READ: NIOSH specifies best practices for dust control in coal mining (part 3)

(4 RC) - Respirable dust can be inhaled into the gas exchange region of the lungs and has long been known to be a serious health threat to workers in many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers’ pneumoconiosis (CWP), commonly known as black lung. CWP is a lung disease that can be disabling and fatal in its most severe form, progressive massive fibrosis. In addition, miners can be exposed to high levels of respirable silica dust… (NIOSH, Aug 2021)

(4 RC) - Indoor air contains a wide variety of chemical compounds. Some of these compounds, including volatile organic compounds (VOCs), originate mainly from indoor sources such as paints, building products, furnishings, glues, varnishes, and consumer and household products. Other pollutants, such as nitrogen dioxide (NO2) and ozone (O3), are classical pollutants of outdoor air that penetrate indoor environments in different ways in additional to releases from indoor sources… (WHO, Jan 2020)

(2 RC) - A soil­ gas data screening indicates that 1,4­ dioxane is a concern for vapor intrusion in a WI building occupied by workers and children. As 1,4­dioxane is highly soluble in water, it is possible that its presence in soil­ gas samples indicates the leading edge of the groundwater plume may be approaching the building. A complete indoor air investigation of the WI is necessary to evaluate the potential for current exposures… (ASTDR)

(1 RC) - The draft proposed sampling plan provides an overview of how buildings (residential, office, and public) south of Houston Street, in Manhattan, would be sampled to determine if any remaining WTC-related contamination is present. As proposed, only dust samples would be taken from buildings made available by the owners or managers. Samples would be taken from locations where exposures are likely to occur, such as in elevated horizontal surfaces.… (ATSDR, Mar 2005)

Second, can simple measures such as running air conditioning or opening windows lower the levels of formaldehyde? Accordingly, the data were generated by conducting air sampling for formaldehyde in new, unoccupied trailers under three specific conditions.… (ATSDR, Oct 2007)
