the group who's investigating knows how to deal with stuff like this.
can't tell you more at the moment.
i'm back when results of probes are out!
yust an idea
hippolito mejia and rene ledesma are such as shure that this stuff is not toxic so my proposition:
hippo and ledesma will invite the press to arroyo barril.
there under control of the whole press, they mix a drink of 100 gramm ash into 1 liter whater.
the ash is not toxic, so prost drinking it!
