“…The final threshold was determined to be 0.67, with 44,021 km 2 (43.9%) of excellent habitat areas above this value and 56,178 km 2 (56.1%) of habitat management areas below it ( Figure 4 d). To evaluate the validity of the habitat quality results, we compared them with the ECVAM [ 27 ]. We found that most of the excellent habitat areas for yellow-throated martens and leopard cats were rated as grade 1.…”

This study investigated core habitat areas for yellow-throated martens (Martes flavigula) and leopard cats (Prionailurus bengalensis), two endangered forest species sensitive to habitat fragmentation in Korea. Overlaying the InVEST-HQ and MaxEnt models, priority conservation areas were identified by analyzing gaps in currently protected areas. The InVEST-HQ model showed that habitat quality ranged from 0 to 0.86 on a scale from 0 to 1, and the majority of the most suitable areas on the Environmental Conservation Value Assessment Map, designated as grade 1, were derived correctly. The MaxEnt model analysis accurately captured the ecological characteristics of the yellow-throated marten and the leopard cat and identified probable regions of occurrence. We analyzed the most suitable yellow-throated marten and leopard cat habitats by superimposing the two results. Gap analysis determined gaps in existing protected areas and identified priority conservation areas. The core area (14.7%) was mainly distributed in forests such as the Baekdudaegan Mountains Reserve in regions such as Gyeongbuk, Gyeongnam, and Gangwon; 12.9% was outside protected areas, and only 1.8% was protected. The overlap results between protected and non-protected areas were compared with different land use types. Conservation priority areas were identified as those with more than 95% forest cover, offering an appropriate habitat for the two species. These findings can be used to identify priority conservation areas through objective habitat analysis and as a basis for protected area designation and assessment of endangered species habitat conservation, thereby contributing to biodiversity and ecosystem conservation.

“…This study used the InVEST (v3.14.0) model ( (accessed on 1 October 2023)) for analysis. In addition, the habitat quality results were compared to the Environmental Conservation Value Assessment Map (ECVAM) for validation, and the habitat excellence areas were examined based on ECVAM ratings [ 27 ].…”

“…The meanings and sources of other parameters were shown in literature [36]. The total non-carcinogenic and carcinogenic risks of various types of heavy metal pollution in dust to the human body can be calculated by Equations ( 6) and (7).…”

“…Most of the pollutants are persistent in road dust, and road dust resuspension is a source of air pollution [3,4]. Several studies mentioned that road dust particle suspension has a significant impact on human health in Kuwait [5], India [6], and Korea [7]. Road dust may cause direct and indirect adverse effects on fauna, flora, and human health on the regional scale [8].…”

In this study, to investigate the contamination characteristics and potential health implications of heavy metals in road dust of the typical county in central China, heavy metals (Cd, Co, Cr, Cu, Mn, Ni, V, Pb, Zn) in typical road dust with large traffic flow, in different functional areas of Yangxin County, were determined. The results of the geo-accumulation index (Igeo) showed that Co, Mn, Ni, and V were not polluted, while other heavy metals caused different degrees of pollution. According to principal component analysis (PCA), there were three main sources of heavy metals. The result of statistical analysis showed that heavy metal pollution in road dust mainly comes from traffic activities, industrial production activities, building pollution, and the natural environment. The carcinogenic and non-carcinogenic risks of children and adults were within the safe range, and hand–oral contact was the main exposure route of non-carcinogenic risks. The non-carcinogenic risk and carcinogenic effects of heavy metals in urban road dust were acceptable to children and adults. However, we should still pay attention to the impact of heavy metals on the ecological environment and human health.

“…The roughness of the paved road surface, the relative abundance of RDS by particle size, and the intensity of precipitation influence the transport processes and pathways of RDS particles to the surrounding environment along with stormwater runoff (Mikelonis et al, 2021;Zhao et al, 2018;2022). Many studies have found that the heavy metal concentration in RDS increases with decreasing particle size (Jeong and Ra, 2022a;Logiewa et al, 2020). Guo et al (2020) performed a toxicity test of the heavy metals in road dust using two different living organisms.…”
