During the Silvester fireworks in and around Zürich, many of you probably noticed that the air became foggy at some point. This can be explained by particles, emitted from the fireworks, accumulating in the boundary layer and acting as condensation nuclei for water droplets, which together with the air moisture and temperature led to fog […]
We introduced you to the concept of lung deposited surface area (LDSA) and our network of LDSA sensors in a previous post. The idea of monitoring very fine particulate matter (PM) comes from the knowledge that up to 90% of number concentration of ambient PM comprises of particles less than 500 nm of which ultrafine […]
For a few months now, our group and our students have been doing field measurements using Partector 2, a portable particulate matter (PM) sensor from naneos particle solutions gmbh. This very nice portable device utilizing induced currents (Fierz et al, 2014) measures the lung-deposited surface area (LDSA, see e.g. the paper of Sager & Castranova, […]
