Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. But volatile chemical products used in common solvents and personal care products are literally designed to evaporate.

Large-scale study finds air pollution increases ER visits for breathing problems; rate depends on age, pollutant and lung disease

Green Car Congress

As levels of ozone and fine particulate pollution (PM 2.5 ) rise, more patients end up in the ER with breathing problems, according to the largest US study of air pollution and respiratory emergency room visits of patients of all ages. In “Age-specific Associations of Ozone and PM 2.5 among children, 5.1% among adults under 65 and 3.3%

The New Supersonic Boom

Cars That Think

Piloting the bullet-shaped Bell X-1 rocket plane in 1947, Chuck Yeager became the first person to exceed the speed of sound while in horizontal flight. But as was true for concerns about the ozone layer back in the 1960s, proponents of supersonic commercial aviation need to consider the deleterious effects of. Everett Collection/Alamy.
