¹Site types are described as follows: Kerbside: A site sampling within 1 metre of the edge of a busy road. Roadside: A site sampling between 1 metre of the edge of a busy road and the back of the pavement. Typically this will be within 5 metres of the road, with a sampling height of 2–3 metres. Urban Centre: A non-kerbside site, located in an area representative of typical population exposure in town or city centres (e.g. pedestrian precincts and shopping areas). This is likely to be strongly influenced by vehicle emissions, as well as other general urban sources of pollution. Sampling at or near breathing—zone heights (1.4–4 metres) will be applicable. Urban Background: An urban location distanced from sources and therefore broadly representative of city—wide background conditions e.g. elevated locations, parks and urban residential areas. Suburban: A location type situated in a residential area on the outskirts of a town or city. Will be influenced by several sources of pollution including traffic, commercial, space heating. regional transport. urban plume downwind of a city.
²Pollutant species: 03—ozone; NO,—oxides of nitrogen (include nitrogen dioxide); CO-carbon monoxide: S0,—sulphur dioxide; PM,,,—particulate matter of aerodynamic diameter less than 10 micrometres. PM,0 monitoring is carried out using either the TEOM (Tapered Element Oscillating Microbalance; T in table above) or Gravimetric sampling (G in table above). Monitoring is by TEOM alone unless otherwise stated.
³London Marylebone Road is a research site and is used for a variety of monitoring projects mostly involving measurement of airborne particulate matter.
