The act of passing into the atmosphere an air contaminant or gas stream which contains an air contaminant, or the air contaminant so passed into the atmosphere.
The release or discharge of a substance into the environment; generally refers to the release of waste products (Solids, liquids, or gases) into the air, water, or soil.
The process by which surface bound particulate matter enters the atmosphere as a suspension. This expression may however be used more loosely (and incorrectly) to refer to airborne dust.
The discharge of contaminants into the air.
creation of a photon by atomic electron de--excitation.
materials released into the air, water or ground
the release of light from a chromogenic or fluorescent molecule, when an electron falls from an excited state to a lower energy state of the molecule.
The release of any gas, particle, or vapor into the environment from a commercial, industrial, or residential source including smokestacks, chimneys, and motor vehicles.
a substance that is emitted or released
the release of electrons from parent atoms
any of several bodily processes by which substances go out of the body; "the discharge of pus"
the discharge of gases or particles, such as from a smokestack or automobile engine.
The release of a substance from a point or diffuse source into the atmosphere.
discharge of a pollutant from some source into the environment.
A material which is expelled or released to the environment. Usually applied to gaseous or odorous releases to atmosphere. End-Use
Compare? The release or discharge of a substance into the environment. Generally refers to the release of gases or particulates into the air.
Release or discharge of any substances (usually effluents or pollutants) into the environment.
A release of combustion gases and aerosols into the atmosphere.
Substances (usually pollutants) discharge into the air.
Refers to gases and other materials vented to the atmosphere by the exhaust system.
A discharge if pollutants into the atmosphere, usually as a result of burning or the operation of internal combustion engines.
The release of impurities
A substance(s) or pollutant emitted as a result of a process.
Anything given off as a result of a process. For example, gases, heat and odours.
Waste substances discharged into the air.
The release from electronic equipment of electromagnetic waves that have the potential to create EMI.
substance that is released or discharged, usually into the air; emit (verb).
The release of radioactivity from a radioactive source.
Release of a quantity of substance, energy or vibration, into the environment (air, water, soil, ...); the emission can be expressed as a total quantity in absolute or as a rate per a defined period of time. IPPC definition: direct or indirect of substances, vibration, heat or noise form individual or diffuse sources in the installation into the air, water or land EPER definition: direct release of a pollutant to air or water as well as the indirect release by transfer to an off-site wastewater treatment plan
Air pollution discharge into the atmosphere, usually specified by mass per unit time.
Pollution discharge from a source.
A substance—usually a gas—which is created as a by-product of a physical process and released to the atmosphere (e.g. carbon monoxide is an emission from a carâ€(tm)s engine).
The release or discharge of substance into the environment. Generally refers to the release of polluants (particulates, NOx, etc.) into the air.
The release of light at a different color (wavelength) indicating the presence of a specific fluorescent molecule (picoseconds after excitation). Time resolved emissions are longer (microseconds) allowing the background emission from other fluorescent molecule to decay prior to reading. This allows greater sensitivities.
Passage of air contaminants into the atmosphere via a gas steam or other means.
Pollution discharged into the atmosphere from smokestacks, other vents, and surface areas of commercial or industrial facilities; from residential chimneys; and from motor vehicle, locomotive, or aircraft exhausts.
Release of pollutants into the air from a source. We say sources emit pollutants. Continuous emission monitoring systems (CEMS) are machines that some large sources are required to install, to make continuous measurements of pollutant release.
Discharge of substances to air, land and or water.
amount of substance that is released into the atmosphere
Waste released or emitted to the environment. The term is commonly used in referring to discharges of gases and particles to the atmosphere, i.e., air pollutants, and also is used in referring to particles or energy released radioactively. Sometimes the term is used broadly, encompassing any pollutant discharge.
Direct release of a pollutant to air or water as well as the indirect release by transfer to an off-site waste water treatment plant
A discharge or release of pollutants into the air, such as from a smokestack or automobile engine.
