Biosolids generated during wastewater treatment contain PFAS which are persistent, bioaccumulative and toxic. Application of biosolids to agricultural land may result in soil, groundwater and surface water PFAS contamination via leaching and run-off and pose unknown potential risk to soil health, crops and beneficial biota. This study aims to generate novel knowledge on the PFAS fate in biosolid amended soils, crops and toxicity to key soil and aquatic biota at environmentally relevant concentrations. This study is supported by Australian water and its allied industries, as it is important for them to ensure that biosolids application to agricultural land is an environmentally sustainable solution to the Australian farmers and communities.

废水处理过程中产生的生物固体含有持久性、生物蓄积性和毒性的PFAS。生物固体在农业用地上的应用可能通过淋滤和径流导致土壤、地下水和地表水PFAS污染，并对土壤健康、作物和有益生物群构成未知的潜在风险。本研究旨在对PFAS在生物固体改性土壤、作物中的命运以及在环境相关浓度下对关键土壤和水生生物的毒性产生新的认识。这项研究得到了澳大利亚水务及其相关行业的支持，因为对他们来说，确保生物固体在农业用地上的应用对澳大利亚农民和社区来说是一种环境可持续的解决方案是很重要的。
