...identify exposure to oil contaminants. L. carinatus was chronically exposed to crude oil at intervals of 24 hours, 15 days and 30 days. The LC50 of crude oil for L. carinatus was 700 ppm. HPLC analysis of 16 polycyclic aromatic hydrocarbons (PAHs) in the flesh demonstrated that PAHs accumulation in the treated snails was fluctuated with time. The accumulation is due to their biotransformation process during metabolism. The histopathological observations of the...

Fish from different species has diverse ecological needs and respond differently to the environmental stress conditions. Thus, the sensitivity, bioaccumulation and antioxidant capacities of three major carps Catla catla, Labeo rohita and Cirrhina mrigala towards metals mixture (Cd+Cr+Cu+Pb) were determined during present research work. Sensitivity of the thr...

Therefore, this experiment was planned to assess the acute affect of lead (Pb+2) on peroxidase (POD) activity in tissues viz. liver, gills, kidney, muscle, heart and brain of fish Catla catla exposed for 4-day. After each sampling (24-hr interval) fish were dissected and required org...

The goal of this study was to look at the students’ knowledge, attitudes, and practices on food safety and cleanliness at a different institution in KPK, Pakistan. A cross-sectional study was done among 1000 government and private university students in KPK, Pakistan, using a self-administered, pre-tested questi...

Here, we have investigated the toxic effects of four pesticides, namely, chlorantraniliprole, penoxsulam, pymetrozine, and haloxyfop-P-methyl, on the survival and growth of the larvae of two anuran species, Fejervarya limnocharis and Microhyla fissipes. Our results showed that s...

The MN frequencies of all the pesticide treated mussel groups increased significantly (p< 0.05) until the end of the exposure period as compare to control. The highest MN frequencies were recorded after cypermethrin exposure on day 12 (7, 8.5 and 11‰ for 0.5 ppm, 1 ppm and 1.5 ppm concentrations respectively) in haemolym...
