Summary
This study examined how COVID-19 lockdowns affected microplastic deposition from the atmosphere in an urban area. Reduced human activity during lockdown was associated with decreased atmospheric microplastic concentrations. The findings confirm that local sources — particularly vehicle traffic, industrial activity, and human movement — are significant contributors to urban airborne microplastics.
