in the pesticides (28) listed in this table (29) (30) | Pesticides | not applicable | not applicable | 0,2 (30) | | | | | | | (1) CAS: Chemical Abstracts Service. (2) EU number: European Inventory of Existing Commercial Substances (EINECS) or European List of Notified Chemical Substances (ELINCS). (3) This parameter is the EQS expressed as an annual average value (AA-EQS). Unless otherwise specified, it applies to the total concentration of all substances and isomers. (4) Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies. (5) This parameter is the EQS expressed as a maximum allowable concentration (MAC EQS). Unless otherwise specified, it applies to the total concentration of all substances and isomers. Where the MAC EQS are marked as “not applicable”, the AA EQS values are considered protective against short-term pollution peaks in continuous discharges since they are significantly lower than the values derived on the basis of acute toxicity. (6) If an EQS for biota or sediment is given, it, rather than the water EQS, shall be applied, without prejudice to Article 3(3) of this Directive allowing an alternative biota taxon, or another matrix, to be monitored instead, as long as the EQS applied provides an equivalent level of protection. Unless otherwise specified, it applies to the total concentration of all substances and isomers. Unless otherwise indicated, the biota EQS relate to fish. “fw fish” indicates the biota EQS for freshwater fish monitored in inland waters; “sw fish” indicates the biota EQS for saltwater fish monitored in other surface waters. For substances numbered 15 (Fluoranthene), 28 (PAHs), and 51 (Bisphenol-A) the biota EQS refers to crustaceans and molluscs. For the purpose of assessing chemical status, monitoring of Fluoranthene PAHs, and Bisphenol-A in fish is not appropriate. For substance number 37 (Dioxins and dioxin-like compounds), the biota EQS relates to fish, crustaceans and molluscs, in line with point 4.1.5 of Annex I to Commission Regulation (EU) 2023/915 (*). (7) For the group of priority substances covered by brominated diphenylethers (No 5), the EQS refer to the sum of the concentrations of congener numbers 28, 47, 99, 100, 153 and 154. (8) Tetra, Penta, Hexa, Hepta, Octa and Decabromodiphenylether (CAS numbers 40088-47-9, 32534-81-9, 36483-60-0, 68928-80-3, 32536-52-0, 1163-19-5, respectively). (9) 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). (10) No indicative parameter is provided for this group of substances. The indicative parameter(s) shall be defined through the analytical method. (11) DDT total comprises the sum of the isomers 1,1,1 trichloro 2,2 bis (p chlorophenyl) ethane (CAS 50 29 3, EU 200 024 3); 1,1,1 trichloro 2 (o chlorophenyl) 2 (p chlorophenyl) ethane (CAS 789 02 6, EU 212 332 5); 1,1-dichloro 2,2 bis (p chlorophenyl) ethylene (CAS 72 55 9, EU 200 784 6); and 1,1 dichloro 2,2 bis (p chlorophenyl) ethane (CAS 72 54 8, EU 200 783 0). (12) These EQS refer to bioavailable concentrations of the substances. (13) Nonylphenol (CAS 25154-52-3, EU 246-672-0) including isomers 4-nonylphenol (CAS 104-40-5, EU 203-199-4) and 4-nonylphenol (branched) (CAS 84852-15-3, EU 284-325-5). (14) Octylphenol (CAS 1806-26-4, EU 217-302-5) including isomer 4-(1,1’,3,3’-tetramethylbutyl)-phenol (CAS 140-66-9, EU 205-426-2). (15) Benzo(a)pyrene (CAS 50-32-8) (RPF 1), benzo(b)fluoranthene (CAS 205-99-2) (RPF 0,1 ), benzo(k)fluoranthene (CAS 207-08-9) (RPF 0,1 ), benzo(g,h,i)perylene (CAS 191-24-2) (RPF 0), indeno(1,2,3-cd)pyrene (CAS 193-39-5) (RPF 0,1 ), chrysene (CAS 218-01-9) (RPF 0,01 ), benzo(a)anthracene (CAS 56-55-3) (RPF 0,1 ), dibenz(a,h)anthracene (CAS 53-70-3) (RPF 1) and fluoranthene (CAS 206-44-0) (RPF 0,01 ). Fluoranthene also appears separately in row 15. The PAHs anthracene and naphthalene are listed only separately because no RPF is available. (16) For the group of polyaromatic hydrocarbons (PAHs) (No 28), the biota EQS refers to the sum of the concentrations of eight of the nine PAHs listed in footnote 15 expressed as benzo(a)pyrene equivalents based on the carcinogenic potencies of the substances relative to that of benzo(a)pyrene, i.e. the RPFs in footnote 15. Benzo(g,h,i)perylene does not need to be measured in biota for the purposes of determining compliance with the overall biota EQS. The biota EQS for fluoranthene in row 15 must also be complied with. (17) Tributyltin compounds including tributyltin-cation (CAS 36643-28-4). (18) Sediment EQS. (19) There is insufficient information available to set a MAC-EQS for these substances.
