“…Toxicity assessment estimates the relationship between population exposure to pollutants and the likelihood of negative effects (Bandara and Pathiratne, 2023;Ghosh et al, 2023;Wang et al, 2023). Among the six heavy metals studied in this article, Cu, Pb, Cd, and Ni all have non-carcinogenic health risks, and Pb, Cd, and Ni also have carcinogenic risks (Sharma et al, 2022;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.

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.

“…The environmental risk assessment standards for adults and children are quite different when conducting Exposure 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 [19][20][21][22][23][24][25][26], the values of each Exposure assessment parameter in this assessment are shown in…”

“…The minimum reference risk index for carcinogenicity of Cd is 9.29×10 -11 , occurring in children through respiratory exposure pathways, within an acceptable range of carcinogenic risk. Overall, the total cancer risk index of As through three pathways is relatively high, and children are higher than adults, which should be highly valued and strengthened for prevention and control; The excessive levels of As may be related to the application of pesticides in farmland or to nearby agricultural companies [20]. Zn does not have a carcinogenic risk.…”

A total of 30 samples from the downwind direction of a certain electroplating company in Jiaxing were collected in layers to analyze their heavy metal content. The soil risk assessment was conducted from the perspective of ecological and human health risks using the ground accumulation index method and human health risk assessment method. The results showed that in all samples, cadmium and arsenic far exceeded the soil background values, with an average exceeding multiple of 14.31 and 64.42, respectively, and a exceeding rate of 100%. After evaluation by the ground accumulation index, among these six heavy metals, arsenic and cadmium belong to extremely serious pollution levels. The human health risk assessment of electroplating plants found that in the exposure risk assessment, the consumption value was much greater than the harm caused by breathing and skin, and the maximum exposure damage value of arsenic to children and adults was 4.17×10− 3, among the carcinogenic risks, the risk brought by consumption is much greater than the respiratory and skin carcinogenic risk index, with the highest value score of 3.37 for cadmium, arsenic, and zinc carcinogenic risks 3.37×10− 6 、 2.42×10− 3 、1.10 ×10− 4。
