  "text": "Biological quality elements\nElement\nHigh status\nGood status\nModerate status\nPhytoplankton\nThe composition and abundance of phytoplanktonic taxa are consistent with undisturbed conditions.\nThe average phytoplankton biomass is consistent with the type-specific physico-chemical conditions and is not such as to significantly alter the type-specific transparency conditions.\nPlanktonic blooms occur at a frequency and intensity which is consistent with the type specific physico-chemical conditions.\nThe composition and abundance of phytoplanktonic taxa show slight signs of disturbance.\nThere are slight changes in biomass compared to type-specific conditions. Such changes do not indicate any accelerated growth of algae resulting in undesirable disturbance to the balance of organisms present in the water body or to the quality of the water.\nA slight increase in the frequency and intensity of the type-specific planktonic blooms may occur.\nThe composition and abundance of planktonic taxa show signs of moderate disturbance.\nAlgal biomass is substantially outside the range associated with type-specific conditions, and is such as to impact upon other biological quality elements.\nA moderate increase in the frequency and intensity of planktonic blooms may occur. Persistent blooms may occur during summer months.\nMacroalgae and angiosperms\nAll disturbance-sensitive macroalgal and angiosperm taxa associated with undisturbed conditions are present.\nThe levels of macroalgal cover and angiosperm abundance are consistent with undisturbed conditions.\nMost disturbance-sensitive macroalgal and angiosperm taxa associated with undisturbed conditions are present.\nThe level of macroalgal cover and angiosperm abundance show slight signs of disturbance.\nA moderate number of the disturbance-sensitive macroalgal and angiosperm taxa associated with undisturbed conditions are absent.\nMacroalgal cover and angiosperm abundance is moderately disturbed and may be such as to result in an undesirable disturbance to the balance of organisms present in the water body.\nBenthic invertebrate fauna\nThe level of diversity and abundance of invertebrate taxa is within the range normally associated with undisturbed conditions.\nAll the disturbance-sensitive taxa associated with undisturbed conditions are present.\nThe level of diversity and abundance of invertebrate taxa is slightly outside the range associated with the type-specific conditions.\nMost of the sensitive taxa of the type-specific communities are present.\nThe level of diversity and abundance of invertebrate taxa is moderately outside the range associated with the type-specific conditions.\nTaxa indicative of pollution are present.\nMany of the sensitive taxa of the type-specific communities are absent.\nHydromorphological quality elements\nElement\nHigh status\nGood status\nModerate status\nTidal regime\nThe freshwater flow regime and the direction and speed of dominant currents correspond totally or nearly totally to undisturbed conditions.\nConditions consistent with the achievement of the values specified above for the biological quality elements.\nConditions consistent with the achievement of the values specified above for the biological quality elements.\nMorphological conditions\nThe depth variation, structure and substrate of the coastal bed, and both the structure and condition of the inter-tidal zones correspond totally or nearly totally to the undisturbed conditions.\nConditions consistent with the achievement of the values specified above for the biological quality elements.\nConditions consistent with the achievement of the values specified above for the biological quality elements.\nPhysico-chemical quality elements\nThe following abbreviations are used: bgl = background level, EQS = environmental quality standard.\nApplication of the standards derived under this protocol shall not require reduction of pollutant concentrations below background levels: (EQS >bgl).\nElement\nHigh status\nGood status\nModerate status\nGeneral conditions\nThe physico-chemical elements correspond totally or nearly totally to undisturbed conditions.\nNutrient concentrations remain within the range normally associated with undisturbed conditions.\nTemperature, oxygen balance and transparency do not show signs of anthropogenic disturbance and remain within the ranges normally associated with undisturbed conditions.\nTemperature, oxygenation conditions and transparency do not reach levels outside the ranges established so as to ensure the functioning of the ecosystem and the achievement of the values specified above for the biological quality elements.\nNutrient concentrations do not exceed the levels established so as to ensure the functioning of the ecosystem and the achievement of the values specified above for the biological quality elements.\nConditions consistent with the achievement of the values specified above for the biological quality elements.\nSpecific synthetic pollutants\nConcentrations close to zero and at least below the limits of detection of the most advanced analytical techniques in general use.\nConcentrations not in excess of the standards set in accordance with the procedure detailed in section 1.2.6 without prejudice to Directive 91/414/EC and Directive 98/8/EC. (< EQS)\nConditions consistent with the achievement of the values specified above for the biological quality elements.\nSpecific non-synthetic pollutants\nConcentrations remain within the range normally associated with undisturbed conditions (background levels = bgl).\nConcentrations not in excess of the standards set in accordance with the procedure detailed in section 1.2.6 without prejudice to Directive 91/414/EC and Directive 98/8/EC.
