Bioaccumulation kinetics and organ distribution of lead in a fresh water teleost,colisa fasciatus

The study of bioconcentration, kinetics of accumulation and tissue distribution of lead, in a teleost fish, Colisa fasciatus was undertaken in a laboratory ecosystem. The system was exposed to test water with sublethal concentrations of lead. Variability of lead in tissue (gills, liver, muscles) was evaluated and is presented here. Measurements of lead contained in individual organs expound high concentrations of lead in gills and muscles, explicating gills and muscles as major sites for concentration. The uptake rate kinetics show an initial rapid phase and later slow phase responsible for net accumulation.
