To assess health risks from nitrate and fluoride in groundwater across multiple Nigerian states.
Analyzed 623 groundwater samples from 10 Nigerian states
Examined fluoride and nitrate levels using standard procedures
Evaluated health risks via oral and dermal exposure pathways
Fluoride levels exceeded safe limits in most samples, ranging from 1.25 to 8.47 mg/L
Nitrate levels were generally safe, except in some Delta communities where they exceeded 50 mg/L
Fluoride ingestion showed significant non-cancer risks for all age groups
Cancer risk for nitrate exceeded the USEPA threshold across all age groups, especially in Delta State hotspots
