A Small Dose of Persistent Environmental Contaminants


  • An Introduction to the Health Effects of Persistent Environmental Contaminants

 

Persistent Environmental Contaminants Dossier


Name: Persistent Environmental Contaminants

  • Have various names depending on agency - e.g. U.S. EPA: Persistent Bioaccumulative and Toxic (PBT) or United Nations: Persistent Organic Pollutant (POP)
  • Use: varies, often restricted or banned (but still present in the environment)
  • Source: industry, waste sites, food chain, and environment
  • Recommended daily intake: none (not essential)
  • Absorption: varies
  • Sensitive individuals: fetus, children, elderly, all species accumulate PBTs
  • Toxicity/symptoms: range of toxic effects including developmental, learning and memory, cancer
  • Regulatory facts: various local, national, and international agencies working to eliminate or greatly reduce
  • General facts: long history of use, bioaccumulates
  • Environmental: global environmental contaminants
  • Recommendations: avoid, work towards phaseouts
