Title: I inhaled aqua regia twice. How bad is it?
Post by: aquaregia on March 27, 2022, 02:31:35 PM
I worked in a lab unsupervised and inhaled aqua regia once two weeks ago (aqua regia was freshly made then), then another one the previous week (aqua regia was a week old, but still had a strong smell). It was sealed in an Erlenmeyer flask for days (it was 60 ml or so). I wasn't wearing a mask or protection glasses. It was directly under my nose. How bad is it? Should I see a doctor?

I'm not experienced with lab equipment or any chemicals. I wasn't aware it was that bad till after I inhaled it and felt a sting in my nose.

If it was many days ago and you have no observable symptoms (like cough) you should be OK. Gases that are emitted are strong irritants and they can quickly destroy tissues, but I am not aware of delayed effects (at least if it is just a random exposure, not something repeating every day).

A bit like contact with something hot - you were either burnt to the point of needing medical attention, or it was just unpleasant but no need for a doc.

Thank you for the reply, I appreciate it!

This part scares me :C I wanna go, but I doubt the doctor has prior experience to this chemical or would even know what it is.

You would just tell the doctor you inhaled concentrated acid fumes. They would treat accordingly, eg pulmonary edema.
