Biocontamination in Metal Traces (Pb, Cd) of Waters, Sediments and Fish from Urban and Periurban Marine Perimeters in the Community of Lokossa in Benin

In Benin, market gardening has become a new profession and plays an important role in the supply of fresh vegetables. coastal regions, fish farming is practiced on outskirts sites. However, poorly regulated cultivation practices increasing pollution do not necessarily guarantee sanitary quality products delivered. This study aims to evaluate physico-chemical qualities water used for watering and, secondly, lead cadmium contamination watering, soil (sediment) (fish) urban perimeter commune Lokossa Benin. These various samples taken this purpose were analysed at Ministry Health’s Water Food Quality Control Laboratory. We noted organic elements through parameters measured such as temperature, NTK, COD, BOD total phosphorus confirmed by average levels 0.42 mg/L water, 0.52 sediment 0.31 0.76 tissue (Carp Catfish) 0.07 0.1 0.5 cadmium. rates are well above normal values accepted GESAMP, PNEC INERIS FAO standards. The consequences health risks consumers.
