Polycyclic aromatic hydrocarbons in soils of a mountain valley: correlation with highway traffic and cancer incidence

Polycyclic aromatic hydrocarbons in highway plants and soils. Evidence for a local distillation effect

“…Since some PAH members are mutagenic, their presence in plant [1,[5][6][7] is of increasing concern because PAHs may ultimately be transferred to food. Moreover, the presence of PAHs in soils has been correlated with highway traffic and cancer incidence [8]. Nonetheless, despite several reports suggesting that airborne PAHs should be transferred over great distances [9][10], the mechanisms ruling atmospheric transfer are still poorly known.…”

Florida Cluster of Five Children with Endodermal Sinus Tumors

“…An association between polycyclic aromatic hydro carbons (from highway traffic) and cancer occurrence has been suggested [13]. The exposure of the cases to this form of pollution can probably be taken for gran ted due to the proximity of the highway.…”

Mass fragmentographic determination of polynuclear aromatic hydrocarbons in soil.

“…Blumer et al 1) have reported that polynuclear aromatic hydrocarbons can be Soxhlet-extracted, isolated by alumina column chromatography and determined by ultraviolet spectrophotometry and mass spectrometry. Windsor et al 2) have reported that polynuclear aromatic hydrocarbons can be fractionated by silicic acid column chromatography after Soxhlet-extraction, then identified and determined by a combination of gas chromatography and mass spectrometry.…”
