A SURVEY OF EPA OPP AND OPEN LITERATURE DATA ON SELECTED PESTICIDE CHEMICALS TESTED FOR MUTAGENICITY .1. INTRODUCTION AND 1ST 10 CHEMICALS/

Parties interested in registering a pesticide chemical with the U.S. E nvironmental Protection Agency's (USEPA's) Office of Pesticide Program s (OPP) must submit toxicity information to support the registration. Mutagenicity data are a part of the required information that must be submitted. This information is available to the public via Freedom of Information requests to the OPP. However, it is felt that this informa tion would be more effectively and widely disseminated if presented in a published medium. Beginning with this publication, sets of mutageni city data on pesticide chemicals will be periodically published in the Genetic Activity Profile (GAP) format. In addition, mutagenicity data extracted from the currently available open literature is also presen ted to provide a more complete database and to allow comparisons betwe en the OPP-submitted data and other publicly available information.
