Workplace exposure to particulate matter, bio-accessible, and non-soluble metal compounds during hot work processes.

J Occup Environ Hyg 2019 Apr 15:1-9. Epub 2019 Apr 15.

a Department of Chemical and Biological Work Environment , National Institute of Occupational Health , Oslo , Norway.

While exposure to air contaminants from metal arc welding at workplaces has been intensively investigated over the last five decades, other hot work processes, such as flame and plasma cutting, air carbon arc gouging, and surface grinding have not received as much attention. Exposures to particulate matter (PM) during selected hot work processes, such as metal active gas (MAG) and manual metal arc (MMA) welding, flame and plasma cutting, air carbon arc gouging, and surface grinding were measured. Respirable, inhalable, and "total" fractions of the PM were collected with different air samplers in the workers' breathing zone. Read More

Targeted GC-MS analysis of firefighters' exhaled breath: Exploring biomarker response at the individual level.

J Occup Environ Hyg 2019 Apr 1:1-12. Epub 2019 Apr 1.

d Illinois Fire Service Institute, University of Illinois at Urbana-Champaign , Champaign , Illinois.

Biomarker measurements can provide unambiguous evidence of environmental exposures as well as the resultant biological responses. Firefighters have a high rate of occupational cancer incidence, which has been proposed to be linked in part to their increased environmental exposure to byproducts of combustion and contaminants produced during fire responses. In this article, the uptake and elimination of targeted volatile organic compounds were investigated by collecting the exhaled breath of firefighters on sorbent tubes before and after controlled structure burns and analyzing samples using automated thermal desorption-gas chromatography (ATD-GC/MS).

Kinetics of isoflurane and sevoflurane in a unidirectional displacement flow and the relevance to anesthetic gas exposure by operating room personnel.

J Occup Environ Hyg 2019 Mar 9:1-8. Epub 2019 Mar 9.

b Department of Life Science Engineering , University of Applied Sciences , Giessen , Germany.

International guidelines recommend the use of ventilation systems in operating rooms to reduce the concentration of potentially hazardous substances such as anesthetic gases. The exhaust air grilles of these systems are typically located in the lower corners of the operating room and pick up two-thirds of the air volume, whereas the final third is taken from near the ceiling, which guarantees an optimal perfusion of the operating room with a sterile filtered air supply. However, this setup is also employed because anesthetic gases have a higher molecular weight than the components of air and should pool on the floor if movement is kept to a minimum and if a ventilation system with a unidirectional displacement flow is employed.

J Occup Environ Hyg 2019 Mar 22;16(3):242-249. Epub 2019 Feb 22.

a National Institute for Occupational Safety and Health , Pittsburgh Mining Research Division , Pittsburgh , Pennsylvania.

A person-wearable dust monitor that provides nearly real-time, mass-based readings of respirable dust was developed for use in underground coal mines. This personal dust monitor (PDM) combined dust sampling instrumentation with a cap lamp (and battery) into one belt-wearable unit, with the air inlet mounted on the cap lamp. However, obsolescence of belt-carried cap lamp and batteries in coal mining ensued and led end users to request that the cap lamp and battery be removed from the PDM. Read More

Firefighter hood contamination: Efficiency of laundering to remove PAHs and FRs.

J Occup Environ Hyg 2019 Feb 7;16(2):129-140. Epub 2019 Feb 7.

f Virginia Institute of Marine Science, College of William & Mary , Williamsburg , Virginia.

Firefighters are occupationally exposed to products of combustion containing polycyclic aromatic hydrocarbons (PAHs) and flame retardants (FRs), potentially contributing to their increased risk for certain cancers. Personal protective equipment (PPE), including firefighter hoods, helps to reduce firefighters' exposure to toxic substances during fire responses by providing a layer of material on which contaminants deposit prior to reaching the firefighters skin. However, over time hoods that retain some contamination may actually contribute to firefighters' systemic dose. Read More

Collection of airborne ultrafine cellulose nanocrystals by impinger with an efficiency mimicking deposition in the human respiratory system.

J Occup Environ Hyg 2019 Feb 1;16(2):141-150. Epub 2019 Mar 1.

a Virginia Polytechnic Institute and State University - Materials Science and Engineering , Blacksburg , Virginia , United States.

As cellulose nanocrystals (CNCs) are increasing in production, establishing safe workplace practices in industry will be paramount to their continued use and growth. Particles other than CNCs with similar high aspect ratios have exhibited toxicity on inhalation. Safeguards are needed to monitor concentrations of CNCs in air in industrial and laboratory settings to protect workers. Read More

Efficacy of Paired Electrochemical Sensors for Measuring Ozone Concentrations.

J Occup Environ Hyg 2019 Feb 21;16(2):179-190. Epub 2019 Mar 21.

a Department of Environmental Health and Engineering , Johns Hopkins Bloomberg School of Public Health , Baltimore , Maryland.

Typical low-cost electrochemical sensors for ozone (O) are also highly responsive to nitrogen dioxide (NO). Consequently, a single sensor's response to O is indistinguishable from its response to NO. Recently, a method for quantifying O concentrations became commercially available (Alphasense Ltd. Read More

Occupational exposure to trichloramine and trihalomethanes: adverse health effects among personnel in habilitation and rehabilitation swimming pools.

J Occup Environ Hyg 2019 Jan 16;16(1):78-88. Epub 2019 Jan 16.

d Department of Chemical and Biological Work Environment , National Institute of Occupational Health , Oslo , Norway.

Personnel in swimming pool facilities typically experience ocular, nasal, and respiratory symptoms due to water chlorination and consequent exposure to disinfection by-products in the air. The aim of the study was to investigate exposure to trichloramine and trihalomethanes (chloroform, bromodichloromethane, dibromochloromethane, and bromoform) from the perspective of adverse health effects on the personnel at Swedish habilitation and rehabilitation swimming pools. The study included 10 habilitation and rehabilitation swimming pool facilities in nine Swedish cities. Read More

A field evaluation of a single sampler for respirable and inhalable indium and dust measurements at an indium-tin oxide manufacturing facility.

J Occup Environ Hyg 2019 Jan 28;16(1):66-77. Epub 2019 Jan 28.

a Respiratory Health Division , National Institute for Occupational Safety and Health , Morgantown , West Virginia.

Indium-tin oxide production has increased greatly in the last 20 years subsequent to increased global demand for touch screens and photovoltaics. Previous studies used measurements of indium in blood as an indicator of indium exposure and observed associations with adverse respiratory outcomes. However, correlations between measurements of blood indium and airborne respirable indium are inconsistent, in part because of the long half-life of indium in blood, but also because respirable indium measurements do not incorporate inhalable indium that can contribute to the observed biological burden.

Endotoxin, cat, and house dust mite allergens in electrostatic cloths and bedroom dust.

J Occup Environ Hyg 2019 Jan 28;16(1):89-96. Epub 2019 Jan 28.

a Wellington Asthma Research Group, Department of Medicine , University of Otago , Wellington , New Zealand.

Environmental exposure to endotoxin, Fel d I (cat) allergen and Der p I (house dust mite) allergen have been associated with asthma symptoms and have been measured in the environment using various sampling methods, including the electrostatic dust collector. The objectives of this study were to investigate whether levels of endotoxin and allergens were detectable in electrostatic dust collectors and to examine the correlation of allergen and endotoxin levels between electrostatic dust collectors and vacuum sampling methods (floor dust and mattress dust). Electrostatic cloths, bedroom floor dust and mattress dust samples from a subset of 60 homes were randomly selected from the Health of Occupants of Mouldy Homes study for allergen and endotoxin analysis.

The impact of canister geometry on chemical biological radiological and nuclear filter performance: A computational fluid dynamics analysis.

J Occup Environ Hyg 2019 Jan 16;16(1):41-53. Epub 2019 Jan 16.

b Defence Science and Technology Laboratory , Salisbury , UK.

Steady-state axisymmetric simulations using the Reynolds-Averaged Navier-Stokes equations have been carried out in order to optimize the performance of a Chemical, Biological, Radiological, and Nuclear (CBRN) canister filter for its use in a powered air-purifying respirator (PAPR). Alterations have been made to the shape of the canister, the spacing of the rear wall of the canister with regard to the carbon filter, and the bracketing between (i) the particulate filter and the carbon bed and (ii) the carbon bed and the canister wall. The pressure drops across the canister and the residence time distribution at the rear of the carbon bed have been analyzed in detail based on an extensive parametric analysis involving the aforementioned variations.
