discharge effluent release Release of a substance from a source, including discharges to the wider environment.

A release of combustion gases and aerosols into the atmosphere. 

Discharge

The discharge (e.g. solid, liquid or gaseous substances, sound) originating from a source, e.g. industrial plant, household, traffic.

An emission is the phenomenon of sending out electromagnetic waves. The source of a radiation is defined as an emitter.

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.

Release of pollutants into the air from a source.

A substance discharged into the air, especially by an internal combustion engine. The majority of the substance consists of un-burned hydrocarbons that react in the atmosphere to produce ground-level [..]

Pollution discharge from a source.

Discharge of electromagnetic radiation from an object.

The release of a substance to air (eg the discharge of a pollutant from vehicle exhaust)

pollution discharged into the atmosphere from smoke- stacks, other vents, and surface areas of commercial or industrial facilities; from residential chimneys; and from motor vehicle, locomotive or aircraft exhausts.

the direct or indirect release of substances, vibrations, heat or noise from individual or diffuse sources into air, water or onto land.
