Air Quality Measurement Gets Personal with Advanced ...

2020-08-04· Two important indicators for air pollution measurement are small particulate matters (PM) of µm (microns) or less () and volatile organic compounds (VOCs). They are, for example, emitted in households by fireplaces and candles during combustion processes. Everyday objects such as cleaning supplies, furniture, or textiles can also emit VOCs. This article provides insights into new PM2 ...
