A study just published in an American Heart Association journal links atherosclerosis -- hardening of the arteries -- to car exhaust. The diesel exhaust fumes robbed what is generally known as ...
Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
Idling automobiles with the exhaust pipe blocked by snow has led to the poisoning of car occupants. [83] Any perforation between the exhaust manifold and shroud can result in exhaust gases reaching the cabin. Generators and propulsion engines on boats, notably houseboats, have resulted in fatal carbon monoxide exposures. [84] [85]
Although one study found no significant evidence that short-term exposure to diesel exhaust results in adverse extrapulmonary effects, effects that are correlated with an increase in cardiovascular disease, [64] a 2011 study in The Lancet concluded that traffic exposure is the single most serious preventable trigger of heart attack in the ...
