Measuring Submicron-size Fractionated Particulate Matter on Aluminum Impactor Disks
Submicron-sized airborne particulate matter (PM) is not collected well on regular quartz or glass fiber filter papers. We used a micro-orifice uniform deposit impactor (MOUDI) to fractionate PM into 6 size fractions and deposit it on specially designed high-purity thin aluminum disks. The MOUDI separated PM into fractions 56–100, 100–180, 180–320, 320–560, 560–1000, and 1000–1800 nm. Since the ...

متن کاملA study on the composition of size-fractionated suspended particulate matter in shallow coastal waters of Chabahar Bay
Abstract In the present study, sampling and analysis of size-fractionated suspended particulate matter (SPM) in coastal waters of Chabahar Bay have been done for the first time. Sampling has been conducted on December 25 of 2018 from 5 stations in different locations of the Bay in order to evaluate the effects of natural and human activities on SPM mass and composition. With an overall average...
متن کاملMeasuring diesel particulate matter in underground mines using submicron elemental carbon as a surrogate
Elemental carbon (EC) is used as a surrogate for regulating the exposure to diesel particulate matter (DPM) of underground metal/non-metal miners. EC was chosen as a surrogate because EC is selective to DPM and is a major component of DPM. Using EC as a surrogate also gives one the advantages of no sampling artifacts and being able to sample at all locations in the mine. Currently, EC represent...
متن کاملComparative Toxicity of Size-Fractionated Airborne Particulate Matter Collected at Different Distances from an Urban Highway
BACKGROUND Epidemiologic studies have reported an association between proximity to highway traffic and increased cardiopulmonary illnesses. OBJECTIVES We investigated the effect of size-fractionated particulate matter (PM), obtained at different distances from a highway, on acute cardiopulmonary toxicity in mice. METHODS We collected PM for 2 weeks in July-August 2006 using a three-stage (u...
