Abstract: Study on the effects
of oil content on the macrozoobenthic community in thecoastal waters receiving
oil refinery effluents has been conducted. Samples ofwater and sediment were
collected in August 2006 from three stations in oilrefinery and one control
station in far distance from the oil refinery area. Waterquality parameters
measured in the present study were still in the tolerable levelfor the aquatic
biota. Oil content in the stations close to the oil refinery (10.17 -12.17 ppm
and 11.17 - 15.42 ppm) was higher than the control station (6.92 and6.17 ppm)
at high and low tide respectively. The abundance of macrozoobenthicat the
control station (333.23 id/m2) was higher that the oil refinery (151.50 -281.25
ind/m2). Simple linear regression showed that macrozoobenthic abundancewas
negatively correlated with oil content in the water column (Y = 431.92 -17.81
X; r = 0.64) and it was positively correlated with total organic matter in
thesediment (V = -174.55 + 27.23X: r = 0.69). This study showed that the oil
refineryand its related activities have significant contribution to the
elevated oil contentand the decreasing water quality which finally affect the
macrozoobenthiccommunity structure in the surrounding aquatic environments.
