Intensive measurements were performed at roadside locations in Reno, Nevada, and Durham/Research Triangle Park, North Carolina to derive mass emission factors from on-road vehicles. Measurements included continuous particulate matter (PM) concentrations (PM2.5, and PM10), wind speed, wind direction, and vehicle number, class, and speed. A multi-lag linear regression approach was applied to calc...

The measurement of particulate matter (TSP, PM10, and PM2.5) emitted by pyrotechnic articles is described. For this purpose, for entertainment purposes category F2 (i. e. consumer fireworks according to European legislation) are examined exemplarily. aim was determine reliable emission factors (EF). Different types were used obtain a more representative database. Commonly analytical methods, li...

To investigate the levels of particulate pollution in residential built environments measurements of PM(10), PM(2.5), and PM(1) and concentrations were made between 2004 and 2008 in various residencies in a UK suburban location. Measurements were carried out in three different residential settings (Types I, II and III). In type I non-smoking living rooms, the highest 24-hour mean concentrations...

BACKGROUND Air pollution is a common alibi used by adolescents taking up smoking and by smokers uncertain about quitting. However, environmental tobacco smoke (ETS) causes fine particulate matter (PM) indoor pollution exceeding outdoor limits, while new engines and fuels have reduced particulate emissions by cars. Data comparing PM emission from ETS and a recently released diesel car are presen...

Introduction The EPA's PART5 model, similar in structure to the MOBILE5a model, calculates g/mi exhaust emissions of PM and SOx from 12 classes of motor vehicles. It also calculates g/mi emissions of road dust and particles from tire wear and brake wear1. The g/mi emission factors of PART5 can be multiplied by estimates of VMT in a particular region to produce a total inventory of mobile-source...
