“…The environmental risk assessment standards for adults and children are quite different when conducting exposure assessments. Table 2 shows the values of each exposure assessment parameter in this assessment according to China's site environmental assessment guidelines, the USEPA health risk assessment method, and the actual research conclusions at home and abroad in recent years (Hasanzadeh et al, 2022;Aly-Eldeen et al, 2023;Hou et al, 2023;Jin et al, 2023;Pandion et al, 2023;Siddique et al, 2023;Zheng et al, 2023).…”

The auto parts industry occupies an important strategic position in our national economy, which brings about the pollution problem in the processing of auto parts, particularly in soil polluted by heavy metals. Soil samples were collected from an automobile parts company in Jiaxing, China, and the data were evaluated using the land accumulation index method. The study found that the heavy metal pollution in the downwind direction of the Automobile Parts Co., Ltd. is mainly As, CD, and Zn mixed heavy metal pollution, and the distribution is uneven. The coefficient of variation of As was the largest, and the regional variation amplitude was large. The coefficient of variation of CD, Cr, and Ni is 50%, that of Zn is 39.38%, and that of PB is the lowest. The accumulative index of AS and CD was 6, which was a very serious pollution level. The content of As was 1994.7 mg/kg, exceeding the standard by more than 44 times, and the distribution of As in soil was uneven. The pollution level of Zn is 3, which belongs to the moderate level. The pollution degree of heavy metals in the soil decreases as the distance from the downwind outlet of the plant increases. According to the health risk assessment, the main route of heavy metals entering the body is through the mouth by breathing. Among exposure routes, oral exposure to heavy metals is the most harmful, so we need to pay special attention to farmland soil heavy metal pollution.

“…Since the emergence of this concept, ER has been instrumental in the evaluation of ecological quality and management of the ecological environment, and a structural framework with international leadership has been initially developed in terms of theory [17] and methodology [18]. Early ER assessment mainly focused on the study of environmental pollution, which generally includes four parts: heavy metals [19,20], sediments [21,22], soil [23,24], and polycyclic aromatic chemicals [25,26]. Meanwhile, the scale of ER assessment is mostly a single risk source and a single risk recipient.…”

The situation of resource utilization and eco-environment protection remains critical globally. The harmony between eco-environment health and water-energy utilization efficiency is a strong support for the realization of high-quality development. In this paper, an Assessment-Decoupling two-stage framework was developed to investigate the relationship between water-energy resource utilization and ecological security. In detail, an improved input-output indicator system was constructed to assess the water-energy resource utilization efficiency (WEUE), and its influencing factors were examined from multiple system perspectives; then, we intended to evaluate the ecological risk (ER) from a raster-scale perspective based on land-use types; and finally, the decoupling idea was introduced to quantify the fitness relationship of the above two aspects. The framework was applied to Henan Province, China. The study found that: (1) the WEUE of Henan Province shows a “W” pattern of development during 2000–2020; in 2000–2010, the WEUE of South Henan declined, while in 2010–2020, the WEUE of Henan Province gradually improved, with significant increases in various districts. (2) The ecological risk index (ERI) in Henan Province generally shows a decreasing trend, and the spatial difference is more obvious, with the high-risk areas mainly concentrated in the central, east, and south Henan, and the west of Henan is mainly a low-risk area. (3) There is strong spatial variation in the decoupling states of WEUE and ERI of the 18 districts in Henan Province, and the differences become more pronounced over time. The number of districts with a strong negative decoupling state has been increasing during the entire period, and a total of 14 districts have reached the above state in 2020. The developed framework offers a new idea for clarifying the relationship between resource utilization and ecological conditions, and the obtained results can provide data support for the realization of sustainable development.

The auto parts industry occupies an important strategic position in our national economy, which brings about the pollution problem in the processing of auto parts, especially in the soil polluted by heavy metals. Soil samples were collected from an automobile parts company in Jiaxing, China, and the data were evaluated by the land accumulation index method. It is found that the heavy metal pollution in the downwind direction of the Automobile Parts Co., Ltd. is mainly As, CD, Zn mixed heavy metal pollution, the distribution is not uniform. The coefficient of variation of As was the largest, and the regional variation amplitude was larger. The coefficient of variation of CD, Cr and Ni is 50%, the coefficient of variation of Zn is 39.38%, and the coefficient of variation of PB is the lowest. The accumulative index of AS and CD was 6, which was a very serious pollution. The content of As was 1994.7 mg/kg, the multiple of over-standard was more than 44 times, and the distribution of As in soil was irregular. The pollution level of Zn is Grade 3, which belongs to moderate pollution. The farther away from the downwind outlet of the plant, the lower the pollution degree of heavy metals in the soil. According to the health risk assessment, the main route of heavy metals entering the body is through the mouth, through the way of breathing. Exposure to heavy metals is far less harmful than oral exposure, so we need to pay special attention to farmland soil heavy metal pollution.
