Characteristics of Real-World Non-Exhaust Particulates from Vehicles

Diesel Exhaust Particulates Characterization for Heavy Metals

This study was set out to characterize particulate emissions from transportation diesel engine in terms of heavy metals. The exhaust particulates from Mahindra DI engine were collected and analyzed at four different engine operating conditions namely idling, 40%, 70% and full load. It was found that as the load increases from idling to full load, the heavy metal content in particulates graduall...

Composition and size distribution of metals in diesel exhaust particulates.

This study characterizes the size distribution and composition of metals in diesel exhaust particulates (DEPs) emitting from four driving conditions. We quantified 17 metals in DEPs (34-1000 nm) with a total concentration ranging from 5.4-7.0 microg/m(3). Depending on driving conditions, ultrafine (<100 nm) and accumulation-mode DEPs carried up to 41% and 75% of the quantified metals, respectiv...

Control of Exhaust Emissions from Internal Combustion Engined Vehicles

Exposure to diesel exhaust particulates induces cardiac dysfunction and remodeling.

Chronic exposure to diesel exhaust particulates (DEP) increases the risk of cardiovascular disease in urban residents, predisposing them to the development of several cardiovascular stresses, including myocardial infarctions, arrhythmias, thrombosis, and heart failure. DEP contain a high level of polycyclic aromatic hydrocarbons, which activate the aryl hydrocarbon receptor (AHR). We hypothesiz...

Characteristics of Social Networks in the Theory and the Real World

The development of information and communication technology as one of the most prominent components of the expansion of social networks has revolutionized the quantity, quality, and speed of information flow unprecedentedly. One of the important consequences of the discourse of globalization of communication is the expansion of virtual participatory politics, the politicization of ethnic, racia...
