- Abstract
The objective of this study is to assess the effluent treatment system produced by hospitals in the coastal department in Benin, in particular the two major centers, namely the National Hospital and University Center - Hubert Koutoukou Maga (CNHU -HKM) and the University Hospital Center of Mother and Child (CHU-MEL). Analyzes focused mainly on the metallic trace elements. The results showed that the treatment of effluents is not effective in places and that their discharges into surface waters can constitute a source of pollution. The COD and BOD values do not meet the quality standards for wastewater discharge in the Republic of Benin. Trace elements, arsenic and fluoride ions meet the standards for discharge of waste water at the outlet. However, the pollution recorded by this study is very damaging to the receiving environment. From all of the above, the system is ineffective and deserves to be strengthened in order to limit the toxic and infectious risks. The construction of efficient treatment and purification stations in all the University Hospitals of the Littoral department by the authorities is necessary and very urgent in order to reduce the health and environmental risks of these hospital effluents.
