Arsenic-polluted water is turning rice into a toxic staple, especially in Asian countries, researchers have warned. The semi-metal, a natural component of the Earth’s crust, is commonly found in soil and groundwater – especially in south and southeast Asia. But it is extremely harmful if consumed, and arsenic contamination has been linked to serious health conditions including cancers, skin lesions and diabetes.While drinking water is heavily regulated and monitored by governments including the UK, researchers estimate that roughly 32 per cent of the world’s population live in countries which do not adhere to the safe limits set by the World Health Organization. Figures on actual exposure remain more limited, but the WHO estimates that up to 220 million people regularly drink groundwater with high levels of arsenic contamination.Dr Manoj Menon, an environmental scientist at the University of Sheffield’s Institute for Sustainable Food, warned that this a particularly significant issue for regions heavily reliant on rice. "Rice is a semi-aquatic plant – usually grown in standing water on the soil, it [is] vulnerable to picking up arsenic from the water around it," he said. "If the water is contaminated with arsenic, it goes into the plant."The Scale of the ProblemThe same is true of cooking rice. If arsenic-safe water is used, it removes it from the staple – but if the water is contaminated, rice just absorbs more of the semi-metal. But many countries in Asia – including Bangladesh, China, Thailand and Cambodia – still use outdated measures to determine if water is ‘safe’, according to a study in Science of the Total Environment, which builds on research on arsenic-spiked water over the last 20 years."The arsenic problem is affecting millions worldwide, particularly in Asian countries," said Dr Menon, lead author of the report. "We already know that rice has more arsenic than other cereals, and the risk is exacerbated if we cook rice with arsenic-contaminated water above the WHO recommended limit."Health Implications and Strategies"That is why it is vitally important that countries worldwide work to adopt the latest WHO recommendations to ensure arsenic exposure is minimised as much as possible to protect the public," he said. "People in the UK may only consume around 5kg of rice annually, but the average global consumption is 57kg, and even higher at 85kg across Asia."Prof Andrew Meharg, a professor of plant and soil sciences at Queen’s University Belfast who was not involved in this study, said the outlook in West Bengal, Bangladesh and the poorer delta regions of southeast Asia "is pretty bleak". "[Their] water source is contaminated; their primary food source, rice, is contaminated. The only way to deal with the water issue is to both invest in very large-scale treatment plants to clean up either groundwater or to make river water microbially safe, and pipe this water to people’s homes," he told the Telegraph.Future DirectionsIn the latest study, Dr Menon’s team compared arsenic absorption across different types of rice, with different contamination rates, and while using different cooking methods. They found white and parboiled rice, which are most commonly eaten in the West and across Asia, absorb more arsenic than brown rice when cooked with contaminated water.Dr Menon said that finding and rolling out better ways to reduce arsenic-contamination in rice is critical, given the health ramifications. For instance in Bangladesh, it emerged in the late 1990s that thousands of wells were contaminated after millions of people became sick.Acute arsenic poisoning has dramatic and immediate effects, including vomiting, abdominal pain, diarrhoea and – in extreme cases – muscle cramping and death. But numerous studies have also linked long-term exposure to various cancers, cardiovascular disease and diabetes. According to the WHO, early childhood exposure can also have a negative impact on cognitive development, and increased deaths in young adults.There are some strategies to reduce the risk. In Bangladesh – where people consume an average of 170kg of rice annually – authorities now paint wells red or green, after testing them for arsenic. But the problem persists, and researchers are now focusing on strategies to reduce the amount of arsenic that rice absorbs. For More Interesting News Follow Us on Instagram){kind=link}
Researchers warn that contamination is a big situation for areas closely reliant on the semi-aquatic crop. Arsenic-polluted water is popping rice right into a poisonous staple, particularly in Asian nations, researchers have warned. The semi-metal, a pure part of the Earth’s crust, is usually present in soil and groundwater – particularly in south and southeast Asia. However this can be very dangerous if consumed, and arsenic contamination has been linked to critical well being circumstances together with cancers, pores and skin lesions and diabetes.
Whereas ingesting water is closely regulated and monitored by governments together with the UK, researchers estimate that roughly 32 per cent of the world’s inhabitants stay in nations which don’t adhere to the secure limits set by the World Well being Group. Figures on precise publicity stay extra restricted, however the WHO estimates that as much as 220 million individuals repeatedly drink groundwater with excessive ranges of arsenic contamination.
Dr Manoj Menon, an environmental scientist on the College of Sheffield’s Institute for Sustainable Meals, warned that this a very important situation for areas closely reliant on rice. “Rice is a semi-aquatic plant – often grown in standing water on the soil, it [is] weak to choosing up arsenic from the water round it,” he mentioned. “If the water is contaminated with arsenic, it goes into the plant.”
The Scale of the Drawback
The identical is true of cooking rice. If arsenic-safe water is used, it removes it from the staple – but when the water is contaminated, rice simply absorbs extra of the semi-metal. However many nations in Asia – together with Bangladesh, China, Thailand and Cambodia – nonetheless use outdated measures to find out if water is ‘secure’, in keeping with a examine in Science of the Whole Setting, which builds on analysis on arsenic-spiked water during the last 20 years.
“The arsenic downside is affecting hundreds of thousands worldwide, notably in Asian nations,” mentioned Dr Menon, lead creator of the report. “We already know that rice has extra arsenic than different cereals, and the chance is exacerbated if we cook dinner rice with arsenic-contaminated water above the WHO really useful restrict.”
Well being Implications and Methods
“That’s the reason it’s vitally necessary that nations worldwide work to undertake the newest WHO suggestions to make sure arsenic publicity is minimised as a lot as attainable to guard the general public,” he mentioned. “Folks within the UK might solely devour round 5kg of rice yearly, however the common world consumption is 57kg, and even increased at 85kg throughout Asia.”
Prof Andrew Meharg, a professor of plant and soil sciences at Queen’s College Belfast who was not concerned on this examine, mentioned the outlook in West Bengal, Bangladesh and the poorer delta areas of southeast Asia “is fairly bleak”. “[Their] water supply is contaminated; their major meals supply, rice, is contaminated. The one approach to cope with the water situation is to each put money into very large-scale therapy crops to wash up both groundwater or to make river water microbially secure, and pipe this water to individuals’s properties,” he advised the Telegraph.
Future Instructions
Within the newest examine, Dr Menon’s staff in contrast arsenic absorption throughout various kinds of rice, with completely different contamination charges, and whereas utilizing completely different cooking strategies. They discovered white and parboiled rice, that are mostly eaten within the West and throughout Asia, take in extra arsenic than brown rice when cooked with contaminated water.
Dr Menon mentioned that discovering and rolling out higher methods to scale back arsenic-contamination in rice is essential, given the well being ramifications. For example in Bangladesh, it emerged within the late Nineteen Nineties that 1000’s of wells had been contaminated after hundreds of thousands of individuals turned sick.
Acute arsenic poisoning has dramatic and instant results, together with vomiting, stomach ache, diarrhoea and – in excessive instances – muscle cramping and dying. However quite a few research have additionally linked long-term publicity to numerous cancers, heart problems and diabetes. In line with the WHO, early childhood publicity can even have a unfavourable affect on cognitive growth, and elevated deaths in younger adults.
There are some methods to scale back the chance. In Bangladesh – the place individuals devour a mean of 170kg of rice yearly – authorities now paint wells pink or inexperienced, after testing them for arsenic. However the issue persists, and researchers are actually specializing in methods to scale back the quantity of arsenic that rice absorbs.
