Biosolids following wastewater treatment are a significant source of microplastics (MPs) that are contaminants of concern. MPs in biosolids pose potential unknown risks to agriculture, food security and ecosystem health through their application to farmlands. Currently, the lack of knowledge on the MPs contamination of agricultural soils is a significant knowledge gap. This project aims to generate new knowledge of MPs' fate, behaviour, risk and associated contaminants in biosolids and sludge-amended agricultural soils. The new knowledge generated in this project is expected to help devise better management options to minimise the MP associated risks in agricultural soils, thereby safeguarding the food security and soil health.

废水处理后的生物固体是微塑料 (MP) 的重要来源，而微塑料是令人关注的污染物。生物固体中的 MP 通过应用于农田对农业、粮食安全和生态系统健康构成潜在的未知风险。目前，缺乏对 MPs 对农业土壤污染的了解，这是一个重大的知识差距。该项目旨在产生关于国会议员的命运、行为、风险以及生物固体和污泥改良农业土壤中相关污染物的新知识。该项目产生的新知识预计将有助于设计更好的管理方案，以尽量减少农业土壤中与 MP 相关的风险，从而保障粮食安全和土壤健康。
