Don River每年向安大略湖释放5 000亿微塑料,主要来自建筑泡沫、轮胎和退化塑料。 The Don River releases 500 billion microplastics yearly into Lake Ontario, mainly from construction foam, tires, and degraded plastics.

多伦多的唐河每年向安大略湖释放大约5 000亿微塑料颗粒——相当于36 000公斤,远远超过更大的塑料碎片。 The Don River in Toronto releases about 500 billion microplastic particles—equivalent to 36,000 kilograms—into Lake Ontario each year, far surpassing larger plastic debris. 多伦多大学切尔西·洛克曼(Chelsea Rochman)领导的一项经同行审查的研究发现,微塑料来自建筑泡沫、轮胎、塑料颗粒以及诸如袋和湿巾等退化的单用途物品。 A peer-reviewed study led by University of Toronto’s Chelsea Rochman found microplastics come from construction foam, tires, plastic pellets, and degraded single-use items like bags and wet wipes. 风暴之前、期间和之后的测量结果显示,污染没有增加,表明如果消除污染源,河水可以恢复。 Measurements before, during, and after storms showed no spike in pollution, suggesting the river could recover if sources are eliminated. 专家敦促改善废物管理、基础设施升级和禁止某些塑料,因为多伦多投资30亿美元,以减少下水道溢出。 Experts urge better waste management, infrastructure upgrades, and bans on certain plastics, as Toronto invests $3 billion to reduce sewer overflows.
