چکیده
Alam, M. K. and O. E. Maughan (1992). "THE EFFECT OF MALATHION, DIAZINON, AND VARIOUS CONCENTRATIONS OF ZINC, COPPER, NICKEL, LEAD, IRON, AND MERCURY ON FISH." Biological Trace Element Research 34(3): 225-236. Acute and chronic toxicity tests for malathion, diazinon, copper (Cu), mercury (Hg), lead (Pb), zinc (Zn), nickel (Ni), and iron (Fe) were conducted. Mortalities of Barilius vagra and Cyprinus carpio (common carp) were variable but LC50-96 hr were similar for pesticides, Adult B. vagra seem to be more sensitive to malathion than juvenile carp. Both juvenile carp and adult B. vagra were extremely sensitive to diazinon. Long-term exposure to pesticides modified morphology and behavior. The LC50-96 values for Cu, Hg, and Pb were 0.3, 0.16, and 0.44, respectively, for smaller fish and 1.0, 0.77, and 1.33, respectively, for larger fish. Replicate LC50 values for Zn, Ni, and Fe were somewhat variable, and for these metals, the size of the fish seemed to affect response because LC50 values increased as fish size increased. Cooper, Pb, Zn, and Fe residues following exposure to sublethal concentrations of these metals for 15 d were significantly greater in whole juvenile common carp than in controls.

متن کاملThe effects of climate on Pacific salmon - A Summary of published literature
This is a summary of the published studies of the effects of climate and climate change on Pacific salmon. The summary reports the results of the research in a way that is readable for the general public. Consequently, the standard approach of referencing the various statements to appropriate papers is omitted. Instead, we produced an annotated bibliography of approximately 350 papers that is a...
متن کاملHistopathological effects of acute copper sulphate exposure on kidney, liver and gill of common carp, Cyprinus carpio, fingerlings
In the present study histological effects of copper sulphate on, 180 common carp, Cyprinus carpio, fingerlings were studied. In this regard, fish of treatment groups were exposed to 2, 4, 6, 8 and 10 ppm of copper sulphate during 4 days. Behaviours and clinical signs of fish were recorded during the experiment, and samples were done from kidney, liver and gill of moribund and fresh dead fish, a...
