14 W A T E R Q U A L I T Y I N S L O V E N I A A surface water body has a good chemical status if: • any annual average value of parameters at a monitoring site does not exceed the prescribed limit value, • the time series of annual average values of any of the parameters whose concentration in the sediments has not had an upward trend in the last five-year period. Table 1: Limit values of parameters for the evaluation of the chemical status as listed in the Regulation on the chemical status of surface waters (7) GENERAL PHYSICO-CHEMICAL PARAMETERS PARAMETER UNIT water LIMIT VALUE sediment analysis Nitrate mg NO /L 3 25 Sulphate mg SO /L 4 150 PRIORITY LIST OF CHEMICAL STATUS PARAMETERS PARAMETER UNIT water LIMIT VALUE sediment analysis Cadmium µg Cd/L 1 yes 1,2 dichloroethane µg/L 10 Hexachlorobenzene µg/L 0.03 yes Hexachlorobutadiene µg/L 0.1 yes Hexachlorocyclohexane µg/L 0.05 yes Pentachlorophenol µg/L 1 yes Mercury µg Hg/L 1 yes Tetrachloroethene µg/L 10 Trichlorobenzene µg/L 0.4 yes Trichloroethene µg/L 10 Trichloromethane µg/L 12 INDICATIVE LIST OF PARAMETERS PARAMETER UNIT water LIMIT VALUE sediment analysis Copper µg Cu/L 5 Boron µg B/L 100 Zinc µg Zn/L 100 Chromium µg Cr/L 10 Nickel µg Ni/L 10 Lead µg Pb/L 10 Dichloromethane µg/L 10 Alachlor µg/L 0.1 Metolachlor µg/L 0.1 Atrazine µg/L 0.1 Simazine µg/L 0.1 Total pesticides µg/L 0.5 Anthracene µg/L 0.05 Naphthalene µg/L 1 PAH µg/L 0.1 Fluoranthene µg/L 0.025 Benzene µg/L 3.0 PCB µg/L 0.01 AOX µg Cl/L 20 EOX mg Cl/kg - yes Phenol substances (phenol index) µg/L 10 Mineral oils mg /L 0.05 Anion active detergents mg MBAS/L 0.10 PAH: Polycyclic aromatic hydrocarbons AOX: Adsorbable organic halogen compounds PCB: Polychlorinated biphenyls EOX: Extractable organic halogen compounds
Ledava, Čentiba Mura, Mota S U R F A C E W A T E R S Based on the results of the monitoring of river water quality in 2006, the chemical status of rivers was evaluated at 76 monitoring sites. A good chemical status was determined for 64 monitoring sites, and a bad chemical status was determined for 12 monitoring sites. The chemical status of rivers at individual monitoring sites in 2006 is shown in Map 1. A bad chemical status was determined on account of exceeding the limit values for adsorbable organic halogen compounds (AOX), metolachlor, atrazine, total pesticides, anion active detergents, mineral oils, boron and zinc. Monitoring sites for which a bad chemical status was determined in 2006 and the parameters exceeding the limit values are shown in Table 2. No characteristic trend was determined for concentrations of priority substances in sediments.
