The instrument developed during the course of the pollution in streets project, the StreetBox, is now being commercially produced by Learian . We have monitored 45 houses or flats for CO, NO2 and humidity and dust mites, and linked the results to the type of ventilation in the houses. The occupants were asked to fill in a simple questionnaire. All of the data has been compiled into a single spreadsheet for analysis. The final report is available by request.
Carbon monoxide can cause injuries to health, see here.
The dwellings chosen were all low income housing with gas cooking and heating, all have been recently built. Craig Milliken, Ian Ridley, Elaine Clarke, Alan Young were all involved with this research. A full description of the project is available here. This consisted of an investigation of eight buildings. My part involved the monitoring of indoor to outdoor ratios of various pollutants, including CO, NO2 and SO2, and also air change rates by using CO2 decay.
