“…Immediately collected insects were sorted by naked eyes and some of them placed in plastic labeled vials with 70% ethyl alcohol, then taken to taxonomy laboratory for identification using taxonomic keys (Badawy et al,;2013Degabriele, 2013. While the bulk of selected insects is freezed for heavy metal analysis and biochemical studies.…”

This investigation was aimed to evaluate water pollution with heavy metals using three biomarkers, as well as the study of the aquatic insects-seasons interaction. Three species of aquatic insects collected from El-Mansouriya stream (Dakahlia, Egypt), during the different seasons from spring 2014 to winter 2015. Water samples, sediments and whole body of the three aquatic insects were analyzed for heavy metal contents. As well as, two enzyme biomarkers, Acetylcholinesterase (AChE) and glutathione-S-transferase (GST) were used to monitor aquatic insects' response to water pollutants. Results showed various activities of the three biomarkers at the different studied seasons. Where, the concentration of selected heavy metals, in the whole body of the three insects, showed a relatively wide range for each metal analyzed. Also, higher values of metal pollution index (MPI) were attained in hotter seasons (spring and summer) and its decrements were observable during cooler seasons (autumn, winter), that provides a representative picture to the environmental state of environmental impacts on the aquatic ecosystem. While the heavy metals were found to be highly accumulated in selected aquatic insects body, as well as the variation of enzymes activity, thus both enzymes could be used as biomarker of water and sediment contamination.

“…The SP3 downstream station has high H' and ASPT, with moderates taxa richness and Chironomidae. The high value of H', ASPT and taxa richness was characterized by the absent of pollutant materials, especially anorganic or toxic materials, while the moderate value of Chironomidae shows relatively low organic pollutant [6,30,33,34,39,40]. It can be said that the water in observed station has been slightly polluted by organic matter.…”

The aim of research is to monitor the water quality of some ecotourism sites along Prafi Rivers (Manokwari, West Papua) using macrozoobenthic biotic index, Prati's index and some chemical-physical factors of water. Research was done from July to September 2016. Sampling was performed through Purposive Random Sampling. Macrozoobenthic was collected from each sampling sites in three locations, (upstream, middle stream, downstream) using Surber net and hand net. Water quality was categorized based on Implicit Prati's Pollution index that is derived from DO, BOD5, pH, nitrate, orthophosphate, and water temperature values. Macrozoobenthic data was used to analyze the diversity index and six biotic indices. Result of the study showed that DO, BOD5, pH and nitrate value in all location meet the standard quality for water based on PP. no 82, 2001 class II (fisheries, recreation, animals husbandry, and irrigation). The turbidity value in sites of upstream, middle stream and downstream Subsay and SP3 have made the standard water quality according to WHO for drinking water (<5 NTU). Based on the Prati's index, the water quality was ranging from excellent to acceptable categories with value 0.4-1.9. The taxa richness of macrozoobenthic was 31 taxa. The Shannonwiener diversity index in all stations were more than 2, indicated that the water was not polluted. The water quality of all station showed very excellent up to moderates (based on FBI), very excellent up to very bad (HBI), and excellent up to less polluted (ASPT). Percentage of Ephemeroptera, Plecoptera, and Trichoptera (% EPT) in all station up to 50% (excellent), except in station SP3 upstream (40%). EPT richness value in all station excellent to moderate. It can be concluded that the water quality of Subsay in upstream, middle stream, downstream and downstream of SP3 was excellent. The middle stream of SP3 and middle stream of SP1 has moderate quality, while the water quality in SP3 upstream, SP1 upstream and SPI downstream was bad.
