UB study finds link between ambient ozone exposure, artery wall thickness

Green Car Congress

Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. The study found that chronic exposure to ozone was associated with a progression of thickening of the main artery that supplies blood to the head and neck.

In-cylinder pressure (on the left) and heat release rate (on the right) as a function of the CAD and ozone concentration injected in the intake of the engine for PRF40. The results show that ozone seeding improves combustion and advances phasing. Ozone was produced with an ozone generator. Credit: ACS, Masurier et al.

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.

UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said. Full implementation of these measures would reduce future global warming by 0.5 °C

GM Spring Hill to run on 100% solar power by 2022

Green Car Congress

General Motors expects its Spring Hill Manufacturing plant will be powered by 100% solar energy beginning in late 2022. A green tariff agreement with the Tennessee Valley Authority is expected to supply up to 100 megawatts of solar energy per year, or the amount of electricity consumed by 18,000 United States households annually.
