Petrochemicals
It's not just the nitro. methenol is made from natural gas. It's not much different than oil. I live by Dow Chemical near the Texas coast and I can tell you honestly that these chemicals and bi products and so on are horrible. Toxins are in everything these days, and a buildup is absolutely possible and causes so many problems. I know nothing about what happened with porkchop, but I can say that it is difficult to detoxify the body of heavy metals, chemicals etc...
