, Cd, and Zn posed no adverse ecological risks, and As and Cu posed an ecological risk. The trend analysis in the nine years showed that the ecological risk of Cu is gradually decreasing, while that of As is still a concern. The overall trend is attributed to the environmental protection policies that reduced these contaminants' terrestrial sources and atmospheric sources.
本研究采用分层生态风险评估方法，评估了 2011 年至 2019 年长江口和浙江近岸海域溶解态重金属的生态风险的长期状况和趋势。2019 年春季、夏季和秋季的结果表明，Pb、Cd 和 Zn 没有造成不良生态风险，Cu 造成了潜在的生态风险，而 As 造成了生态风险。2011 年至 2019 年的年度结果表明，Pb、Cd 和 Zn 没有造成不良生态风险，而 As 和 Cu 造成了生态风险。九年的趋势分析表明，Cu 的生态风险正在逐渐降低，而 As 的生态风险仍然令人关注。这种整体趋势归因于环境保护政策，这些政策减少了这些污染物的陆地来源和大气来源。
