Is nonoccupational noise exposure negligible?

Human occupational and nonoccupational exposure to fibers.

Human exposure to fibers in occupational and nonoccupational environments has been a health concern for nearly a century. In this review, selected results from the literature are presented to highlight the availability, limitations, and interpretive difficulties associated with the past and current human fiber exposure data sets. In the traditionally defined asbestos fibers, large amounts of th...

Is the smokers exposure to environmental tobacco smoke negligible?

BACKGROUND Very few studies have evaluated the adverse effect of passive smoking exposure among active smokers, probably due to the unproven assumption that the dose of toxic compounds that a smoker inhales by passive smoke is negligible compared to the dose inhaled by active smoke. METHODS In a controlled situation of indoor active smoking, we compared daily benzo(a)pyrene (BaP) dose, estima...

Nonoccupational environmental exposure to manganese is linked to deficits in peripheral and central olfactory function.

Manganese is of growing concern as a toxic air pollutant. It is readily transported from the olfactory epithelium to the olfactory bulb, and unlike other metals, it is transported transynaptically to structures deep within the brain. However, little is known regarding the possible effect of nonoccupational exposure to manganese on olfactory function. Using the Sniffin' Sticks test battery, we c...
