Biodegradation Tests

Biodegradation is the decomposition of organic contaminants by microbial organisms into smaller compounds and is a beneficial process for the natural reduction of contaminants that may be released to the environment. 

We use the following test methods:

275-Day Closed Bottle Biodegradation Test (ISO 11734-1995), EPA Method 1647

      This method determines degradation of base fluids by monitoring gas production due to         microbial degradation of the test fluid in marine sediment.

​

OECD 301D - Biodegradation Closed Bottle Test

      This method is applicable for determining if a chemical has the potential to biodegrade in

      a freshwater environment.  It is a respirometry test that measures aerobic

      biodegradation by dissolved oxygen.

​

OECD 306 - Biodegradation Closed Bottle Test Saltwater

     This method is applicable for determining if a chemical has the potential to biodegrade in

     natural seawater.  It is a respirometry test that measures aerobic biodegradation by

     dissolved oxygen.
