Abstract
- Total mercury levels and methylmercury levels were investigated for various grain parts (whole rice, rice husk, brown rice, polished rice, and bran) of 507 rice samples from 15 main rice-producing areas of China. The average total mercury contents in brown rice samples and polished rice samples were 4.2 and 3.3 μg/kg, respectively, the percentages exceeding the national standard limit were 0.59% and 0.39%, respectively. The average methylmercury levels were 2.9 and 2.4 μg/kg in brown rice and polished rice, respectively. The order of total mercury contents in different parts of rice was bran > brown rice > whole rice > rice husk > polished rice, and the order for methylmercury was bran > brown rice > whole rice > polished rice > rice husk. Total mercury intakes and methylmercury intakes were estimated for the Chinese population and the associated health risks were assessed. [ABSTRACT FROM AUTHOR]
