Abstract

Rice is known to accumulate methylmercury (MeHg) in the rice grains. MeHg as a neurotoxin impacts on the human central nervous systems and especially on the developing brain. In this exploratory study, 87 commercial rice products sold in Europe, including nine baby-rice products, were analyzed for total Hg and MeHg content. MeHg concentration in all rice products investigated range from 0.11 to 6.45 μg kg-1 with an average value of 1.91 ± 1.07 μg kg-1 and baby-rice is not significantly different from other rice products. Total Hg ranges from 0.53 to 11.1 μg kg-1 with an average of 3.04 ± 2.07 μg kg-1. MeHg concentrations in all rice products studied in this work would not exceed the provisional tolerable weekly intake (PTWI). 30 % of all commercial market rice products exceeded 10% of the PTWI calculated for toddlers or 13 % of products for adults with rice based diet.
