“…To avoid these shortcomings, it is necessary to conduct a supplementary investigation and develop a conventional DLLME procedure for efficient extraction of PAHs from water samples. The combination of chlorinated solvents and conventional dispersive agents, such as acetone and acetonitrile, provides high extraction efficiency of individual PAHs, e.g., 96% for naphthalene group PAHs, 98% for PAHs with three and four aromatic rings and 95% for PAHs containing more than four aromatic rings [ 34 , 35 , 36 , 37 , 38 ]. However, the behavior of co-existing PAHs with diverse molecular weights in the extraction procedures with conventional solvents was not discussed in these works.…”

Polycyclic aromatic hydrocarbons (PAHs) are a class of persistent organic pollutants of water, and their determination at trace levels in the aquatic ecosystems is essential. In this work, an ultrasound-assisted dispersive liquid–liquid microextraction (DLLME) procedure was suggested utilizing a binary dispersive agent for recovery of different molecular weight polycyclic aromatic hydrocarbons (PAHs) from waters. The detection was carried out by gas chromatography–mass spectrometry (GC-MS) as well as high-performance liquid chromatography with fluorescence and diode-array detection (HPLC-FD/PDA). The method was optimized for the extraction of analytes with respect to the mixture composition, ratios of components, ultrasonication time and centrifugation parameters. The analytical schemes for PAHs extraction from water samples using different ratios of extraction and dispersive solvents are reported. The mixture consisting of chloroform and methanol was applied for the extraction of PAHs containing two or three fused aromatic rings; the mixture of chloroform and acetonitrile is suitable for PAHs containing more than four aromatic rings. The mixture of chloroform:acetone + acetonitrile was applied in the universal scheme and allowed for the simultaneous extraction of 20 PAHs with different structures. The developed sample preparation schemes were combined with GC-MS and HPLC-FD/PDA, which allowed us to determine the analytes at low concentrations (from 0.0002 µg/L) with the recoveries exceeding 80% and relative standard deviations of about 8%. The developed methods for the determination of 20 PAHs were applied to the analysis of water samples from the Karasun Lake (Krasnodar), Azov Sea (Temryuk) and Black Sea (Sochi).

“…The peaks 1-4 are prominent with UV detector while the remaining 12 PAHs have been observed using a fluorescence detector. Following that, unknown polyaromatic hydrocarbons from contaminated soil are extracted and compared to standard combinations to determine their identity [73,99]. The principle of interactions is used in donor-acceptor complex chromatography, in which the stationary phase (DACC column) functions as an electron acceptor, retaining the PAHs (electron donors) [104].…”

Human activity pollution has been shown to harm the environment, ecology, and health impacts. The polycyclic aromatic hydrocarbons (PAHs) produced by the industries such as tannery, distillery, pulp paper, and oil refineries are a major source of contaminant. PAHs are found all across the world, owing to long-term human pollution sources. PAHs' physico-chemical features, such as hydrophobicity and electrochemical stability, contribute to their environmental persistence and contribute to their carcinogenic and health effects. Numerous analytical and biological techniques for the qualitative and quantitative assessment of PAHs have been proposed. Bioaccumulation, adsorption, chemical oxidation, photolysis, volatilization, and microbiological degradation are the principal breakdown pathways of PAHs in the environment. Microbial populations, such as bacteria, fungi, and algae, play a crucial role in the biological elimination of PAHs. Oxidase, manganese peroxidases, lipases, and laccases are the enzymes involved in PAHs breakdown. The synthesis of surfactants by bacteria increases PAHs bioavailability and improves the elimination process of PAHs. Temperature, pH, aeration, moisture content, nutrition availability, absence of hazardous chemicals, and the kind and number of degrading microbial populations are all factors that influence PAHs decomposition. Microbial degradation mechanisms result in intermediate metabolites and carbon dioxide mineralization. The elimination of PAHs is improved by molecular approaches such as gene engineering and protein engineering. This review discussed the benefits of bioremediation strategies that were investigated for precise evaluation and were trusted at both the regulatory and scientific studies levels.

Due to food complexity and the low amount at which contaminants are usually present in food, their analytical determination can be particularly challenging. Conventional sample preparation methods making use of large solvent volumes and involving intensive sample manipulation can lead to sample contamination or losses of analytes. To overcome the disadvantages of conventional sample preparation, many researchers put their efforts toward the development of rapid and environmental-friendly methods, minimizing solvent consumption. In this context, microwave-assisted-extraction (MAE) has obtained, over the last years, increasing attention from analytical chemists and it has been successfully utilized for the extraction of various contaminants from different foods. In the first part of this review, an updated overview of the microwave-based extraction technique used for rapid and efficient extraction of organic contaminants from food is given. The principle of the technique, a description of available instrumentation, optimization of parameters affecting the extraction yield, as well as integrated techniques for further purification/enrichment prior to the analytical determination, are illustrated. In the second part of the review, the latest applications concerning the use of microwave energy for the determination of hydrocarbon contaminants—namely polycyclic aromatic hydrocarbons (PAHs) and mineral oil hydrocarbons (MOH)—are reported and critically overviewed and future trends are delineated.
