“…The measured values for K som-c were similar to values reported for pristine soils ( , ), suggesting that the use of solvent extraction to obtain a “clean” soil did not give soil organic matter with unusual desorption properties. The soils were from disturbed industrial sites and consisted mainly of subsoil; therefore, the content of aliphatic extractable material would have been low prior to contamination.…”

Bioremediation changes the quantity and nature of the contaminant matrix remaining in soil, because some compounds are selectively degraded while others remain undegraded. It was hypothesized that changes to the contaminant matrix may alter the chemical and physical properties of the soil, such that subsequent desorption of a specific PAH compound would be altered. Desorption of [14C]naphthalene from two creosote-contaminated soils was measured before and after bioremediation. Although the bioremediation treatment removed the lower-molecular weight components, increasing the average molecular weight of the residual creosote by 10−36%, partition coefficients based on the mass of organic carbon in the soil were unaffected. Partition coefficients for naphthalene in soil organic matter were 4.6−8.3 times smaller than in the creosote contaminant. When partitioning was modeled as the sum of the contributions of the nonaqueous phase contaminant and the soil organic matter, the partition coefficients for the creosote contaminant were in the range 3500−4040 mL/g of organic carbon, for both soils with and without bioremediation. The insensitivity of partition coefficients to creosote source and to bioremediation suggest that sorption of naphthalene to a residual creosote matrix was relatively insensitive to detailed composition of the creosote.

“…Good correlations have been reported between TOC and PAHs in some soils (Jones et al, 1989a; Pignatello and Xing, 1996; Wilcke and Zech, 1997; Pignatello, 1998). In other cases, PAHs have also been observed to be correlated to BC (McGroddy and Farrington, 1995; Gustafsson et al, 1997; Jonker and Smedes, 2000; Dachs and Eisenreich, 2000), low‐density particles (Prahl and Carpenter, 1983), and soil type (Kishi et al, 1990; Pichler et al, 1996; Jonker and Smedes, 2000). According to these previous studies, the relationship between PAH concentrations, TOC, BC, sulfur, and soil type has also been examined in Tenerife Island.…”

Polycyclic Aromatic Hydrocarbons in Mountain Soils of the Subtropical Atlantic

Surface soil samples from various altitudes on Tenerife Island, ranging from sea level up to 3400 m above mean sea level, were analyzed to study the distribution of 26 polycyclic aromatic hydrocarbons (PAHs) in a remote subtropical area. The stable atmospheric conditions in this island define three vertically stratified layers: marine boundary, trade-wind inversion, and free troposphere. Total PAH concentrations, 1.9 to 6000 microg/kg dry wt., were high when compared with those in tropical areas and in a similar range to those in temperate areas. In the marine boundary layer, fluoranthene (Fla), pyrene (Pyr), benz [a]anthracene (BaA), and chrysene (C + T) were largely dominant. The predominance of Fla over Pyr may reflect photo-oxidative processes during atmospheric transport, although coal combustion inputs cannot be excluded. The PAHs found in higher concentration in the soils from the inversion layer were benzo[b + j]fluoranthene (BbjF) + benzo[k]fluoranthene (BkF) > benzo[e]pyrene (BeP) approximately indeno[1,2, 3-cd]pyrene (Ind) > benzo[a]pyrene (BaP) approximately benzo[ghi]perylene (Bghi) > coronene (Cor) approximately dibenz[a,h]anthracene (Dib), reflecting that high temperatures and insolation prevent the accumulation of PAHs more volatile than BbjF in significant amounts. These climatic conditions involve a process of standardization that prevents the identification of specific PAH sources such as traffic, forest fires, or industrial inputs. Only soils with high total organic carbon (TOC) (e.g., 10-30%) preserve the more volatile compounds such as phenanthrene (Phe), methylphenanthrenes (MPhe), dimethylphenanthrenes (DMPhe), and retene (Ret). However, no relation between PAHs and soil TOC and black carbon (BC) was found. The specific PAH distributions of the free tropospheric region suggest a direct input from pyrolytic processes related to the volcanic emission of gases in Teide.

“…1 and 2). Comparison of literature data on chlorophenols [63], chlorobenzenes [64,65], and naphthalene and acenaphthene [65-671 showed that the calculated values may be lower as well as higher than experimentally derived values. The difference is generally no more than a factor of five.…”

The toxicity of 76 priority pollutants to lettuce (Luctuca sutiva) was determined in soil and in nutrient solution. In the first case a static and in the latter a semistatic exposure was established. Volatile and easily degradable compounds had high EC50 values in soil (>1,000 kg/g). In nutrient solution, however, several of these compounds were rather toxic. Quantitative structureactivity relationships (QSARs) relating EC50 values to log KO, could be described for the toxicity in nutrient solution. Generally, the toxicity of the compounds increased with increasing lipophilicity. Deviations were (partly) caused by reactivity (N-containing compounds, double bonds in compounds), low lipophilicity (log KO, values < l), and EC50 values close to solubility. To relate toxicity in soil and nutrient solution, soil EC50 values were recalculated to values in the soil pore water using calculated adsorption coefficients. Estimated pore-water EC50 values showed a good correlation with values determined in nutrient solution but were not equal to these values. The differences can be attributed to differences in exposure (static vs. semistatic).
