Daily intake of manganese by local population around Kylleng Pyndengsohiong Mawthabah (Domiasiat), Meghalaya in India.

Present work is carried out adjacent to world's highest rainfall area Kylleng Pyndengsohiong (KP) Mawthabah (Domiasiat), Meghalaya in India to establish the baseline value of manganese intake through dietary route by the local tribe population in view of proposed uranium mining. The locally available food items collected from villages surrounding the proposed uranium mining site at KP Mawthabah (Domiasiat) were analysed using Energy Dispersive X-Ray Fluorescence (EDXRF) Technique. The manganese concentration in different food categories varies from 2.76-12.50 mg kg(-1) in cereals, 1.8-4.20 mg kg(-1) in leafy vegetables, 0.30-13.50 mg kg(-1) in non leafy vegetables, 0.50-15.30 mg kg(-1) in roots and tubers, 0.70-1.50 mg kg(-1) in fruits and 0.12-0.96 mg kg(-1) in flesh food. The mean dietary intake of Mn was found to be 3.83+/-0.25 mg d(-1) compared to Recommended Dietary Allowances (RDAs) of 2-5 mg d(-1). The daily intake of Manganese by the local tribe population is comparable with the value (3.7 mg d(-1)) recommended by International Commission on Radiological Protection (ICRP) for reference man and lower than the intake value observed for Indian and other Asian population.
