Researchers found that exhaust fumes are responsible for lung cancer and can cause tumors in the bladder
The exhaust from diesel engines is a cancer-causing agent, said a group of experts from the World Health Organization (WHO).
The study group concluded that the smoke exhaust is responsible for cases of lung cancer and can also cause bladder tumors.
The WHO based its findings on surveys of employees at high risk, such as miners, railroad workers and truck drivers.
But the scientists stressed that everyone should try to reduce their exposure to diesel fumes.
Definitely carcinogenic
The International Agency for Research on Cancer (IARC, in its English acronym), the WHO had already classified the smoke as 'probably' carcinogenic to humans. Now, IARC changed the classification to 'definitely' carcinogen.
It is believed that people who work in industries at risk, with great exposure to carcinogens, have about 40% chance of developing lung cancer.
The doctor Christopher Portier, who led the research, said that "the scientific evidence was overwhelming, and the conclusion of the working group was unanimous - the exhaust fumes of diesel engines causes lung cancer in humans. '
'Given the additional impact of diesel particles on health, exposure to this mixture of chemicals should be reduced worldwide, "he added.
The impact on the general population, which is exposed to these particles to a much lower level and for shorter periods, is still unknown, but the risk of developing cancer is considered less.
At the same time, efforts are underway to reduce pollution caused by diesel exhaust, with the use of fuel with less sulfur and more efficient engines.
The UK charity Cancer Research UK said that employers in sectors at risk should take appropriate measures to reduce exposure of their employees. However, Lesley Walker, director of the NGO, said that the overall number of cases of lung cancer caused by diesel smoke 'is probably a small fraction of cases caused by smoking. "
