“…Although high molecular weight (HMW) carcinogenic PAHs, such as BbF, Chr, BaP, Inp, and BkF, were prevalent in samples from most sites, two low molecular weight (LMW) PAHs, Nap and Phe, were the dominant component in the soils from TBNA. These two LMWs accounted for 22.1% and 10.7%, respectively, of the PAHs concentration, which is close to the proportions in water and sediments from this area (Shi et al 2005). Normally, high molecular weight PAHs such as benzo[b + j + k]fluoranthene, Chr, Flu and Pyr are dominant in the soils investigated (Wilcke 2000).…”

“…Oil wells in TBNA are probably an important source of LMW PAHs, including Nap and Phe, and biological processes are probably another source of LMW PAHs, which will be further studied. It is well accepted that LMW PAHs predomination suggests either a local source of PAHs or a relatively recent introduction of these chemicals (Shi et al 2005).…”

“…The gross output of TBNA's industries reached 196 billion Yuan (about US $28.6 billion) in 2006, which was about 19 times of that in 1993. Reports have shown that PAHs are present in various environmental media in TBNA, and the highest concentration of PAHs in soil samples from TBNA exceeded 5,000 ng g −1 (Duan et al 2005;Shi et al 2005;Wu et al 2005); however, the industrial influence and regional difference in this area are unclear. There are three districts in TBNA from north to south: Hangu, Tanggu, and Dagang.…”

The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were determined by gas chromatography equipped with a mass spectrometry detector in 105 topsoil samples from an industrial area around Bohai Bay, Tianjin in the North of China. Results demonstrated that concentrations of PAHs in 104 soil samples from this area ranged from 68.7 to 5,590 ng g −1 dry weight with a mean of 16PAHs 814 ± 813 ng g −1 , which suggests that there exists mid to high levels of PAH contamination. The concentration of 16PAHs in one soil sample from Tianjin Port was exceptionally high (48,700 ng g −1 ). Ninetythree of the 105 soil samples were considered to be contaminated with PAHs (>200 ng g −1 ), and 25 were heavily polluted (>1,000 ng g −1 ). The sites with high PAHs concentration are mainly distrib- uted around chemical industry parks and near highways. Two low molecular weight PAHs, naphthalene and phenanthrene, were the dominant components in the soil samples, which accounted for 22.1% and 10.7% of the 16PAHs concentration, respectively. According to the observed molecular indices, house heating in winter, straw stalk combustion in open areas after harvest, and petroleum input were common sources of PAHs in this area, while factory discharge and vehicle exhaust were the major sources around chemical industrial parks and near highways. Biological processes were probably another main source of low molecular weight PAHs.

“…Soil contamination with PAHs and HMs in Tianjin is caused by long-term wastewater irrigation, sludge applications, solid waste disposal and automobiles exhaust [2]. According to Cao et al [14], the total PAH concentrations varied from 1800 to 35,000 ng L −1 in surface water and 227-600 ng L −1 in reclaimed water in Tianjin.…”

“…Polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs) are becoming increasingly prevalent in soil environments as a result of wastewater irrigation, sludge applications, solid waste disposal, automobiles exhaust and industrial activities [1,2]. In countries facing freshwater shortages, sewage water and industrial effluents are useful water sources that are commonly used for agricultural production.…”

Accumulation of polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs) by crop plants from contaminated soils may pose health risks. A greenhouse pot experiment using lettuce (Lactuca satuva L.) as a representative vegetable was conducted to assess the concentrations of PAHs and HMs in vegetables grown in wastewater-contaminated soils. The concentrations of total PAHs were ranged from 1.5 to 3.4 mg kg −1 in the contaminated soils, while 1.2 mg kg −1 in the reference soil. Linear regression analyses showed that the relationships between soil and shoot PAH concentrations were stronger for LMW-PAHs (R 2 between 0.51 and 0.92) than for HMW-PAHs (R 2 0.02 and 0.60), suggesting that translocation for LMW-PAHs is faster than HMW-PAHs. Furthermore, the data imply that root uptake was the main pathway for HMW-PAHs accumulation. The plant shoots were also highly contaminated with HMs, particularly Cd (0.4-0.9 mg kg −1 ), Cr (3.4-4.1 mg kg −1 ), Ni (11.7-15.1 mg kg −1 ) and Pb (2.3-5.3 mg kg −1 ), and exceed the guidance limits set by State Environmental Protection Administration (SEPA), China and the World Health Organization (WHO). This study highlights the potential health risks associated with cultivation and consumption of leafy vegetables on wastewater-contaminated soils.
