“Water intake for a given age group varies substantially – around a factor of 100 between the highest and lowest consumption rates (discussed in the NRC report). The result of this is that for water fluoride at 1mg/L vs. water fluoride at 4 mg/L, there will be a huge overlap between the respective populations, with apparent differences only at the very highest water intakes. In other words, any effect seen at 4 mg/L is probably going to occur in some people at 1 mg/L (e.g., in the people with the highest water consumption or in people with impaired fluoride excretion), but this might easily be missed in the sample sizes typically used in studies.” See also: http://fluoridealert.org/content/kathleen-thiessen-phd/

Tsamtsouris, “Fluoride Levels and Fluorides Contamination of Fruit Juices,” Journal of Clinical Pediatric Dentistry, Vol. 16, No.1 (Fall 1991): 38-40. 42% of 43 samples had more than 1ppm fluoride. “Since it is a common practice to use fluoride-containing insecticide in growing grapes, it is believed that contamination of these juices is occurring.” Abstract. Range from 0.15 to 6.8ppm. Top three highest fluoride juices: Welch’s brand 100% grape juice 2.6ppm, Minute Maid brand white grape, 3, Gerber brand white grape, 6.8.

ISSN 0316-0114. “Teflon-lined cookware may contribute to the fluoride ingested by humans… Full and Parkins boiled fluoridated water at a moderate rate until a one-third or one-half reduction was attained, then determined the fluoride content of the residual water… In Teflon-coated ware, the concentration of fluoride ion increased to nearly 3ppm. This result requires confirmation; but, if its correct, then the release of fluoride into foods during cooking in plastic-coated wares requires investigation.” Cited by Fluoride Action Network.

Pg. 2-3, “After reviewing the collective evidence, including studies conducted since the early 1990s, the committee concluded unanimously that the present MCLG of 4mg/L for fluoride should be lowered. Exposure at the MCLG clearly puts children at risk of developing severe enamel fluorosis, a condition that is associated with enamel loss and pitting. In addition, the majority of the committee concluded that the MCLG is not likely to be protective against bone fractures.” See also: pg., 10, “Lowering the MCL will prevent children from developing severe dental fluorosis and will reduce the lifelong accumulation of fluoride into bone that the majority of the committee believes is likely to put individuals at increased risk of bone fracture and possibly skeletal fluorosis.”
