Air pollutants and greenhouse gases

This section contains fact sheets in summary form on the main air pollutants and greenhouse gases (GHGs), grouped together according to the issue in question: greenhouse effect, acidification/eutrophication/ photochemical pollution, heavy metals, persistent organic pollutants and particulate matter. For each pollutant and GHG covered, the corresponding fact sheet describes its origin and effects on the environment and health, the main activities generating emissions of the pollutant or GHG in question, as well as emissions data and trends over time.

Greenhouse gases

Acidification, eutrophication, photochemical pollution

Particulate matter

This webpage deals with total suspended particles (TSP), particles less than 10 µm (10 microns) in diameter (PM10), particles less than 2.5 µm (2.5 microns) in diameter (PM2.5), particles less than 1 µm (1 micron) in diameter (PM1.0) and Black Carbon.
