Evaluation of Productivity, Consumption, and Uncontrolled Total Particulate Matter Emission Factors of Recyclable Abrasives
… used per unit area cleaned) and uncontrolled total particulate matter (TPM) emission factors (in terms of mass of pollutant emitted per unit area cleaned and mass of pollutant emitted per unit mass of abrasive consumed). Though there have been various attempts in the past to evaluate the …

Effect of driving cycles on the particulate mass and number emissions from in-use heavy heavy-duty diesel vehicles
… distributions. Regulated gaseous emissions and total particulate matter from the exhaust were sampled from a full-flow CVS dilution tunnel system. A mini-dilution system was dedicated specifically for particle sizing, which samples partially from the raw exhaust. All vehicles were subjected to …

A Wall of Smoke: Understanding the Drivers of the June 2023 Canadian Wildfire Smoke Event for New York City
… in the New York City region, we explore how the total particulate matter output from the Quebec fires influenced PM2.5 concentrations downstream in New York City. Using injection height data from the Regional Advanced Baseline Imager + VIIRS Emissions dataset, we relate the tropospheric injection …

Vertical Concentration Gradient of Influenza Viruses Resuspended from Floor Dust
… dust constitutes up to sixty percent of the total particulate matter in indoor air. This fraction may also include virus-laden particles that settle on the floor after being emitted by an infected individual. This research focuses on predicting the concentration of influenza A viruses in …

Catching a glimpse: the visualization of Mycobacterium tuberculosis from TB patient bioaerosols
… aimed to compare the aerosolization of Mtb and total particulate matter from patients with TB during three respiratory manoeuvres: tidal breathing (TiBr), forced vital capacity (FVC), and cough. Although total particle counts were 4.8-fold greater in cough samples than either TiBr or FVC, all …

Investigation of Emission Characteristics during Low Temperature Combustion using Multivariate Adaptive Regression Splines
… engine-out emissions (oxides of nitrogen (NOx), total particulate matter (TPM), carbon monoxide (CO), hydrocarbons (HC)) and brake thermal efficiency (BTE).;The purpose of this work is to develop a statistical analysis tool to assist the emission analyst in modeling problems in which a response …

Primary and secondary emissions from upland fires in Ireland
… dioxide SO2 and nitric oxides NOx as NO), particulates and particulate fractions (fine particulate matter PM2.5, total particulate matter TPM, black carbon BC, organic carbon OC, elemental carbon EC and total carbon TC) and molecular biomarkers (levoglucosan, mannosan, galactosan, …

Dynamics of internal nutrient loading in a eutrophic, polymictic lake (Lake Rotorua, New Zealand)
… Seasonal variations in sedimentation rates of total particulate matter (TPM), total phosphorus (TP), total nitrogen (TN) and chi-a were measured at three sites in the lake using cylindrical sediment traps. Deployment of traps at different depths at each site showed an increase in sedimentation …
