Toxicity of Copper and Cadmium to Freshwater Fishes
Two freshwater fishes, Rasbora sumatrana (Cyprinidae) and Poecilia reticulata (guppy) (Poeciliidae) were exposed for a four-day period in the laboratory condition to a range of copper (Cu) and cadmium (Cd) concentrations. Mortality was assessed and median lethal concentrations (LC50) were calculated. LC50 increased with decrease in mean exposure times for both metals. For R. sumatrana, LC50s fo...
متن کاملA Transcriptomic Analysis of Cave, Surface, and Hybrid Isopod Crustaceans of the Species Asellus aquaticus
Cave animals, compared to surface-dwelling relatives, tend to have reduced eyes and pigment, longer appendages, and enhanced mechanosensory structures. Pressing questions include how certain cave-related traits are gained and lost, and if they originate through the same or different genetic programs in independent lineages. An excellent system for exploring these questions is the isopod, Asellu...
متن کاملThe concentration of Lead, Cadmium, Zinc and Copper in sediments of Ganduman wetland with geochemical indices
Sediments play an effective role in pollution control or water purification of the wetland ecosystem and record heavy metals contamination as an historical archive. Ganduman wetland is one of the top 10 birdwatching wetlands in Iran. This study aimed to to investigate the concentration of lead, cadmium, copper and zinc in Ganduman sediments. For this purpose, sediment samples were collected man...
متن کاملHematological changes in Tinca tinca after exposure to lethal and sublethal doses of Mercury, Cadmium and Lead
Tench, Tinca tinca, were exposed to three treatments (one acute lethal 96 hrs Lc50/48 hrs and two chronic sublethal 10 and 25% Lc50/504 hrs) each of Mercury, Cadmium and Lead and its behaviour as an indicator of impaired hematology was studied. It was observed that impairments in hematological parameters (increased/decreased Hct, Hb, RBC, WBC and Lct) were reflected in behaviour of fish in the ...
