微塑料是为商业用途而产生的,从纺织品中脱落,或由较大的塑料物品分解而产生。最近的报告显示,微塑料在人体组织中积累,可能会对健康产生不利影响。目前,还没有标准化的环境监测系统来跟踪人体组织内的微塑料积累。使用拉曼光谱,我们调查了夏威夷塑料污染的时间暴露,并注意到在过去15年中,废弃胎盘中微塑料的积累显着增加,聚合物的大小和化学成分发生了变化。这些发现为了解太平洋岛屿居民对塑料污染的脆弱性和敏感性提供了难得的见解,并说明了如何将废弃的人体组织用作创新的环境塑料污染监测系统。
Microplastics are created for commercial use, are shed from textiles, or result from the breakdown of larger plastic items. Recent reports have shown that microplastics accumulate in human tissues and may have adverse health consequences. Currently, there are no standardized environmental monitoring systems to track microplastic accumulation within human tissues. Using Raman spectroscopy, we investigated the temporal exposures to plastic pollution in Hawai‘i and noted a significant increase in the accumulation of microplastics in discarded placentas over the past 15 years, with changes in the size and chemical composition of the polymers. These findings provide a rare insight into the vulnerability and sensitivity of Pacific Island residents to plastic pollution and illustrate how discarded human tissues can be used as an innovative environmental plastic pollution monitoring system.
