Scientists at the Massachusetts Institute of Technology have detected for the first time the presence in the atmosphere of toxic metals from automobile catalytic converters.
The study conducted by Swedish researchers in collaboration with MIT and the Woods Hole Oceanographic Institution has revealed high concentrations of platinum, palladium, rhodium, and osmium in the ambient air of Boston. Although concentrations of pollutants are not considered to be dangerous for health today, the problem is for the future. It is estimated that more than 140 millions of new vehicles equipped with catalytic converters will be on sale in 2050. (Ecology note: he was not supposed to have no more oil in 2050?)
According to Sebastien Rauch of the Chalmers University of Technology in Gothenburg, the priority now is to find ways to stabilize these particles in catalytic converters. The results of this study will be published on December 15
in Environmental Science and Technology.
