I wonder what clam is gathering with their buckets? Perhaps some raindrops. Only time will tell. W - a - a - y too technical for me!
You didn't have to tell us. We all know just about everything, especially science, is too technical for you.
Let me take you by the hand and lead you to the intent behind my bucket question. If testing air quality in buckets were so reliable or latest technology, I believe the EPA would have had those in place for eons. My question was what is commonly known as an ironic comment.
I took it to be more of a moronic comment.
They are collecting air samples. To do this at many places around the city and at many times of day, they can get a better idea of just how bad the air is and in what areas it is the worst.
The EPA could do this but haven't the budget. Appropriate the money and then ask them to do it.
