“…The post-hoc test revealed that the concentration of V was significantly different at D2 compared to all other sites and that the concentration of Mn was significantly different at D1 compared to all other sites. V is generated from the combustion of petroleum fuel [ 26 ], while Mn is released from steel and non-ferrous metal-related facilities [ 27 ]. Hence, our results may be attributed to the fact that Asan national industrial complex, which houses many steel and petrochemical plants, and the Godae·Bugok districts are in the vicinities of D1 and D2.…”

“…In Dangjin, Cu was highest in D4; D4 is near the Seokmun national industrial complex, which houses many steel and machinery plants that could have contributed to the results [ 14 ]. Meanwhile, Mn, Cu, and As have been reported to be generated by coal combustion [ 27 ]. Particularly, As is a major metabolite of bituminous coal combustion, and As, Cu, and Fe have also been reported to be released from iron smelting furnaces [ 35 ].…”

“…Kang et al (2018) [ 36 ] and Choi et al (2023) [ 37 ] reported that Fe concentrations were consistently higher in steelmaking industrial complexes, echoing our results. The Gwangyang national industrial complex is located near Y1, and the fact that the Gwangyang national industrial complex is the largest steelmaking industrial complex in South Jeolla Province with a designated area of 96,405,000 m 2 [ 27 ] might have contributed to the high F2 proportion in Y1.…”

Particulate matter (PM) can cause illness, including respiratory diseases, and PM2.5 compositions are likely to vary according to the emission profiles of industrial complexes. This study analyzed and compared the concentrations and distributions of PM2.5 and heavy metals in two regions of Republic of Korea: Yeosu·Gwangyang, which houses a massive national industrial complex, and Dangjin, which houses power plants. Further, we conducted a health risk assessment on the residents of the areas near these industrial complexes. Measurements were taken at five different points in each setting over a two-year period from August 2020 to August 2022. We found differences in PM2.5 concentrations and heavy metal composition ratios across the sites. Specifically, PM2.5 concentrations exceeded the standard of 1 at all measurement sites, while the specific heavy metals exceeding the standard varied across the sites. Ultimately, we observed regional differences in PM2.5 composition across measurement sites across and within the two regions and variations in health risks and according health effects due to the absence of PM2.5 toxicity values, and compared the health risks of two industrial complexes with different characteristics. These findings underscore the importance of considering not only PM2.5 but also its composition in exposure and health risk assessments.

The aim of this study is to investigate the protective effects of Elaeagnus angustifolia fruit extract (EAFE) on hematology, biochemical parameters, liver enzymes and damage of different tissues of male mice exposed to graphene oxide nanoparticles (GO NPs). In this research, 48 mice were divided into six groups. Hematology parameters including red blood cells (RBC), white blood cells (WBC), hematocrit (Ht), and hemoglobin (Hb), biochemical parameters such as cholesterol, triglyceride, glucose, protein, albumin, creatinine and bilirubin, liver enzymes including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) and histological damage of liver, kidney, lung and testis of mice were investigated. The results show that GO NPs in both concentrations (30 and 60 mg/kg/bw) decrease the number of RBC compared to the control group (p < 0.05). EAFE has no effect on RBC count while EAFE in combination with both concentrations of 30 and 60 mg/kg/bw GO NPs significantly (p < 0.05) improves the RBC count of mice. Also, the results show that EAFE improves the number of WBC, Ht, Hb, and biochemical parameters of mice exposed to different concentrations of GO NPs. A series of morphological changes were observed in the RBC of rats exposed to 60 mg/kg/bw GO NPs, including Dacrocyte, Poikilocyte and Schistocyte, which EAFE can improve the morphological changes caused in RBC. A series of histological damages such as degeneration and dilatation in the central vein in liver tissue, thickening and inflammatory cell infiltration in the renal capsule, peribronchiolar inflammatory cell infiltration and congestion in peribronchiolar blood vessels in lung tissue and decrease in the height of the germinal epithelium and a decrease in the population of spermatozoid cells in spermatogenic cells were observed in the testis of mice exposed to 60 mg/kg/bw GO NPs. The results show that EAFE can improve the damage caused by GO NPs in the liver, kidney and lung tissues, while it has no effect on the damage in the mice testis tissue. Therefore, GO NPs cause damage in the blood and different tissues of mice, and the use of EAFE can be effective in improving these damages.
