Built Environment Sampling #1 done!

Today the students from CE369L have been sampling in class (oh well, we started by 7am). The 11 groups of students were sampling not only in the actual classroom but also in the corridor, the adjacent hall and outside. Bioaerosol samples were taken indoor and outdoor by using SKC impingers and Button Samplers. A baseline was established before the students came in and the "in class" measurements started as early as 8am. Sleepy faces could be observed around .

Dust had been collected in plates for 5 days. A variety of surfaces were wiped and swabbed too. The biological samples were complemented with #metadata: CO2, particle counts, surface temperatures, relative humidity and temperature, air flowrates (for the whole class and on the sample locations) and pressure differences (between class and corridor). Here some pictures of the sampling event.

It was very fun and instructive. A great experience!
