This dataset presents baseline and policy scenario projections for plastic leakage to aquatic environments, at the global level for the 2019-2060 period. The dataset provides projections for accumulated stocks both in oceans and in rivers and lakes, as well as leakage to water from mismanaged...

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...

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 report examines the progress made in water management in OECD countries in the light of the objectives of Agenda 21. It presents the experience of the OECD programme of environmental performance reviews and focuses on issues of sustainable use of water resources, pollution control and water...

This report draws on the water management chapters of 42 country reviews carried out to date to identify common achievements and remaining challenges for OECD countries in terms of further reducing the pollution burden and protecting human health and aquatic ecosystems. Conclusions are drawn...

After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, that is disperse pollution from surface runoff, soil filtration and atmospheric...
