Hypothesis

How did the 2000–2001 EPA regulations affect pest infestation levels, pesticide use, and permethrin exposure during pregnancy?

Conclusion

Pest infestations, pesticide use, and permethrin exposure increased after the restriction of organophosphorus insecticides.

Supporting Evidence

  • 88% of women reported using pesticides during pregnancy.
  • Self-reported pest sightings increased significantly after the regulations.
  • Detection frequencies of PBO and permethrin increased significantly over time.
  • Chlorpyrifos and diazinon levels decreased significantly over time.

Takeaway

The study found that after certain pesticides were banned, more pregnant women reported seeing pests and using pesticides, which might mean the new pesticides aren't as effective.

Methodology

The study involved 511 pregnant women from inner-city New York, who provided air samples and completed questionnaires about pest sightings and pesticide use.

Potential Biases

Participants may have underreported or misidentified pesticide products used.

Limitations

The study relied on self-reported data for pesticide use, which may not accurately reflect actual usage.

Participant Demographics

The cohort consisted of African-American and Dominican women aged 18-35 from Northern Manhattan and the South Bronx.
