Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

This category of emissions is the largest source of volatile organic compounds (VOCs) produced by automobiles, which are a main source of haze, ozone, and particulate matter. If fuel vapor is released into the atmosphere, it contributes to a category of pollutants known as evaporative emissions.

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.

lower ozone formation potential of the carbonyl compounds present than DF under the identical operating conditions. In addition, there was an 18.0–35.8% reduction in total carbonyls and a 3.4–100% 100% drop in individual carbonyls in the constant load/varying speed test mode. CFT had 16.5–44.1% —Hao et al. 2014.05.025.

systems in areas classified “Serious,” “Severe,” or “Extreme” for nonattainment of the ozone national ambient air quality standard (NAAQS). Gasoline-rich vapors in an empty automobile fuel tank are forced out when liquid gasoline is pumped into the tank. The CAA requires states to implement Stage II gasoline vapor recovery.

Two maps compare total annual sulfur dioxide amounts for India and China during 2005 (left) and 2016 based on Ozone Monitoring Instrument measurements. First, the researchers collected estimated emission amounts from inventories of the number of factories, power plants, automobiles and other contributors to sulfur dioxide emissions.

Volatile organic compounds (VOC), which include hydrocarbons, are major air pollutants as well as precursors of harmful compounds such as tropospheric ozone and secondary organic aerosols. compounds containing 2-12 carbon atoms) are mainly produced by automobiles, a conclusion in line with previous findings.
