Given that Catalytic converters have been about for some 30 years could it be that the claimed rise of heavy metals soil traces may be attributed to them. I have often wondered.

The researchers found high concentrations of platinum, palladium, rhodium and osmium in air over the Boston metropolitan area. Although these particles — known as platinum group elements — are not yet considered a serious health risk, evidence suggests they potentially could pose a future danger as worldwide car sales increase from an estimated 50 million in 2000 to more than 140 million in 2050
