POLLUTION ANALYSIS [13 records]

Record 1 2022-10-12

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
  • Environmental Studies and Analyses
CONT

Trajectory analysis uses climate re-analysis products to track a parcel of air : typical applications would be to track a pollution plume or volcanic eruption plume. Back trajectory analysis is the inverse of this technique, and allows one to answer the question, "where did a parcel of air originate from, and where did it uptake its moisture?"

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
  • Études et analyses environnementales
CONT

Une analyse de rétrotrajectoire, qui permet de définir le trajet parcouru par un polluant avant sa détection en un point précis, indique que le SO2 [dioxyde de soufre] proviendrait du parc industriel.

Key term(s)
  • analyse de rétro-trajectoire

  • Air Pollution
CONT

The perturbation of the ozone layer, through the input of additional nitrogen oxides, is only one basis for concern about nitrogen pollution. A cost/benefit analysis of the nitrogen fertilizer impact on the ozone layer probably cannot be made at this time and in any case, it should not be make independently of other nitrogen problems.

OBS

nitrogen pollution; nitrogenous pollution: terms extracted from the “Glossaire de l’environnement” and reproduced with permission of the Organisation for Economic Co-operation and Development.

French

Domaine(s)
  • Éléments et composés chimiques
  • Agents de pollution
  • Pollution de l'air
DEF

Pollution causée par un ou plusieurs dérivés de l'azote.

OBS

Le déterminant «azoté» n'est pas synonyme de «nitré».

OBS

Certains puristes désapprouvent l'emploi du déterminant «azoté», directement accolé au terme pollution; cet usage est pourtant largement répandu dans les textes techniques.

OBS

pollution par l'azote; pollution azotée : termes extraits du «Glossaire de l’environnement» et reproduits avec l’autorisation de l’Organisation de coopération et de développement économiques.

OBS

... is an approach used by the Ontario Ministry of Environment to encourage and assist industry to adopt Cleaner production or green processes and practices. It is a voluntary initiative to cut costs by improving resource efficiencies, reducing waste and improving the environment. The analysis allows companies to identify ways to reduce their use of energy and water, to prevent environmental pollution and to minimize all forms of waste.

[...] est une initiative du ministère de l'Environnement de l'Ontario destinée à encourager et à aider l'industrie à adopter des méthodes de production plus propres ou des procédés et pratiques écologiques en vue de couper dans les coûts en accroissant l'efficacité des ressources, en réduisant les déchets et en améliorant l'environnement. L'analyse aide les entreprises à trouver des façons de consommer moins d'énergie et d'eau, de prévenir la pollution de l'environnement et de minimiser toutes les formes de déchets.

CONT

Gas chromatography(GC). The use of GCs for detecting organics is rapidly becoming a standard technique in air pollution analysis.... GC systems are reliable, expensive and extremely sensitive.... Commercial GC systems are provided by many companies, and systems by Finnegan, Hewlett-Packard and Varian are among the better known. Commercial ambient monitoring GCs are made by Bendix(8200) and Beckman(6800) and are called Ambient Hydrocarbon Monitors. Total organic content of the air with and without methane is measured with GC-FID systems.

Filter Sampling. Particulates are extremely varied for their composition. The monitoring of particulates with High Volume(Hi-Vol) samplers and other filter media varies from a simple colorimetric measure of the coefficient of haze(CoH) to the use of neutron activation analysis, atomic absorption spectroscopy, etc. for metal concentrations and gas chromatography for organic composition. Heavy metal measurements for lead, cadmium, chromium, vanadium, and nickel are common in urban areas such as with the National Air Pollution Surveillance Network(NAPS).

Microscale. Analysis of pollution dispersion on the microscale(< 1 km) is by its nature more specific to particular air pollution problems. Examples of these are emissions from vehicle traffic along highways, downwash around buildings, inner-urban pollutant effects, etc.... An important field in microscale APM studies is analysis of the mechanisms in pollutant deposition and fluxes to vegetation, water and soil.
