This study aimed to determine toxic element concentrations in aquatic environments, including water and sediment, and in the fish, and to evaluate chromosome abnormalities, serum liver enzyme changes and liver histopathological alterations in from the Nam Kok River near the Sepon gold-copper mine, Lao People's Democratic Republic, as compared with a control area without mining activity. The results revealed significant differences ( < 0.05) in As, Ba, Cu, Fe, Mn, Ni, Se and Zn in water, in all of the studied potentially toxic elements in sediment, and in As, Ba, Cd, Cr, Cu, Mn, Ni, Se, and Zn in the fish between the study and control areas.
