Assessing Soil Pollution Potential through Spatial Heavy Metal Bioaccessibility for Health Risk Evaluation.
Incorporating bioaccessibility into health risk assessments enhances the accuracy of exposure estimates for heavy metal (HM) pollution, supports targeted remediation, and informs public health and policy decisions, particularly for vulnerable populations. Because HM bioaccessibility depends on local soil and geographic characteristics, identifying its relationship with soil properties is crucial for assessing soil pollution potential. Although HM concentrations can be measured relatively easily, bioaccessibility requires complex laboratory procedures, limiting routine applications in regulatory contexts. Integrating spatial information with bioaccessibility-based risk assessments can help identify pollution hotspots and better protect at-risk groups. This study developed a novel approach that spatially integrates HM bioaccessibility into health risk assessment. Using the simple bioaccessibility extraction test (SBET), farmland soils from 98 sites across Taiwan were analyzed to establish predictive equations for six common HMs: cadmium (Cd), lead (Pb), chromium (Cr), nickel (Ni), copper (Cu), and zinc (Zn). These equations were combined with previous soil survey data to generate spatial SBET maps across all agricultural regions in Taiwan. Results showed clear geographic variations: high Cd SBET (50%-100%) occurred in northern Taiwan with acidic soils, while elevated Cu and Zn SBET (45%-60%) were found in southern Taiwan with lower clay contents. We further applied the spatial SBET maps to Changhua County, a representative agricultural region. Infants and children exhibited higher non-carcinogenic risks (hazard index >0.01), especially in western villages, while adults had lower risks (<0.005). Seniors showed concerns of carcinogenic risks (total cancer risk index >1.0E-6). This study presents a practical and scalable framework for integrating soil bioaccessibility into spatial risk assessments, helping policymakers identify high-risk areas, prioritize remediation, and optimize healthare resource allocation, supporting Sustainable Development Goals (SDGs) of good health and well-being (SDG 3) and life on land (SDG 15).
期刊介绍:
Integrated Environmental Assessment and Management (IEAM) publishes the science underpinning environmental decision making and problem solving. Papers submitted to IEAM must link science and technical innovations to vexing regional or global environmental issues in one or more of the following core areas:
Science-informed regulation, policy, and decision making
Health and ecological risk and impact assessment
Restoration and management of damaged ecosystems
Sustaining ecosystems
Managing large-scale environmental change
Papers published in these broad fields of study are connected by an array of interdisciplinary engineering, management, and scientific themes, which collectively reflect the interconnectedness of the scientific, social, and environmental challenges facing our modern global society:
Methods for environmental quality assessment; forecasting across a number of ecosystem uses and challenges (systems-based, cost-benefit, ecosystem services, etc.); measuring or predicting ecosystem change and adaptation
Approaches that connect policy and management tools; harmonize national and international environmental regulation; merge human well-being with ecological management; develop and sustain the function of ecosystems; conceptualize, model and apply concepts of spatial and regional sustainability
Assessment and management frameworks that incorporate conservation, life cycle, restoration, and sustainability; considerations for climate-induced adaptation, change and consequences, and vulnerability
Environmental management applications using risk-based approaches; considerations for protecting and fostering biodiversity, as well as enhancement or protection of ecosystem services and resiliency.
