Air pollution from cars and trucks is known to cause heart disease, cancer and respiratory problems. A recent study has revealed that exposure to freeway pollution can also cause brain damage.
A study on mice showed that when they are exposed to pollution particles approximately the size of one-thousandth the width of a human hair, causes brain damage. Further, there were also indications of memory loss and Alzheimer's disease.
