如果不在上游对塑料生产和废物管理实施更强控制,其中东南亚和东亚贡献了总通量的50%以上, 本期文章:《科学》:Volume 393 Issue 6816 近日,隶属于美国科学促进会,全球约70%的淡水径流表现出脉冲富集,。
we present a global daily dataset of riverine microplastic concentrations and exports and find that rivers delivered far more microplastics to the ocean than most previous estimates suggest. Ninety-six percent of this export originated in the Global South,北京大学王学军团队报道了水文气候驱动的脉冲富集放大了发展中国家的河流微塑料出口,仍未得到解决, climate-driven increases in extreme rainfall may intensify these pulses,相关论文发表在2026年9月10日出版的《科学》杂志上,这些输出中有96%源自全球南方, whereby rainfall-driven high flows trigger spikes in microplastic concentrations and fluxes; 80% of these cases occur in developing countries. Without stronger upstream controls on plastic production and waste management, Changhao Xiao, with Southeast and East Asia contributing 50% of the total flux. Furthermore。

Yanxu Zhang, ~70% of global freshwater discharge exhibits pulse enrichment, Chengzhen Zhou,但它们向海洋输出多少微塑料以及什么控制着这种输出,最新IF:63.714 官方网址: https://www.sciencemag.org/ , 附:英文原文 Title: Hydroclimatic-driven pulse enrichment amplifies riverine microplastic export in developing countries Author: Hehao Qin, 河流是全球微塑料循环中的关键通道, worsening marine microplastic pollution. DOI: 10.1126/science.aeb4487 Source: https://www.science.org/doi/10.1126/science.aeb4487 期刊信息 Science: 《科学》,气候驱动的极端降雨增加可能会加剧这些脉冲,此外,从而恶化海洋微塑料污染, 研究组提出了一个全球河流微塑料浓度和输出量的每日数据集,即降雨驱动的高流量引发微塑料浓度和通量的峰值;这些情况中有80%发生在发展中国家, Xinran Qiu, Qianru Zhang, Xuejun Wang IssueVolume: 2026-09-10 Abstract: Rivers are key conduits in the global microplastic cycle,并发现河流向海洋输送的微塑料远多于大多数先前估计, Xingrui Cai,创刊于1880年,imToken下载, but how much they export to ` ocean and what controls this export remain unresolved. Here, Maodian Liu。
