Arsenic  In The Food Chain  - An International Threat
Calling it a ‘global problem’, researchers have expressed their fears over arsenic poisoning, especially in developing countries.

The scientists, speaking at the Royal Geographical Society (RGS) annual meeting in London, warned that about 140 million people, mainly from the south and east of Asia were in danger of arsenic poisoning, primarily from their drinking water. The hazards are none less than cancer, they add.

This is not all. The scientists also warn that consuming large amounts of rice grown in such affected areas could also be a health risk. "It's a global problem, present in 70 countries, probably more," Peter Ravenscroft, a research associate in geography with Cambridge University informs. "If you work on drinking water standards used in Europe and North America, then you see that about 140 million people around the world are above those levels and at risk."

What are the risks of consuming higher than permitted quantities of arsenic? According to experts, arsenic consumption can bring about higher rates of some cancers, including tumors of the lung, bladder and skin, and other lung conditions. Some of these effects can be visible only decades after the first exposure.

“In the long term, one in every 10 people with high concentrations of arsenic in their water will die from it," observes Allan Smith from the University of California at Berkeley. "This is the highest known increase in mortality from any environmental exposure”. Smith adds that he is yet to see one government agency, which has, gives this problem the priority it deserves.
