| Summary: | River sediment contamination is a cause of decline in water quality which brings a
detrimental effect on aquatic ecosystems and human life. The purpose of this study
is to determine the existence and pollution level of PAEs compound in the
Sembrong River sediments. Sembrong River is chosen because the river has
evidence from previous studies to contain heavy metals and other pollutants.
Sediment samples were collected using core sediment sampler at 3 different
locations along the river banks. Laboratory tests were conducted to determine the
concentration phthalate esters compounds in Sembrong River sediments. Results
showed that the concentrations of PAEs are in the range of 0.01-15.63 mglkg. Di-nbutyl
phthalate (DBP), and di-(2-ethylhexyl) phthalate (DEHP) are the highest
concentration of compounds found in the sediment. Other PAEs detected in the
sediment of Sembrong River are dimethyl phthalate (DMP), diethyl phthalate
(DEP), benzyl butyl phthalate (BBP), and di-n-octyl phthalate (DNOP)
