Assessment of Trace element based health risk in fruits at rural areas in Bangladesh

Abstract

Abstract Metal pollution is influenced to accumulation of trace metals in fruits which have adverse effect on human health such as cancer and non cancer diseases. This study was investigated the accumulation of arsenic and manganese in fruits through irrigation water or soil and its associated health risk for adults and children. It was conducted in May to November, 2018 at Samta village of Jashore district in Bangladesh. Concentration of arsenic and manganese was measured by HG-AAS and flame-AAS methods respectively. Daily intake of metals, pollution index and its health risk index was calculated by using USEPA method. Concentration range of arsenic and manganese in fruits was measured 0.096 ± 0.001mg/Kg to 0.533 ± 0.005mg/Kg and 0.561 ± 0.001mg/Kg to 12.834 ± 0.015mg/Kg. Maximum concentration of arsenic and manganese was detected in papaya and guava fruits due to accumulate high concentration of arsenic and manganese from irrigation water and soil. Total hazard quotient data range for adults and child was not exceed than 1 which is indicated that fruits are safe from non carcinogenic health risk from arsenic and manganese. On the other hand carcinogenic risk of arsenic for adults and child data ranges were 1.68×10+ 00 to 3.05×10− 01 and 1.00×10+ 00 to 1.81×10− 01 which was higher than the carcinogenic cancer risk value 1.00×10− 6.In addition it is concluded that fruits were not safe from carcinogenic health risk by arsenic at this study area which has a strong correlation with arsenic contamination in irrigation water and soil. This study will be updated the information on arsenic and manganese contamination in fruits and its health safety.
