Abstract

The acute toxicity of a Malaysian crude oil to red snapper, Lutjanus argentimaculatus, black
tiger shrimp and Penaeus monodon were investigated. The animals were exposed to water soluble
fractions (WSF) of crude oil in a flow-through bioassay system and the toxicants were analyzed by gas
chromatography (GC) and gas chromatography and mass spectrometer (GC-MS). The 96 h LC50 values
of the WSF of crude oil for fish and shrimp were 3.24 ± 0.21 and 8.52 ± 0.89 ppm of WSF of crude oil,
respectively. In this investigation, the fish were more sensitive to crude oil than the shrimp, with respect
to the similarity in their habitations.
