• hepatic disease

  • dermal effects

  • ocular effects

  • musculoskeletal effects

  • Pyridostigmine bromide and long-term adverse health effects

  • Exposure to sarin at low doses insufficient to cause acute cholinergic signs and symptoms and subsequent long-term adverse health effects

  • Anthrax vaccination and long-term adverse health effects

  • Botulinum toxoid vaccination and long-term adverse health effects

  • Multiple vaccinations and long-term adverse health effects

Limited/Suggestive Evidence of No Association

Evidence is consistent in not showing a positive association between exposure to a specific agent and a specific health outcome after exposure of any magnitude. A conclusion of no association is inevitably limited to the conditions, magnitudes of exposure, and length of observation in the available studies. The possibility of a very small increase in risk after exposure studied cannot be excluded.

  • Exposure to uranium and lung cancer at cumulative internal dose levels lower than 200 mSv or 25 cGy

  • Uranium and clinically significant renal dysfunction

Consensus Not Reached on Category of Association

  • Tetrachloroethylene and dry-cleaning solvents and lung cancer

  • Trichloroethylene and cervical cancer

  • Solvents and kidney cancer

  • Benzene and solvents and brain and other central nervous system cancers

  • Parental preconception exposure to solvents and childhood leukemia

  • Organophosphorous insecticide exposure without OP poisoning and long-term neurobehavioral effects (that is, abnormal results on neurobehavioral test batteries and symptom findings)
