@pschwede wow! It is very surprising and scary for me, plastic is ubicuous! I never would though that plastic contamination could be so insidious! I am thinking on a proposition to an group of folks to try to determine the level of plastic contamination in the air of our city. How can we make a plastic (and other solids) trap? Is there any kind of blueprint with instructions to make these traps? Are these device just a deposition bins? Where solids precipitation occurs? What metodology do these people use to have these result?
Thank you very much in advance and sorry about my bad english.
