Desert lung disease may be related to Al Eskan disease, a lung disorder thought to be caused by exposure to sand dust containing organic antigens, which was first diagnosed after the 1990 Gulf war. [57] The relative importance of the silica particles themselves and the microorganisms that they carry in these health effects remains unclear. [58]
The grinding and sanding of synthetic engineered stone exposes workers to high levels of lung-scarring silica. Experts say the health risk should have been clear long before workers began falling ill.
Various health programs have arisen to deal with the ongoing health effects of the September 11 attacks. The World Trade Center Health Program, which provides testing and treatment to 9/11 responders and survivors, consolidated many of these after the James Zadroga 9/11 Health and Compensation Act became law in January 2011.

The health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as fire and dust explosion hazards. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
