  1. We will talk about risk.

  2. Risk = Toxicity X Exposure = X

  3. Should we be concerned with pesticides? Ag Health Safety

  4. Glyphosate; 2,4-D; & chlorpyrifos residues have been found in farm homes.

  5. There is a relationship between Rotenone and Parkinson’s Disease.

  6. Isn’t rotenone a natural pesticide, and therefore safe?

  7. Rotenone is from specific tropical plant roots and stems.

  8. Rotenone is mildly toxic to mammals • Toxicity • Mildly toxic to mammals • Lowest lethal dose for child is 143 mg/kg • Human deaths rare – causes vomiting • Poorly absorbed by human GI, skin

  9. Rotenone is extremely toxic to fish.

  10. Rotenone was used as an insecticide.

  11. Pesticides derived from plants can be just as dangerous as synthetic chemicals.

  12. Toxicity is measured through LD50

  13. Milligrams per Kilogram • 1 Milligram = 0.0000352 Ounces • 30,000 Milligrams = 1.058 Ounces • 1 Kilogram = 2.2 pounds • 68.04 Kilograms = 150 Pounds

  14. Milligrams per Kilogram • 1 Milligram = 0.0000352 Ounces • 30,000 Milligrams = 1.058 Ounces • 1 Kilogram = 2.2 pounds • 68.04 Kilograms = 150 Pounds • Boric acid, oral LD50 > 10,000 mg/kg • Rotenone, oral LD50 = 132 to 1,500 mg/kg

  15. Arrange these materials in order from least dangerous to most dangerous, using LD50. • Alcohol • Aldicarb (Temik) • Ammonia • Arsenic • Aspirin • Botulinum • Dioxin • Glyphosate • Malathion • Metalaxyl (Ridomil) • Nicotine • Salt • Sugar

  16. Proper purchase can reduce risk.

  17. Purchase the least toxic pesticide that will do the job.

  18. Read and understand the label.

  19. Purchase the safest formulation.

  20. Pesticide formulations include solids.

  21. Pesticide formulations include solids.

  22. Pesticide formulations include solids.

  23. Pesticide formulations include solids added to water.

  24. Pesticide formulations include solids added to water.

  25. Pesticide formulations include liquids.

  26. Pesticide formulations include liquids.

  27. Pesticide formulations include liquids.

  28. Pesticide formulations include liquids.

  29. Pesticide formulations include aerosols.

  30. Pesticide formulations include fumigants. Which is best?

  31. Best Formulation? Consider Effectiveness? Exposure to applicator? Drift? Non-target species? Ease of use? Application equipment? Cost?

  32. When selecting a pesticide, consider Ready-to-Use.

  33. Risk = Toxicity X Exposure

  34. When purchasing a pesticide, check the container and label.

  35. Purchase only what is needed.

  36. Have clerk bag the pesticide separately.

  37. Proper transportcan reduce risk of exposure.

  38. Put in container to prevent tipping or spills. Pesticides

  39. Proper storage can reduce risk of exposure. Pesticide Storage

  40. Reduce exposure by wearing appropriate clothing.

  41. Different parts of bodies absorb pesticides at different rates.

  42. Activity: ID rates of absoprtion 1.3 1.6 2.1 3.7 4.2 5.4 11.8 1.0

  43. Activity: ID rates of exposure 3.7 4.2 5.4 1.3 1.6 2.1 3.7 4.2 5.4 11.8 2.1 1.0 1.3 11.8 1.6

  44. Reduce exposure by wearing proper clothing. Read the label.

  45. Samples of gloves.

  46. Wear appropriate clothing.

  47. Wear appropriate clothing.

  48. Guard against and prepare for spills.

  49. Kitty litter will absorb spills.
