The OECD Secretariat received almost simultaneously three proposals for an OECD Test Guideline on Direct Phototransformation in Water, i.e. aqueous photolysis. The purpose of this Guidance Document is to situate these proposals in a broad context consisting of the basic concepts of...

This OECD Emission Scenario Document (ESD) provides information on the sources, use patterns and release pathways of chemicals used in the treatment of water in a number of areas to assist in the estimation of releases of chemicals to the environment.

This dataset presents trends in plastic leakage to aquatic environments, for the 15 global regions of the OECD ENV-Linkages model for the 1990-2019 period. The dataset includes leakage to aquatic environments from mismanaged waste and litter, transport of plastics leakage to oceans and...

This Test guideline describes studies on phototransformation in water to determine the potential effects of solar irradiation on chemicals in surface water, considering direct photolysis only. It is designed as a tiered approach. The Tier 1 is based on a theoretical screen. The rate of decline...
