Dust sampling can be done with a filter, a sticky pad, or other techniques, and can help in assessing particulate air pollution (#pm or #dust) -- see https://publiclab.org/wiki/pm for more. This is also a helpful prerequisite step for viewing particulate pollution through a microscope, if it's big enough to be seen! https://publiclab.org/wiki/microscopes ## Questions Please help build out this resource by asking questions here: [questions:dust-sampling] **** ## Activities [activities:dust-sampling] > We would **love** to see guides to collecting dust for analysis. If you know of a technique, or an online or print resource for this, please share it as an activity above! ...
