Project description:To assess the impact of surface water across the Hun River, several sampling sites located in the mainstream and the tributary were selected representative of pollution gradient and different pollution source. Male adult zebrafish were exposed to surface water from seven sites for 4 days. The obiectives of the study was to evaluate the ability of transcriptomic profiles exposed to surface water to determine the potential biological effects, to differentiate different pollution source, and to identify the toxic components.

Project description:Female Atlantic cod (Gadus morhua)were devided in to five groups and oraly exposed to alkylphenols and produced water for 20 weeks. Differentially expressed genes were studied in liver samples using the CodStress array. The five groups were fed with feed-paste containing two different doses of the AP mixture (Low AP and High AP), PW, 17?-estradiol (E2) and toxicant-free paste (control group) respectively. The body burden for each compound corresponded to 20 ?g/kg of total AP in Low AP group, 4000 ?g/kg ?g/kg of total AP in High AP group, 100 ?g E2/kg in the E2 group 500 mg PW/kg in the PW group.
