Historical Dangerous Substances List I and List II
Data was collated annually until the end of 2011 for the Dangerous Substances Directive (76/464/EEC) on the discharge of dangerous substances to surface waters. The Dangerous Substances Directive was repealed in 2012 following the introduction of the Water Framework Directive (2000/60/EC), which includes monitoring and assessment of a wide range of chemicals in surface waters. List I covers substances that are particularly toxic or persistent, or may tend to accumulate in the environment. List II covers substances whose effects are less serious. List I includes 20 substances and List II has 67 substances. Every listed dangerous substance has a concentration limit known as an Environmental Quality Standard (EQS). The EQS is usually an upper concentration, with the exception of pH, which has both upper and lower limits. It is set for the receiving watercourse and not the discharge itself. The dangerous substance is not believed to be detrimental to aquatic life at any concentration below its EQS limit. The EQS varies for each substance and can be different for fresh, estuarine or coastal waters.
