Animal studies

  • Bisphenol A (BPA) (found in some plastics,
    carbonless copy paper and can linings)
  • Perfluoroalkyl compounds (used in nonstick
    cookware and water-repellent and stain-resistant
  • Organotins (used in agriculture and industry, used
    as wood preservatives in marine areas)
  • Dithiocarbamates (found in cosmetics and
    agricultural products)
  • Nonylphenol (found in cosmetics and household
  • Fine particulate matter (air pollutant from burning
    fuels and wood, from road dust, aerosols and other
  • Organophosphate pesticides (used for termite
    control, in home garden products, and in some pet
  • Atrazine (pesticide used in agriculture that can
    contaminate drinking water)
  • Nicotine

Human studies

  • DDE (a breakdown product of DDT, a persistent
    pesticide that is now banned)
  • PCBs (persistent chemicals used as lubricants and
    flame retardants, now banned)
  • HCB (a persistent fungicide, now banned)
  • Oxychlordane (a persistent pesticide, now banned)
  • Beta-hexachlorocyclohexane (a persistent
    insecticide, now banned)
  • Dioxins and furans (persistent chemicals formed by
    incineration of PVC plastic and other substances)
  • Maternal smoking during pregnancy

Both animal and human studies

  • PBDEs (flame retardants that are still used in
    consumer products)
  • Phthalates (found in some plastics)
