Urban CO2 Domes May Enhance May Increase Ozone and PM, With Accompanying Increase in Mortality

Green Car Congress

In a new study published online 10 March in the ACS journal Environmental Science and Technology , however, Stanford University professor Mark Jacobson finds that local CO 2 emissions in isolation may increase local ozone and particulate matter. Although the health impacts of such changes are uncertain, he notes, they are of concern.

F, with about 40% due to ozone. The second study found that local CO 2 emissions produce CO 2 domes over cities, which increase local ozone and PM, increasing local mortality. The study found that CO 2 domes increase air pollution deaths by 50-100 per year in California, with most occurring in Los Angeles.

Berkeley study identifies diesel as main source of vehicular secondary organic aerosols

Green Car Congress

Organic aerosol (OA) in the atmosphere is detrimental to human health and represents a highly uncertain forcing of climate change. The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone.
