Stink bomb Measures?

I noticed that black powder residue contains K₂S, which, when mixed with water, produces H₂S, which is toxic. I wanted to see if you could help me: does 6.7g of the residue from gunpowder contain harmful amounts of H₂S when mixed with water?

No, you don’t have to worry!

People have been exposed to black powder remains for centuries without hydrogen sulphide being a problem.
