Is diesel exhaust harmful to humans and the environment is a topic that has been thoroughly investigated by scientists for years. Unlike most car exhaust that is mainly invisible to the eye, diesel engines give off a black cloud when accelerating. This is a heavy concentration of soot and many other chemicals that is very harmful to the human respiratory system.
The list of chemicals known to be present is sulfur dioxide, nitrogen oxides, carbon dioxides, carbon monoxide, arsenic, benzene, and many other cancer causing chemicals. Not only are these chemicals a problem because of their properties, but also because soot is in the diesel exhaust. This has harmful chemicals present which are large enough to be seen by the human eye. This soot is considered particle matter that is large enough to clog air intakes for engines and create problems for the respiratory system on its own.
If a person only has a short time exposure to diesel fumes the effects on them is only temporary. These effects include headaches, nausea, and the feeling of being lightheaded. The victim’s eyes can also water and the nose begins to run. If the soot is inhaled, then a scratchy throat, coughing, wheezing, the production of phlegm, and difficulty in breathing will occur.
Long term exposure to diesel fumes can have a devastating consequence on a person’s overall health and life. This long-term exposure has been shown to cause respiratory problems that include a reduction in lung capacity to those who had been exposed for a long time. This has led to asthma, emphysema, heart disease, lung cancer, and skin cancer in many cases.
The scientific proof has been reported for years to answer the question “Is Diesel Exhaust Harmful?” The answer is a resounding YES.
