One thing more i might add to this is that toxins sometimes increase the bodies demands for nutrients. For example copper is toxic above small quantities, and zinc is central to the body's system of dealing with it. If heavy metal increased in the soil due to industrialization at the same time it was being depleted, it could be a double whammy.
Early trains burned coal. Coal has some metal content in it. The soot will settle.

Meaning that while we get less micronutrients, we might have a higher need for them?
Great read! I wonder how much transportation changed in the late 1800s too. That is - memetically at least - when trains really started taking hold.
i.e, less walking?
Yeah, I feel like the question WTF Happened in 1880 deserves more attention from the authors.
