We’ve all used the world wide web to collect information on how to do most anything, from tying a necktie to understanding quantum mechanics (OK, enough with my web searches!). But a study published in the Journal of Exposure Science and Environmental Epidemiology puts a new “spin” on using the web to measure indoor air quality – using ever present spider webs to collect indoor air pollutants for analysis.
The webs are typically located in hard-to-reach places and constantly collect VOC’s, PAH’s, dust, and other airborne contaminants. The condition of the web tells scientists how long it has been in place. Using naturally occurring webs replaces the need for expensive air filtration equipment with long wait times to get results. So, maybe it’s not a bad idea to leave that spider web alone. It may help inform engineers on the type of filtration needed to maintain occupant health. – Steve Terry, DTC HVAC & Refrigeration Instructor
