SILENT WITNESS OF WATER POLLUTION: BIOINDICATOR FRESHWATER INVERTEBRATES

Abstract

During the last years, not only industrial activities, but also anthropogenic activities have had negative consequences for the freshwater ecosystems. All aquatic organisms accumulate organic or inorganic elements in their bodies whether or not these elements are essential to metabolism. Community compositions of freshwater invertebrates such as gastropods, oligochaetes and chironomids, reflect the states and changes in aquatic ecosystems. Many factors regulate the occurrence and distribution of these organisms. The most important of these factors are physical and chemical characteristics of water. Members of the invertebrates groups, due to their capacities to increase in number with increasing organic matter or to replace other benthic invertebrates that are less tolerant for a particular condition, have been universally applied on bioassessment  assays as indicators of the pollution in freshwater systems. Members of these groups can also show some taxonomic variations against polluters and many researchers may not know these variations and make mistake in identification using the existing identification keys.
