EPA Method 835.2130:
Hydrolysis as a Function of pH and Temperature

Summary:
The majority of the earth?s surface is covered by water in the form of oceans, seas, rivers, lakes, streams, or ponds. As a result, chemical substances or mixtures released to the environment are likely to enter aqueous media and could undergo transformation via hydrolysis. Hydrolysis represents the transformation of a chemical substance by reaction with water into new chemicals different from their precursors. Certain classes of these substances, upon entering aquatic media, can undergo hydrolysis, which is one of the most common chemical reactions controlling stability and is, therefore, one of the principal chemical transformation pathways of these substances in the environment.

Scope:
This guideline is intended to meet testing requirements of both the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) (7 U.S.C. 136, et seq.) and the Toxic Substances Control Act (TSCA) (15 U.S.C. 2601).
