daily and seasonal dynamics
important factor for many chemical and biological processes
estimation of biological activity (also eutrophication)
indicator for organic pollution (oxygen consumption)
daily and seasonal dynamics
important factor for many chemical and biological processes
important factor for the solubility of oxygen in water
indicator for impacts of cooling water
daily and seasonal dynamics
indcator for buffering capacity (depending on the geological circumstances in the catchment)
indicator for industrial contamination
important factor for many chemical and biological processes,
e.g. ammonium-ammonia-equilibrium or bonding/mobilisation effects of pollutants like heavy metals
indicator for the geological circumstances in the catchment e.g. (high conductivity in coquina regions)
clue for industrial impacts
cause of eutrophication
important indicator for diffuse pollution by fertilizers (wash-out by interflow)
indicator for the efficiency of sewage plants
important clue for punctual sources (sewage plants, combined sewer overflows)
as minimum factor a main cause of eutrophication
important indicator for differentiation of diffuse and punctual sources (difference between total-P and ortho-P)
indicator for organic pollution by surface flow and erosion
evidence for punctual sources (sewage plants, combined sewer overflows)
impact of particles via erosion and from point sources
documents the composition of the biocoenosis
indicator for eutrophicating processes
bonding/mobilisation effects of pollutants like heavy metals in the sediment
indicator for the self-purification capacity
