    Exposure to dust is a known occupational hazard in the swine industry, although efforts to measure exposures are labor intensive and costly. In this study, we evaluated a Dylos DC1100 as a low-cost (~$200) alternative to assess respirable dust concentrations in a swine building in winter. Dust concentrations were measured with collocated monitors (Dylos DC1100; an aerosol photometer, the pDR-1200; and a respirable sampler analyzed gravimetrically) placed in two locations within a swine farrowing building in winter for 18-24-h periods.

    Objective: Surgical smoke generated during electrocautery contains toxins which may cause adverse health effects to operating room (OR) personnel. The objective of this study was to investigate the performance of surgical masks (SMs), which are routinely used in ORs, more efficient N95 surgical mask respirator (SMRs) and N100 filtering facepiece respirator (FFRs), against surgical smoke.

    Methods: Ten subjects were recruited to perform surgical dissections on animal tissue in a simulated OR chamber, using a standard electrocautery device, generating surgical smoke. Read More

    Comparison of Multiple Measures of Noise Exposure in Paper Mills.
    Ann Occup Hyg 2016 Jun 17;60(5):581-96. Epub 2016 Feb 17.
    2.Sahlgrenska Academy, Occupational and Environmental Medicine, Gothenburg University, Gothenburg, Sweden.
    Background: Noise exposures are associated with a host of adverse health effects, yet these exposures remain inadequately characterized in many industrial operations, including paper mills. We assessed noise at four paper mills using three measures: (i) personal noise dosimetry, (ii) area noise measurements, and (iii) questionnaire items addressing several different aspects of perceived noise exposure.

    Methods: We assessed exposures to noise characterized using the three measures and compared the relationships between them. Read More

    The Australian Work Exposures Study: Prevalence of Occupational Exposure to Respirable Crystalline Silica.
    Ann Occup Hyg 2016 Jun 17;60(5):631-7. Epub 2016 Feb 17.
    1.School of Public Health, Curtin University, Kent Street, Bentley, Western Australia, Australia;
    Background: Respirable crystalline silica (RCS) is a biologically active dust that can accumulate in the lung and induce silicosis and lung cancer. Despite occupational exposure being the predominant source, no study has described current occupational RCS exposure on a national scale in Australia. The aim of this study is to estimate the characteristics of those exposed and the circumstances of RCS exposure in Australian workplaces. Read More

    Characterizing Dust from Cutting Corian®, a Solid-Surface Composite Material, in a Laboratory Testing System.
    Ann Occup Hyg 2016 Jun 12;60(5):638-42. Epub 2016 Feb 12.
    Division of Applied Research and Technology, Engineering and Physical Hazards Branch, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, 1090 Tusculum Ave, MS: R5, Cincinnati, OH 45226, USA.
    We conducted a laboratory test to characterize dust from cutting Corian(®), a solid-surface composite material, with a circular saw. Air samples were collected using filters and direct-reading instruments in an automatic laboratory testing system. The average mass concentrations of the total and respirable dusts from the filter samples were 4. Read More
