“…Then, both quantitative analysis of naphthalene and qualitative analyses of final products were carried out with the method of EPA 8270 D by gas chromatography-mass spectrometry (Agilent 7890B GC & 5977A MSD) coupled with HP-5MS column (30 m Â 0.25 mm Â 0.25 μm, Agilent). The working conditions of column and GC-MS instrument were reported in previous study (Argun et al 2020). Linearity of the method was determined by using calibration curve of naphthalene which was prepared at the six different concentration in the range of 0.05-50 μg/L (Figure 2).…”

“…Increased industrial activity has resulted in the release of a wide variety of PAHs to the environment. Naphthalene and anthracene have been reported as the most common detected PAH compounds in wastewaters (Argun et al 2020;Nas et al 2020). Naphthalene used as an intermediate in the manufacture of azo dyes, phthalic anhydride, surfactants, and pesticides has been caused an increase in naphthalene concentration in nature (Mangal 2020).…”

“…Another routes of movement to the aquatic medium of naphthalene are known as rain and runoff waters (Irwin 1997) due to the naphthalene can transfer between air and water depending on its' solubility and environmental conditions. Also, anaerobic degradation of some organic matters can lead to the PAH formation (Argun et al 2020;Nas et al 2020). Therefore, naphthalene was detected in high levels (0.01-15 μg/L) in many aquatic environments (Staples et al 1985;Kalmykova et al 2014;Oturan et al 2015;Ates & Argun 2018;Argun et al 2020).…”

All living creatures are exposed to naphthalene direct (inhalation, ingestion, and dermal contact, oral) or indirectly (food chain).…”

In this study, the fate of naphthalene was investigated with a supercritical water oxidation process (SCWO). Also, the effectiveness of different operating conditions including pressure, temperature, residence time and oxidant dose on the formation of by-products were determined. The experimental sets were determined by the experimental design program and the effect of the selected variables on the removal of the naphthalene was associated statistically. According to obtained results, naphthalene by SCWO process was mineralized up to 98.5%. Removal efficiencies in sub- and supercritical conditions were determined as between 94 and 100%. Derivatives of aldehyde, propanoic acid, benzene acetic acid and benzofuran were detected as by-products at many experimental conditions and also, some intermediates with a molecular weight higher than naphthalene were determined.

“…The authors (Deng M. et al, 2018) investigated that the heavy metals concentrations in wastewater were within the limits of official discharge standards. Basic biological treatment plays a secondary role (Argun M. et al, 2020). During the study of leachates, landfills are characterized as sources of intense pollution, including a high concentration of macro-and micro-pollutants (Adelopo A. et al, 2020).…”

The tourism industry is concentrated within the boundaries of the Subcarpathia Forestry District of Ukraine. These are mostly resort complexes with recreation houses, hotels and restaurants. Since the issue of solid household waste processing has not been resolved in Ukraine, landfills are emerging near recreation facilities. Undoubtedly, such a situation contradicts the improvement processes, because landfills are objects of detonation of dangerous substances and compounds infiltrating into all components of the environment due to geochemical flows. The object of the conducted research was determination of chemical elements in the newly formed substrates on the surface of the following landfills, i.e. Bronytskyi, Stryiskyi, Boryslavskyi, which are located not far from the border with Poland within the tourist and recreational complex of the Lviv region of Ukraine, geographically belonging to the Subcarpathia Forestry District of Ukraine. It was established that the chemical elements of the toxic group and biogenic elements accumulate. The traces of individual elements were also determined. The Bronytskyi landfill is the most polluted with the following chemical elements: Pb (3.56-4.06 mg/kg), Zn (2.84-3.67 mg/kg), Gd (0.021-0.033 mg/kg), P (457.3-609.7 mg/kg), K (9.7-14.6 mg/kg), Ca (174.7-237.7 mg/kg), Ga (3.58-5,98 mg/kg), La (1.09-1.24 mg/kg), Y (0.013-0.014 mg/kg), Cd (0.15-0.176 mg/kg), Sn (0.013-0.018 mg/kg), Nd (0.029-0.046 mg/kg), Eu (0.022-0.036 mg/kg) and Th (0.05-0.078 mg/kg). The site of the Boryslav landfill is most polluted in the western side -Fe (16.06-19.72 mg/kg), Cu (0.37-0.43 mg/kg), Gd (0.003 mg/kg), Si (43-58.2 mg/kg), P (782.4-995.5 mg/kg), Ca (88.6-104.7 mg/kg), Mn (1.7-2.7 mg/kg), Sc (0.009 mg/kg), Cr (1.069-1.255 mg/kg), Y (0.015-0.016 mg/kg), Nd (0.016-0.018 mg/kg). In the eastern side of the Stryi landfill the presence of the following elements is most evident -Fe (18.98-27.97 mg/kg), Ni (0.09-0.21 mg/kg), Zn (0.14-0.19 mg/ kg), Pb (0.05-0.1 mg/kg), Al (1.6-2.0 mg/kg), P (718.1-652.5 mg/kg), Mn (2.5-3.5 mg/kg), Ga (0.01 mg/kg), La (0.02-0.04 mg/kg), Cr (0.009-0.013 mg/kg), Ge (0.214-0.551 mg/ kg), Cd (0.014-0.02 mg/kg), Nd (0.017-0.037 mg/kg), Th (0.009-0.016 mg/kg). Such a detailed chemical analysis for the presented research objects was carried out for the first time. Determining of the chemical content of the newly formed substrate is important from the point of view of environmental protection solutions implementation.
