Ten pollutant phenols extracted from an oil refinery discharge, urban storm water and sewage effluent were analysed by gas chromatography-mass spectrometry. Recoveries varied from 43% to 97%, with a detection limit of 0.5 μg L-1. Concentrations ranged from below the detection limit up to 114.0μg L-1, the highest being in sewage effluent. The most common were phenol and cresol.
The effects of similar concentrations were determined in bioaccumulation experiments using the mussel Mytilus edulis and fish Trachurus novaezelandiae. Recoveries of phenols from tissues were 10-40%, with a detection limit of 0.5 ng g-1. 2,4-dimethylphenol, 2,4-dichlorophenol, 4-chloro, 3-methylphenol, 2,4,6-trichlorophenol and pentachlorophenol were accumulated, with bioconcentration factors ranging from 2.51 ± 0.51 for dimethylphenol to 283.8 ± 5.58 for pentachlorophenol; when placed in clean sea water, both species depurated all accumulated phenols to concentrations below detection within 24 h. Neither phenol nor cresol were accumulated.
Phenol and o-cresol inhibited the germination of Ulva lactuca gametes at concentrations above 1 mg L-1 (100 times the concentrations detected in the water samples).
Muscle and liver tissue from fish and invertebrates collected from the oil refinery discharge site in Botany Bay and control localities contained no detectable phenols.
