Arsenic in Rice: A New Global Disaster

Debasis Chakrabarty


Rice (Oryza sativa L.) is amidst the great essential food crop that offers a staple food for most
of the world’s populace. Arsenic (As) is a carcinogenic heavy metal, which harms human
health. In Asian countries, a major source of human As-intake is rice grains and; contamination
of paddy soils by As and accumulation of As in rice grains is one of the serious agricultural
issues. Hence, it is important to mitigate the effects of As toxicity as much as possible. In
an attempt to minimize As accumulation in grains various genes have been introduced in
rice. The main objective of this review is to provide an overview of the arsenic problem and
various biotechnological methods exploited for reducing As accumulation in rice grain.
