Maybe it does, maybe there are higher concentrations of chemicals in some areas then others. There are a lot of things we don't know about the smiles and how things work here. We know that Kaido and his people receive the best of everything so it is possible that if there are chemicals or materials in the food and water that they themselves wouldn't eat it. We need to know more about how exactly things work before we can make an exact statement. We do know that some of the water is presumably poisonous or toxic which is likely due to the heavy concentrations of pollution and chemicals in the water.
