That relates to environmental contamination, and will not apply to all populations. Bioaccumulation of toxic elements by fungi is both a useful phenomenon for things like biological 'mining' and bioremediation, and is a legitimate concern when collecting otherwise edible fungi. Presumably you also avoid tuna and similar fish species which bioaccumlate mercury?"Mushrooms (Cantharellus cibarius and Amanita fulva) were blanched (parboiled) and pickled using different treatment conditions with the aim of carrying out the study into effect on removal of toxic mercury (Hg)"

Not as probably as with something like wolfsbane or jequirity. Tobacco has more wiggle room by comparison but, yeah, nicotine poisoning is not fun and could be used as part of an ordeal process if ones culture demanded it.eat tobacco and you will probably die
I am thinking of baking baking soda and freebasing some shit.
You will have to eat something so you'll get some shit to freebase (just don't eat the tobacco, please) unless you have housemates/family - or maybe go outside and see what you can find. The local dog park might be a promising place to start. Just think, this could be the start of a beautiful canine jenkem journeyI didn't have any so I had to bake some tobacco instead.

Sorry, what for?use diaminomethanal instead.
How does urea destroy microplastics?I use it to create inert atmospheres and to destroy microplastics.
so diaminomethanal+certain bacteria=ammonia+carbon dioxideHow does urea destroy microplastics?
Yes, but most plastics aren't produced from urea…so diaminomethanal+certain bacteria=ammonia+carbon dioxide
