STRONG coffee and plenty of it may reduce the risk of heavy-metal poisoning
in cities where drinking water contains high levels of these contaminants. An
international team of scientists has found that while coffee is filtering, the
coffee grounds mop up as much as 90 per cent of the copper and lead dissolved in
the water.
Many cities in the developing world have high levels of toxic metals as
soluble metal ions in their drinking water. Copper and lead enter the water as
it runs through pipes and storage tanks or makes contact with lead solder.
