A reader shared this with me today, and I wanted to make sure to share it with you! This chart shows how big a particle of Lead dust is compared to particles of other items you may be familiar with. This is a great illustration to help folks conceptualize (something that is also attempted in detail in this article here) exactly how tiny Lead dust particles actually are (helping to generate a better understanding of why it is that even invisible (microscopic) amounts of Lead can harm humans)! If you want to see the original source for this chart, please just click the image. Thank you so much for checking this out – it is really fascinating to see this explained / demonstrated in this way.
I wonder what they mean by lead dust. I would have thought that, like some of the other things on the list, it depends on how the dust was created. Also, do they mean pure metallic lead or dust made of compounds of lead?
I have submitted a question to them and will share it here if I get an answer.
