Risk Assessment Worksheets

Pesticide sprayingRisk assessment worksheets are a computational tool developed for the USDA Forest Service by Syracuse Environmental Research Associates, Inc. (SERA). These worksheets perform many of the calculations used in the Human Health Risk Assessments (HHRA) and Ecological Risk Assessments (ERA) prepared for many of the pesticides used by the Forest Service.


Worksheet Use

The basic idea of these worksheets is to isolate the computations from the discussions of the computations. The worksheets contain very little discussion and they are intended as a tool to make risk assessment calculations easier to understand and review. Pesticide Coordinators and other technical specialist familiar with HHRAs and ERAs can use these worksheets to develop risk values for the pesticide application rates and application scenarios specific to their particular pesticide project. The worksheets for the pesticides listed below, are presented in EXCEL format and can be downloaded for your use. The worksheets can be used to perform computer based project specific (site-specific) calculations that incorporate the characteristics of your project including chemical formulation, use rate, and site factors.

Documentation

Prior to using the worksheets, we recommend that you read the documentation provided for WorksheetMaker version 6.00.09 and the accomanying errata notes provided by SERA Inc. The documentation explains the organization of the worksheets, computation specifications, and other technical information. http://www.sera-inc.com/fsworksheetmaker.html

Support

Please note that SERA Inc. do not provide technical support for this product through telephone inquiries. If you have any questions about the worksheets, please contact the appropriate Regional Pesticide Coordinator in your region. For the pesticides Isoben, MCH and Verbenone, the worksheets available are in an earlier Version 2,04b, but will perform the same computations.
