“…PAHs are hydrocarbons consisting of two or more aromatic rings joined to form a single structure (Fetzer, 2000). The US Environment Protection Agency (USEPA) has a list of PAHs, which are described as 16 priority pollutants and referred to as PAH 16 (see Table 26.1).…”

“…Ex-situ methods based on solid-phase extraction [8,9] followed by gas chromatography (GC) or liquid chromatography (LC) mass spectrometry (MS) [10][11][12][13][14] are the most widely adopted methods for both quantitative and quantitative analysis of PAHs. Although, high sensitivity and specificity can be achieved using these GC/LC-MS-based methods, considerable time is required for sample pre-concentration and pretreatment; the sample must also be transported to the laboratory for analysis [15][16][17][18]. Ambient ionization methods [19][20][21][22][23] are well suited for portable mass spectrometers [24][25][26][27] as vacuum requirements are reduced.…”

Abstract. Desorption atmospheric pressure chemical ionization (DAPCI) is implemented on a portable mass spectrometer and applied to the direct detection of polycyclic aromatic hydrocarbons (PAHs) and alkyl substituted benzenes. The presence of these compounds in the environment poses a significant threat to the health of both humans and wildlife because of their carcinogenic, toxic, and mutagenic properties. As such, instant detection outside of the laboratory is of particular importance to allow in-situ measurement at the source. Using a rapid, high throughput, miniature, handheld mass spectrometer, several alkyl substituted benzenes and PAHs (i.e., 1,2,3,5-tetramethylbenzene, pentamethylbenzene, hexamethylbenzene, fluoranthene, anthracene, benzo[k]fluoranthene, dibenz [a,h]anthracene, acenaphthene, indeno [1,2,3-c,d]pyrene, 9-ethylfluorene, and 1-benzyl-3-methyl-naphthalene) were identified and characterized using tandem mass spectrometry (MS/MS) from ambient surfaces, in the open air. This method can provide almost instantaneous information while minimizing sample preparation, which is advantageous in terms of both cost and simplicity of analysis. This MS-based technique is applicable to a wide range of environmental organic molecules.

“…Ikhajiagbe and Anoliefo (2011) reported that WEO pollution becomes widespread when they are carried by run-off during rainfall to nearby farms. The concentration of PAHs in lubricating oil increases with time of usage and those with two and three rings accumulate rapidly in used lubricating oil to very high levels (Vwioko and Fashemi, 2005 (Fetzer, 2000), they can cause a reduction in the level of available plant nutrients and a rise to a toxic level of elements such as manganese.…”

This study investigated the heavy metal content and microbial composition of rhizosphere of Panicum maximum obtained from some auto mechanic workshops in Benin City, Nigeria. The grass was uprooted and soil sample was taken from its rhizosphere. The sample were labeled appropriately and immediately transported into a polythene bag covered with aluminium foil papers. It was then taken to the laboratory for heavy metals and microbial assay. The results showed that average plant density of Panicum maximum per 100m 2 of sampled subplots in the mechanic workshops was 8.50 in Ikpoba-Okha and 9
