The normal cherry picking and confirmation bias approach to science of the ideologically driven is annoying enough. At least we can discuss this and offer alternative scientific findings. And let’s face it – we are all prone to cherry picking and confirmation bias.
But some peopel carry this opportunist and naive use of science to extremes. This is particularly true of conspiracy theorists obsessed with contaminants. For them, the very fact that a contaminant is detected, irrespective of its extremely low concentration, is “proof” of contamination. The means they can feed their obsession with analytical evidence which actually does not support their argument.
Reminds me of the old days when some people used to claim radioactive contamination of the environment because they could get a few background clicks on a Geiger counter.
Here’s one from NORTHLAND NEW ZEALAND CHEMTRAILS WATCH. (It is hard to get a more extreme conspiracy theory than chemtrails!). In Rainwater Test Result From Nelson Shows Aluminium, Barium & Strontium Present they cling to an analytical report showing the presence of “three elements known to be linked to geoengineering globally” in Nelson rainwater.

For them, simply the ability to detect something (or maybe even to include the elements in an analytical report, feeds their conspiracy theory.
Despite the fact amounts detected are barely over the detection limit!
Of course, when we reject this sort of “evidence” as meaningless this becomes evidence for another conspiracy theory.
