Based on national NOX emission data compiled by the U.S. Environmental Protection Agency [46], on- and off-road vehicle emissions comprised 53% of NOX emissions during 1998 as opposed to electrical generation (25%) and industrial combustion (12%).
In contrast, the summed degradation emissions in Peru were 11% but the timber harvest emissions comprised 8% of total degradation.
The measurements of gaseous emissions comprised carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), total organic carbons (TOC), nitrogen oxides (NOx), polycyclic aromatic hydrocarbons (PAH), and 33 volatile organic compounds (VOC).
No, because the Porter Ranch plume is comprised of "fugitive emissions", which are "unintentional and could not reasonably pass through a stack, chimney, vent, or other functionally-equivalent opening," according to the California Air Resources Board (CARB), which oversees the state's cap-and-trade system.
Between 2000 and 2007, industrial ecosystem emissions comprised from 1% to 7% of net system production.
All acquisitions were carried out in 2D mode, the protocol comprising an emission scan with 5 min per bed position.
Though his third and final term is set to end in 2014, Mayor Bloomberg wants one-third of the city's taxi fleet to be comprised of zero-emissions vehicles by 2020.
However, studies not meeting the criteria for regulated emissions were considered if they comprised measurements of non-regulated emissions (aldehydes, ketones, aromatic compounds, PAH, nPAH), investigations in humans, data of animal experiments, or in vitro assays of biological effects.
The photoluminescence spectra of these ZnO films showed a strong near band-edge ultraviolet emission together with deep level emission bands comprised of green and orange-red luminescence.
Preindustrial δ34S signatures in Greenland ice cores were comprised of marine biogenic emissions, continental dust sources, background volcanism, and continental biota [7].
