Introduction: The environmental effects of the mining industry, include potential contaminants that affect soil, water and foodstuffs. Drinking water is the main route of manganese (Mn) to humans and, vegetables are an important human food, with increasing consumption in rural communities.

Objective: The aim of this study was to measure Mn-concentration in soil, drinking water and vegetables (edible part of lettuce, (Lactuca sativa)), in the rural village of Huechún, Chile, the inhabitants of which live near a mine tailings dam.

Materials and Methods: Atomic absorption spectrometry (AAS) was used to quantify Mn in soil, drinking water and lettuce. The analyses revealed the presence of Mn in all analyzed samples, with concentrations below the thresholds established by national and international regulations.

Results: Mn-concentrations in drinking water according with sampling period exceeded the safe level recommended by the U.S. EPA and European Union (50 µg L-1) but were insufficient to severely impair in intellectual functions in children mainly.

Conclusion: Based on the results of this report, we believe that the Mn intake of the inhabitants of Huechún may not pose a health risk.
