“…Numerous studies have indicated that agricultural soils and vegetables have been contaminated by toxic pollutants (Gao et al, 2005). Some investigators have found that toxic pollutants such as heavy metals (Hu and Ding, 2009), polycyclic aromatic hydrocarbons (PAHs) (Yin et al, 2008), persistent organic pollutants (POPs) (Gao et al, 2005), organochlorine pesticides (Tao et al, 2005) and PAEs are present in suburban agricultural soils (Chen et al, 2011;Xia et al, 2011;Kong et al, 2012). PAEs are among the most abundant semi-volatile organic chemicals found in Chinese soils .…”

a b s t r a c tThe concentrations of six priority phthalic acid esters (PAEs) in intensively managed suburban vegetable soils in Nanjing, east China, were analyzed using gas chromatographyemass spectrometry (GCeMS). The total PAE concentrations in the soils ranged widely from 0.15 to 9.68 mg kg À1 with a median value of 1.70 mg kg À1 , and di-n-butyl phthalate (DnBP), bis-(2-ethylhexyl) phthalate (DEHP) and di-n-octyl phthalate (DnOP) were the most abundant phthalate esters. Soil PAE concentrations depended on the mode of use of plastic film in which PAEs were incorporated as plasticizing agents and both the plastic film and poultry manure appeared to be important sources of soil PAEs. Vegetables in rotation with flooded rice led to lower concentrations of PAEs in soil. The results indicate that agricultural plastic film can be an important source of soil PAE contamination and further research is required to fully elucidate the mechanisms of PAE contamination of intensive agricultural soils with different use modes of use of plastic film.Crown

“…These compounds are believed to accumulate in soils for many years because of their persistence and hydrophobicity (Ping et al 2007). Thus, soil is an important sink for PAHs in the environment (Yin et al 2008). Cousins et al (1999) claimed that evaporation, leaching, and migration of PAHs in soils are possible sources of atmospheric and groundwater contamination.…”

A total of 46 surface soil samples collected from the experimental area, buffer area, and core area of the Yellow River Delta Natural Reserve (YRDNR), China, and an adjacent area outside the reserve were analyzed for 23 PAHs including highly carcinogenic dibenzopyrene isomers. The total concentrations ranged from 87.2 to 319 ng/g for ∑23PAHs and 79.2 to 311 ng/g for ∑16PAHs with average concentrations of 133 and 119 ng/g, respectively. Pearson correlation analysis implied that the total polycyclic aromatic compound (PAH) concentrations had a significant positive correlation with the total organic carbon content on the condition that four sites with abnormal values were removed. Low molecular-weight 2- to 3-ring PAHs predominated in the present study. Source diagnostics based on PAHs isomer ratios, principal component analysis, and multiple linear regression suggested that petroleum contributed most to the PAH contamination in the YRDNR, whereas a potential toxicity assessment using BaPeq indicated that the four dibenzopyrenes were the major carcinogenic PAH contributors in the area under investigation, although their concentrations only represented a small proportion of the total PAH concentrations.

“…For cactus stem were DaA, Bghi, Pyr, Cry, BaA, Fla, BaP, Ind, Ant and Phe in dry season and BaA, Fla, DaA, Pyr, Bghi and Ant in wet season. In wet season in both crops were high concentrations of PAHs we supposed a diminished by effect of washing but the irregular rains in Mexico City (low content of water and spread out) only causes drop of suspended particles in atmosphere in long time of wet season It is recognized that the low molecular weight PAHs (two and some three rings) are common in fresh fuels, but also in combustion activities and in some industrial emissions, indicating mostly petrogenic origins, four-ring PAHs (and also some three-ring) are linked with motorized traffic in general and diesel consumption in particular and the high molecular weight PAHs (five and six rings) denote the existence of heavy machine or industrial activities (Yin et al, 2008;Wang et al, 2009) There routes of PAHs in plants such as take up from soil via the roots or from air via the foliage; uptake rates are dependent on the concentration, solubility, and molecular weight of the PAH and on the plant species (ATSDR, 1995). Some plants have been used to monitor atmospheric deposition of PAHs, example, mosses, lichens and vegetables.…”
