Linking Vegetable Per- and Polyfluoroalkyl Substance Accumulation with Root Chemical Traits.

ABSTRACT: Per- and polyfluoroalkyl substances (PFASs) are ubiquitous, persistent organic pollutants increasingly detected in food crops, yet their accumulation capacities and regulatory factors across various plant species remain poorly resolved. Here, we investigated the bioaccumulation patterns of PFAS in 20 vegetable species and their relations with root chemical traits in farmland irrigated with treated wastewater. Leafy vegetables (e.g., Lactuca sativa and Spinacia oleracea) accumulated substantially higher PFAS concentrations (mean: 9.24 ng/g) than the root vegetable Daucus carota, with the short-chain perfluorobutanoic acid (PFBA) identified as the dominant species for all vegetables. PFBA showed the strongest mobility and tended to accumulate in edible aerial tissues of
