“…But with the progression of the reaction, a significant decrease in the concentration of both oxidant and organic matter was observed, resulting in a slowed conversion of organic matter. 35 Havva 36 studied the SCWO of polycyclic aromatic hydrocarbons (PAHs) in landfill leachate, and the results showed that The COD removal efficiency increased from 68% to 78% when the residence time was increased from 5 min to 15 min at 300 °C. At the same time, the addition of oxidant would also promote the degradation of organic matter.…”

“…Regarding source, PAHs are classified into two groups: pyrogenic and petrogenic (Tongo, Ogbeide, & Ezemonye, 2017). Oil percolation and oil shales deterioration are fountains of natural petrogenic PAHs, while natural sources of pyrogenic PAHs are consequences of the combustion of wood and biofuels with insufficient oxygen (Ates & Argun, 2021;Balmer, Hung, Yu, Letcher, & Muir, 2019). The distinction between petrogenic and pyrogenic PAHs in size and the molecular weight is associated with their formation temperature (Han et al, 2020;Recabarren-Villalón et al, 2021).…”

Polycyclic aromatic hydrocarbons (PAHs) contain a large group of chemical compounds that have two or more aromatic rings in their structure. These materials are produced from the incomplete burning of organic materials (such as oil, coal, wood, etc.). Natural and human activities have caused these substances to widely enter the human life cycle and affect the body’s health and functioning. After entering the body, these substances accumulate in the lungs, brain, and fat tissue, therefore, due to the high-fat mass in women, this group is more vulnerable to PAH. With the increased concentration of many of these substances in the body, problems such as genetic toxicity, carcinogenesis and mutagenesis occur. In addition to a general look at these damages, specifically how the mutagenesis process and its effects on the body are examined in detail. PAHs can become more active metabolites (BP-7-trans-dihydrodiol, benzo [a] pyrene diol-epoxide) bind to DNA, and cause mutations in DNA strands by producing ROS. PAHs produce harmful metabolites by regulating the activity of xenobiotic pathway enzymes (cytochrome P450, epoxide hydrolase, and peroxidases). For all the above, it is necessary to investigate the mechanism of their effect on the body. Due to the importance of this issue, detailed and comprehensive information is not available in sufficient quantity in this case, thus, in this research, it has been mentioned in detail and at the end of their risk assessment, it has also been examined.

“…Furthermore, the various studies showed the presence of LFL organic pollutants from both biogenic and xenobiotic origins [ 256 ]. Xenobiotic organic compounds originating from household or industrial chemicals include a variety of chlorinated aliphatics, pesticides, plasticizers, and surfactants, which have been frequently detected in the LFL [ 257 ].…”

The exposome depicts the total exposures in the lifetime of an organism. Human exposome comprises exposures from environmental and humanistic sources. Biological, chemical, and physical environmental exposures pose potential health threats, especially to susceptible populations. Although still in its nascent stage, we are beginning to recognize the vast and dynamic nature of the exposome. In this review, we systematically summarize the biological and chemical environmental exposomes in three broad environmental matrices—air, soil, and water; each contains several distinct subcategories, along with a brief introduction to the physical exposome. Disease‐related environmental exposures are highlighted, and humans are also a major source of disease‐related biological exposures. We further discuss the interactions between biological, chemical, and physical exposomes. Finally, we propose a list of outstanding challenges under the exposome research framework that need to be addressed to move the field forward. Taken together, we present a detailed landscape of environmental exposome to prime researchers to join this exciting new field.
