A significant fraction (45%) of global environmental losses of plastics stems from mismanaged landfills and open dumps located mainly in the Asian region. These lost plastics cause substantial impacts on the ecosystems, human health and economy. To date, no large-scale quantification has ever been made to estimate urban, national, or global risks of plastics losses from landfills, covering all relevant pathways, like wind blowing, precipitation/runoff, or flooding. Here, we have developed a novel framework to categorize urban centers into different risk levels based on a trivariate risk assessment model. We applied it to entire India, building on landfill data and modeling pertaining to 496 Indian urban centers with populations larger than 0.1 million inhabitants. Results show that 11% of these cities present severe and very high risk levels, including largely populated metropolitan cities like Mumbai and Delhi. This nationwide assessment can help policy-makers identify and prioritize urban centers in dire need of actions to limit environmental losses of plastics. Owing to the importance of landfills as a plastics release source, such decision support offers strong opportunities to curb plastics pollution globally.

印度垃圾填埋场对环境造成塑料损失的风险

全球塑料环境损失的很大一部分(45%)源于管理不善的垃圾填埋场和主要位于亚洲地区的露天垃圾场。这些丢失的塑料对生态系统、人类健康和经济造成重大影响。迄今为止,尚未对城市、国家或全球垃圾填埋场造成的塑料损失风险进行大规模量化,涵盖所有相关路径,如风吹、降水/径流或洪水。在这里,我们开发了一个新的框架,基于三元风险评估模型将城市中心分为不同的风险级别。我们将其应用到整个印度,建立在垃圾填埋场数据和与 496 个人口超过 10 万居民的印度城市中心相关的模型上。结果表明11%这些城市中的大多数呈现出严重和非常高的风险水平,包括人口众多的大都市,如孟买和德里。这项全国性评估可以帮助政策制定者确定并优先考虑急需采取行动限制塑料对环境造成损失的城市中心。由于垃圾填埋场作为塑料释放源的重要性,这种决策支持为遏制全球塑料污染提供了强有力的机会。
