Hydrochemical characteristics and metallic quality in fish in the Loukkos river estuary of Morocco
The region of Larache endures a big problem of pollution of the surface waters. This pollution takes various origins, domestic, agricultural and industrial. The study of the physicochemical characteristics (Water temperature, pH, Salinity, DO, Conductivity, SM, TOC, NO3, COD and BOD) of the effluent...

The region of Larache endures a big problem of pollution of the surface waters. This pollution takes various origins, domestic, agricultural and industrial. The study of the physicochemical characteristics (Water temperature, pH, Salinity, DO, Conductivity, SM, TOC, NO3, COD and BOD) of the effluents exits of the industrial units of the Loukkos river estuary shows, that these units are responsible of important organic discharges and heavy metals. Indeed, the wastewaters used to drain rice fields are at the origin of important organic discharges which drag strong concentrations in SM and NO3, also most effluents present a strong salinity (conductivity) and TOC concentration. This high level of pollutants concentration can be a main cause of poisoning for the receiving environment. They especially conjugate themselves by the waters qualities deteriorate of the Loukkos river estuary downstream.
