The researchers used airport visibility measurements (for PM2.5 only) and data from state-run air pollution monitors (for all other pollutants) to estimate pollutant levels over time for the zip code centroids of participants' work sites and residences.
These investigators found that estimating individual exposure to air pollutants from central-site outdoor pollution monitors may result in considerable error.
While air pollution monitors measure external concentrations, biomarkers reflect the internal dose of pollutants and may even be able to distinguish between multiple pollution sources (Mayeux 2004; Rylance et al. 2013).
Two portable carts containing continuous air pollution monitors were used to measure group-level microenvironmental exposures to traffic-related pollutants, including fine particulate mass (< 2.5 μm aerodynamic diameter; PM2.5), black carbon, and size-specific particle counts.
They're installing data-collecting rubbish bins, parking-spot finders and pollution monitors.
But in the South Bronx, from 2002 to 2005, air pollution monitors went mobile.
Air pollution monitors showed areas of Beijing had more than 256 micrograms per cubic metre of the poisonous particles.
All Britain's 433 local councils were asked by the British Lung Foundation (BLF) whether they placed pollution monitors within 10 metres of school grounds.
He said: "Worse, several air pollution monitors have been vying for the dubious honour of recording the first officially monitored breach of the nitrogen dioxide (NO2) legal limit in the world in 2016".

Sixteen scientists from eight international institutions worked with WHO on the analysis, which gathered data from 3,000 locations, using pollution monitors on the ground, modelling and satellite readings.
