recently, some natural products have been used in the fields as alternative to synthetic compounds, to minimize the negative impacts to the environment. this study aimed to verify the effects of neem-based bio-pesticide in causing acute toxicity for a fish and chronic toxicity for a microcrustacean. to this end, danio rerio and daphnia magna were exposed to various concentrations of a neem-base...

Randomly selected 320 fingerling of Labeo rohita were collected from Faheem fish farm, Mattital Road, Multan. Groups of 40 fish each were exposed to subleathal concentration of imidacloprid (120 mg L-1) under short (2, 4 and 8 days) and long term (16, 32 and 64 days) conditions to access the effect of this most extensively used pesticide on the body composition parameters of economically most i...

The freshwater fish, Cyprinus carpio, exposed to acute exposure period (Lethal concentration for 96 hours = 4.369 ppm) and 1⁄2 and 1/4 th sub lethal concentrations (2.185 and 1.092 ppm) of chemathoate for 30 days. The protein content various tissues of fish was observed after exposure period. Acute exposure caused a significant decrease the protein content in testis, ovary and brain and insigni...

chemical pollutants presence in water may induce severe ecological consequences and consequently affecting aquatic ecosystems integrity. heavy metals are dangerous pollutants for aquatic inhabitants that have a great stability. heavy metals contamination (pollution) of the surface waters happens widely by discharge of mill effluents. the objective of the present study was to determine the 50% l...

Background: Diazinon is an organophosphorous pesticide which widely found in municipal, agricultural, and urban storm water discharges. The present study was conducted to achieve lethal concentration (LC50) and behavioral changes of Rutilus rutilus caspius and Hypophthal-micthys molitrix after exposure to lethal concentration of diazinon. Methods: The experiment was carried out in static con...
