Air Pollution and Stratospheric Ozone Depletion
| Term | Definition |
|---|---|
| air pollution | the introduction of chemicals, particulate matter, or microorganisms into the atmosphere at concentrations high enough to harm plants, animals, and materials such as buildings, or to alter ecosystems |
| asbestos | a long, thin, fibrous silicate mineral with insulating properties which can cause cancer when inhaled |
| brown smog | smog that is dominated by oxidants such as ozone; also known as photochemical smog |
| gray smog | smog dominated by sulfur dioxide and sulfate compounds; also known as sulfurous smog |
| haze | reduced visibility |
| industrial smog | smog dominated by sulfur dioxide and sulfate compounds; also known as sulfurous smog |
| inversion layer | the layer of warm air that traps emissions in a thermal inversion |
| London-type smog | smog dominated by sulfur dioxide and sulfate compounds; also known as sulfurous smog |
| Los Angeles-type smog | smog that is dominated by oxidants such as ozone; also known as photochemical smog |
| ozone (O3) | a secondary pollutant made up of three oxygen atoms bound together |
| particles | solid or liquid particulars suspended in air; also known as particulate matter, particulates |
| particulate matter (PM) | solid or liquid particulars suspended in air; also known as particulates, particles |
| particulates | solid or liquid particulars suspended in air; also known as particles, particulate matter |
| photochemical oxidant | a class of air pollutants formed as a result of sunlight acting on compounds such as nitrogen oxides |
| photochemical smog | smog that is dominated by oxidants such as ozone; also known as Los Angeles-type smog, brown smog |
| primary pollutant | a polluting compound that comes directly out of a smokestack, exhaust pipe, or natural emission source |
| secondary pollutant | a primary pollutant that has undergone transformation in the presence of sunlight, water, oxygen, or other compounds |
| sick building syndrome | a buildup of toxic pollutants in an airtight space, seen in newer buildings |
| smog | a type of air pollution that is a mixture of oxidants and particulate matter |
| sulfurous smog | smog dominated by sulfur dioxide and sulfate compounds; also known as London-type smog, gray smog, industrial smog |
| thermal inversion | a situation in which a relatively warm layer of air at mid-altitude covers a layer of cold, dense air below |
| volatile organic compound (VOC) | an organic compound that evaporates at typical atmospheric temperatures |
