Get Arsenic & Rice PDF

By Andrew A. Meharg

Rice is the staple nutrition for half the world’s inhabitants. intake of rice is the key publicity direction globally to the category one, non-threshold carcinogen inorganic arsenic. This booklet explains the resources of arsenic to paddy soils and the biogeochemical tactics and plant physiological attributes of paddy soil-rice ecosystems that bring about excessive concentrations of arsenic in rice grain. It provides the worldwide development of arsenic focus and speciation in rice, discusses human exposures to inorganic arsenic from rice and the ensuing future health dangers. It additionally highlights specific populations that experience the top rice consumptions, which come with Southern and South East Asians, weaning infants, gluten intolerance victims and people eating rice milk. The booklet additionally provides the knowledge of arsenic focus and speciation in different significant plants and descriptions methods for reducing arsenic in rice grain and within the human nutrition via agronomic management.

4 The Effects of Cooking Rice on Its Arsenic Content Another variable that must be considered when determining rice exposure is cooking. Arsenic content of rice can either be increased, decreased or unchanged dependent on the method of rice cooking and the arsenic concentration of the cooking water. Of major concern is in regions of the world that suffer from elevated arsenic in household water supplies, such as Bangladesh and West Bengal, where there is already elevated arsenic in drinking water, rice cooking is a major contributory route to inorganic arsenic ingestion.

3 Considering Rice as an Arsenic Source in Epidemiological Studies Inorganic arsenic, as indeed DMA, has been somewhat ignored when considering food and drinking water exposures. Argos et al. (2010) completed a detailed monitoring of inorganic arsenic ingestion from drinking water in Bangladeshis over 9 years, and used this information along with health outcomes, to predict disease dose responses. Because they ignored rice as a dietary source of inorganic arsenic, the assumptions they made regarding inorganic arsenic intakes and disease outcomes are inappropriate.

It is clear for the Bengal Delta population that rice is a dominant source of inorganic arsenic exposure where water arsenic levels are low, and that the intake levels are elevated enough to constitute notable lifetime excess cancer risks. 38 3 Risk from Arsenic in Rice Grain Another West Bengal study looked at contribution of food composites for adult meals consisting of 750 g of rice per day across low (3 mg/L), intermediate (30 mg/L) and high (120 mg/L) arsenic in drinking water supply (Uchino et al.
