Abstract
Regression analyses were conducted for prediction of benzo(a)pyrene (BaP) and total polycyclic aromatic hydrocarbons (PAHs) in soils. Dimensionless units were applied after each PAH was divided by naphthalene (Nap) for the regression analyses using a previously published Swiss data set or all data sets, including Chinese and Brazilian. A strong correlation was found between BaP/Nap ($R^2=0.95$) or ${\Sigma}PAH/Nap$ ($R^2=0.99$) and Pyr/Nap ratios from the Swiss data set. When the developed prediction equation was applied to other measurements to validate its accuracy, there was great agreement between the data and predicted values. This model could be used as a useful tool for the calculation of average BaP and ΣPAH in specific regions without additional tests.
