In the quote:
Chelyabinsk, a painting factory. Chemicals and all things. 100 meters through the road begins the territory of the zinc plant, spilling sulfuric acid with a constant accompanying aroma (and not only aroma). Someone has made a bed and grows tomatoes.

Boy, you did not understand. Chelyabinsky stalkers are so harsh that they grow vegetables in contaminated areas and then take them on the weight on Tuesday!
