spirulina platensis, a cyanobacterium of economic important was studied for the tolerance to cadmium. the bioassay studies showed the ec50 value to be 1.53 mg/g. the cyanobacterium was very sensitive to low metal concentration and the productivity was also reduced. the chlorophyll pigments reduced with decreasing the algal biomass. the algal survival rate showed a marked reduction in their surv...

abstract in respect to nano-technological studies and physiological and biochemical lesions of these materials on aquatic animals, in this study we examine the toxicity effects of nano-zinc oxide (zno nps) on hematological indices of common carp (cyprinus carpio). lc50 of nano zinc oxide was determined according to the mortality at 24, 48, 72 and 96 hours, respectively. during separate experime...

background: paraquat is a non-selective contact herbicide, widely used to control weeds in agriculture farms and aquatic plants in surface waters. paraquat can have adverse effects on the health of aquatic organisms. the aim of this study was to detect the alterations in the blood biochemical parameters of common carp exposed to sub-lethal concentrations of commercial formulations of paraquat. ...

diazinon is commonly used for pest control in the agricultural fields surrounding freshwater reservoirs. this study was conducted to determine the chronic toxicity of organophosphorous pesticide and its effects on some hematological parameters and biochemical blood plasma profiles of common carp, cyprinus carpio. diazinon was applied at concentrations of 60 and 120î¼g/l preparations in 10, 20 a...

Freshwater cat fish Clarias batrachus was exposed to Butachlor, Imidacloprid and Sodium fluoride with lethal and sub-lethal concentration for 72 hrs and 21 days durations. Protein changes in liver and muscles were analyzed after exposure period. Imidacloprid and sodium fluoride caused remarkable protein loss lethal concentration but at sub-lethal level their toxicity was moderate. But Butachlor...

The effect of biopesticide - Derisom on certain metabolites and enzymes of carbohydrate metabolism were evaluated in gill, liver, kidney and muscle of Cyprinus carpio during sub-lethal toxicity exposure of 21 days. A dose of 0.28 ppm was taken as the sub-lethal dose. The organs were taken from exposed and control fish at the end of 24 hrs, 7, 14 and 21 days and used for the estimation of total ...

Paraquat can have adverse effects on the health of aquatic organisms. The aim of this study was to detect the alterations in the blood biochemical parameters of common carp exposed to sub-lethal concentrations of commercial formulations of paraquat. ...

the purpose of this study was to examine the acute and sub-acute effects of diazinon onhistopathological parameters of liver tissue and blood level of hepatic enzymes of male commonfrog (rana ridibunda). frogs were assigned to 9 groups (n=8, meaning 8 frogs in each group):control and treatment groups with 30, 60, 90 and 120 μg/l diazinon in water for one day or oneweek. hepatic enzymes containi...
