Environmental Effect of Lead Contamination on Mining Communities in Zamfara State, Nigeria: A Review

The proliferation in recent time of unregulated artisanal gold mining activities in Zamfara State, Nigeria has fuelled instability and lead poisoning crisis across gold mining communities primarily in Anka and Bukkuyum Local Government Areas thereby placing a significant burden on the already fragile economy and heath care system in the state [1]. The act of manual grinding into fine particles and processing of gold found in lead-rich ore resulted in extensive dispersal into space of lead dust, causing massive environmental contamination from the lead deposits in villages and compounds where the gold ore are being processed. In March, 2010, Medecin Sans Frontieres (MSF) (Doctors without borders) discovered an unprecedented epidemic of lead poisoning in the State. An estimated 400 to 500 children were reported to have died as a result of lead absorption [2]. A team of experts comprising members from the CDC

The center for disease control (CDC) has been instrumental in the environmental health investigation and emergency response. The CDC as of 2016 estimates that there were over 40 additional contaminated villages affecting more than 30,000 residents. The situation is such that the prevailing environmental and health emergency cannot be resolved quickly. It requires remediation alongside medical treatments and persuading people to adopt new practices and behaviors. WHO and multiple partners have positioned that, resolving the Zamfara lead poisoning disaster requires coordinated and integrated medical intervention, environmental remediation and establishment of safer mining and processing methods [1,3]. Consequently, there is the need for long term engagement on the part of leaders and authorities at community, state and federal levels in the country. This will also require the engagement of health and environment professionals, technical partners and donors
