A Fuel-Based Motor Vehicle Emission Inventory.
A fuel-based methodology for calculating motor vehicle emission inventories is presented. In the fuel-based method, emission factors are normalized to fuel consumption and expressed as grams of pollutant emitted per gallon of gasoline burned. Fleet-average emission factors are calculated from the measured on-road emissions of a large, random sample of vehicles. Gasoline use is known at the stat...
متن کاملRelationship between Composition and Toxicity of Motor Vehicle Emission Samples
In this study we investigated the statistical relationship between particle and semivolatile organic chemical constituents in gasoline and diesel vehicle exhaust samples, and toxicity as measured by inflammation and tissue damage in rat lungs and mutagenicity in bacteria. Exhaust samples were collected from "normal" and "high-emitting" gasoline and diesel light-duty vehicles. We employed a comb...
متن کاملTraumatic Pneumorrhachis in a Young Male Motor Vehicle Accident Victim

The pathogenesis and etiology of this uncommon entity vary and may present a diagnostic challenge. Air in the spinal canal can be divided into primary and secondary PR, extra- or intradural PR and etiologically classified as iatrogenic, traumatic and non-traumatic. PR is typicall...
متن کاملSuicide by gunshot while driving a motor vehicle. Two additional cases.

Only two cases of suicide by gunshot while driving an automobile have been previously, and recently, reported. The author reports two additional cases of suicide by gunshot while driving a motor vehicle. ...
متن کاملTexting while driving and other risky motor vehicle behaviors among US high school students.
OBJECTIVE To assess the prevalence of texting/e-mailing while driving (TWD) and association of TWD with other risky motor vehicle (MV) behaviors among US high school students. METHODS Data were used from the Centers for Disease Control and Prevention's 2011 national Youth Risk Behavior Survey, which assessed TWD during the 30 days before the survey among 8505 students aged ≥16 years from a na...
