Fluoride is one of the priority chemicals being monitored under the sustainable development goal target for drinking water. Excessive ingestion of fluoride in concentrations higher than 1.5 mg/L may cause dental, skeletal and neurological disorders. The study, therefore, assessed community awareness of dental fluorosis as a health risk associated with fluoride contamination in groundwater sources in Mangochi district. Water samples from 82 water points were tested for fluoride and concentrations between 0.2 and 27.2 mg/L were detected, with a mean value of 3.7 mg/L and a median value of 3.1 mg/L. Nine water points registered fluoride concentrations above 6 mg/L, which is the Malawi standard value for fluoride in boreholes and shallow wells. Prevalence rate for dental fluorosis among children in the study was at 82.7%. However, 100% of the children's parents displayed low or no awareness of dental fluorosis as a health risk associated with fluoride contamination in drinking water. The study recommends the use of solar powered reticulated systems, whose water source shall be from a contamination-free zone, and supply to the affected villages. Human health risk assessment using the US-EPA approach needs to be conducted in the affected villages to understand the extent of exposure to fluoride-related health risks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
