I've had a question recently from a friend in Mobile, AL who is working with someone experiencing an increase in exposure to dust from a nearby roadway. They are interested in collecting some visual data around accumulation of dust. I know a few people on here have explored sticky pads, observed accumulation of dust on glass and other materials. Is there anything specific you would recommend they use to observe this?
Response from @wicca coming in from the midwest list: Well, take the municipal government out there to experience the experienceable. If the plant is closed during evening (municipal board hours) then set up a few board members to go in the afternoon. Talking to the companies is useless ... have the neighbors who have been impacted done anything ... attend board meetings or talked directly to the companies? Final straw ... get an attorney and file a Nuisance complaint if you have one .. or something similar.
I'm probably preaching to the choir but what the heck ...
From @jeffalk on the midwest list:: @ramseysprague You say " I was back there for an hour and had to evacuate twice due to the dust. “ What monitor are you using for what particulate size and what did it show for the hour you were referencing? If it is so visible perhaps a video would work? Or hanging out a clean laundry and showing the effect on the clothes? Larger particulate are assumed to be “less of a health hazard” and the standards for TSP (total suspended particulate) allow for large amounts. Sometimes large quantities of dust are more of a safety hazard than a health hazard, eg producing poor visibility for driving, etc. The standards are also over a 24 hour period so if excessive dust is only for a small fraction of 24 hours it will not average as high. If you want more comments please supply more detail.

Some people have been using window panes to collect dust. Use an old one, clean it up good; collect the dust and take a scraping that can be tested. It can provide some very revealing data to the eye and to the microscope.
On this facebook page there are some interesting methods used to collect dust: one involves using a large thick filter with a window fan. Inexpensive method costing about $50.00. There are other ideas.
