别自己粉了就以为别人都粉。说话要有证据，别妖言惑众。你在下面声称NOx是一级致癌物？看看美国政府CDC网页说什么：

How likely are nitrogen oxides to cause cancer?

The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have not classified nitrogen oxides for potential carcinogenicity.

你先传谣言，说欧洲政府不限定NOx排放。被揭穿了就接着谣言NOx致癌，现在怎么说？

自己掌嘴吧。
