概括

源控制立法,如禁止酸盐在洗剂中,是迅速减少河流污染的最有效方法. 优先考虑这些措施可以改善水质管理.

科学领域:

环境科学环境科学
水质管理水质管理
环境政策环境政策

背景情况:

河流水质的变化遵循了受管理干预影响的退化和恢复轨迹.
不同的立法方法 (源控制,使用相关,管道末端) 对水质的相对有效性仍然不清楚.
(P) 是地表水质的关键指标,也是对温控制立法的一个目标.

研究的目的:

量化点源负荷与河水质量之间的关系.
分析不同治理层面的各种P相关立法在不同治理层面的有效性.
评估立法干预对鲁尔河多十年轨迹的影响.

主要方法:

结合了档案数据,文献评论和与当代目击者的采访.
分析了来自欧盟,国家,州和地方的P相关立法.
与鲁尔河测量总 (TP) 度相关的立法发展.

主要成果:

到1980年,管道末端措施 (WWTP) 将TP输入量减少了38%.
自从1990年以来,1981年禁止酸盐洗剂以来,WWTP影响的TP减少了36%.
综合措施将WWTP废水TP到2021年减少92%.

结论:

源控制措施,如洗剂再配方,是制排放的最快,最有效的方法.
优先考虑源控制将为有效的水质决策和政策提供信息.
结果为通过层次治理来管理其他点源污染物提供了洞察力.

The Phosphorus Cycle

The Phosphorus Cycle

Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.
