Development of a new methodology for multifaceted assessment, analysis, and characterization of soil contamination

Development of a Multifaceted Perspective for Systematic Analysis, Assessment, and Performance for Environmental Standards of Contaminated Sites

“…The current standard system still possessed some limitations, including the diversity in risk management for protected eco-receptors, the inflexible utilization of exposure parameters in risk assessment models, insufficient guidance on remediation technologies, and covering the shortage of comprehensive test methods of chemicals. Table outlined the proposed and potential development task of improving the enrichment of current environmental standards for contaminated sites, supplying the designed optimization and favorable suggestion for the standard system. ,, The following key areas are outlined: (a) Advancing the system of identification and risk-based standards for contaminated sites by developing technical guidelines for ecological soil contamination and expanding the assessment of various receptors (screening risk levels to protect ecology and groundwater). (b) Expanding the range of standards for emerging pollutants and nonconventional chemicals with soil contaminant testing methods and appropriate indicators .…”

“…Local standards are those adopted and publicly released in a region of the country. Group standards are standards independently formulated and released by groups in accordance with the standard-setting procedures established by the groups and voluntarily adopted by society to fill the gaps in existing standards. ,, …”

“…With the continuous demand for urban development and the demolition of buildings, a large number of contaminated sites have been created causing serious environmental problems in China, due to the waste gas, wastewater, and waste residue emitted from the activities of industrial and mining production and also high regional background level. − These sites would pose a potential risk to human health and the ecological environment through the contamination of soil, sediment, surface water, groundwater, and air migration by hazardous chemicals, − such as heavy metals (e.g., Pb, Cd, Cr, Hg), metalloid (e.g., As), volatile organic compounds (VOCs), , semivolatile organic compounds (SVOCs), and pesticides. , It resulted in different exposure routes such as soil inhalation, surface and groundwater drinking, plant uptake, and accumulation in the food chain for different harmful contaminants. , Additionally, some chemicals in the contaminated soil can leach or enter the groundwater with seepage water, resulting in deterioration of groundwater quality over time and eventually leading to pollution. − …”

Multifaceted Insight into Sensitivity Analysis and Environmental Impact on Human Health of Soil Contamination Risk Assessment

“…Soil contamination is a complex and challenging issue that involves many types of hazardous metals, volatile organic compounds (VOCs), and semivolatile organic compounds (SVOCs) at contaminated sites. − Human health risk assessment is a significant method for estimating the probability of adverse health effects on humans. − The processes consist of hazard identification, dose–response assessment, exposure assessment, and risk characterization. , Sensitivity analysis is a process that evaluates the effects of changes in key parameters on human health risks and environmental impact results. , It entails identifying key parameters and evaluating the impacts of changes in these parameters on the uncertainty of calculated ratios. This, in turn, facilitates the determination of the appropriate risk management strategies.…”
