Pollution & Environmental Health

  • Diseases are sometimes caused by pollution and toxicity in the environment. Point sources, non-point sources, and mobile sources of pollution must be considered
  • Microbes include protists, bacteria, and viruses. Epidemics and pandemics can result if the spread of these microbes gets out of control
  • Heavy metals (like mercury, nickel, lead) can be found in soil or water and end up in bodily fat. There is an expected body burden for these heavy metals
  • Biomagnification (or bioaccumulation) can magnify the concentration of chemicals and heavy metals as they move up through a food chain or web
  • Organic compounds, persistent organic pollutants (POPs) like PCBs, and DDT, and hormonally active agents (HAAs) can negatively impact species
  • Thermal pollution, noise pollution, and light pollution can impact our environment and quality of life
  • Particulates (particulate matter) like asbestos can negatively impact human life, especially when it comes to respiratory health
  • Electromagnetic fields (EMFs) come from all kinds of electronic devices. Their full impact is not yet fully understood
  • When it comes to pollution exposure and assessment of risk, LD-50, ED-50, and TD-50 must be considered
