微塑料在整个生态系统中无处不在，但对人类的暴露风险尚未得到解决。以美国人的饮食为重点，我们评估了常用食物中微塑料颗粒的数量与其推荐的每日摄入量的关系。还探讨了微塑料吸入的可能性以及饮用水源如何影响微塑料的消耗。我们的分析使用了来自26项研究的402个数据点，代表了超过3600个处理过的样本。评估美国人大约15%的热量摄入，我们估计每年的微塑料消耗量在39000到52000个颗粒之间，具体取决于年龄和性别。这些估计增加到74000和121000时，吸入考虑。此外，仅通过瓶装水达到推荐饮水量的人每年可能额外摄入90000个微塑料，而仅饮用自来水的人则为4000个微塑料。这些估计数有很大的差异;然而，由于方法和数据的限制，这些数值可能被低估。
Microplastics are ubiquitous across ecosystems, yet the exposure risk to humans is unresolved. Focusing on the American diet, we evaluated the number of microplastic particles in commonly consumed foods in relation to their recommended daily intake. The potential for microplastic inhalation and how the source of drinking water may affect microplastic consumption were also explored. Our analysis used 402 data points from 26 studies, which represents over 3600 processed samples. Evaluating approximately 15% of Americans' caloric intake, we estimate that annual microplastics consumption ranges from 39000 to 52000 particles depending on age and sex. These estimates increase to 74000 and 121000 when inhalation is considered. Additionally, individuals who meet their recommended water intake through only bottled sources may be ingesting an additional 90000 microplastics annually, compared to 4000 microplastics for those who consume only tap water. These estimates are subject to large amounts of variation; however, given methodological and data limitations, these values are likely underestimates.
