Comparative 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...
متن کاملMeasuring 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 کاملAirborne Particulate Matter Density in Traditional Bakeries of Saveh, Central of Iran, in 2020
Introduction: High concentration of inhalable airborne particles can increase the risk of lung disease in exposed people. This study aimed to determine the respirable particulate matter (PM5) concentration in traditional bakeries of Saveh in 2020. Materials and Methods: This cross-sectional descriptive study was conducted among 25 bakeries where the samples were collected by cyclone and teflon...
متن کاملMutagenicity of airborne particulate matter PM10.
Mutagenic activity of extractable organic matter (EOM), from airborne particles collected over winters in four towns of Czech Republic, was investigated by the means of Salmonella typhimurium indicator strains TA98 and YG1041 using the Ames plate incorporation assay. Mutagenicity of all tested samples showed significant dose-related increase in number of revertants per mg of EOM. The direct mut...
