In the rush to introduce profitable new consumer products, our world has been inundated with chemical species that can spread and contaminate our environment. This proposal addresses the urgent need to study the migration of perfluorinated compounds (PFCs) -- a class of contaminants of "emerging concern" -- in soil. Significant gaps in current knowledge of these contaminants include their occurrence, transport, and transformation mechanisms. This lack of understanding is worrying due to the persistence, adverse health effects and ecological risks of PFCs. PFCs are used as stain repellents and incorporated in a multitude of consumer and industrial products, the majority of which ultimately end up in landfills. Biosolids from wastewater treatment plants also contain PFCs.

在匆忙推出有利可图的新消费品的过程中，我们的世界已经被化学物质所淹没，这些化学物质会传播和污染我们的环境。该提案解决了研究全氟化合物（pfc）——一类“新出现的令人关切的”污染物——在土壤中的迁移的迫切需要。目前对这些污染物的认识存在重大差距，包括它们的发生、运输和转化机制。由于全氟化合物的持久性、不利的健康影响和生态风险，这种认识的缺乏令人担忧。全氟化合物被用作防污剂，并被纳入众多消费品和工业产品中，其中大部分最终被填埋。来自污水处理厂的生物固体也含有全氟化合物。
