Professor Andy Meharg

Professor in School of Biological Sciences

Institute for Global Food Security (IGFS), School of Biological Sciences

Professor Meharg has gained a worldwide reputation for his research into a global food problem – the high levels of toxic arsenic in rice, the staple diet of half the world’s population.

Professor Meharg's research into arsenic in rice has led to new regulations from the EU and the World Health Organisation (WHO), setting guidance standards. People are recognising the problem, the dangers of disease such as lung and bladder cancer.

He and his team have come up with one answer which has been described as a breakthrough – developing a rice cooker that works like a coffee percolator.

A Queen’s graduate, Professor Meharg began his academic career in chemistry, focusing on plants and soils. He was interested in thinking about more fundamental environmental issues, and has used chemistry in this direction.

He and his team are now looking at how pollutants move through agronomic food chains, how they get into soils, how they’re transferred into plants, and the human exposure to that. All analysis is based on high end analytical chemistry.
