EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

Green Car Congress

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

US and UK researchers report direct measurement of key atmospheric reactant; more rapid formation of secondary aerosols

Green Car Congress

succeeded in isolating the simplest CI and reported direct kinetic measurements of its reactions with water, NO, NO 2 , and SO 2. Dr. George Marston from the University of Reading (UK) notes that: The Criegee intermediates (CIs) are central to understanding the reactions of ozone with unsaturated compounds. Welz et al.

EPA Proposes Transport Rule to Cut Pollution from Power Plants in 31 States and DC; New Approach for Pollution Reduction

Green Car Congress

This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines. SO 2 and NO x react in the atmosphere to form fine particle pollution and ground-level ozone (smog), which are linked to widespread illnesses and premature deaths. NO x emissions would drop by 52%.
