Impact of mining on human health in and around mines
In this study, the age group found to receive the highest dose—and to be at highest risk for adverse health effects—was children at the age of 1 year. Furthermore, the inhalation dose and health risks are 1.4 times higher for actual mine workers when they are in the mine areas than for persons in non-mining, areas.

Gypsum Board: Are Our Walls Leaching Toxins?
Gypsum becomes poisonous gas in the landfill. However, when drywall reaches landfills--and it does so in vast quantities, as it constitutes about 15% of all construction and demolition debris--it can leach these toxic chemicals into groundwater. And in the anaerobic conditions of landfills, bacteria convert gypsum into hydrogen sulfide, a ...

Positive and negative impacts of flue gas desulfurization (FGD) gypsum
1. Introduction. Flue gas desulfurization (FGD) gypsum is a synthetic form of gypsum created as a by-product of carbon-based energy sources (typically coal combustion) (Chen and Dick, 2011; Chen et al., 2014).Limestone forced oxidation scrubbers remove sulfur dioxide from the flue gas stream of sulfur-heavy energy sources, which …
