“…Among the several pollutants present in water, polycyclic aromatic hydrocarbons (PAHs) have received particular attention in the last years, because of their carcinogenicity and persistency in the environment. [1][2][3][4] PAHs are a class of hazardous treatment plants, [2,3,13] the most commonly applied methods are based on physicochemical processes, including photodegradation, oxidation, coagulation, and sorption. [2][3][4]6,7] However, current treatments involving advanced oxidation and ozonation processes are affected by the formation of partial oxidized by-products which, in several cases, are more toxic than the parent molecules.…”

“…[2,3] These compounds are characterized by high hydrophobicity and good lipid solubility due to their aromatic and delocalized structure: when their molecular weight increases, their aqueous solubility diminishes, whereas resistance to oxidation and reduction rises. [2][3][4] PAHs absorption and bioaccumulation in several tissues, as well as their ubiquitous occurrence in the environment, pushed US EPA (United States Environmental Protection Agency) and EEA (European Environment Agency) to identify 24 PAH compounds as priority contaminants, thus introducing strict regulations for their monitoring.

organic compounds made of two or more aromatic rings, fused together in linear, angular, or cluster arrangements. They can be also referred as low-molecular weight PAHs (two or three rings) and high-molecular weight PAHs (four or more rings). [3] These ubiquitous compounds can be generated from both anthropogenic activities, such as industrial, residential, and vehicular emissions, and natural pheno mena, i.e., open burning, volcanic activities, and spills from coal deposits. [2,3,[5][6][7] The occurrence of PAHs has been assessed worldwide in different aquatic systems including influents and effluents from wastewater treatment plants, groundwater, surfaceand sea-water. [3] Currently, over 400 PAHs and derivatives have been identified and classified, but most regulations, analyses, and data are focused on only 14 to 20 PAH compounds. [2,3,7] PAHs are well-known toxic, mutagenic, either carcinogenic or suspected carcinogenic compounds, accumulating in human and animal tissues. [2,3] These compounds are characterized by high hydrophobicity and good lipid solubility due to their aromatic and delocalized structure: when their molecular weight increases, their aqueous solubility diminishes, whereas resistance to oxidation and reduction rises.

The European Union has set the maximum limit of 0.1 µg L −1 as sum of benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[ghi]perylene, and indeno [1,2,3-cd] pyrene in water for human consumption, with a particular attention to benzo[a]pyrene limited to 0.01 µg L −1 . [12] The removal of PAHs represents one of the current challenges in environmental chemistry. Methods are based on biodegradation, chemical, and physical removal processes, often combined in order to obtain the highest degree of PAHs removal.

In this study, the ambient persistent organic pollutants (POPs) such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) concentrations were measured for 12 months at urban and semi-urban areas using the passive air sampler. During the sampling period, a total of 14 PAH (∑14PAH) concentrations measured in urban and semi-urban areas were found as 54.4 ± 22.6 ng/m3 and 51.7 ± 34.3 ng/m3, respectively. Molecular diagnostic ratios (MDRs) were used to determine PAH sources. According to the MDR values, combustion sources are the most important PAH sources in both sampling areas. However, since the urban area is close to the industrial zone, the combustion sources occurred at high temperatures (> 800 oC), while the semi-urban area generally consisted of burning petrogenic fuels. ∑50PCB concentrations measured in the urban and semi-urban areas were found as 522.5 ± 196.9 pg/m3 and 439.5 ± 166.6 pg/m3, respectively. Homologous group distributions were used to determine the source of PCBs. According to homologous group distributions, Tri-, Tetra-, and Penta- chlorinated PCBs were dominant in both sampling areas. ∑10OCP concentrations measured in urban and semi-urban areas were found as 242.5 ± 104.6 pg/m3 and 275.9 ± 130.9 pg/m3, respectively. Also, α-HCH/γ-HCH and β-/(α + γ)-HCH ratios were used to determine the source of OCPs. Lindane was the predominated OCP in both sampling areas.

Separation of 1‐Naphthol from Wastewater Using HF‐Free Microwave‐Assisted Synthesized MIL‐101(Cr): Kinetics, Thermodynamics and Reusability Studies**

Microwave-assisted synthesis of Chromium (III) Terephthalate Metal Organic Framework, MIL-101(Cr), was achieved in an aqueous media in the absence of hydrofluoric acid (HF). The synthesized material was characterized using Fourier transform infrared spectroscopy, powder X-ray diffraction, nitrogen adsorption/desorption isotherms and field emission scanning electron microscope. Results indicate that the synthesized MIL-101(Cr) using microwave irradiation poses higher surface area than those obtained using autoclave in a conventional oven method. Adsorptive removal of 1-naphthol from aqueous solution using synthesized MIL-101(Cr) was evaluated at various temperatures and concentrations. The Langmuir and Freundlich isotherms are used to describe the adsorption equilibrium behavior. The pseudo-second order and intraparticle kinetic models were applied to understand the rate limiting step and the mechanism of 1-naphthol adsorption. The thermodynamic analysis of solid-liquid system was investigated. The synthesized MIL-101(Cr) showed higher 1-naphthol adsorption capacity, compared to other adsorbents like biochar and multiwall carbon nanotube.
