Water Quality Assessment using Benthic Macroinvertebrates in Wetlands and Ponds: Preliminary Study Case of Jijia and Miletin Ponds (ROSPA0042)

摘要

Water quality assessment as a expression for environment quality (biotic integrity or degradation) for wetlands, channels, lakes and ponds is attended at Jijia and Miletin Ponds with 1052 ha aquatic surfaces. The preliminary results for six months sampling period (October 2010-Avril 2011) for B-IBI revealed good biotic integrity, in all our study stations (Larga Jijia Pond - 32,80; Vladeni Pond - 41,12; Halceni Dam Lake -43,61 and Miletin River - 31), slightly divergent from least disturbed condition. The saprobic index for macroinvertebrates and chlorophyll 'a' values results revealed the IIIrd quality class. The regime of dissolved oxygen, oxygen saturation, CBO_5 and nutrients - orthophosphate, nitrite, nitrate - indicated a good quality, with moderate organic load.
