1. What are the exact impurities that got into the food chain because of this? And
I've just checked some random comapny who sells sól wypadowa and the composition is like that:
max 0,2% H2O
K4Fe(CN)6 (without percentage)gumishu
I ask because one time they say sól wypadowa (and the first what I heard was that term), the other time sól przemysłowa, sól odpadowa...
2. If they can put industrial salts into the kielbasa, why can't they put some on the pavements too!
I don't quite understand you. I figure you wanted to ask why they can't put on pavements edible salt? The answer is simple edible salt is 4 times more expensive.
