Always been kind of obvious that we have ubiquitous outside mold in our air. I presume they count it, whatever "it" is, like they do pollen and other particulates. But traditionally not "shards".
Which leads me to ask. Has "it", always been just spores they count? And with current tech "shards" go completely under the radar? Then the question is what about indoors?
And are shards that dangerous? Let's put things in perspective. A spore can grow into an organism inside of your body.
But then tiny particles (any kind) can from my limited understanding, get past your lungs defenses to expel them. And end up lodged in your air sacs. What kind of consequences does that lead to?
And could a test be developed to diagnose the pathology.
