Publication on validation of a method to determine transformation of chemicals in manure
Manure is widely used as a fertilizer and applied to agricultural land. It may contain highly active chemicals like veterinary medicinal products or biocides, which enter the environment by this pathway. This is recognized by several regulatory frameworks, however, a detailed method for examining the transformation of chemicals in manure was lacking. The present publication describes the validation of a recently developed method for studying the anaerobic transformation of chemicals in pig and cattle liquid manure. Emphasis is placed on the validation ring test and the OECD process that led to the recent adoption of the method as OECD test guideline No. 320: ‘Determining anaerobic transformation of chemicals in liquid manure’.
