摘要：The sources of mercury in hospital wastewaters include potable water supply, medical equipment breakage, laboratory chemicals, medicinal wastes, amalgam from dental clinics, human amalgam and dietary waste retained in wastewater sumps and traps. Cleaning products used in hospitals may contain trace mercury levels from the caustic soda used in production of soap or from chemicals that may contain traces of mercury as an impurity. This Study assesses the mercury content in hospital waste water from the hospital in Jhansi City. Samples were collected from three different sites during different season and were analyzed quantitatively. The quantity of mercury ranged between 0.100 mg/L to 0.150 mg/L. the higher conc. is found in waste water samples collected from site C which is the disposal site of laboratory, radiology department, operation theatre etc. These finding are higher than agreeable limit of EPA which is 0.002 mg/L. This indicates the contamination of receiving environment due to discharge of mercury in hospital waste water which could harm human and aquatic life. In this study in methods were used for reduction of mercury in hospital waste water. The sulfide precipitation reduced the quantity of mercury from 0.210 mg/L to 0.006 mg/L. By using charcoal, it was found that mercury was reduced from 0.210 mg/L to 0.003 mg/L.
