Assessment Of The Ecological Impacts Of Floriculture Industries Using Physico-chemical Parameters And Benthic Macroinvertebretes Metric Index Along Wedecha River Debrezeit Ethiopia
Wedecha River is one of floriculture industry sites in Debrezeit. Wedecha River is importantrnfor agriculture and domestic activities (eg, drinking, washing etc.) of the surrounding people.rnIt is exposed to waste water discharge of the floriculture industries and disturbance of thernaquatic ecosystem. Biological and chemical information was used to assess the quality ofrnwater and its impact on aquatic life and the ecology of the river. A total of 6 sites, onernreference site less impaired to represent natural conditions from upstream, and 5 impairedrnsites in the downstream were sampled for macroinvertebrates and physicochemicalrnparameters in the Wedecha River from November 2006 to May 2007 to assess the quality ofrnwater, ecology of the river and impact on aquatic life. Impaired sites data were compared tornreference conditions. Ten physicochemical parameters pH, TO, EC, COD, BOD5, S2-, SO4rn2-,rnPO4rn3-, NH3-N and NO3-N were used to assess their impact on river ecology and correlaternwith macroinvertabrates. There were significant differences in most of the Physicochemicalrnparameters (p
