“…[303][304][305][306][307][308][309][310][311] Indeed, the total contaminant thickness in our experiments was greater during the winter (February) than the fall (October) transmitting from the substrate to the water molecules. 237 Applying this concept to MoS 2 and assuming van der Waals interactions dominate, it is reasonable to conclude that a contaminant layer 0.50 nm thick will block a significant amount of the attractive forces originating from the substrate (i.e., bulk MoS 2 ).…”

Polycyclic aromatic hydrocarbons (PAHs) were measured in two wetland plant species grown outdoors in pots of sediment contaminated with up to 730,000 μg/kg total PAHs. After approximately 3 months, the plants were harvested, cleaned, and analyzed for an expanded suite of PAHs which included both the 16 priority PAHs and 22 alkyl PAH homologs. Sediment and air samples were also collected and analyzed. PAH compounds were detected in all of the samples, with the highest concentrations in the contaminated sediment. The root sample concentrations were generally about one order of magnitude lower than that of the sediment, and were strongly correlated with the concentration in the sediment in which they were grown. The concentrations in foliage were much lower and did not correlate with sediment concentration. Concentrations of low molecular weight PAH compounds detected in the foliage were not significantly lower in plants grown in control sediments, suggesting that the sediment is not the primary source of these PAHs. Several high molecular weight PAHs were detected only in plants grown in contaminated sediment. Plants of both species grown in control sediment were larger than plants grown in contaminated sediment.

“…Despite soil can contribute to leaf pollutant concentrations, some HMs are accumulated in the roots and scarcely translocated to the aboveground plant portion (Domínguez et al 2011) whereas PAHs are negligibly absorbed by roots (Simonich and Hites 1995). The aim of this paper was to test the correspondence between an a priori subdivision of sites of Campania Region (Southern Italy) in three typologies (remote, periurban, and urban) on the basis of human management and the concentrations of HMs (Cd, Cr, Fe, and Pb) and PAHs (benzo[a]pyrene, chrysene, fluoranthene, and phenanthrene) in leaves of Quercus ilex L., a typical Mediterranean tree, widely employed as biomonitors (Alfani et al 2000;De Nicola et al 2005. In addition, this paper aimed to evaluate, through the leaf analyses, temporal trends of the inorganic and organic pollutants over a long period (approximately 20 years for HMs and 10 years for PAHs).…”

Concentrations of four heavy metals (HMs) (Cd, Cr, Fe, Pb) and four polycyclic aromatic hydrocarbons (PAHs) (fluoranthene, phenanthrene, chrysene, benzo[a]pyrene) in Quercus ilex L. leaves collected at the Campania Region (Southern Italy) in previous air biomonitoring studies were employed to (1) test the correspondence with an a priori site subdivision (remote, periurban, and urban) and (2) evaluate long temporal trends of HM (approximately 20 years) and PAH (approximately 10 years) air contaminations. Overall, Q. ilex leaf HM and PAH concentrations resulted along the gradient: remote < periurban < urban sites, reflecting the a priori subdivision based on human management. Over a long time, although a clear decrease of leaf Pb, chrysene, fluoranthene, and phenanthrene concentrations occurred at the urban sites, a high contamination level persists.
