  • Some people who drink water containing Haloacetic Acids at higher than normal levels over many years may have a higher risk of getting cancer. (epicwaterfilters.com)
  • Instead, industrial routes include oxidation of 1,1,2-trichloroethane, hydrolysis of pentachloroethane, and the carboxylation of chloroform: CHCl2CH2Cl + O2 → CHCl2COCl + H2O CHCl2CCl3 + H2O → CHCl2COCl + 2 HCl CHCl3 + CO2 → CHCl2COCl + 1/2 O2 Hydrolysis gives dichloroacetic acid.

  • Producers Association (MPA), and Vinyl Acetate Toxicology Group (VATG), have spon- sored development of physiologically based pharmacokinetic (PBPK) models for nasal tis- sue dosimetry with, respectively, acrylic acid (AA), methyl methacrylate (MMA), and vinyl acetate (VA). These compounds cause lesions in nasal epithelial tissues and are clas- sified as "Category 1" gases within the U.S. EPA (1994) classification scheme. (cdc.gov)
