Abstract

Tallo estuary is a catchment area river ecosystem is the most affected by aquatic pollution due to a major role of the river for community.A study on water quality, heavy metal concentration and microalgae abundance at selected sites of Tallo River Estuary was carried out. The aim of this research are: 1) Determine distribution and concentration of existing heavy metal at ecosystem of Tallo River Estuary, 2) Identify microalgae dominant from Tallo River Estuary ecosystem where have been polluted by several type of heavy metal.

The results showed that there were three heavy metals at Tallo River Estuary which have a high concentration and above permissible maximum concentration of environment quality standard, such as Lead (Pb), Copper (Cu) and Chromium (Cr). Statistical result showed that there was a significant different in heavy metal concentration between the sampling stations. Concentration of all heavy metals measured was higher at sediment than in the water column.

Skeletonema sp, Nitzchia sp and Synedra sp were abundance at all sites of the research location. However, there was a strong correlation and significant different between concentration of Chromium in the water and Skeletonema sp and Synedra sp.
