Hm. I'm only going to talk about fluoride, because it's the easiest to pick on: yes, China does have dangerously high levels of fluoride in groundwater in some areas. Those levels are much higher than the levels added to water in Western countries, and, in fact, Western countries already implement policies to limit the concentration of fluoride that makes it into drinking water (so in, e.g., Colorado Springs, fluoride is removed): http://ehp.niehs.nih.gov/1104912/ http://ehp.niehs.nih.gov/1104912/ >Opportunities for epidemiological studies depend on the existence of comparable population groups exposed to different levels of fluoride from drinking water. Such circumstances are difficult to find in many industrialized countries, because fluoride concentrations in community water are usually no higher than 1 mg/L, even when fluoride is added to water supplies as a public health measure to reduce tooth decay. [emphasis added] Additionally, as even this week's Chicken Little proclaims: > “Not at all,” Landrigan said. “I think it’s very good to have in toothpaste.” --- of course! Do you really think that nobody studied the addition of fluoride to toothpaste when it was first adopted? http://onlinelibrary.wiley.com/doi/10.1002/14651858.CD002278/abstract http://onlinelibrary.wiley.com/doi/10.1002/14651858.CD002278... > "Seventy-four studies were included." The end. Fluoride is not a routine risk to neural health in developed countries.
