After an eight-day meeting of some of the world's leading experts in the diesel engine exhaust , the WHO International Agency for Research on Cancer ( IARC ) said greater regulation is needed to reduce the amount of diesel exhaust that people breathe every day .The biggest areas of concern include diesel cars , diesel power plants but also used in industrial and developing countries .
diesel engine exhaust has been classified as a possible human carcinogen . Now , there are many new studies that make this link stronger , so that the working group , with leading experts in the world , can now conclude that there is a clear , causal role , diesel engine exhaust , particularly lung cancer in humans . And especially those new epidemiological studies that examined the occurrence of cancer in people exposed to diesel engine exhaust - for example , in their workplaces , in underground mines , but also in the company truck , bus company employees , or railroad workers , working on the train dieselized fire .
So , we are not just talking about the people walking down the street that inhaling diesel fumes from cars because , of course , has become very popular again to have a diesel car on the road .
It has become more popular in some countries . You should see the state - by - state . In some countries , such as Switzerland , the United States or Brazil , there are very few diesel passenger cars , whereas in other countries , such as Germany , they are very common . And it really is not just for people who are occupationally exposed - in which we conclude there is a clear role of diesel engine exhaust and lung cancer - also from exposure to the environment , the people walking on the busy streets and other scenarios . We also have to remember that it's not just the traffic on the road - which has been set in the last 20 years with a strict and stringent emission controls - it is also a concern from other sources such as ships and trains and they are hardly regulated at all .
there may be strong evidence in the future to connect the diesel fumes with more forms of cancer
We're talking about the risk of lung cancer is mainly , but is it fair lung cancer or what else can we expect ?
Review of the epidemiologic literature clearly indicates a causal role for diesel engine exhaust to lung cancer but in addition there are also some studies that show an association with bladder cancer . So , it is classified by IARC as evidence in terminology is limited , which means that there is a credible relationship but we can not be absolutely sure that this is really causal . In addition , other cancer sites have been studied , but there is a basic yet strong enough evidence to make any conclusions . This does not mean that it can be ruled out , the only evidence available at this time . For example lung cancer and tobacco smoking : the beginning , we only know of the association with lung cancer , but now we know of 20 tobacco-related cancer sites .
mentioned tobacco smoke and diesel are now classified in the same way as tobacco - also arsenic , mustard gas , and asbestos .
This is a classification on the question of whether exposure to cause cancer . And the next question is how much improvement we see cancer . Then we have to look into what kind of exposure it . And then it depends on what the national regulatory agencies or other international bodies , such as the World Health Organization ( WHO ) in Geneva , came up with in terms of regulations and guidelines . Now , most of these carcinogens have not been banned at all - there are only a few exceptions . Even smoking tobacco or asbestos has not been banned in many places , so that when it is really a question of the regulatory agencies to enforce more stringent emissions control and tighter controls on maintenance , and so on .
