You might know your body well enough to be able to tell that it is not particularly toxic to you personally, but please consider the possibility others are more vulnerable it (because for example their bodies have more chronic inflammation than yours does).
The URL below goes to an article not about diesel exhaust or pollution, but about chronic inflammation, entitled "Understanding inflammation". Here is all the advice near the end of the article on how a reader might reduce inflammation. Emphasis mine.
>“Losing weight can have profound effects on lowering inflammation,” says Brown, who adds that eating a diet rich in fruits and vegetables and low in fats, processed foods, and sugars is generally a good idea, though more study needs to be done to determine how it might affect inflammation. Exercising, which causes an acute inflammatory response in the short term, but an anti-inflammatory one when we regularly get moving, is another strong step to take, he adds. Other researchers advise getting plenty of sleep, lowering stress levels, and seeking out treatment for inflammation-inducing culprits, such as gum disease and high cholesterol levels. Avoid contact with heavy metals such as mercury, which is found in dangerous amounts in some large fish, and limit exposure to substances, such as diesel exhaust and cigarette smoke, that can set off the immune system.
