متن کاملReproductive health indicators of immature common carp exposed to municipal wastewater of Behbahan, Iran
Exogenous estrogens or pollutants with estrogen-like activity can induce vitellogenin (VTG) synthesis in male and juvenile fish, making this protein a useful indicator of chemicals that mimic estrogenic activity. The purpose of this study was to investigate the impact of municipal wastewater on blood biochemical parameters of common carp (Cyprinus carpio). Under experimental conditions, biomark...
متن کاملEmerging Pollutants in Aquatic Environment: Source, Effect, and Challenges in Biomonitoring and Bioremediation- A Review
Emerging contaminants are distributed in to the environment from various anthropogenic activities. These Emerging contaminants (ECs) are mainly composed of products, such as pharmaceuticals, personal care products (PCPs), surfactants, plasticizers, pesticides etc. The present conventional system of waste treatment are not designed to treat these contaminants. Complex structure of these pollutan...

متن کاملEffects of agro-chemicals on fishes: With reference to changes in circulating biochemical parameters in Clarias gariepinus induced with Paraquat dichloride
The response of Clarias gariepinus to Paraquat dichloride, a herbicide that is in high demand in the fragile Niger Delta ecological zone was investigated. The herbicide had been detected in most of the water bodies in the region. The fishes were exposed to the range of concentrations observed in the field (0, 2, 4, 6 and 8) µg/L for 28 days, conducted under the Organization for Economic Co-oper...
