LONG-TERM INVESTIGATIONS ON CHEMICAL AND MICROBIAL CHANGES OF A SLIGHTLY OIL POLLUTED BEACH1

摘要: ABSTRACT A sandy and muddy beach polluted by Arabian light crude oil in 1974 was investigated 1974, 1975, 1981. The shift of the hydrocarbon contamination from sand to mud has been determined infrared spectroscopy glass capillary gas chromatography. In 14 months, mean values content declined 203 milligrams per liter (mg/l) 10 mg/l. However, those flat increased 300 percent (from 37 mg/l 108 mg/l). Six years later, fossil fuel concentration had decreased 0.6 8 for beach, respectively. Nevertheless, both areas still reflect former polluting event. This established definitively trace analysis acyclic isoprenoid alkanes (norpristane, pristane, phytane) which indicates detection mature diastereoisomers. bacteria fate hydrocarbons. numbers degraders rapidly several orders magnitude...
