Car Exhaust Linked to Thickening Arteries

An international team of researchers based at the University of California at Berkeley have linked exposure to car exhaust with thickening arteries, adding a new item to the list of health problems caused by car pollution.

The study involved almost 1,500 people near Los Angeles, which has a reputation for some of the worst smog and air quality in the country. The researchers measured the thickness of the carotid artery by ultrasound and saw that for people that live within 328 feet (100 meters) of a freeway, their arteries thickened more than twice as fast as the other participants in the study.

Thickening of arteries is linked to increased risk of high blood pressure, heart attack, and stroke.

"For the first time, we have shown that air pollution contributes to the early formation of heart disease, known as atherosclerosis, which is connected to nearly half the deaths in Western societies and to a growing proportion of deaths in the rapidly industrializing nations of Asia and Latin America," said Michael Jerrett, a co-author of the study, in a statement.

The researchers say more research is needed to see how exposure to car exhaust affects sub-groups of people, such as those with high cholesterol or with low incomes. More studies are underway at the University of Southern California and in Basel, Switzerland and Girona, Spain.

What Others Had to Say

The time has come to make strict, pungent changes in the way we live our everyday life. There is no time to decrease greenhouse emissions by 2015 or 2020. We are too lackadaisical about this. Too much talk, to little action. We shun cigarettes and yet we are all "smoking" everyday. Let us stand up now and take action.

I agree with you pal. I sometimes worry why people spend too much time in discussion rather than getting into action. Only when individuals start initiatives, the rest would follow.

Car exhaust is also deemed as the main culprit for causing cancer. More and more people living in big cities are experiencing the occurance of cancer at an earlier age, even if they are non smokers. Unless our government, and ourselves, the consumers, do something about car emission (boycott petroleum cars perhaps?), we will continue to see more health problems arising from air pollution.
