This book is a summary of the presentations and discussions at the
Workshop on Methods of Pesticide Exposure Assessment held in Ottawa,
Canada, on October 5-8, 1993. The event was a joint effort of Health
Canada and the North Atlantic Treaty Organisation and was officially
supported by the United States Environmental Agency and the Organisation
for Economic Co-operation and Development (OECD). The goal of the
workshop was to examine current issues in the field of pesticide
exposure assessment with the aim of reaching an internationally
harmonized approach to methods of exposure assessment. With regulatory
agencies of OECD Member countries moving towards the harmonization of
data requirements, it was timely and beneficial to bring together
international experts in the field of pesticide exposure assessment to
discuss current issues. Approximately 60 delegates and 20 observers
participated, including individuals from 15 different countries
representing academia, government, industry and international
organizations. A guidance document on methods of pesticide exposure
assessment was presented as a means to achieving the goal of
international for critique and discussion harmonization. After extensive
discussion, the workshop delegates agreed in principle to procedures for
revising the guidance document. Following revision and further review by
a designated peer review group, the revised document will be submitted
to the OECD for consideration as a draft OECD Guidance Document on
pesticide exposure assessment methods. Both the revised and original
documents are included in these proceedings.
