So have you looked up or know what PM 2.5 is?

I wanted to ask what you think about how it will affect bees?

If you look it up and look at the articles they say its an air debris. And its bad. Its very bad for humans. There are articles also showing how it skyrockets when volcanoes go off. And it follows the air trails potentially hundreds or thousands of miles from where it started. (This far traveling also supports the idea that its from volcanic activity. And it went up in numbers when the number of volcanoes increased.

Some ideas mistakenly state its a nuclear particle, but if that were true it would be in water as much as air. (Its mostly an air particle.)

I am not trying to create stress.

But we all see how bees are both tough and fragile at the same time. Things that resemble chemicals or aerosols sometimes can hurt them.

And if this is the case we should know early to work out how preventive measures.

Somewhere there is a bee preserved in amber which is said to be around 13 million years old, so as far as I am concerned bees have been there and done that. All you will do is stress yourself and end up living a miserable life worrying about things that may never happen. Carpe diem.

PM simply stands for "particulate matter" 2.5 means it is 2.5 microns in size. Another common measure is PM 5 and 10 for 5 and 10 micron particles, respectively. These particles can be anything--this measure simply refers to size, nothing more.

The reason they say PM 2.5 is "bad" is because that is the size that can get down deep into the alveoli of our lungs and get stuck there. Really has nothing to do w/ toxicity or radiation per se but if the particles are from a toxic or radioactive source then they can be toxic or radioactive. The only place PM doesn't exist is space.

This really is a measure for estimating chronic exposure for humans. High PM 2.5 exposure over a lifetime may lead to increased risks of lung cancer and such. Really what they are getting at is urban smog and such here.

I am not so sure particles do not exist in space as I have read somewhere that tons of space dust land on the Earth each year. FWIW.

Sorry, space dust should read star dust. So Tinkerbell is alive and well.

Of course it exists.
What you really mean - PMs concentration in the space is much lower than near the Earth's surface.

Johno my exact thoughts.
Seems bees and Volcanos have co existed for a long time.
13 million years is more than I thought but they did survive 2 major ice ages, and some little ones.
