چکیده    The aim of our work was to evaluate the physicochemical and bacteriological risks as well as the concentration of the heavy metals on the liquid effluents of some services of the hospital hassan ii in fez. the analyses were performed according to the international standards for wastewater discharge recommended by world health organization 1989 (who). the results showed that these effluents were very loaded with pollutants and constitute a threat to the environment and to the health. indeed,the concentrations for cod and bod5,respectively,in 100% and 75% of the samples were very high and do not comply with the who standards as well as for conductivity in 58%,nitrates in 66%,ammonium and the suspended solids in 100% of the samples. while other physicochemical parameters such as ph,temperature and nitrites do not exceed current standards. from a bacteriological point of view,the presence of pathogenic germs was demonstrated,such as fecal coliforms,staphylococcus,fecal streptococci and clostridium at all the studied sampling sites,while the germ of salmonella was absent. the analysis results of the heavy metals comply with the wastewater discharge standards recommended by who. the results of this work showed that,the effluents from the hassan ii hospital in fez require a pretreatment before evacuation in the communal sanitation sewers. © university of mohammed 1er oujda morocco.
