Key Points

This analysis aims to quantify the presence of per- and polyfluoroalkyl substances (PFAS) in dust from e-waste recycling facilities.
Conducted targeted analysis, dTOP assay, and hydrolysis on dust samples.
Evaluated data from two Canadian e-waste recycling facilities.
Assessed potential dust ingestion scenarios for workers.
Detected significant amounts of PFAS precursors in e-waste dust samples.
Estimated high-exposure scenario suggests concerning levels of dust ingestion.
Findings raise health risk concerns for workers handling e-waste.

Abstract

An analysis of PFAS in dust from two Canadian e-waste recycling facilities using targeted analysis, dTOP assay and hydrolysis revealed significant amounts of precursors. Workers estimated dust ingestion under high-exposure scenario raises concerns.
