Pesticide Registration

Tests:

  • Toxicology

    • Single dose

Pesticide Registration

Tests:

  • Toxicology

    • Lifetime exposure

      • Reproduction

      • Mutations

      • Cancer


Pesticide registration10 l.jpg
Pesticide Registration

Tests:

  • Environmental fate

    • Breakdown in soil, water


Pesticide registration11 l.jpg
Pesticide Registration

Tests:

  • Environmental fate

    • Movement

      • Runoff

      • Leaching

      • Drift


Pesticide registration12 l.jpg
Pesticide Registration

Tests:

  • Ecological effects

    • Birds

    • Fish

    • Non-target plants


Pesticide registration13 l.jpg
Pesticide Registration

Tests:

  • Residue Analysis


Pesticide registration14 l.jpg
Pesticide Registration

Residue Analysis:

Pesticide applied according to proposed label rates & procedures.

Then pesticide residues on crops are measured.



Pesticide tolerances l.jpg
Pesticide Tolerances

The amount of pesticide residue that will be legally allowed on food.

10 X, animal test

300 ppm =No Effect Level

30 ppm


Slide19 l.jpg

10 X, animal test

10X, human variability

300 ppm =No Effect Level

30 ppm

3 ppm

10X, human variability

10x, kids

300 ppm =No Effect Level

30 ppm

3 ppm

0.3 ppm


0 3 ppm spread over 5 crops tolerance l.jpg
0.3 ppm spread over 5 crops = Tolerance

Average 0.06 ppm each

Residue Testing

Tolerance Setting

Pesticide Registration

If residue < tolerance,

Pesticide registered


Safety nets l.jpg
Safety Nets

  • Never eat all crops in one day!

  • Every day!

  • For 70 years!


Safety nets24 l.jpg
Safety Nets

  • Never eat all crops in one day!

  • Every day!

  • For 70 years!

  • Max rate not used!

  • To all fields!

  • To all parts of field!

“Reasonable certainty

that no harm will result

from aggregate pesticide exposure”


Slide29 l.jpg

The

Risk Cup

EPA has compared setting tolerances to filling a “Risk Cup”


Slide30 l.jpg

The

Risk Cup

Exposure that you could receive every day.

For 70 years.

With no significant risk of long term, health effects.

EPA must consider

aggregate exposure

Pets

Home

Garden

Food


Slide35 l.jpg

Aggregate Exposure

Chlorpyrifos(Dursban, Lorsban)


Slide36 l.jpg

Dietary/ Non-Dietary Exposure

&

Common Mechanism of Toxicity


Slide37 l.jpg

If the risk cup gets full,

manufacturers could reduce risk…


Slide38 l.jpg

By eliminating uses…

… Especially minor uses!
