Estimation of the background(threshold) total petroleum hydrocarbon concentration and analysis of the characteristics of petroleum hydrocarbon contamination in a certain oilfield in Northeast China

Based on 68 surface soil samples and 50 drilling soil samples which were obtained from a field survey in June 2010,the total petroleum hydrocarbon(TPH) background(threshold) concentration is determined using the Cumulative Probability Plots,and is compared with those of the monitoring cross section method.TPH characteristics of surface soil in different land-uses of the study area and longitudinal section soils in the contaminated sites are also analyzed with the available data.The soil TPH degr...
