Review of pollutants in petroleum refinery wastewaters and effect upon aquatic organisms
Abstract In the past decade, the number of organic chemical contaminants identified in oil refinery wastewaters has risen from less than 20 to over 300. This increase in knowledge was made possible by advances in gas chromatography-mass spectrometry instrumentation and new techniques to maximize resolution of capillary chromatography. The types of compounds identified in refinery wastewaters are similar to those identified in crude oils; i.e., aliphatic, aromatic, alkyl aromatic, polynuclear aromatic hydrocarbons, and some hydrocarbons containing nitrogen, sulfur, and oxygen. The contaminants in oil refinery wastewaters acutely lethal to aquatic organisms can be removed by biological treatment systems. However, biological treatment systems may not be capable of removing all deleterious contaminants. Long-term fathead minnow bioassays of biologically treated refinery wastewaters resulted in 10%–50% mortality after 14–16 days of exposure. The lethal effects were eliminated by sequential treatment with dual media filtration-activated carbon adsorption.
