The findings of a study by researchers at Carnegie Mellon University, with colleagues at UC Berkeley, suggest that changing atmospheric NO x levels over the next two decades will likely significantly reduce the effectiveness of stricter new gasoline vehicle emissions standards in reducing concentrations of secondary organic aerosol (SOA).

It has not yet been determined in what level the new compounds might be present, and no health standards now exist for them. The compounds were identified in laboratory experiments that mimic the type of conditions which might be found from the combustion and exhaust in cars and trucks, or the grilling of meat over a flame.
