Concentrations of ultrafine particles at a highway toll collection booth and exposure implications for toll collectors.
Research regarding the magnitude of ultrafine particle levels at highway toll stations is limited. This study measured ambient concentrations of ultrafine particles at a highway toll station from October 30 to November 1 and November 5 to November 6, 2008. A scanning mobility particle sizer was used to measure ultrafine particle concentrations at a ticket/cash tollbooth. Levels of hourly averag...
متن کاملRisk Assessment of Occupational Exposure to Cement Respirable Particles and Crystalline Silica in a Cement Factory
Introduction: Cement factory workers exposure to airborne particles containing crystalline silica in Portland cement chemical compound can caused pulmonary diseases, including silicosis and lung cancer. The aim of this study was to assess the risk of occupational exposure to respirable cement dust and crystalline silica in a cement factory in Khorasan Razavi province. Methods: In this cross-se...
متن کاملAssociation of Long-Term Near-Highway Exposure to Ultrafine Particles with Cardiovascular Diseases, Diabetes and Hypertension
Ultrafine particle (UFP) concentrations are elevated near busy roadways, however, their effects on prevalence of cardiovascular diseases, diabetes, and hypertension are not well understood. To investigate these associations, data on demographics, diseases, medication use, and time of activities were collected by in-home surveys for 704 participants in three pairs of near-highway and urban backg...
متن کاملMortality in the UK industrial silica sand industry: 1. Assessment of exposure to respirable crystalline silica.
AIMS To develop a job-exposure matrix (JEM) from personal and static respirable crystalline silica (RCS) measurements in UK industrial silica sand workers. METHODS A total of 2429 personal and 583 static RCS dust samples were collected using cyclone samplers at seven UK quarries between 1978 and 2000. These data were combined, and analysis of variance using general linear models was used to e...
متن کاملAgglomerates of ultrafine particles of elemental carbon and TiO2 induce generation of lipid mediators in alveolar macrophages.
Agglomerates of ultrafine particles (AUFPs) may cause adverse health effects because of their large surface area. To evaluate physiologic responses of immune cells, we studied whether agglomerates of 77-nm elemental carbon [(EC); specific surface area 750 m2/g] and 21 nm titanium dioxide (TiO(2) particles (specific surface area 50 m(2)/g) affect the release of lipid mediators by alveolar macrop...
