👉 Colin fumes, also known as diesel exhaust fumes (DEFs), are a complex mixture of harmful pollutants released when diesel engines burn fuel. These fumes contain particulate matter (PM), nitrogen oxides (NOx), volatile organic compounds (VOCs), and other toxic substances like carbon monoxide (CO) and polycyclic aromatic hydrocarbons (PAHs). The term "colin fumes" is a colloquialism, but it aptly describes the unpleasant odor often associated with diesel exhaust, which can be acrid and reminiscent of burning coal or gasoline. Prolonged exposure to these fumes can lead to respiratory issues, cardiovascular problems, and other health risks, making them a significant concern for both drivers and those in close proximity to diesel vehicles.
