  • 1. Effects of Chemicals on Organisms By: Will Myers, Jc Dickson, & Zach Church
  • 2.
  • 3. DDT was produced in 1873. In 1939, DDT was discovered to act as a pesticide. This chemical saved the lives of millions of people who lived in malaria prone areas.
  • 4. An American biologist discovered in 1962 that DDT hurt bird populations.
  • 5.
  • 6. Potency of a chemical is how powerful it is. Any drug that produces a visible or measurable effect at a low dose is said to have a high potency.
  • 7.
  • 8. Individual susceptibility is different for all people because it is based on genetic and physical make up of an organism.
  • 9. A chemical's concentration is the amount of a substance in a given volume. By this, concentration can be solved knowing the mass & volume of a substance.
