“…This sample volume is small compared to other methods for the detection of PAHs. 4,5,41 This is the least required sample volume and in practice, this small volume might not be an advantage since it needs a precise volume measurement tool. However, it is important from the environmental point of view.…”

“…3 Hence, the identification and monitoring of PAHs is a worldwide concern. [2][3][4][5][6][7][8] PAHs are detected by high performance liquid chromatography (HPLC), 6,7 gas chromatography-mass spectrometry (GC-MS), 9,10 atmospheric pressure gas chromatography, 11,12 and different spectroscopies. 3,[13][14][15][16] These methods are sensi-tive and accurate, but are expensive and plagued by long analysis time, limiting their application, 17 in the field.…”

To investigate intraspecific variations of foliar uptake of polycyclic aromatic hydrocarbons (PAHs) of winter wheat (Triticum aestivum L.), leaves of six varieties including Changwu 521 (CW), Hedong TX-006 (HD), Jiaomai 266 (JM), Xiaoyan 22 (XY), Yunong 949 (YN), and Zhongmai 175 (ZM) were exposed to three levels of (0, 0.25, and 1.5 mg L) mixture of six selected PAHs (phenanthrene, anthracene, pyrene, benz[a]anthracene, benzo[a]pyrene, and benzo[g,h,i]perylene). After 10 consecutive days of application, all the six selected PAHs (Σ PAHs) were determined in the leaves of the six varieties of the winter wheat. There were apparent intraspecific differences in foliar uptake of PAHs in the winter wheat. The highest concentrations of Σ PAHs in the leaves of YN variety (64.6 mg kg) were approximate two times of the lowest concentrations in the leaves of HD variety (29.6 mg kg). Both individual PAHs and Σ PAHs in the cuticular waxes were significantly (p < 0.01) higher than those in leaves and far higher than those in roots, indicating that the cuticular waxes could play significant role in foliar uptake of PAHs. The present results also showed that the concentrations PAHs in leaves were positively (p < 0.05) correlated with the water solubility of the six selected PAHs. In addition, the present study suggested that there was basipetal translocation of PAHs in the winter wheat after foliar application of PAHs, although the mechanism was yet to be further studied.

Plant leaves play a key role in the accumulation of PAHs, as they are able to capture PAHs from the air. In this paper, the mechanism, including absorption and adsorption, for plants to scavenge PAHs from the air was reviewed. Moreover, the differences of PAHs accumulating capability are mainly compared among three representative plant species, including pine needles, Holm oak leaves, and moss. On the whole, it is shown that oak leaves present the strongest PAHs accumulating capability for total PAHs among three plants species. Oak leaves and pine needles show higher accumulating tendency for light and medium molecular weight PAHs, whereas moss presents stronger accumulating tendency for heavy molecular weight PAHs. Environmental factors (i.e., temperature, seasonality, and photolysis) also account for the process of PAHs transferred from air to plants. With the temperature climbing, the concentration of PAHs in the air will increase. Due to the meteorological conditions and the human activities changed with seasons, it was shown that the PAHs were greatly accumulated in leaf surface in winter than in summer. Photolysis was also able to influence the PAHs on leaf surface, which are significant to this process. In conclusion, oak, pine, and moss can be used to filter PAHs when considering urban landscaping. Besides combining the traditional analytical methods with in situ determination, there might be able to provide a novel method to further study the specific absorption mechanisms. The accumulation of PAHs in crop leaf surface related to the application of surfactants is also worth studying.
