  "text": "‘ANNEX I\nENVIRONMENTAL QUALITY STANDARDS FOR PRIORITY SUBSTANCES AND CERTAIN OTHER POLLUTANTS\nPART A:\nENVIRONMENTAL QUALITY STANDARDS (EQS)\nAA annual average.\nMAC maximum allowable concentration.\nUnit [μg/l] for columns (4) to (7)\n[μg/kg wet weight] for column (8)\nCAS: Chemical Abstracts Service.\nThis parameter is the EQS expressed as an annual average value (AA-EQS). Unless otherwise specified, it applies to the total concentration of all isomers.\nInland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies.\nThis parameter is the EQS expressed as a maximum allowable concentration (MAC-EQS). 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.\nFor the group of priority substances covered by brominated diphenylethers (No 5), the EQS refers to the sum of the concentrations of congener numbers 28, 47, 99, 100, 153 and 154.\nFor 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).\nThis substance is not a priority substance but one of the other pollutants for which the EQS are identical to those laid down in the legislation that applied prior to 13 January 2009.\nNo indicative parameter is provided for this group of substances. The indicative parameter(s) must be defined through the analytical method.\nDDT total comprises the sum of the isomers 1,1,1-trichloro-2,2 bis (p-chlorophenyl) ethane (CAS number 50-29-3; EU number 200-024-3); 1,1,1-trichloro-2 (o-chlorophenyl)-2-(p-chlorophenyl) ethane (CAS number 789-02-6; EU Number 212-332-5); 1,1-dichloro-2,2 bis (p-chlorophenyl) ethylene (CAS number 72-55-9; EU Number 200-784-6); and 1,1-dichloro-2,2 bis (p-chlorophenyl) ethane (CAS number 72-54-8; EU Number 200-783-0).\nThere is insufficient information available to set a MAC-EQS for these substances.\nFor the group of priority substances of polyaromatic hydrocarbons (PAH) (No 28), the biota EQS and corresponding AA-EQS in water refer to the concentration of benzo(a)pyrene, on the toxicity of which they are based. Benzo(a)pyrene can be considered as a marker for the other PAHs, hence only benzo(a)pyrene needs to be monitored for comparison with the biota EQS or the corresponding AA-EQS in water.\nUnless otherwise indicated, the biota EQS relate to fish. An alternative biota taxon, or another matrix, may be monitored instead, as long as the EQS applied provides an equivalent level of protection. For substances numbered 15 (Fluoranthene) and 28 (PAHs), the biota EQS refers to crustaceans and molluscs. For the purpose of assessing chemical status, monitoring of Fluoranthene and PAHs 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 section 5.3 of the Annex to Commission Regulation (EU) No 1259/2011 of 2 December 2011 amending Regulation (EC) No 1881/2006 as regards maximum levels for dioxins, dioxin-like PCBs and non-dioxin-like PCBs in foodstuffs (OJ L 320, 3.12.2011, p. 18).\nThese EQS refer to bioavailable concentrations of the substances.\nPCDD: polychlorinated dibenzo-p-dioxins; PCDF: polychlorinated dibenzofurans; PCB-DL: dioxin-like polychlorinated biphenyls; TEQ: toxic equivalents according to the World Health Organisation 2005 Toxic Equivalence Factors.’\n(1)\n(2)\n(3)\n(4)\n(5)\n(6)\n(7)\n(8)\nNo\nName of substance\nCAS number\nAA-EQSInland surface waters\nAA-EQSOther surface waters\nMAC-EQSInland surface waters\nMAC-EQSOther surface waters\nEQSBiota\n(1)\nAlachlor\n15972-60-8\n0,3\n0,3\n0,7\n0,7\n(2)\nAnthracene\n120-12-7\n0,1\n0,1\n0,1\n0,1\n(3)\nAtrazine\n1912-24-9\n0,6\n0,6\n2,0\n2,0\n(4)\nBenzene\n71-43-2\n10\n8\n50\n50\n(5)\nBrominated diphenylethers\n32534-81-9\n0,14\n0,014\n0,0085\n(6)\nCadmium and its compounds\n(depending on water hardness classes)\n7440-43-9\n≤ 0,08 (Class 1)\n0,08 (Class 2)\n0,09 (Class 3)\n0,15 (Class 4)\n0,25 (Class 5)\n0,2\n≤ 0,45 (Class 1)\n0,45 (Class 2)\n0,6 (Class 3)\n0,9 (Class 4)\n1,5 (Class 5)\n≤ 0,45 (Class 1)\n0,45 (Class 2)\n0,6 (Class 3)\n0,9 (Class 4)\n1,5 (Class 5)\n(6a)\nCarbon-tetrachloride\n56-23-5\n12\n12\nnot applicable\nnot applicable\n(7)\nC10-13 Chloroalkanes\n85535-84-8\n0,4\n0,4\n1,4\n1,4\n(8)\nChlorfenvinphos\n470-90-6\n0,1\n0,1\n0,3\n0,3\n(9)\nChlorpyrifos (Chlorpyrifos-ethyl)\n2921-88-2\n0,03\n0,03\n0,1\n0,1\n(9a)\nCyclodiene pesticides:\nAldrin\nDieldrin\nEndrin\nIsodrin\n309-00-2\n60-57-1\n72-20-8\n465-73-6\nΣ = 0,01\nΣ = 0,005\nnot applicable\nnot applicable\n(9b)\nDDT total,\nnot applicable\n0,025\n0,025\nnot applicable\nnot applicable\npara-para-DDT\n50-29-3\n0,01\n0,01\nnot applicable\nnot applicable\n(10)\n1,2-Dichloroethane\n107-06-2\n10\n10\nnot applicable\nnot applicable\n(11)\nDichloromethane\n75-09-2\n20\n20\nnot applicable\nnot applicable\n(12)\nDi(2-ethylhexyl)-phthalate (DEHP)\n117-81-7\n1,3\n1,3\nnot applicable\nnot applicable\n(13)\nDiuron\n330-54-1\n0,2\n0,2\n1,8\n1,8\n(14)\nEndosulfan\n115-29-7\n0,005\n0,0005\n0,01\n0,004\n(15)\nFluoranthene\n206-44-0\n0,0063\n0,0063\n0,12\n0,12\n30\n(16)\nHexachloro-benzene\n118-74-1\n0,05\n0,05\n10\n(17)\nHexachloro-butadiene\n87-68-3\n0,6\n0,6\n55\n(18)\nHexachloro-cyclohexane\n608-73-1\n0,02\n0,002\n0,04\n0,02\n(19)\nIsoproturon\n34123-59-6\n0,3\n0,3\n1,0\n1,0\n(20)\nLead and its compounds\n7439-92-1\n1,2\n1,3\n14\n14\n(21)\nMercury and its compounds\n7439-97-6\n0,07\n0,07\n20\n(22)\nNaphthalene\n91-20-3\n2\n2\n130\n130\n(23)\nNickel and its compounds\n7440-02-0\n4\n8,6\n34\n34\n(24)\nNonylphenols\n(4-Nonylphenol)\n84852-15-3\n0,3\n0,3\n2,0\n2,0\n(25)\nOctylphenols\n((4-(1,1′,3,3′-tetramethylbutyl)-phenol))\n140-66-9\n0,1\n0,01\nnot applicable\nnot applicable\n(26)\nPentachloro-benzene\n608-93-5\n0,007\n0,0007\nnot applicable\nnot applicable\n(27)\nPentachloro-phenol\n87-86-5\n0,4\n0,4\n1\n1\n(28)\nPolyaromatic hydrocarbons (PAH)\nnot applicable\nnot applicable\nnot applicable\nnot applicable\nnot applicable\nBenzo(a)pyrene\n50-32-8\n1,7 × 10–4\n1,7 × 10–4\n0,27\n0,027\n5\nBenzo(b)fluor-anthene\n205-99-2\nsee footnote 11\nsee footnote 11\n0,017\n0,017\nsee footnote 11\nBenzo(k)fluor-anthene\n207-08-9\nsee footnote 11\nsee footnote 11\n0,017\n0,017\nsee footnote 11\nBenzo(g,h,i)-perylene\n191-24-2\nsee footnote 11\nsee footnote 11\n8,2 × 10–3\n8,2 × 10–4\nsee footnote 11\nIndeno(1,2,3-cd)-pyrene\n193-39-5\nsee footnote 11\nsee footnote 11\nnot applicable\nnot applicable\nsee footnote 11\n(29)\nSimazine\n122-34-9\n1\n1\n4\n4\n(29a)\nTetrachloro-ethylene\n127-18-4\n10\n10\nnot applicable\nnot applicable\n(29b)\nTrichloro-ethylene\n79-01-6\n10\n10\nnot applicable\nnot applicable\n(30)\nTributyltin compounds (Tributyltin-cation)\n36643-28-4\n0,0002\n0,0002\n0,0015\n0,0015\n(31)\nTrichloro-benzenes\n12002-48-1\n0,4\n0,4\nnot applicable\nnot applicable\n(32)\nTrichloro-methane\n67-66-3\n2,5\n2,5\nnot applicable\nnot applicable\n(33)\nTrifluralin\n1582-09-8\n0,03\n0,03\nnot applicable\nnot applicable\n(34)\nDicofol\n115-32-2\n1,3 × 10–3\n3,2 × 10–5\nnot applicable\nnot applicable\n33\n(35)\nPerfluorooctane sulfonic acid and its derivatives (PFOS)\n1763-23-1\n6,5 × 10–4\n1,3 × 10–4\n36\n7,2\n9,1\n(36)\nQuinoxyfen\n124495-18-7\n0,15\n0,015\n2,7\n0,54\n(37)\nDioxins and dioxin-like compounds\nSee footnote 10 in Annex X to Directive 2000/60/EC\nnot applicable\nnot applicable\nSum of PCDD+PCDF+PCB-DL\n0,0065 μg.kg–1 TEQ\n(38)\nAclonifen\n74070-46-5\n0,12\n0,012\n0,12\n0,012\n(39)\nBifenox\n42576-02-3\n0,012\n0,0012\n0,04\n0,004\n(40)\nCybutryne\n28159-98-0\n0,0025\n0,0025\n0,016\n0,016\n(41)\nCypermethrin\n52315-07-8\n8 × 10–5\n8 × 10–6\n6 × 10–4\n6 × 10–5\n(42)\nDichlorvos\n62-73-7\n6 × 10–4\n6 × 10–5\n7 × 10–4\n7 × 10–5\n(43)\nHexabromocyclododecane (HBCDD)\nSee footnote 12 in Annex X to Directive 2000/60/EC\n0,0016\n0,0008\n0,5\n0,05\n167\n(44)\nHeptachlor and heptachlor epoxide\n76-44-8/1024-57-3\n2 × 10–7\n1 × 10–8\n3 × 10–4\n3 × 10–5\n6,7 × 10–3\n(45)\nTerbutryn\n886-50-0\n0,065\n0,0065\n0,34\n0,034",
