Study on the Effect of Sewage Pollutant of Bandar Imam Petrochemical Company on Benthic Macrofauna Community Mossa Creek Using Biodiversity Indices and Bioindicators
M. Sh. Fazeli
Macro benthoses are an important part of sea-bed fauna
which include Polycheata, Decapoda and Mollusca.
Some species of this group are considered as biological indicators for
aquatic ecosystem. Macro benthos are mostly inhabitants without migration
and they can be used as indexes of ecological crises related to water.
In the present research, benthic community structure in Ghanam creek and
region of Mossa creek, is located around BIPC sewage outlet were studied,
eight station were selected and water and sediment samples were collected
in two season warm (September) and cold (February). Result of research
indicated that station of sewage outlet around had least species and higher
organic matter, on the contrary, the station far from petrochemical industry
(station located in Ghanam creek) activities had higher species diversity.
Also, present study showed that Polychaetes, reference of pollution bioindicators
had higher abundance. Consequently, macro benthic biodiversity relation
with dissolved oxyqen and percentage of organic matter in the sediment.
