Exposure to bioaerosol in hospitals is associated with health effects but in the field of veterinary hospitals there are limited articles on bioaerosol concentration especially in Southeast Asia. This investigation of aerosol bacteria (cross-sectional study) was conducted in two veterinary teaching hospitals located in Thailand. Airborne bacteria were collected from air samples infour room types (reception hall, intensive care unit, out-patient department and in-patient hospital department) in each hospital using a sieve impactorair sampler at different periods (8:00–10:00, 10:00–12.00 and 13:00–15:00). The results revealed high bacterial contamination in all collected air samples. The average levels of total viable bacteria count …

Hexavalent chromium is a corrosion inhibitor found in the primer of most aircraft platforms across the Department of Defense (DoD), from fighter jets to transports. It is also known to cause cancer in humans. Currently, the Occupational Safety and Health Administration (OSHA) legal exposure limit is 5 μg/m3 for workers exposed to hexavalent chromium. A non-regulatory scientific body has recently recommended lowering this exposure level over a factor of ten and sampling with a different sampler that collects particles with the same efficiency as the nose during inhalation. This inhalable sampler collects more particles than the one currently used …
