“…The HQ (Hazard Quotient), which represents the non-carcinogenic risk index, for BTEX compounds was less than 1. Studies on soil media also showed higher risks for residential land and subsoil [10,11]. BTEX, especially benzene and toluene, exhibit a migratory behavior in environmental media [12].…”

BTEX (benzene, toluene, ethylbenzene, and xylene), as characteristic pollutants in chemical plant sites, are widely present in the environment and pose a serious threat to the health and safety of nearby residents. Studying the spatial distribution characteristics and transport fluxes of BTEX in soil and air at contaminated sites and the health risks they pose to humans is of great significance for fine pollution control and environmental management. This study took a typical decommissioned steel plant as a case study. A total of 23 soil and air samples were collected from different locations to investigate the spatial distribution characteristics of BTEX in soil and air. The transport and fate of BTEX in soil and air were evaluated using the fugacity model, and finally, a human health risk assessment was conducted. The results indicate a relatively severe level of benzene pollution in both soil and air. The maximum exceedance factor of benzene in soil samples is 31.5, with the concentration exceedance depth at 1.5 m. The maximum concentration of benzene in air samples is 4.98 μg·m−3. Benzene, at 5.9% of the site, shows a low flux with negative values, while other components at various locations all exhibit a trend of transport from the soil phase to the atmospheric phase. Benzene is the pollutant that contributes the most to the transport flux from soil to air within the site. The coking area and sewage treatment area are key areas within the steel mill where BTEX accumulate easily in the soil. The non-carcinogenic risk values of the individual components of BTEX in the soil are below the acceptable risk level. However, the carcinogenic risk value of benzene in the children’s exposure scenario exceeds the carcinogenic risk level of 10−6. The carcinogenic risk range of various components of BTEX in the air is 2.63 × 10−6~3.88 × 10−5, with 28.6% of the locations exceeding the threshold of 10−6. The range of the total HI (hazard index) is 2.08 × 10−4~1.81 × 10−1, all of which is below the safety threshold of 1. The results of this study will provide scientific support for the fine pollution control and environmental management of industrial contaminated sites with BTEX as their typical pollutants.

Soil is a non-renewable resource, providing a majority of the world’s food and fiber while serving as a vital carbon reservoir. However, the health of soil faces global threats from human activities, particularly widespread contamination by industrial chemicals. Existing physical, chemical, and biological remediation approaches encounter challenges in preserving soil structure and function throughout the remediation process, as well as addressing the complexities of soil contamination on a regional scale. Viable solutions encompass monitoring and simulating soil processes, with a focus on utilizing big data to bridge micro-scale and macro-scale processes. Additionally, reducing pollutant emissions to soil is paramount due to the significant challenges associated with removing contaminants once they have entered the soil, coupled with the high economic costs of remediation. Further, it is imperative to implement advanced remediation technologies, such as monitored natural attenuation, and embrace holistic soil management approaches that involve regulatory frameworks, soil health indicators, and soil safety monitoring platforms. Safeguarding the enduring health and resilience of soils necessitates a blend of interdisciplinary research, technological innovation, and collaborative initiatives.
