[globalocchyg-list] Exposure to pesticides: Development of a Task-Exposure Matrix (TEM) for Pesticide Use (TEMPEST)

[Guest guest]

Saturday, June 28, 2010Hello !Thank you for sharing your findings. Without being familiar with your TEMPEST database -- do you think that some of the findings could be extrapolated to building indoor air quality residual exposures of the building tenants?With best personal wishes, Cutz

Exposure to pesticides: Development of a Task-Exposure Matrix

(TEM) for Pesticide Use (TEMPEST)

By F. D. Dick, S. E. Semple, M. van

Tongeren, B. G. , P. Ritchie, D. Sherriff, and J. W. Cherrie.

Introduction: Pesticides have been

associated with increased risks for a range of conditions including Parkinson's

disease, but identifying the agents responsible has proven challenging.

Improved pesticide exposure estimates would increase the power of

epidemiological studies to detect such an association if one exists.

Methods: Categories of pesticide use

were identified from the tasks reported in a previous community-based

case–control study in Scotland. Typical pesticides used in each task in each

decade were identified from published scientific and grey literature and from

expert interviews, with the number of potential agents collapsed into 10 groups

of pesticides. A pesticide usage database was then created, using the task list

and the typical pesticide groups employed in those tasks across seven decades

spanning the period 1945–2005. Information about the method of application and

concentration of pesticides used in these tasks was then incorporated into the

database.

Results: A list was generated of 81

tasks involving pesticide exposure in Scotland covering seven decades producing

a total of 846 task per pesticide per decade combinations. A Task-Exposure

Matrix for PESTicides (TEMPEST) was produced by two occupational hygienists who

quantified the likely probability and intensity of inhalation and dermal

exposures for each pesticide group for a given use during each decade.

Conclusions: TEMPEST provides a basis

for assessing exposures to specific pesticide groups in Scotland covering the

period 1945–2005. The methods used to develop TEMPEST could be used in a

retrospective assessment of occupational exposure to pesticides for ish

epidemiological studies or adapted for use in other countries.

Further details of TEMPEST can be found

on the IOM website.
