This is a news article, not a scientific paper so it lacks crucial details. It mentions that materials from catalytic converters have been detected. Does this mean that modern techniques can now detect trace amounts of these materials that have always been there because detection limits have been improved. Or has the concentration of these materials increased to where they are now detectable? Or is this just spin to fuek the enviro-wacko's goal of eliminating the personal automobile?
I'm still waiting for someone to question why airbags were allowed to turn the front seats of our cars into death machines for children and adults under a certain height and weight. Catalytic converters will have to wait in line.
