Abstract

The aims of this study were to determine the content of total petroleum hydrocarbon (TPH) and heavy metals in top soil at Wonocolo public crude oil mining. Three composite soil samples were collected from oil well (OW), refinery (R), and transportation line (T) areas. Quantification and identification of TPH were performed by Gravimetric method and Gas Chromatography-Mass Spectrometry (GC-MS), respectively. Heavy metals concentrations were analyzed using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). The results showed that each soil samples contained C 14-36 of TPH with high concentration of 8.33; 12.30; and 4.35% in OW, R, and T soils, respectively. These values exceeded the limit of soil standard of 1.00% that indicated the top soils at Wonocolo public crude oil mining were highly polluted by TPH. Meanwhile, heavy metals such as Pb, Cr, and Hg have been detected in OW, R, and T soil at of 0.07-0.10, 0.02-0.03, and 0.05-0.06 mg/g, respectively. These values were below the soil quality standard and indexed as moderate-very severe contamination of heavy metal. Bioremediation may be recommended to reduce and manage the TPH pollution levels.
