CATALYTIC converters, meant to clean up car exhausts, are polluting the environment. A group of Italian and French researchers have found traces of heavy metals emitted from the devices in remote regions of Greenland. Seth Dunn of the Worldwatch Institute, a non-governmental organisation based in Washington DC, USA, says, “They have broken new ground.” He says. “The implications could be significant for public health.” Workers involved in refining platinum, one of the metals used in catalytic converters, are known to suffer a higher than usual incidence of asthma.
