Estimating risk of emergency room visits for asthma from personal versus fixed site measurements of NO2.
BACKGROUND We examined the impact of data source and exposure measurement error for ambient NO2 on risk estimates derived from a case-crossover study of emergency room visits for asthma in Windsor, Canada between 2002 and 2009. METHODS Paired personal and fixed-site NO2 data were available from an independent population (47 children and 48 adults) in Windsor between 2005 and 2006. We used lin...
متن کاملA Passive Sampler for Atmospheric Particles
Preliminary investigation on the feasibility of size selective passive sampling for atmospheric particles was undertaken through laboratory simulated and outdoor sampling. The passive samplers used in the research were improved from passive sampler used for sampling atmospheric organic contaminants. Sampled particle size distribution was analyzed by MasterSizer 2000 laser particle size analyzer...
متن کاملOzone measurements in South Carolina using passive samplers.
Passive samplers with two different collection substrates were used to obtain an average ozone concentration for 1 month during the summer of 2002 for each South Carolina county. One sampler contained a filter coated with indigo carmine, whose color fades when exposed to ozone. The fading was measured by reflectance spectroscopy. The other sampler contained filters that were coated with nitrite...
متن کاملA Personal, Thermophoretic Sampler for Airborne Nanoparticles
HEPA Filter Critical Flow Orifice A personal, thermophoretic particle sampler was designed to collect airborne nanoparticles in the breathing zone of exposed workers. The thermal precipitator captures aerosol by creating a 1000 ̊C/cm temperature gradient between two aluminum plates (0.1 cm separation distance) using a resistive heater, a thermoelectric cooler, a temperature controller, and two t...
متن کاملEvaluation of a personal and microenvironmental aerosol speciation sampler (PMASS).
In this study, an all-aluminum sampler was reconfigured to a lighter weight by using plastic for structural components not contacted by aerosol. Because the sampler body was made of plastic, the aluminum size-selective cyclone inlet was redesigned into a separate, removable unit. The resulting personal and microenvironmental aerosol speciation sampler (PMASS*) is a small, compact sampler design...
