DOC 006 – Relevance to Model Experiments to Photodegradation in The Environment

DOC 006 : Relevance to Model Experiments to Photodegredation in the Environment | October 1980

An ECETOC task force has reviewed the state of the art in photodegradation and is defining what work needs to be done to improve the methodology for assessing the photodegradation of chemicals in the environment. A definition of criteria for model experiments relevant to photodegradation in the environment, using artificial light, is proposed. Conditions of testing for water, soil and air photodegradations have been assessed and will be presented. The formerly proposed OECD test methods have been criticised in the light of these criteria and are considered unsuitable as official test methods. A derived methodology for aqueous photolysis is proposed in annex.
