“…Moreover, the correlation between U-tAs and U-F- is strong (r s = 0.633, p < 0.001). Another common source of iAs and F − exposure is diet, including foods rich in iAs (e.g., rice, fruits, fruit juices or food cooked iAs contaminated water) [ 35 , 36 ] and tea, maize, cereals, juices and sodas prepared with high F − water, which are known to contain substantial amounts of F − [ 37 , 38 ].
