1. Dust Deposition Monitoring is a method to capture deposited dust and estimate the deposition rates for a range of particulate matter sizes and typologies; 2. Particulate Matter monitors are tools to measure particulate matter (PM) of different sizes; 3. IMPACT consists of Prediction of indoor pollutant concentrations from outdoor concentration; 4. Polluttant monitoring is a measurement of concentrations of total VOCs, O3, NO2 and SO2, acetic acid and formaldehyde.
Potential Results
1. By exposing glass slides or carbon stubs, users can capture particles which are later analysied with an optical or SEM microscope. The images are post-processed in order to obtain the deposition rates of particles according to their size, the area coverage and the typology of the particles (fibres, coarse mineral particles, soot, spores...); 2. This tool consists of a number or mass concentration of particulate matter over time, daily, hourly or every minute. It can be used in different configurations depending on the type of PM of interest. It can measure in a range between 0.01 and 100 microns, from ultrafine particles to coarse dust. 3. IMPACT helps users predict the indoor/outdoor ratio of NO2, SO2 and O3, by calculating the deposition rate of these pollutants on indoor surfaces. Users need to describe the indoor environment by indicating the area of each surface type (e.g. paintings, plaster, wood...); 4. Pollutant monitoring allows to calculate average concentration of pollutants, indoor or outdoors, during weeks or months, or continuous data of pollution concentrations in a higher frequency (every minute, hour or day). This tool refers to a range of possible instruments and measuring principles, which can be installed in various combinations. Instruments can be hand held or fixed, capture long term data or time series.
