Biomonitoring of polycyclic aromatic hydrocarbons and synthetic musk compounds with Masson pine (Pinus massoniana L.) needles in Shanghai, China

Method development for gas chromatography‐tandem mass spectrometry analysis of trace level polycyclicaromatic hydrocarbons, alkyl polycyclicaromatic hydrocarbons, polychlorinated biphenyls, and organochlorinepesticides in pine needle specimen

“…Total PAHs were detected in a concentration range of 135.18-411.39 μg/kg. Overall, the total concentrations in the most samples were similar or below the values presented in literature for pine needles, 13,14,[17][18][19][20][21][22]24,25,32 but was higher than those presented in certain literature, 15,23 when no source specific data were compared. Table 1 compares the concentration of total PAHs detected in pine needles in this study with the results of other previous studies.…”

“…PAHs have often been measured in pine needles to track various contaminants and pollutant migration routes. Gas chromatography (GC)-mass spectrometry (MS) methods [13][14][15][16][17][18][19][20][21][22][23][24] and high-performance liquid chromatography-fluorescence detection (HPLC-FLD) 25 have been mainly used to measure PAHs in pine needles. Ultrasonic solvent extraction (USE), 13,[16][17][18]20,23 soxhlet extraction, 14,19,22,24 shaking extraction, 15 and accelerated solvent extraction (ASE) 21 have been used for the extraction of PAHs from pine needles.…”

Although these methods use a large amount of sample, the detection limit is high and the extraction and purification processes are complicated.…”

Photosynthetic pigments content in the urban habitat herbaceous plants leaves under the volatile organic compounds effect

“…Depending on the dose of effect they can cause allergic reactions in humans and animals, hypoxia, reduction of blood capillary tone, neurotoxic action and suppress soil biota. The study of volatile organic compounds effect on the activity intensity of the plants photosynthetic apparatus, on the one hand, is little studied when compared to the effect of oxides of nitrogen, carbon, sulphur, ammonia, particulate, heavy metals and microplastics [1][2][3][4][5][6][7][8][9][10][11], on the other hand, it is relevant in order to compare the their toxicity level to the parameters of plants life activity [12][13][14][15][16][17]. It is necessary to find and develop new methods for evaluating open air pollution by volatile organic compounds due to the current changes in the structure of industrial production.…”

“…Xylols are able to inhibit algae growth, and their activity can be enhanced in the presence of solid particles. Benz(a)pyrene, like some other polyarenes, is highly toxic, capable of transboundary transfer, biological transformation, accumulation in natural objects and has a mutagenic property [12,13,20].…”
