Surface sediments in Çamlıgöze Dam Lake show low contamination and limited ecological risk, with deterministic THI of 9.58 × 10 -2 (adults) and 8.81 × 10 -1 (children).
- Why it matters: After a 2021 upstream mining-related leakage, it was unclear whether downstream sediments in northeastern Türkiye carry coherent geochemical evidence of ongoing mining inputs and whether sediment-bound PTEs pose ecological or health concerns.
- What they did: In 2024, surface sediments from eight stations were collected across four seasons and analyzed by ICP-MS after microwave digestion; contamination/ecological indices and PCA plus APCS-MLR were used for source attribution, alongside deterministic risk and Monte Carlo simulations.
- The result: Indices indicated low contamination and limited ecological risk, PCA explained 85.19% of variance, APCS-MLR pointed mainly to lithogenic sources for Fe, Co, and Al, and Monte Carlo modeling supported acceptable carcinogenic and non-carcinogenic risks under upper-bound exposure.
