Development of a Task-Exposure Matrix (TEM) for Pesticide Use (TEMPEST)

Area of Science:

• Occupational hygiene
• Environmental epidemiology
• Toxicology

Background:

• Pesticides are linked to health issues, including Parkinson's disease.
• Accurate exposure assessment is crucial for epidemiological studies.
• Identifying specific causative agents remains a challenge.

Purpose of the Study:

• To develop a comprehensive database for estimating historical pesticide exposure in Scotland.
• To create a tool that can enhance epidemiological research on pesticide-related health outcomes.

Main Methods:

• Identified pesticide use categories from occupational tasks in Scotland.
• Compiled data on typical pesticides, application methods, and concentrations across seven decades (1945-2005).
• Developed a Task-Exposure Matrix for PESTicides (TEMPEST) by quantifying exposure probabilities and intensities.

Main Results:

• Generated a database of 81 tasks and 846 task/pesticide/decade combinations.
• TEMPEST quantifies inhalation and dermal exposure probabilities and intensities for 10 pesticide groups.
• The matrix covers pesticide use in Scotland from 1945 to 2005.

Conclusions:

• TEMPEST offers a robust method for assessing historical occupational pesticide exposure in Scotland.
• The developed methodology can be applied to future epidemiological studies in Scotland.
• The TEMPEST approach is adaptable for retrospective occupational exposure assessments in other countries.
