一项长达一年的研究发现,德国的莱茵河每年向北海运送3000至4,700吨垃圾,其中大部分是消费者废物中的塑料。 A year-long study found Germany’s Rhine River carries 3,000–4,700 tonnes of litter yearly to the North Sea, mostly plastic from consumer waste.

在德国科隆进行的一项为期一年的研究发现,莱茵河每年向北海运输3 010至4 707吨垃圾,包括446至697吨塑料,远远超过根据短期数据作出的早期估计。 A year-long study in Cologne, Germany, found the Rhine River transports 3,010 to 4,707 tonnes of litter annually to the North Sea, including 446 to 697 tonnes of plastic, far exceeding earlier estimates based on short-term data. 该研究于2022年11月至2023年11月进行,捕获了17 523块碎片,共约1 955公斤,其中塑料占物品的70%,但只占质量的15%。 The research, conducted from November 2022 to November 2023, captured 17,523 pieces of debris totaling about 1,955 kg, with plastic making up 70% of items but only 15% of the mass. 大多数垃圾来自包装、食品和饮料容器、烟头等消费者废物。 Most litter came from consumer waste like packaging, food and drink containers, and cigarette butts. 科学家强调必须进行长期监测,以准确评估河流污染,并强调公民科学是收集数据的宝贵工具,特别是在重大国际调查方案减少之后。 Scientists stress the need for long-term monitoring to accurately assess river pollution, and highlight citizen science as a valuable tool for gathering data, especially after the decline of major international survey programs.
