The QuEChERS method has been reported to be very adaptable with different matrices, samples sizes and extraction solvents and provides high analyte recoveries (Baduel et al, 2015;Cvetkovic et al, 2016;DeArmond et al, 2015).

“…Some of the key analytical methods mainly used in the analysis of PAHs and OH-PAHs in biological matrices include an extraction step such as soxhlet extraction (Cvetkovic et al, 2016), solid phase extraction (Baduel et al, 2015), and accelerated solvent extraction (Li et al, 2003) which is coupled to sample clean-up using a dispersive solid phase extraction (Baduel et al, 2015), gel permeation chromatography (Cloutier et al, 2017) or silica gel (Cvetkovic et al, 2016). However, these techniques are often time consuming and mainly use a large volume of chlorinated solvent for extraction.…”

However, the application of QuEChERS approach for the analysis of OH-PAHs is limited to a study on milk samples (Knobel et al, 2013) and rat brain tissue (Grova et al, 2011).…”

Health risk assessment of mixed contaminants: Interaction of metals on the uptake of polycyclic aromatic hydrocarbons in human liver cells

A key area of uncertainty in human health risk assessment of chemical mixtures is the application of additivity of dose or effects, which may overestimate or underestimate the actual risk. In this PhD thesis, interaction effects among mixtures of benzo [a]pyrene (B[a]P), pyrene (Pyr), phenanthrene (Phe) and naphthalene (Nap) in the presence or absence of arsenic (As), cadmium (Cd), lead (Pb) is elucidated for bioaccessibility, uptake (surrogate bioavailability) and metabolism of PAHs in human systems using in vitro models. A simulated human digestion based on the use of an in vitro model (Unified BARGE Method) was used to quantify PAH bioaccessibility from exposure to contaminated soils, whereas a human liver hepatocellular (HepG2) cell line (surrogate liver) was used as an in vitro model to quantify uptake and metabolism of PAHs. This PhD To investigate bioaccessibility of PAHs, seven chemically-variant top soils were collected from background sites in Australia and were spiked with PAHs and aged up to 90 days.The UBM results suggest that the most significant interactions between PAHs and soil components controlling its bioaccessibility was completed by the first 7 days of ageing condition of this study. It is noted that there was a significant lower bioaccessibility of Data from pure solution study suggests that uptake of PAHs and in the presence of As, Cd, and Pb in HepG2 cells generally showed less than additive effects among binary, ternary and seven compound mixtures of B[a]P, Pyr, Phe and Nap. Notably, the % uptake of Phe in HepG2 cells was found to decrease significantly in the seven compound mixture (p < 0.05) which had As, Cd and Pb. Using UBM-extracted solutions, interaction effects on uptake of PAHs in HepG2 cells was found to be both additive and less than additive.Moreover, the % uptake data from UBM-extracted real soil samples showed a decrease in % uptake of B[a]P, Pyr, Phe and Nap by 0.7 %, 1.8 %, 0.4 % and 0.04 %, respectively when compared to their individual PAH % uptake in HepG2 cells from exposure to UBMextracted spiked soil samples.Results of bioaccessibility, uptake and metabolism of B[a]P, Pyr, Phe and Nap as individual compounds or mixtures in the presence or absence of As, Cd and Pb provide significant new understanding towards interaction effects of these compounds in the context of human health risk assessment. For assessment of soils contaminated with PAHs and metal/loids, it clarifies situations where additive effects can be expected rather than assuming additivity as a general rule in risk assessment of chemical mixtures.4

Dyes have become common substances since they are employed in mostly all objects surrounding our daily activities such as clothing and upholstery. Based on the usage and disposal of these objects, the transfer of the dyes to other media such as soil and water increases their prevalence in our environment. However, this prevalence could help to solve crimes and pollution problems if detection techniques are proper. For that reason, the detection and characterization of dyes in complex matrices is important to determine the possible events leading to their deposition (natural degradation, attempts of removal, possible match with evidence, among others).Currently, there are several chromatographic and mass spectrometric approaches used for the identification of these organic molecules and their derivatives with high specificity and accuracy. This review presents current chromatographic and mass spectrometric methods that are used for the detection and characterization of disperse, acid, basic, and reactive dyes, and their derivatives.
