Review of Drinking Water Quality in Nigeria: Towards Attaining the Sustainable Development Goal Six

Abstract

Access to potable water is a major problem confronting most developing nations particularly with the overwhelming health burden posed by polluted water and its sources. In this review, studies on the level of contamination of drinking water sources in different geopolitical zones in Nigeria were assessed. The anthropogenic activities eliciting the pollutions were extensively discussed. Overall, the level of Nigeria preparedness in meeting the sustainable development goal number 6 (SDG no 6: to ensure availability and sustainable management of water and sanitation for all) was evaluated. Cogent methods that could enhance the achievement of SDG no. 6 were suggested. From our analysis of published literature, pre- and post- SDG implementation in Nigeria, it is clear that no significant progress has been made in providing potable water for all in Nigeria. All implementing partners must therefore rejig the process to ensure the availability of potable water, in order to achieve the sustainable development goal six.

Evaluation of Heavy Metals in Auto Mechanics in Aba Metropolis, South East, Nigeria Who Were Exposed to Petrol and Petroleum Products

“…In the control subjects, the order from the highest concentration was; Cr > Pb >As > Cd > Hg. The reason for this high chromium concentration in the control group might be adduced to a poor source of drinking water and some agricultural products consumed within the mechanic workshops [16,[25][26][27] even if we know that automechanics are expose to radiator repairs, welding, spray painting, and automobile battery recycling among others which could have increase the chromium levels. On the other hand, these workers are exposed to various toxic chemicals including lead (Pb) and polycyclic aromatic hydrocarbons [28] which could be absorbed into the body through direct skin contact, ingestion, or inhalation.…”
