Example text

The top two, which contain iron chips and sand, are for removing the arsenic and have holes in the bottom; the bottom pitcher collects the filtered water. 11 A variation on this system, called the Sono filter, was developed by Dr Abul Hussam, a chemistry professor at George Mason University in the United States. In 2007 he won the US National Academy of Engineering’s Grainger Challenge Prize for low-cost ways of removing arsenic from water. Hussam expected companies to want to commercialise the product, but this did not happen, so he spent the $1 million prize on building a manufacturing facility and lab in his native Bangladesh.

Representatives of the government of West Bengal and many scientists took part, including some from the British Geological Survey (which, in 1992, had been designated by the WHO to be its international collaboration centre on groundwater). Also present were twenty patients from affected villages (18 of whom are now dead, 15 of them from various types of cancer). 11 A team from the Dhaka Community Hospital visited Chakraborti in July 1996 to learn more about the problem in the Bengal region after their discovery of a number of patients in Bangladesh showing symptoms of arsenic poisoning.

This information acted as a stimulus for further testing and led to the discovery of arsenic contamination in the river basins of Nepal, Myanmar, Cambodia, Vietnam and Pakistan. China also discovered severe problems in Inner Mongolia and Shanxi province. Since 2000 there have been discoveries of arsenic contamination in water in other countries, but there are large parts of the world where testing capacity is limited and so information is scarce. 11 Changes in the WHO standard reflect the growing awareness of the risk posed by arsenic.
