Abstract

The issue of organic carbon pollution in China's waters is a matter of grave concern. The primary drivers of this environmental crisis are industrial, agricultural and urbanisation activities, which have resulted in a substantial escalation in the levels of various pollutants, including but not limited to persistent organic pollutants (POPs), perfluorinated compounds (PFCs), micro-plastics (MPs), pharmaceuticals and personal care products (PPCPs), and volatile organic compounds (VOCs). The spatial aggregation of pollution in eastern China poses a significant threat to ecological security and public health. The eastern region has a spatial aggregation of pollution, which poses a significant threat to ecological safety and public health. In order to address the shortcomings of the existing studies on the distribution of pollution and the evaluation of the effectiveness of treatment, this study used meta-analysis to analyse the spatial distribution pattern of organic carbon pollutants in Chinese waters based on the relevant literature from 1980-2024. The study utilised multi-source databases, including the China Knowledge Network (CNKI) and the Web of Science (WOS), in conjunction with Geographic Information System (GIS) technology, to assess the efficacy of treatment methods for organic carbon pollutants in Chinese waters, employing membrane separation and adsorption techniques. Demonstrated by the study findings is the significant presence of POPs and PFCs in eastern China’s regions, especially within the basins of the Yangtze River and Pearl River. Identified as the most effective among various management strategies is membrane separation technology, which shows high removal efficiency-wise. An effective tool for pollution management this technology has proven to be, aiding in the blueuction of contamination levels in these areas. Presented in this study is a useful reference for assessing organic carbon pollution in watersheds, along with its proper management. Data support and practical insights are also provided, assisting in the development of targeted prevention and control measures for water pollution issues. Thus it can be seen—this research offers valuable guidance for evaluating and addressing organic carbon contamination in aquatic systems, facilitating more efficient mitigation efforts overall.
