Notes
6 For Cadmium and its compounds (No 6) the EQS values vary depending on the hardness of the water as specified in five class categories (Class 1: < 40 mg CaCO3/l, Class 2: 40 to < 50 mg CaCO3/l, Class 3: 50 to < 100 mg CaCO3/l, Class 4: 100 to < 200 mg CaCO3/l and Class 5: ≥ 200 mg CaCO3/l).

12 Unless otherwise specified, the EQS parameter expressed as an annual average value (AA-EQS) applies to the total concentration of all isomers.

13 Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies.
