Finally, by the same token, breaking wind may also be very, very dangerous, as hydrogen sulfide is one of the smelly components in flatus.
Indeed, in the previous century quite a few sewer workers were overcome and died from "sewer gas."
I just decided to give away tonning. At least archivals ones and maybe play with watercolour or Tee just for the colour.
A guess fiber papers today are archival enough and will last longer than myself and my health.
Use archival fixing and wash procedures and your prints will last a long time. Use Agfa Stab or Tetenal Stabinal to protect prints (they don't change print colour but close attention to usage instructions must be followed).
These posts are quite ridiculous. Forget Photography and mildly dangerous chemistry.
Do you use Bleach to clean your toilet ? Sodium Hypochlorite is quite dangerous used incorrectly.
Brick or Tile cleaner ? Usually concentrated Hydrochloric acid.
Drain cleaner - sometimes Sulphuric acid (conc), other times it's the exact opposite Sodium Hydroxide (or PotassiumHyroxide) crystals.
Oven cleaner, usually based on Sodium or Potassiun Hyroxide.
It apalls me that chemicals we (as someone from a scientific background) treat with quite careful precautions get used as household products with little or no warnngs. OP get a reality check and move on alarmist posts are not needed at all.

The cleaning products and other household chemicals mentioned are capable of producing skin irritation and possible chemical burns. (I'm assuming that people have enough sense not to ingest them.) This is very different from systemic poisoning that can be caused by some photo chemicals. However each person must chose their own benefit vs risk decisions.
I can speak from personal experience that I'd much rather have permanent skin damage (not cancer) than permanent neurological damage.
Frankly I would rather not have either.
And no, I don't have bleach cleaner at home.
Finally someone got it right in this thread! Thank you.
I wonder if marciofs pumps his own gas? Or uses a propane gas barbeque?
I have no idea if self-service gas stations or barbeques are common in Germany.

There is nothing quite like getting a snoot full of hydrocarbons while you are pumping the fuel you are buying.
I don't have car and my oven is eletric.
But it is not the point.
I agree that if used in a safe manner there is no danger.
What I am saying is that I don't want use it myself.
I am not arguing against the product itsrlf.
...for the health?
I think that we all assumed that based on your question above that you had a desire to try toners but were just trying to avoid the more dangerous in terms of chimicals used or the processing method.
Normal printing might involve as many potential hazards as some if not all toners if they are handled correctly so maybe some here and that includes me were surprised at your decision not to try any toners
Now it seems that your question was simply a desire for knowledge and that toners were not something you had a great desire to try. That's fine as well.
