PM2.5

 

 

12 MAY 2016 | GENEVA - More than 80% of people living in urban areas that monitor air pollution are exposed to air quality levels that exceed WHO limits. While all regions of the world are affected, populations in low-income cities are the most impacted.

According to the latest urban air quality database, 98% of cities in low- and middle income countries with more than 100 000 inhabitants do not meet WHO air quality guidelines. However, in high-income countries, that percentage decreases to 56%.

 

2 May 2016 - This updated database contains results of urban outdoor air pollution monitoring from almost 3000 cities in 103 countries
Air quality is represented by annual mean concentration of fine particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 microns).

The database aims to be representative for human exposure, and therefore primanty captures measurements from monitoring stations located in urban background, urban traffic, residential, commercial and mixed areas.

 

Emerging evidence suggests that short episodes of high exposure to air pollution occur while commuting. These events can result in potentially adverse health effects. We present a quantification of the exposure of car passengers and cyclists to particulate matter (PM).

We have simultaneously measured concentrations (PNC, PM2.5 and PM10) and ventilatory parameters (minute ventilation (VE), breathing frequency and tidal volume) in three Belgian locations (Brussels, Louvain-la-Neuve and Mol) for 55 persons (38 male and 17 female).

BRAL organiseerde laatst een infoavond over de luchtkwaliteit in Brussel. Daar is de laatste jaren heel wat om te doen, aangezien we beetje bij beetje weet beginnen te krijgen welke de impact is van luchtvervuiling op ons lichaam. Meten is weten, dat bevestigde het exposé van Olivier Brasseur, onderzoeker bij Leefmilieu Brussel.
