English

Subject field(s)
  • Pollutants
  • Air Pollution
DEF

A source of pollution which can be regarded as a precise spot.

CONT

Large point sources of CO2 include large fossil fuel or biomass energy facilities, major CO2-emitting industries, natural gas production, synthetic fuel plants and fossil fuel-based hydrogen production plants.

OBS

point source; PS: term and abbreviation standardized by Environment Canada and the Translation Bureau for use in the Air Pollutant Emission Inventory Report.

French

Domaine(s)
  • Agents de pollution
  • Pollution de l'air
DEF

Source d'émissions limitée à un seul point bien circonscrit.

CONT

On opère souvent une distinction entre les sources ponctuelles, importantes et concentrées, et les sources diffuses de tailles limitées et à effluents plus dilués. Dans cette approche, les sources ponctuelles relèvent plutôt d'installations industrielles tandis que les diffuses sont davantage catégorisées dans le domestique.

OBS

source ponctuelle; SP : terme et abréviation normalisés par Environnement Canada et le Bureau de la traduction dans le cadre de l'Inventaire des émissions de polluants atmosphériques.

Spanish

Campo(s) temático(s)
  • Agentes contaminantes
  • Contaminación del aire
DEF

Record 4 2002-01-29

English

Subject field(s)
  • Air Pollution
CONT

Atmospheric models are not yet available to provide a detailed, quantitative relationship between NOx emissions and acid deposition; however, on the simplifying assumption that the nitrate contribution to acid precipitation can be linearly related to NOx emissions then, from Table 6, the contribution of LDV's, which are the largest individual source of NOx emissions in the transportation sector, would be about 9% of precipitation acidity.

OBS

As opposed to area source.

French

Domaine(s)
  • Pollution de l'air
OBS

Terme du langage courant utilisé pour désigner séparément l'une ou l'autre des "sources multiples", ou pour désigner une source qui se définit par opposition à une source étendue.
