Aromatic - A type of hydrocarbon, such as benzene or toluene, added to gasoline in order to increase octane. Some aromatics are toxic.
Aromatic - a hydrocarbon that consists of one or more benzenoid rings (i. e., benzene)
Asthma - a medical condition characterized by abnormal restriction of breathing, especially in response to allergens or air contaminants ...
Aromatics: A type of hydrocarbon that contains a ring structure, such as benzene and toluene. They can be found for instance in gasoline.
Aromatic Hydrocarbons - Hydrocarbon compounds in which the carbon atoms are connected by a ring structure that is planar and joined by sigma and pie bonds between the carbon atoms. An example of an aromatic compound is benzene, C6H6.
Aromatic
A class of hydrocarbons consisting of cyclic conjugate carbon atoms, such as benzene or toluene, commonly added to gasoline in order to increase octane. Some aromatics are toxic.
Arsenic (Ar) ...
Aromatics: A type of hydrocarbon, such as benzene or toluene, with a specific type of ring structure. Aromatics are sometimes added to gasoline in order to increase octane. Some aromatics are toxic.
Arsenicals: Pesticides containing arsenic.
Aromatic any organic compound containing de-localised electrons in a ring structure - e.g. benzene, benzoic acid.
...
Aromatic A form of bonding in which ring compounds share electrons over more than two atoms. The electrons are delocalized. This leads to unusual ring stability.
...
Aromatic: Of or relating to organic compounds that resemble benzene in chemical behavior. These compounds are unsaturated and characterized by containing at least one 6-carbon benzene ring.
Polycyclic aromatic hydrocarbons (PAHs) are a group of compounds formed during the incomplete combustion of coal, oil, gas, wood, garbage or other organic substances.
Polynuclear Aromatic Hydrocarbons

Polycyclic Aromatic Hydrocarbons (PAHs) are derived from the incomplete combustion of fossil fuels producing asphalt, coal tar and creosote, a wood preservative.
monocyclic aromatic hydrocarbon
Organic compound containing one carbon and one hydrogen and consisting of one ring in the molecular structure.

Polynuclear aromatic hydrocarbons (PAHs or PNAs)
PNAs or Polynuclear Aromatic Hydrocarbons, are natural constituents of crude oil, and also may be formed when organic materials such as coal, oil, fuel, wood or even foods are not completely burned.
Terpenoids Aromatic hydrocarbons formed by many plants and responsible for many of the plant scents. Territoriality The establishment by an animal or animals of an area from which other individuals are partially or totally excluded.
PAHs: Polycyclic Aromatic Hydrocarbons.
Particulate Matter: A state of matter in which solid or liquid substances exist in the form of aggregated molecules or particles. Airborne particulate matter is typically in the size range of 0.
Reformulated Gasoline: Gasoline with a different composition from conventional gasoline (e.g., lower aromatics content) that cuts air pollutants.
Refueling Emissions: Emissions released during vehicle re-fueling.
NMVOC emissions = chemicals other than methane that contain carbon, including alcohols, aldehydes, alkanes, aromatics, halocarbons and ketones
NO = nitric oxide
NO2 = nitrogen dioxide ...
burn "dirty," producing not only hydrocarbons but also tiny soot particles that pollute the air and can aggravate heart and lung problems. Secondly, the grilling of meat can form two kinds of potentially carcinogenic compounds: polycyclic aromatic ...
well studied toxicant whose properties are assumed to apply to an entire chemically and toxicologically related class; for example, benzo(a)pyrene data may be used as toxicologically equivalent to that for all carcinogenic polynuclear aromatic ...
Heavier components of crude oil, such as polynuclear aromatic hydrocarbons (PAHs) appear to cause the most damage; while they are less toxic, they persist in the environment much longer than volatile components.
