A novel two-step sequential bioaccessibility test for potentially toxic elements in inhaled particulate matter transported into the gastrointestinal tract by mucociliary clearance
A novel two-step sequential extraction has been developed to assess the bioaccessibility of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn in airborne particulate matter following inhalation and transport into the human gastrointestinal tract by mucociliary clearance. A new artificial mucus fluid (AMF) was used to determine the bioaccessible potentially toxic element (PTE) fraction in the upper airways,...
متن کاملLow cost air quality monitors to evaluate nanosized particulate matter. A pilot study
Particulate matter is defined as a mixture of airborne solid particles and liquid droplets that can be inhaled and may cause serious health problems. Such elements are currently measured utilizing air quality monitoring devices that provide information on PM 10 and PM 2.5 levels giving information on pollution levels. However, many difficulties are encountered in the determination of nanosized ...
متن کاملCorrelating Particulate Matter Mobile Source Emissions to Ambient Air Quality
This paper describes the work and results of the second phase of research sponsored by the Federal Highway Administration (FHWA) initiated to study the relationship between traffic activity and ambient PM2.5 concentrations. The study, entitled “Estimating the Transportation Contribution to Particulate Matter Pollution”, had the objective of performing a correlation analyses on particulate matte...
متن کاملRetrieving of Inhalable Particulate Matter Based on SPOT Image
Abstract: This study built a model with DVI, which is computed by near-infrared and red bands of SPOT-5 image, and observed concentration of PM10 (inhalable particulate matter) to retrieve concentration of PM10 in SPOT-5 image of Beijing urban acquired in 2007. Spatial distribution trends of PM10 are basically identical between retrieved result and observed data. In 2007, inhalable particulate ...
متن کاملEffects of inhalable particulate matter on blood coagulation.
BACKGROUND Particulate matter (PM) exposure has been linked to increased risk of cardiovascular disease, possibly resulting from hypercoagulability and thrombosis. Lung and systemic inflammation resulting from PM inhalation may activate blood coagulation, but mechanisms for PM-related hypercoagulability are still largely unknown. OBJECTIVES To identify coagulation mechanisms activated by PM i...
