This study evaluated the concentrations, sources, and health risks of trace metals metalloids in effluents 15 wastewater treatment plants (WWTPs) located along Black Sea Marmara, ecologically economically vital regions Türkiye. Effluent samples were collected winter autumn, metal concentrations analyzed using ICP-MS to assess seasonal variations potential risks. Results showed notable regional differences, with aluminium (Al) nickel (Ni) as most abundant metals. The highest total concentration was recorded autumn at station S2 (326.09 mg/L). Non-carcinogenic negligible (HI< 1) across all stations, but low carcinogenic (10 -6 < CRi ≤ 10 -4 ) for chromium (Cr) detected some locations. Source apportionment Principal Component Analysis revealed mixed geogenic anthropogenic origins, primarily from industrial activities urban runoff. While generally complied national standards, several exceeded international limits, highlighting ecosystems human health. These findings underscore urgent need stricter discharge regulations, improved technologies, continuous monitoring mitigate environmental impacts WWTP discharges.

The presence of heavy metal(loid)s in sewage sludge is a cause concern and an obstacle to its agricultural valorisation. This study analysed the elemental composition from 42 Portuguese wastewater treatment plants (WWTPs) during summer winter, investigating metal(loid) contamination, nutrient content, potential risks related application soils. Levels 8 were investigated, ranging not detected (Hg) 5120 mg kg-1 dw (Zn), decreasing order Zn > Cu Cr Ni Pb As>Cd Hg. legal requirements for use overall met, but elevated levels Cu, linked industrial sources, exceeded permitted limits 3 WWTPs. On average, N, P, K, Mg, Ca comprised 80 % profile. No seasonal variations found, varied with WWTP size, origin, between thickened digested samples. Environmental hazard indicators showed significant contamination Zn, Cd. However, geoaccumulation index, ecological risk indicators, characterization ratios no sludge-amended soils, assuming single 5 tons ha-1. Human health assessment workers handling identified dermal contact as main route exposure, non-carcinogenic carcinogenic at highest reported levels. Sewage produced Portugal was considered suitable use, provided that it closely monitored well-managed meet needs crops receiving while mitigating environmental risks.
