Fluvial (n = 11) and lacustrine (n = 4) habitats water samples were collected in the dry and rainy seasons of 2022-2023. Among limnological parameters, the highest mean electrical conductivity values of 6063 mu S/cm were noted in the.IS basin during the rainy season and the lowest was 0.04 mg/L for nitrite in the CS basin. Generally, the levels of organic contaminants and ecological risk indices were as follows: rivers of.IS > rivers of CS > Alibey Dam Lake (.IS) > Atikhisar Dam Lake (CS). The highest non-carcinogenic health risks of 0.88 were noted for children in the CS basin during the dry season and the lowest of <0.01 in Atikhisar Dam Lake during the rainy season. Multivariate statistical techniques were applied to data to categorize investigated ecosystems and sources apportionment of contaminants and geospatial distribution.en10.1016/j.marpolbul.2023.115405info:eu-repo/semantics/openAccessCanakkale Andistanbul StraitsOrganic PollutionEcotoxicological Risk AssessmentGIS Based EvaluationWater-QualityFresh-WaterPollutionStreamBasinArticle194N/AWOS:0010685539000012-s2.0-8516800403637598535Q1
