Diesel Pollution and Atherosclerosis
A recent study done by UCLA has found a correlation between diesel exhaust pollution and atherosclerosis. Atherosclerosis, which is the hardening of the arteries, is a dangerous condition that induces a greater susceptibility to heart attacks and strokes. The study shows that when polluted air particulates intermingle with cholesterol fats, they can trigger genes that cause blood vessel inflammation which can further lead to cardiovascular disease.
