Therefore, this study explores the effects of oral administration melamine or melamine and cyanuric acid for 28 days on the ovaries of female rats. Rats that were exposed to the mixture exhibited reduced ovarian and uterine weights, a sh...
متن کاملDetermination of Melamine and Cyanuric Acid Residues in Infant Formula using LC-MS/MS
A liquid chromatography triple quadrupole tandem mass spectrometry (LC-MS/MS) method for residues of cyanuric acid (CYA) and melamine (MEL) developed by the Center for Veterinary Medicine (CVM) has been adapted for use with infant formula. This method consists of an initial extraction with 2.5% aqueous formic acid, followed by a series of filtration, centrifugation, and dilution steps. Both com...
متن کاملInterference in Melamine–based Determination of Cyanuric Acid Concentration
Isocyanuric acid (commonly referred to in the swimming pool/spa industry as cyanuric acid, stabilizer, conditioner, CYA, etc., and referred to simply as cyanuric acid in this paper) is a member of the symmetrical triazine family, and it is used in outdoor swimming pools and spas to protect chlorine against loss from ultraviolet radiation from the sun.
