Evaluation of new pollutants in organic fertilizers and their environmental impact
Scientific and standardized application of organic fertilizers is of great significance to improve soil fertility,reduce ecological environment pollution,and ensure national food security.The impacts and risks of new pollutants such as microplastics,antibiotics and antibiotic resistance genes,and persistent organic pollutants on soil ecological environment and agricultural product safety that might exist in the application process of organic fertilizers were reviewed,and the migration and transformation mechanism and blocking and control technologies of new pollutants in soil were summarized.It also summarized the risk limit indicators related to new pollutants in organic fertilizer product standards worldwide,which provided a reference for improving China's compost and organic fertilizer quality standard system and improving the standardization level of organic fertilizer industry.
