Biodegradability test guidelines, table

Test guidelines are developed by various national and international organizations. Table 12.4 lists the OECD and U.S. Environmental Protection Agency (EPA) Office of Pollution Prevention and Toxics (OPPT) guidelines. It also lists experimental conditions, analytical methods, and criteria for whether a chemical is considered to be biodegradable (pass) and non-biodegradable (fail), when applicable.

The physical detergency and biodegradation characteristics of primary alcohols are affected by the carbon chain length distribution. Therefore each new supply may require testing to determine whether the desired properties in the chosen application can be achieved. Examples of guideline specifications are presented in Table 10.
