Per- and polyfluoroalkyl substances (PFAS), as emerging bioaccumulative contaminants, are widely present in water wastewater systems. Municipal effluents serve pathways for PFAS to enter aquatic environments. This study monitors the treatment lagoons, nearby wetlands bay a Canadian Arctic community. Eight out of 40 targeted were detected samples collected from raw wastewater, natural wetlands, Ungava bay. The total concentrations ranges 45.9-56.1 ng/L 36.6-70.8 measured at 7.3 most prevalent frequently 6:2 FTS, PFHxA, PFNA. At all sites, short-chain surpassed long-chain PFAS. Short-chain peaked 267.01 (79.74%), while totaled 67.83 (20.26%). estimated yearly mass flow rate into environment through lagoon effluent was 2.33 g/year. conducted environmental risk assessment both lagoons three downstream suggests that risks associated with under posed minimal ecological risk, though long-term evaluation is needed. In conclusion, findings this research provide further information on pollution regions may, such, guide development comprehensive regulations safeguard human health environment, thereby mitigating potential future risks.
