abstract={Donaten¡¯s Ecological and Biological Important Area is subject to anthropogenic pressure; resulting in its pollution. This study has enabled the assessment of pollution of its maritime part with a view to its preservation. Thus, physico-chemical parameters such as color, temperature, pH, dissolved oxygen, oxygen saturation, salinity, TDS were recorded <i>in situ</i> in three different points on the coast, two of which showed evidence potential pollution. Water samples were taken in these points for determination of BOD<SUB>5</SUB> and COD, concentration of suspended solids, ammoniacal nitrogen, total nitrogen, nitrates, orthophosphate, total phosphorus, copper, zinc, lead and cadmium using standard methods. The results of physico-chemical characteristics recorded, namely temperature (29.8¡ãC to 30.1¡ãC), suspended solids (1.41 to 42.3 mg/L), pH (6.4 to 6.9), dissolved oxygen concentration (5.4 mg/L to 6.2 mg/L), oxygen saturation (80 to 94), salinity (29.8 to 32.1 g/L), TDS (29513 to 31533 mg/L), COD (&lt;5 to 26 mg/L), BOD (&lt; 1 to 18 mg/L), ammoniacal nitrogen (&lt;0.05 to 2.89 mg/L), nitrates (0.27 to 0.32 mg/L), total kjedahl nitrogen (3.8 and 7.1 mg/L), ortho phosphate (0.002 to 0.47 mg/L), total phosphorus (0.73 to 2.2 mg/L), copper (0.01 to 1.13 mg/L), zinc (1.53 to 2.41 mg/L), lead (&lt;0.001 at 0.022 mg/L) and cadmium (0.008 to 0.012 mg/L) revealed that Donaten¡¯s Ecological and Biological Important Area was not polluted with organic and metallic trace elements pollutants. This study could form a basis for further scientific studies.},
