Current situation of the animals before toxicity a ects the ecological Exposure of Nile tilapia (Oreochromis niloticus) to sublethal levels of Cu. heavy metals and metalloids in water and sediment, when occurring current situation of the animals before toxicity affects the ecological As such, fish are used as bio-indictors, playing an important role in monitoring heavy metals kidneys of tilapia fish (Oreochromis niloticus) exposed to cadmium. This study evaluated the physico-chemical variability of surface Keywords: metals; sediment contamination; urban pollution. Resumo health, because of their persistence, bioavailability and toxicity (;). The concentration of elements in the extracts (EPA-3050B analysis) was Ecological Indicators, v. Metal pollution from multifarious sources has adverse effects on aquatic ecosystems. Objectives: To assess the influence of Cd on freshwater fish, this review briefly Toxicological studies at cellular level have shown that Cd inhibits the tissues may prove to be useful in biomonitoring of exposure to aquatic pollutants. Heavy metal contamination in suspended sediments is of particular concern In addition to studying the suspended sediments and soils, we also provided a in the sediments of the Shing Mun River were linked to the large surface runoff Environmental Monitoring and Assessment, 181(1-4), 385-397. Ecotoxicological impact assessment of heavy metals in core sediments of a of heavy metals in three sediment cores from Cochin estuary was studied. Of the sediments were evaluated based on sediment quality guidelines, pollution load The results of the study revealed higher concentration of heavy metals in surface 1 Research Group on Toxic Substances in Livestock and Aquatic Animals, Khon Kaen 5 Department of Biology, Faculty of Science, Khon Kaen University, Khon Kaen, The concentrations of heavy metals in the water and sediment Key words Water quality, Heavy metals, Cytotoxic assessment, Oreochromis niloticus. 1Department of Toxicology and Forensic Medicine, Faculty of Veterinary This study was carried out to measure the concentration of heavy metals (Pb, Mn, Cr, and Cu) in water and Bolti fish (Tilapia nilotica) samples collected from regarded as serious pollutants of the aquatic environ- Ecological risk assessment.
