IARC (WHO) commented in 1989...It won't matter to CARB. It's too bad they didn't simultaneously perform the same study but with DI gasoline exhaust though, that'd have been interesting...
International Agency for Research on Cancer. 1989. “Diesel and gasoline engine exhausts and some nitroarenes.” IARC. Vol. 46: 88-185, Appendix A-2…Epidemiology studies of carcinogenicity to humans....The Working Group noted that the nonlead particulate concentration [of gasoline engine exhaust] was less than 1/20 the lowest level of particulates that produced an excess of lung tumours in the studies of diesel exhaust. The highest levels of gasoline engine exhaust that can be tested are limited by the toxicity of carbon monoxide....
"Excess"? The implication being that there is some satisfactory number of lung tumors that should be produced?IARC (WHO) said:"....produced an excess of lung tumours..."
Die, most likely.What will we do when the particulate filter usage produces a shortage of lung tumors?
Not "satisfactory", but "normal"."Excess"? The implication being that there is some satisfactory number of lung tumors that should be produced?
