What are the implications of quantum mechanics for our understanding of causality?

Normal air is largely opaque to UV with wavelengths shorter than 200 nm; oxygen absorbs "light" in that part of the UV spectrum. That is good news for us ... ... smaller is a nanometer. One thousand nanometers equals one micron ... –200-mesh would mean that all particles smaller than 200-mesh would pass through.
