| 英文摘要 | Microplastics are found in continental and oceanic waters worldwide, but their spatial distribution shows an intricate pattern. Their driving factors remain difficult to identify and widely discussed due to insufficient and unstandardized monitoring data. Here, based on in situ experiments and hundreds of river samples from the Qinghai-Tibet Plateau, we formulate a model to standardize aquatic microplastic measurements. The model was applied to existing data on a global scale. These data are standardized to a 20 mu m mesh size, resulting in a new spatial distribution of aquatic microplastic densities, with average concentrations of 554.93 +/- 1352.42 items/m(3) in Europe, 2558.90 +/- 4799.62 in North America and 1741.94 +/- 3225.09 in Asia. Excessive contaminations (microplastic concentration > 10(4) items/m(3)) are in the Yangtze River, the Charleston Harbor Estuary, the Bodega Bay and the Winyah Bay. We show that, based on these standardized concentrations, new driving factors could be used to predict the global or regional microplastic distribution in continental waters, such as the Human Development Index with a correlation of 75.86% on a global scale, the nighttime lights with a correlation of 37.26 +/- 0.30% in Europe and 39.02 +/- 0.54% in Asia, and the Mismanagement Plastic Waste with a correlation of 61.21 +/- 19.86% in North America. Mapping standardized concentrations of aquatic microplastics enables a better comparison of contamination levels between regions and reveals more accurate hotspots to better adapt remediation efforts and future plastic pollution scenarios. |
