Since the 1970s, concerns have been raised about elevated rates of mesothelioma in the vicinity of the taconite mines in the Mesabi Iron Range. However, insufficient quantitative exposure data have hampered investigations of the relationship between cumulative exposures to elongate mineral particles (EMP) in taconite dust and adverse health effects. Specifically, no research on exposure to taco...

The COVID-19 pandemic introduced considerable challenges for respiratory protection of different population groups. Disposable medical masks and NIOSH-approved N95 filtering facepiece respirators (FFRs) are typically their only defense against the virus. At same time, continuous wearing these devices, especially some FFR models cause damage to facial skin, such as skin irritation, swelling, sca...

Random orbital (rotating) hand sanders have been found to create significant amounts of wood dust. Workers exposed to wood dusts have experienced a variety of adverse health effects such as eye and skin irritation, allergy, reduced lung function, asthma, and nasal cancer. Therefore, the National Institute for Occupational Safety and Health* (NIOSH) recommends limiting wood dust exposures to pre...

Sponsored by the Fogarty International Center, the NIEHS, and NIOSH, the International Training and Research Program in Environmental and Occupational Health (ITREOH) supports training of health professionals worldwide.

The use of large diameter disc sanders creates significant amounts of wood dust. Workers exposed to wood dusts have experienced a variety of adverse health effects such as eye and skin irritation, allergy, reduced lung function, asthma, and nasal cancer. Therefore, the National Institute for Occupational Safety and Health* (NIOSH) recommends limiting wood dust exposures to prevent these health ...

Perchloroethylene (PERC) is the most commonly used drycleaning solvent. PERC can enter the body through respiratory and dermal exposure. Symptoms associated with exposure include: depression of the central nervous system; damage to the liver and kidneys; impaired memory; confusion; dizziness; headache; drowsiness; and eye, nose, and throat irritation. Repeated dermal exposure may result in derm...

background: dental clinics are known to be one of the largest users of toxic inorganic mercury. it is well documented that dentists and dental assistants who work with amalgam are chronically exposed to mercury vapor. this study investigates exposure to mercury vapor in a dental clinic. methods: gbc cold vapor atomic absorption spectrometry (aas), using sodium borohydride as the reducing agent,...
