摘要

对全氟烷基和多氟烷基物质(PFAS)潜在健康和环境影响的关注正在以惊人的速度增长,因为预计微量接触会对健康产生不利影响。需要采取极端措施来减轻潜在的PFAS污染并尽量减少暴露。PFAS的广泛使用导致各种PFAS从家庭、工业和城市污水中释放到废水中,在二级处理过程中分解成生物固体。在城市污水处理过程中产生的生物固体是PFAS的主要环境来源,因为普遍的处理做法是作为肥料。热解是一种可行的、可扩展的技术,可用于从生物固体中去除PFAS,同时保留营养物质并产生可再生的能源原料。尽管热解在去除PFAS方面取得了早期的成功,但对于热解产物和排放中的PFAS及其转化产物的命运仍然存在重大的未知因素。适用的PFAS取样方法、分析工作流程和去除评估目前仅限于高兴趣分析物和矩阵的子集。此外,由于成本和采样限制,废气、颗粒物、飞灰和其他热解最终产物的分析在很大程度上没有报道或受到限制。本文确定了生物固体热解的关键知识空白,必须解决这些空白,以评估热解处理过程中PFAS去除的有效性。

Burning questions: Current practices and critical gaps in evaluating removal of per- and polyfluoroalkyl substances (PFAS) during pyrolysis treatments of biosolids

Concerns surrounding potential health and environmental impacts of per- and polyfluoroalkyl substances (PFAS) are growing at tremendous rates because adverse health impacts are expected with trace-level exposures. Extreme measures are required to mitigate potential PFAS contamination and minimize exposures. Extensive PFAS use results in the release of diverse PFAS species from domestic, industrial, and municipal effluents to wastewater, which partition to biosolids throughout secondary treatment. Biosolids generated during municipal wastewater treatment are a major environmental source of PFAS due to prevailing disposal practices as fertilizers. Pyrolysis is emerging as a viable, scalable technology for PFAS removal from biosolids while retaining nutrients and generating renewable, raw materials for energy generation. Despite early successes of pyrolysis in PFAS removal, significant unknowns remain about PFAS and transformation product fates in pyrolysis products and emissions. Applicable PFAS sampling methods, analytical workflows, and removal assessments are currently limited to a subset of high-interest analytes and matrices. Further, analysis of exhaust gases, particulate matter, fly ashes, and other pyrolysis end-products remain largely unreported or limited due to cost and sampling limitations. This paper identifies critical knowledge gaps on the pyrolysis of biosolids that must be addressed to assess the effectiveness of PFAS removal during pyrolysis treatment.
