Abstract
"Determination of Arsenic in Minor Cereals (Barley, Foxtail Millet, Proso-Millet, Finger- Millet, Pearl -Millet, Buckwheat, Oat, Quinoa and Sorghum) in Gazipur, Bangladesh"
Highlights
Cereals are a staple food for many people around the world including Bangladesh; they are a major dietary source of toxic arsenic (As)
Ensuring safe food is one of the objectives of sustainable development goal-2 (SDG-2). With this view in mind, the Plant Breeding Division of BARI currently working with nine minor kinds of cereal included Barley, Foxtail millet, Proso-millet, Finger-millet, Pearl-millet, Buckwheat, Oat, Quinoa, and BARI-Sorghum 1 were undertaken for biochemical analysis of arsenic on their leaves
The acceptable limit of arsenic in the terrestrial plant was determined less than 10 mg kg-1 under normal conditions (Matschullat, 2000)
Summary
Cereals are a staple food for many people around the world including Bangladesh; they are a major dietary source of toxic arsenic (As). Arsenic has two forms such as trivalent (ASIII) and pentavalent (AsV), it has larger atomic radius, more electron clouds, relative higher reaction affinity (ASIII) to thiol group/sulfhydryl group (-SH) groups than other divalent cations Most and Papenbrock [2]. As such this notorious heavy metal being efficiently absorbed in skin, lung, kidney, liver, and bladder than any other heavy metals. The level of arsenic in the existing cereals has to be determined as a starting point towards lower arsenic variety development. The primary arsenic status of these cereals may have given clues for designing the appropriate breeding program in the future
