NIOSH investigators conducted site visits at the four airports, collecting general area and personal breathing zone (PBZ) air samples for carbon monoxide (CO), nitrogen dioxide (NO2), nitric oxide (NO), diesel exhaust particulate (measured as elemental carbon [EC]), and volatile organic compounds (VOCs).

Emission control strategies, such as aftertreatment systems, have been implemented to reduce the health hazardous particulate matter (PM) and nitrogen oxides (NOx) emissions. (lu.se)
In fact, when tested for BS-VI norms, compared with petrol, LPG emits nearly half of the carbon monoxide (CO), total hydrocarbons (THC) and nonmethane hydrocarbons (NmHC)," Gupta says. (thehindubusinessline.com)
The test results show enhanced combustion leads to a 20 per cent increase in fuel efficiency, a significant and large decline in toxic hydrocarbons, nitrogen oxides and carbon monoxide, and a minimal 20 per cent decrease in greenhouse gases," Dr Dingle wrote. (theoildrum.com)

The proposed EU and national 2010 targets for sulphur dioxide appear achievable, but reaching those for nitrogen oxide, ammonia and VOC emissions will require substantial further reductions and additional policies and measures in most Member States. (europa.eu)
Control techniques for carbon monoxide, nitrogen oxide, and hydrocarbon emissions from mobile sources. (upenn.edu)
Reduction of nitrogen oxide (NOx) emissions is just one area in which improved fuel injection has a dramatic effect: the enhanced mixing realized from high-pressure fuel injection produces far lower NOx levels for a given fuel consumption. (laserfocusworld.com)
It basically consists of two catalysts in series: a nickel-copper alloy reduction catalyst to control nitrogen oxide emissions, and a platinum-palladium oxidation catalyst to control carbon monoxide and hydrocarbon emissions. (epa.gov)
Unlike burning fossil fuels like mineral diesel - which releases carbon dioxide into the atmosphere which had been buried for millions of years - burning plant material only releases the carbon dioxide that the plant had absorbed in the last few years as it grew, not any new emissions in our lifetime. (thebiglemon.com)
The fuel change also reduced the hydrocarbon and carbon monoxide emissions, particularly from RME. (lu.se)
Pollutants4
It produces a wide range of atmospheric pollutants including short lived climate pollutants (SLCPs), such as black carbon (BC). (wikipedia.org)
Air pollution from burning coal, oil and gas flaring and residues, power stations and nuclear station releases particles of ash, gases such as carbon dioxide and sulphur compounds to the air space as pollutants. (imechanica.org)
The 6 pollutants that complete knowledge about the effects of account for the large majority of air pollum pollutants, uncertainty factors are applied tion worldwide and for which standards are to lower the risk of an effect induced by air usually specified include carbon monoxide pollutants. (who.int)
This unique combination allows ICOS to observe, for example, how much carbon dioxide is taken up or released by the boreal forest and how greenhouse gases and air pollutants are acting over this boreal region. (lu.se)
Including carbon dioxide1
In Sammaltunturi, ICOS measures cover most important greenhouse gases including carbon dioxide (CO2), methane (CH4), carbon monoxide (CO) and nitrous oxide (N2O), which are contributing to the increase in the global temperature of the Earth. (lu.se)
Sulphur dioxide1
The fifth environmental action programme emission reduction targets for 2000 will be achieved for sulphur dioxide, but are unlikely to be met for nitrogen oxides and volatile organic compounds (VOCs). (europa.eu)
The aim of this paper is to analyze the characteristics of the HCCI combustion of hydrogen, carbon monoxide and dimethyl ether (DME) in a single cylinder engine. (sae.org)
A mixture of hydrogen and carbon monoxide with a composition of 67% hydrogen and 33% carbon monoxide called methanol-reformed gas (MRG) was used as the low cetane number fuel and DME as the high cetane number fuel. (sae.org)
The results show that the HCCI combustion of hydrogen, carbon monoxide and dimethyl ether has a high thermal efficiency over a wide operating range. (sae.org)
It produces injury through several mechanisms, including thermal injury to the upper airway, irritation or chemical injury to the airways from soot, asphyxiation, and toxicity from carbon monoxide (CO) and other gases such as cyanide (CN). (medscape.com)
Therefore, it is important to understand what controls this accumulation of carbon and exchange of greenhouse gases in the boreal forest, and what is the forest's potential response to climate change. (lu.se)
Nitrous oxide1
100 ft), the elevated partial pressure of nitrogen can exert an anesthetic-like effect similar to that of nitrous oxide. (msdmanuals.com)
Pollution1
All the trends are upward except for coal, but in terms of fossil fuel burning, the switch is often from coal o natural gas - this reduces pollution as methane burns more cleanly than coal, BUT, it is still contributing to rising carbon dioxide levels! (docbrown.info)
Black carbon1
The United Nations has raised concerns about the amount of black carbon and methane produced from open burning as a method of waste disposal. (wikipedia.org)
Continuous1
If you operate a Class I municipal waste combustion unit , also install, calibrate, maintain, and operate a continuous emission monitoring system for nitrogen oxides. (cornell.edu)
Fuel1
While the actual properties of acetone-seeded nitrogen are significantly different from those of natural gas, research on fuel injection into open air with various gas mixtures indicates that little variation (due to gas properties) is exhibited via the injection on plume penetration speed, jet shape, and dispersion. (laserfocusworld.com)
However, cyanosis is an unreliable indicator of hypoxia because neither carbon monoxide nor CN cause cyanosis. (medscape.com)
Dioxide levels2
Hypoventilation can increase blood carbon dioxide levels and cause shortness of breath and sedation. (msdmanuals.com)
thus, arterial blood gas (ABG) testing after a dive typically does not detect any increase in carbon dioxide levels. (msdmanuals.com)

Gas ranges , which may produce nitrogen oxide, a respiratory irritant, are used for cooking in more than half of the homes in the United States [Belanger and Triche 2008]. (cdc.gov)
Waste1
Additionally, if you operate a Class I municipal waste combustion unit , you must also monitor the oxygen (or carbon dioxide) concentration at the location where you monitor nitrogen oxides. (cornell.edu)
Emission1
Advanced analyzing techniques were used to characterize the composition of the organic PM. Special attention was paid to an operating point at 18% intake oxygen level with constant engine operating conditions where the emission level of nitrogen oxides (NOx) was low, and carbon monoxide (CO) and total hydrocarbon (THC) were relatively low.

Nitrogen narcosis can be prevented by using helium (instead of nitrogen, as in standard compressed air) to dilute oxygen for deep diving because helium lacks the narcotic properties of nitrogen. (msdmanuals.com)

Carbon dioxide is essential for photosynthesis, which is why it's good to plant as many trees and garden plants as you can to help reduce this most abundant greenhouse gas. (blackgold.bz)
Engine1
Carbon monoxide can enter a diver's air supply if the air compressor intake valve is placed too close to engine exhaust or if the lubricating oil in a malfunctioning compressor becomes hot enough to partially combust (flashing), producing carbon monoxide. (msdmanuals.com)
In this post we'll just consider the simplest case, direct warming, where the only input is the change in carbon dioxide level, and there are no feedbacks. (joannenova.com.au)
