Existing research has analyzed indoor and occupational scenarios, but long-term monitoring of&amp;nbsp;ambient&amp;nbsp;atmospheric&amp;nbsp;microplastics&amp;nbsp;(AMPs), especially&amp;nbsp;in&amp;nbsp;highly polluted urban regions, needs&amp;nbsp;to&amp;nbsp;be further investigated. This study estimated&amp;nbsp;human&amp;nbsp;environmental&amp;nbsp;exposure&amp;nbsp;to&amp;nbsp;AMPs by considering inhalation, dust ingestion, and dermal&amp;nbsp;exposure&amp;nbsp;in&amp;nbsp;three urban functional zones within&amp;nbsp;a&amp;nbsp;megacity. The annual&amp;nbsp;exposure&amp;nbsp;quantity was 7.37 * 104 items for children and 1.06 * 105 items for adults, comparable with the&amp;nbsp;human&amp;nbsp;microplastic consumption from food and water. Significant spatiotemporal differences were observed&amp;nbsp;in&amp;nbsp;the characteristics of AMPs that humans were exposed&amp;nbsp;to, with wind speed and rainfall frequency mainly driving these changes. The annual&amp;nbsp;human&amp;nbsp;AMP&amp;nbsp;exposure&amp;nbsp;quantity&amp;nbsp;in&amp;nbsp;urban green land spaces, which were recognized as relatively low polluted zones, was comparable with that&amp;nbsp;in&amp;nbsp;public service zones and residential zones. Notably, significant positive correlations between the AMP characteristics and the pathogenicity of the airborne bacterial community were discovered. AMP size and immune-mediated disease risks brought by&amp;nbsp;atmospheric&amp;nbsp;microbes showed the most significant relationship, where Sphingomonas might act as the potential key mediator.</style></abstract></record></records></xml>
