The Thermal Water Waste Pollution from Electricity Industry of PLTU - Tello and its Effects on Fishes and Macrozoobenthos Organism in Tallo Estuary, Makassar

Abstract: Study on thermal water waste pollution from electricity industry of PLTU - TELLO and its effects on fishes and macrozoobenthos in Tallo Estuary, Makassar has been conducted from March to May 2010. The result revealed that hot water caused increase temperature around the outlet of the factory. Direct observation demonstrated that difference temperature (?t) occurred along the river from outlet to the estuary. From the fifteen samples, it was observed that the mean of difference temperature (?t) in outlet were 5O C in the morning and 5.17O C in the day. In the Estuary the delta t (?t) were 4.7O C in the morning and 5.07O C in the day. It was also observed that the farther the distance from the outlet the cooler of the temperature was occurred. The mean of the delta t were 5.21OC in the morning and 5.20O C in the day. The increase of temperatures were followed by the decrease of dissolved oxygen, whereas the salinity increase by increasing the temperature. Fishes that caught in the study were 598. If the number converted to catch per unit trip per month, then the number was very small compared to the catching effort of the artisanal fisheries along the river bank of Tallo. Based on the macrozoobenthos data, the closer to the outlet, the fewer the number and the diversity of macrozoobenthos were found.
