Environmental impactArsenic concentration in rice can be very high compared to other cereals due to the nature of the plant and its growth conditions as well as due to environmental pollution such as the use of arsenic containing pesticides and contaminated irrigation water. This study provides information about total arsenic and arsenic species in rice-based products such as miso, syrup and amazake to better understand their health impact. Consuming such products can provide up to 23% of the Provisional Tolerable Daily Intake of arsenic. This is of concern to certain population who already consume arsenic rich products (rice and seaweed). Similar products from barley or millet, which contain lower levels of inorganic arsenic, can be alternatives until low arsenic containing rice is available.
