Following a large blowout of crude oil in northern Italy in 1994, the distribution of polyaromatic hydrocarbons (PAHs) was examined over time and space in soils, uncultivated wild vegetation, insects, mice, and frogs in the area. Within 2 y of the blowout, PAH concentrations declined to background levels over much of the area where initial concentrations were within an order of magnitude above background, but had not declined to background in areas where starting concentrations exceeded background by two orders of magnitude. Octanol-water partitioning and extent of alkylation explained much of the variance in uptake of PAHs by plants and animals. Lower Kow PAHs and higher-alkylated PAHs had higher soil-to-biota accumulation factors (BSAFs) than did high-Kow and unalkylated forms. BSAFs for higher Kow PAHs were very low for plants, but much higher for animals, with frogs accumulating more of these compounds than other species.
