Seasonal Contrast of Some Anthropic Pollution Parameters in Water Retention in Mountainous Area under Sahelian Climate: Elementary Dynamics and Space Distribution (Territory of the Mounts Mandara, Cameroon)

摘要

In order to understand the origin, the extent andthe space distribution of the seasonal anthropic pollution parameters in thewater retention located in mountainous areathickly populated and which water resources is intended for the production ofdrinking water for serving a population of approximately 800,000 inhabitants,two sampling campaigns were carried out for the two seasons of the year knownas the dry and rainy season. The samples were then conveyed and analyzed inlaboratory. The parameters retained for this study were primarily thephysicochemical parameters (pH, conductivity and temperature), measured in situ and second the major anthropicorigins anions of (,?, and ). The results of the study show that overall theanthropic pollution parameters undergo an important seasonal variation of theirconcentration between the dry and rainy periods although they remain high inany season compared to the quality standards of natural water of the EuropeanUnion. Their space distribution within retention remains overall random and isnot function of the seasons. However, surrounding areas of the retention andthe discharge system of the seasonal rivers (Mayos) which feed it present inrainy season space distributions of concentrations in anions of anthropicorigin enumerated above highest.
