“The idea you can build a school at 300 meters from a freeway, one has to re-look at this issue,” said John Froines, Professor at UCLA’s Department of Environmental Health Sciences.

As part of the study to determine the effect of ultra fine particles from tailpipe emission, Froines along other research entities studied the physiological effects of these particles on communities in California.

California’s weather and climatological conditions are ideal for such study, he said. The California Air Resources Board found that international trade and the movement of goods affected the areas environment, he added.

Described as a problem not anticipated since its begging half a decade ago, the vapor emissions from transportation devices condense, turning into particles. “Vapor emissions it’s not just what comes out of the pipes,” he said.

Particles were found to have traveled up to 2,500 meters from the highways into adjacent neighborhoods.

Cell response to these particles showed to escalate from defense building mechanisms to inflammation.

Particles are the size of viruses and have “irreversible” and “accumulative” effects, especially in the mitochondria of the human cells.

Froines added that driving in the area one would inhale “a million and a half particles in a single breath you take.”
