Read the section on the concentration of fluoride in bone and teeth which increased in a dose related manner. The report states, "The release of the fluoride ion and its distribution in the body have not been clearly characterized (page 254-255)." In a discussion on water sediment systems, "Another hydrolysis study demonstrated that tolylfluanid was hydrolyzed into DMST, fluoride ion, chloride ion, sulfur and carbon dioxide (page 262)."

The study also states, "Studies that would provide information useful for continued evaluation of the compound
Further characterization of the distribution and excretion of fluoride and thiazolidine-2-thione4-carboxylic acid, particularly in milk (page 257)"

On September 25, 2002, US EPA approved tolerances for tolylfluanid for 4 imported commodities. In its Final Rule, EPA cited several bone effects. However, EPA never discussed fluoride concentrations. (See Federal Register below).

BAYER - Pesticide Tolerances - Classified as "Likely to be carcinogenic to humans," EPA approves Pesticide Tolerances in or on imported apple, grape, hop, tomato. FINAL RULE.

- Approved Tolerances Bayer's Tolerance petition of Aug 11, 1997
Apple 5.0 ppm same
Grape 11 ppm 5.0 ppm
Hop 30 ppm same
Tomato 2.0 ppm 1.0 ppm

-- Classification: ``Likely to be carcinogenic to humans'' by the oral route, based on thyroid tumors in high-dose male and female rats. The FQPA SF Committee further recommended a linear low-dose extrapolation approach for the quantification of human cancer risk based on the thyroid tumors in rats. Q1* = 1.59 x 10-\3\ based upon male rat thyroid adenomas and/or carcinomas combined.
-- The cancer risk estimate is
1.2 x 10-\6\ for the general U.S. population (1.2 cancers per million).
-- Prenatal developmental toxicity/rabbit LOAEL = 70 mg/kg/day based
on increased malformations (arthrogryposis of front extremities and small orbital cavity/folded retina) and variations (floating ribs and accelerated ossification).
-- 2-Generation reproduction and fertility effects (rat): Parental/systemic- LOAEL = 15.9-21.5 mg/ kg/day, based on hardened crania of P generation animals
-- Combined chronic toxicity/carcinogenicity rodents (rat): NOAEL = 18.1/21.1 mg/ kg/day (M/F); LOAEL = 90.1/105.2 mg/ kg/day (M/F), based on skeletal changes. Evidence of thyroid follicular cell adenomas and/or carcinomas in high- dose males and females.
-- Combined chronic toxicity/carcinogenicity rodents (rat): NOAEL = 20/20 mg/kg/ day (M/F); LOAEL = 80/110 mg/kg/day (M/F), based on bone hyperostosis in males and females Evidence of thyroid follicular cell adenomas and/or carcinomas in high- dose males and females.
-- Carcinogenicity rodents (mouse): NOAEL = 76.3/123.9 mg/kg/day (M/F) LOAEL = 375.8/610.8 mg/kg/day (M/F), based on skeletal, liver, and kidney changes. No evidence of carcinogenicity.
-- Non-guideline (rat) thyroid function: Thyroid-stimulating
hormone levels significantly increased (168-425%) in high-dose males and females. Slightly increased T3 levels in males rats above 119.3 mg/ kg/day.
-- Acute oral neurotoxicity/rat. LOAEL = 150 mg/kg/day based on FOB effects (pilorection, decreased activity, gait abnormalities, decreased body temperature, and/or decreased rearing).
