自2018 年1 月1 日新修订的《中华人民共和国水污染防治法》正式施行以来,工业水污染防治措施条款总体执行良好,全国工业水污染防治相关政策措施与设施建设已取得显著进展与成效。国家及相关部门高度重视、各省市积极响应,发布相关政策法规等60 余项;各级部门继续淘汰落后产能,积极推进企业清洁生产,完成了1400 余项工业集聚区污水集中处理设施建设,支撑水污染防治工程举措落地。此外,通过调研评估发现,在部分法律条款执行和工业系统性水污染防治等方面仍然存在落实进展缓慢的情况,存在条款间地区、行业落实不平衡,污染超标排放时有发生,支撑新的国家/地方污水排放标准的监管能力不足等问题。建议以清洁生产为核心抓手,全过程综合控制工业水污染,同时优化调整排水指标,进一步推进环境信息公开,为水污染防治攻坚战和生态文明建设目标任务的完成提供支撑。

Elucidating the spatiotemporal pattern of water quality and algal biomass is crucial for accurately tracing pollution sources and reducing the risk of algal blooms in lake systems. This study analyzed the spatiotemporal variability of water quality and algal biomass in Erhai Lake from 1994 to 2021 using water quality index (WQI), Mann-Kendall test and Sen’s slope combined methods. The potential causes of water quality deterioration and algal biomass dynamics were also elucidated. The results showed that the historical changes in the water environment of Erhai Lake mainly had three stages: satisfactory (1994‒2001), deteriorating (2002‒2010) and improving (2011‒2021). The changes in water quality and algal biomass were primarily affected by total nitrogen, total phosphorus and chemical oxygen demand in different stages. The water environment of Erhai Lake is currently improving significantly, starting in the southern area that is furthest from the sources of agricultural pollution, especially in summer and autumn. This is attributed to the implementation of control measures resulting in lower pollutant loads at particular times and places. Therefore, it is necessary to continue to promote standardized livestock farming, to strengthen rural wastewater collection and to investigate measures such as the interruption of the endogenous cycle.

抗生素在畜禽养殖业中发挥了重要保障作用,但畜禽粪便农用后伴生的抗生素耐药性传播风险日益显现,农田土壤抗生素及其耐药基因的风险管控工作亟待开展。本文总结了农田土壤中抗生素的污染现状,梳理了农田土壤中新兴污染物抗生素管控存在的问题,提出了农田土壤抗生素及其耐药基因的风险管控建议。研究发现,农田土壤抗生素及其耐药基因的污染风险不可忽视,但抗生素类新兴污染物尚未纳入土壤风险管控范围内。应设立严格的兽药应用监管机制,从养殖源头扼制风险的发生概率;制定有机肥中反映耐药性的控制标准,出台技术指南以规范含抗生素粪便的处置与施用,减少抗生素耐药基因进入环境的总量。同时加紧开展环境抗生素耐药性产生和转移的人类健康风险评估研究,实施农田土壤环境抗生素耐药常规监测,发挥风险评估在该类污染物风险管控工作中的作用。

经过多年环境治理,京津冀地区逐步形成了针对大气污染、水污染、固体废弃物污染和生态环境破坏等环境综合治理措施。环境综合治理措施可概括为产业结构调整、能源结构调整、交通运输结构调整、土地利用结构调整和农业农村绿色转型五大类。为了区分环境综合治理措施综合效益大小,本研究采用问卷调查的方法,利用云模型评价法对环境综合效益进行了评价。结果表明,五类环境综合治理措施综合效益的大小排序依次为产业结构调整、能源结构调整、交通运输结构调整、土地利用结构调整和农业农村绿色转型,评价方法和结果为京津冀实施多重污染介质的综合治理措施的选用提供科学依据。
