“Our research found that the particulate matter from diesel exhaust stimulated a ‘death pathway’ response that the body uses to dispose of damaged cells. This response caused the airway cells to fuse together and die.
“We saw hardly any cell death after treatment with biodiesel particulates.”
Associate Professor Ackland said that the results of the study provide support for calls to move towards replacing petrol and diesel with cleaner biofuels.
“It is clear that breathing in diesel fumes is going to have a far more detrimental effect on our health than biodiesel. Given the level of cell death we have found, diesel exhaust could be the cause of respiratory disorders such as asthma and could even be implicated in cancer,” she said
