Estimation of detergent influx and impact assessment in freshwaters

, : Estimation of detergent influx and impact assessment in freshwaters. Science of the Total Environment 136(3): 301-318

An equation is derived which rigorously defines the partitioning of inorganic carbon flux into alkali addition, calcium precipitation, production and respiration in fresh waters, polluted by the influx of detergents. The model has been extended to account for the modulation of oxygen concentration due to the oxygen demand of detergents (ODD). The equation is applied to two such polluted systems receiving detergent influx in the range of 50-285 g m-3 (as calcium carbonate equivalent). The flux in the various parameters has been compared with unpolluted systems and with laboratory simulation studies, to assess the impact of detergents. Given certain assumptions, the influx can be visualized in the form of an environmental stress, reducing productivity. The degree of reduction varies with the loading of the system.
