Fariha Latif* and Muhammad Javed
.... 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 three fish species (120-day old) towards metals mixture was measured in term of 96 h LC50 and lethal concentration. These acute toxicity tests were performed at constant temperature (30o

...tify the process of MeHg bioaccumulation in vivo on the species of rotifers Brachionus plicatilis. We analysed the relationship between the ratio of photoluminescence (PL) intensities (I585/I480) and MeHg concentration (CMeHg) to create a master curve for calculating MeHg concentration based on the measurement of PL intensities. Quantitative results showed that the bioaccumulation of MeHg in the rotifers increased from 1.65 ...
