Continuous and passive monitoring of nitrogen dioxide in UK homes.

The UK Building Research Establishment has carried out measurements of levels of nitrogen dioxide (N02) in 12 homes in the South of England. Two types of detection device were used: the Scintrex LMA-3 continuous N02 analyser and the Palmes passive diffusion tube. NO 2 concentrations were recorded using both devices in the kitchen, living room and a bedroom of each home for a period of a week. Gas cooking was observed to be the most important source of peak concentrations of N02 in the home.
