Abstract
A study was conducted to determine whether the sequestration of 21 polycyclic aromatic hydrocarbons (PAHs) in soil was correlated with their properties. From 22 to 58% of the PAHs was not extracted with n-butanol after their addition to soil. After 28 days of aging, the percentage of the PAHs remaining in the soil increased to 47–77%; however, nearly all of each compound was recovered by Soxhlet extraction. Correlations were based on the amounts of aged compound extracted with butanol. Properties of compounds used in the correlations included K ow, molecular length and molecular-connectivity indices (MCIs). No one property, including log K ow, resulted in an R 2 value greater than 0.26. A chain MCI ( 6χ ν CH) together with log K ow or a first-order MCI ( 1χ) resulted in R 2 values of 0.49 and 0.54, respectively. The data suggest that the properties tested are not important to predicting the sequestration of PAHs in soil.
