Re: HYB: removing germination inhibitors - part 1


Caution against any mustard  compounds.  When I worked in a Chemical
pilot plant 10 years ago, I filtered a large quantity of benzyl mustard
into an open filter and went out later for a cigarette soon after.  As I
lit up, I noticed my face in the reflection of the window had what
looked like a bad Poison Ivy like rash, it ended up all over my chest
and arms as well.  It was pretty scary !  Everything healed though.  

I'd be interested in the Sulfuric acid data if you can find it.  It's
safe to work with if you treat it with respect and wear the required
safety protection.

Vacation now over after almost 3 weeks of rain ;-(
