Silica (SiO 2) and water; Epidemiological evidence on the carcinogenicity of silica: factors in scientific judgement by C. Soutar and others. Institute of Occupational Medicine Research Report TM/97/09; Scientific opinion on the health effects of airborne silica by A Pilkington and others. Institute of Occupational Medicine Research Report TM/95/08
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.
Children, active young adults who spend time outdoors, and the elderly are particularly vulnerable. OSHA has also raised concerns about the long-term respiratory effects of occupational exposure to airborne silica at hydraulic fracturing sites. Silicosis can be associated with systemic autoimmune processes. [23]
On a national level, the Occupational Safety and Health Administration already requires fabrication shops to use “dust controls” to limit workers’ exposure to silica dust, such as saws with ...
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.
The updated standard also shifts the focus of controlling silica exposure from the use of PPE (respirators) to the use of engineering controls (such as using water-integrated tools or vacuum systems) and administrative controls (limiting exposure time per shift). Employers are still required to provide respirators when engineering and ...
Environmental regulators and public health officials have warned survivors that fire-damaged neighborhoods are probably brimming with toxic chemicals and harmful substances, such as brain-damaging ...
The Camp Lejeune water contamination problem occurred at Marine Corps Base Camp Lejeune in Jacksonville, North Carolina, from 1953 to 1987. [1] During that time, United States Marine Corps (USMC) personnel and families at the base — as well as many international, particularly British, [2] assignees — bathed in and ingested tap water contaminated with harmful chemicals at all concentrations ...
