OTHER FOREIN POLLUTANTS
Air pollutants tests should be also to find possile traces of nuclear plants contaminants. When the japan nuclear plant exploded it is said that traces were found in USA.
Another tests added should be to find traces of possible chemical pollutants thrown by chemtrails. It is very obvious when they come out amd tic tac toe oir skies with who knows what.
Dont be afraid of getting out of the box and push the limits of possibilities.
