Has there ever been studies that test what's left in a vapour-bong water after vaping?

Basically I was just wondering whether anyone had ever tested the water from a bubbler that has strictly been used for vaping to see what is left in it after a session. Wondering whether a lot of Terps or particulates etc get filtered out by the water or not.

When my glass is clean, I can sometimes see particles floating around along with the bubbles after taking a hit.

I have used a ammonia detection kit for fish tanks to test the vapor water before and after use. The water has higher levels of ammonia after being used. I propose that the water is absorbing some ammonia from the vapor.

The amount of particulate matter would depend on the vaporizer used and the consistency of the herb. In my opinion
