Another Reason Why Trucks are Dangerous
We know that the tiny particles in air pollution can clog our arteries, leading to heart attacks, but now researchers have found a connection between diesel emissions and cancer. We need to start running our trucks on biofuel!
Diesel exhaust exposure levels in the study were designed to mimic the exposure people might experience while living in urban areas and commuting in heavy traffic. The connection lies in the ability of diesel exhaust to induce the growth of new blood vessels that serve as a food supply for solid tumors. These blood vessels sprouted in mice exposed to diesel exhaust than did in mice exposed to clean, filtered air. Some of the mice were sick, but others were healthy, suggesting that cancer may perhaps be CAUSED by diesel exhaust.
