“…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. − …”
