Quantitative evaluation of surface water pollution by antibiotic residues in Yaounde of Cameroon

Many studies have been undertaken in order to find pollutants of anthropic origin found in surface waters. Recently discovered we reported the emergence of water pollution by drugs. Although present at little concentrations, the water pollution by antibiotics can be at the origin of health and environmental risks which must not be neglected. In order to quantitate their presence in domestic and hospital waste, two molecules of antibiotics: Ciprofloxacin (CIPX) and Ceftriaxone (CFX) have been the subject of this study. The three STEP sampling being: STEP of the CNPS hospital, STEP of “camp Sic Messa”, STEP of “camp Sic Cite Verte”. We obtained from chromatographic analyses quantify CPX contents of 7.329 µg/L at the entry of the “camp SIC Messa”. The CIPX was observed in all the sites of sampling with contents of 46.103 µg/L at the entry of the STEP of the CNPS hospital, of 9.835 µg/L downstream from the Ebogo River, of 15.490 µg/L downstream of the Abiergué River and of 2.459µg/L at the entry of the STEP of the “camp Sic Cite Verte”. These results show a persistence of antibiotic molecules in the environment.
