ABSTRACT: This study investigated the groundwater quality and
health risks associated with informal e-waste processing in the Alaba
International Market in Lagos, Nigeria. Twenty-two groundwater samples were
collected from hand-dug wells in the
market area and analyzed for physicochemical properties and heavy metal concentrations. The results showed that the
groundwater quality was poor, with
high levels of heavy metals, including cadmium, lead, and chromium. The
health index (HI) for children and adults was above the tolerable threshold levels, indicating a
potential health risk to the population. Principal component analysis and hierarchical cluster analysis were used to identify
the sources of metals in groundwater,
and the results showed that informal e-waste processing was a significant source of contamination. The study
highlights the need for effective management strategies to mitigate the
potential health risks associated with
informal e-waste processing and ensure public health and environmental
safety.
