Another important component of emissions is volatile organic compounds (VOCs), a broad classification of carbon-based molecules that are easily vaporized and that can contribute to ozone formation. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g., Resources Samuel J. Cliff, Alastair C.
The US Environmental Protection Agency (EPA) proposed standards to reduce harmful air pollution from oil and gas drilling operations. The VOC reductions in the proposal are expected to help reduce ozone nonattainment problems in many areas where oil and gas production occurs.
The burning of coal releases more carbon dioxide than other fossil fuels, as well as comparatively high levels of other pollutants, including sulfur dioxide, nitrogen oxides, and particles such as ash. This particle effect is a double-edged sword because reducing them is a good thing in terms of lessening air pollution and acid rain.
As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. Similar reactions influence the creation of nitrate aerosols.
For a number of the most important pollutants, levels were substantially lower than required by regulations. They were tested on multiple repeats of these cycles, and measurements of more than 300 regulated and unregulated air pollutants were made in accordance with the highest laboratory standards.
