A novel sampling cassette for field-based analysis of respirable crystalline silica J. Occup. Environ. Hyg. (IF 1.653) Pub Date : 2021-01-21 Lauren G. Chubb; Emanuele G. Cauda
Abstract Field-based methods for the analysis of respirable crystalline silica are now possible with the availability of portable instrumentation. Such methods also require the use of cassettes that facilitate direct-on-filter analysis of field samples. Conventional sampling cassettes can be modified such that they are amenable to direct-on-filter analysis while remaining compatible with common respirable

Factors influencing the filtration performance of homemade face masks J. Occup. Environ. Hyg. (IF 1.653) Pub Date : 2021-01-21 Weixing Hao; Guang Xu; Yang Wang
Abstract The outbreak of the COVID-19 pandemic is causing a shortage of personal protective equipment (PPE) across the world. As a public health response to control the pandemic, wearing homemade face coverings has been proven as a resort to protect both the wearer and others from droplets and aerosols transmission. Although aerosols and droplets can be removed through these non-medical materials with

Glove performance in a warming climate: The role of glove material and climate on permeation resistance to organophosphate insecticides J. Occup. Environ. Hyg. (IF 1.653) Pub Date : 2020-11-25 Yonatal Mesfin Tefera; Sharyn Gaskin; Leigh Thredgold; Dino Pisaniello
Abstract Hands and forearms are the principal sites of dermal exposure to organophosphate insecticides, which makes glove use one of the most important components of an exposure control strategy. However, the selection of suitable gloves depends on issues such as task, type, and concentration of organophosphate as well as cost. In addition, chemical protection performance of gloves may be temperature

The Environmental Relative Moldiness Index reveals changes in mold contamination in United States homes over time J. Occup. Environ. Hyg. (IF 1.653) Pub Date : 2020-12-14 Stephen Vesper; Larry Wymer; David Cox; Gary Dewalt; Eugene Pinzer; Warren Friedman; Peter J. Ashley
Abstract The Environmental Relative Moldiness Index (ERMI) is a scale created to compare mold contamination levels in U.S. homes. The ERMI was developed as a result of the Department of Housing and Urban Development’s (HUD) first American Healthy Homes Survey (AHHS I), which sampled 1,096 homes selected to be representative of the U.S. housing stock. In AHHS I, a dust sample from each home was analyzed

The impact of extreme reuse and extended wear conditions on protection provided by a surgical-style N95 filtering facepiece respirator J. Occup. Environ. Hyg. (IF 1.653) Pub Date : 2020-11-09 Scott Duncan; Paul Bodurtha; Cara Bourgeois; Eva Dickson; Cheryl Jensen; Syed Naqvi
Abstract Most respirators employed in health care settings, and often in first responder and industrial settings, are intended for single-use: the user dons the respirator, performs a work activity, and then doffs and discards the respirator. However, in the current COVID-19 pandemic, in the presence of persistent shortages of personal protective equipment, extended use and reuse of filtering facepiece

On-site comparison of the OSHA 47, Asset EZ4-NCO, Iso-Chek, DAN, and CIP10 methods for measuring methylene diphenyl diisocyanate (MDI) at an oriented-strand board (OSB) factory J. Occup. Environ. Hyg. (IF 1.653) Pub Date : 2020-11-16 Simon Aubin; El Mekki Hamdi; Audrey Joly; Philippe Sarazin; Jacques Lesage; Livain Breau; Mark Spence; Sébastien Gagné
Abstract Diisocyanates are occupational contaminants and known sensitizers causing irritation (skin and respiratory tract) as well as occupational asthma. Because of their physicochemical properties (semi-volatile and high reactivity) and low occupational limits, diisocyanate exposure evaluation is still a challenge nowadays for industrial hygienists and laboratories.
