Guidance on Environmental Risk Assessment for
Pesticide Registration - Part 8: Soil organisms
1 Scope
This Part specifies the principles, procedures and methods for risk assessment of the
impacts of pesticides on soil organisms.
This Part is applicable to the risk assessment of the impact on soil organisms for the
pesticide registration of chemical pesticide and the biological source with clear
chemical structures of active ingredients.

4 Basic Rules
The risk assessment of pesticides to soil organisms shall follow the following principles:
a) This Part is a risk assessment based on the protection of soil organisms. It
focuses on related soil organisms that are susceptible to pesticides. According
to the principles of sensitivity to pesticides, ecological value, and attention, it
attaches great importance on the ecological value and function of soils it
represents. In conjunction with management objectives, the purpose of risk
assessment is to ensure the survival and reproduction of important soil
organisms, soil ecological values and functions shall not be affected, or only
temporarily affected, so as to ensure the sustainability of soil resources in the
soil ecosystem.
b) The risk assessment of pesticides to soil organisms adopts a hierarchical
assessment method, and the risk is characterized by risk quotient (RQ).
5 Assessment Procedures and Methods
5.1 Overview
The risk assessment process of pesticides to soil organism environment is performed
in accordance with Figure A.1 of Appendix A.
5.2 Problem description
5.2.1 Risk estimation
Determine the possibility for exposure of soil organisms according to the pesticide use
methods. When soil organisms cannot be excluded from pesticide exposure according
to the method of use, a risk assessment shall be performed. When major metabolites
of pesticides are present, and toxicity data of major metabolites on soil organisms are
available, risk assessments shall be performed for major metabolites.
For pesticides used in multiple crops or multiple control objects, when the dosing
method, amount or frequency of dosing, and dosing time for each crop or control object
are diff......
