Impact of Lead-Contaminated Soil on Public Health

 · Lead-mining sites. The results of studies at lead-mining sites have indicated that soil lead contamination from mine tailings may be less effective in increasing PbB levels than is lead contamination derived from urban lead pollution (paint, gasoline) or atmospheric lead fallout from lead smelting operations (Steele et al. 1990).

The Potential Negative Effects Of Mining On The ...

 · Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds. Mining produces potentially hazardous/toxic tailing waste, and can leach toxic chemicals, heavy metals and air pollutants. This can lead to air pollution via air contaminants, release of greenhouse gases like methane and CO2 ...
