Reproductive toxicology. Boric acid.
Boric acid (BA), widely used for both medicinal and nonmedicinal purposes, was known to adversely affect reproduction and fertility in rodents. NIOSH, in evaluating the literature prior to writing a Criteria Document, asked NIEHS to perform an RACB study on BA to generate both structural and functional data to be used for setting exposure criteria (Fail et al., Fundam Appl Toxicol 17:225-239 [1...
متن کاملBoric Acid and Borates
Boric acid and its chemical relatives are pesticides that are derived from the element boron. Boron rarely occurs alone and is typically found in combination with other elements; common combinations are boric acid or borates.1 Unlike many pesticides which are synthetic compounds,2 boric acid and related pesticides are naturally occurring compounds.1 Boron compounds are widely found in rivers, s...
متن کاملComplexation of Nickel Ions by Boric Acid or (Poly)borates
An experiment based on electrochemical reactions and pH monitoring was performed in which nickel ions were gradually formed by oxidation of a nickel metal electrode in a solution of boric acid. Based on the experimental results and aqueous speciation modeling, the evolution of pH showed the existence of significant nickel-boron complexation. A triborate nickel complex was postulated at high bor...
متن کاملaccelerated autocondensation of quebracho tannin wood adhesive by boric acid
quebracho tannin wood adhesive in non formaldehyde approach has low autocondensation rate and needs more press time than formaldehyde-based wood adhesives to produce wood composites. in this study, boric acid was used to increase autocondensation rate of quebracho tannin adhesive to make poplar plywood. the main ingredients of the adhesives include quebracho tannin, naoh, hexamine, boric acid a...
