The ecological indices of the lake water indicate low contamination degrees by heavy metals. A dermal exposurebased health risk evaluation revealed no carcinogenic or non-carcinogenic impact on human health. The contamination factor (CF) for Cu, Ni, Pb, Mn, Fe, and Zn (CF < 1) indicate low contamination levels, while Cd reaches very high contamination in most sediment sites (CF ranges from 6.2 to 72.4). Furthermore, the potential ecological risk factor (Eri) and modified hazard quotient (mHQ) indicate low ecological risk for all metals except Cd, revealing high to very high-level ecological risk in most sites (Eri ranges from 185 to 2173 and mHQ from 1.8 to 6.3). This emphasizes the urgency of prompt actions to improve the environment in Bitter Lake.eninfo:eu-repo/semantics/closedAccessSpatial DistributionSediment And Water PollutionBitter LakeEcological IndicesHuman Health RiskArticle19237271076WOS:0010157518000012-s2.0-85162223009N/A10.1016/j.marpolbul.2023.115096Q1
