Forecasting Occupational Exposures Using "Well Mixed Room" Models
FORECASTING OCCUPATIONAL EXPOSURES USING “WELL MIXED ROOM” MODELS
If we don’t have the resources to sample or if we need to quickly answer questions about probable concentrations, modeling can provide estimates of potential exposures.

PRACTICAL ISSUES IN MINIMIZING WELDING FUME EXPOSURES
The first and best strategy is to control hazards at the source. In the case of welding, source reduction is most readily achieved by substituting a lower-emission welding process for a high-emission welding process.

IDENTIFYING AND ASSESSING PCBS IN THE BUILT ENVIRONMENT
Industrial hygienists are well suited to take a leading role in the anticipation, recognition, evaluation and control of polychlorinated biphenyls (PCBs), which have been identified in high concentrations in a number of building materials.

The Synergist's mission is to provide AIHA members with news and information about he occupational and environmental health and safety fields and the industrial hygiene profession. The Synergist focuses on industry trends and news, government and regulatory activities, key issues facing the profession, appropriate technical information and news on association events and activities.
The Synergist's objective is to present information that is newsworthy and of general interest in industrial hygiene. Opinions, claims, conclusions, and positions expressed in this publication are the authors' or persons' quoted and do not necessarily reflect the opinions of the editors, AIHA, or The Synergist.
SAMPLING FOR FORMALDEHYDE WITH RADIAL PASSIVE SAMPLING DEVICES
FASTER SAMPLING RATES AND HIGH CAPACITY OFFER ADVANTAGES
Sponsored by Millipore Sigma Since 1990, radial passive sampling devices have emerged that have a 360-degree adsorbing surface. By nature of this radial symmetry, the uptake rates are two to three times higher compared to axial diffusive samplers.BY KRISTEN L. SCHULTZ
