stream water - Opis:
- Nigeria has abundant surface and ground water resources many of which are polluted and can be detrimental to human health when consumed. This study investigated the effects of effluents discharged by industries into streams on the health of people who depend on stream water for domestic purposes in the Onitsha urban area of eastern Nigeria. Water samples collected from eleven discharge locations underwent physico-chemical and microbiological analyses. Data on the effects of industrial effluents on health were obtained from records in the public hospitals located in Onitsha as well as through questionnaire surveys and field observations. The results of the analyses revealed that the effluents grossly degrade surface water bodies; several parameters (temperature, iron, dissolved oxygen, turbidity, biological oxygen demand, chemical oxygen demand, lead, magnesium, total heterotrophic counts, total coliform group, pH) had values which were higher than the WHO (2011) safety limits for drinking water. The contamination of investigated streams by effluents had negative impact on the health of stream users. The discussion included health effects of polluted water and the prevalence of water borne or related diseases in the area. Implications of these findings were also discussed. Management measures capable of minimizing contamination of surface water in the study area were suggested.
