Aldehydes
Aldehydes

An aldehyde /ˈældɪhaɪd/ or alkanal is an organic compound containing a functional group with the structure −CHO, consisting of a carbonyl center with the carbon atom also bonded to hydrogen and to an R group, which is any generic alkyl or side chain. The group—without R—is the aldehyde group, also known as the formyl group. Aldehydes are common in organic chemistry. Many fragrances are aldehydes.

Oxides of Nitrogen (NOx, NO) NO

This webpage provides a brief description of nitrogen oxide (NOx) emissions and general information about the air quality programs in New England that focus on reducing NOx. Nitrogen Oxides are a family of poisonous, highly reactive gases. These gases form when fuel is burned at high temperatures.

Particulate Matter
Particulate Matter

Particulate matter (PM) is a mixture of particles that can adversely effect human health, damage materials and form atmospheric haze that degrades visibility. PM is usually divided up into different classes based on size, ranging from total suspended matter (TSP) to PM-10 (particles less than 10 microns in aerodynamic diameter) to PM-2.5 (particles less than 2.5 microns).

Peroxyacyl Nitrates
Peroxyacyl Nitrates

Peroxyacyl nitrates (also known as Acyl peroxy nitrates, APN or PANs) are powerful respiratory and eye irritants present in photochemical smog.

Sulfur Oxides (SOx) SO2 - Sulfur Dioxide
Sulfur Oxides (SOx) SO2 - Sulfur Dioxide

EPA’s national ambient air quality standards for SO 2 are designed to protect against exposure to the entire group of sulfur oxides (SO x). SO 2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SO x).

Tropospheric Ozone
Tropospheric Ozone

Tropospheric ozone is a greenhouse gas and initiates the chemical removal of methane and other hydrocarbons from the atmosphere. Thus, its concentration affects how long these compounds remain in the air.

Volatile Organic Compounds
Volatile Organic Compounds

VOCs mean volatile organic compounds and are found in a wide variety of products such as solvent-based paints, printing inks, many consumer products, organic solvents and petroleum products. M otor vehicles and vessels also emit VOCs that eventually cause air pollution and smog.
