Does traffic exhaust cause heart disease? Scientists' latest findings

scientists have shown that air pollution has a serious impact on people'sheartblood vesselsPeople living in big cities inhale large amounts of oil-based exhaust gas every day, and the fine particles and chemicals in car exhaust can cause heart disease
,arrhythmia and hardening of the arteriesAccording to several new studies
to propose strict emissionstandards
are necessary to improve sanitationa study found that,the gas produced by the burning of gasoline and diesel engines can stimulate the biochemical pathways that cause heart disease, the Times reported
WednesdayAnother study, meanwhile,, a chemical exhaust gas called polycyclic aromatic hydrocarbon (
PAHs) can cause arrhythmia two deeper studies have shown that standard levels of air pollution
in New York and Los Angeles increase the incidence of atherosclerosis, at the
AAAS conference in Boston The reaction is particularly pronounced in people already suffering from coronary heart disease, and it increases blood cholesterol levels John Incardona of the American Oceanic and Atmospheric Institute studied the heart of zebrafish, a laboratory model of human heart standards, to observe the link between PAHs and arrhythmia He said the new findings suggest that the effects of pollutants on humans can be compared with the effects of oil slicks on aquatic organisms PAHs are formed by the inadequacy of oil and organic matter derived from it; (compiled by Ma Junhu)
