True, Diesel exhaust contains soot, arsenic, benzene, formaldehyde and nickel which are all carcinogen when breathed in. Globally diesel and gasoline exhaust is causing far more cases of cancer than secondhand cigarette smoke...
Also note that the damaging effects of gasoline and diesel exhaust go
way beyond causing cancer:
- Diesel and gasoline exhaust also contains nitrogen oxides which can trigger asthmatic attacks and other respiratory diseases and can trigger allergic reactions as well.
- Diesel exhaust can irritate the eyes, nose, throat and lungs, and it can cause coughs, headaches, lightheadedness and nausea.
- Fine particle exhaust also endangers people with various forms of heart disease and the elderly in general.
- Children are exponentially more exposed: not only are they smaller and thus more vulnerable (the body mass to lung surface ratio is lower), but they also breathe and live at much lower heights, which has even higher concentrations of exhaust.
- Pets are the most exposed: they are often the smallest and breath right at the exhaust pipe level.
- The 'carbon dioxide dome' around inner cities is decreasing cognitive performance of everyone exposed to that air.
- There's significant property damage as well:
- diesel and gasoline exhaust contain aggressive chemicals that degrade real-estate, adding billions of dollars of building maintenance cost per year,
- diesel and gasoline exhaust pollutes and damages animals and plants and other agricultural products.
- Not to mention the slow moving wrecking ball of global warming, with hundreds of billions of current damages and costs, and trillions of future damages and costs.
I know I'm preaching to the choir here, but diesel and gasoline exhaust are not just carcinogens, they are literal
'poison gases' with a
huge range of negative externalities which costs and damages are not billed to Exxon Mobile or Koch Industries ...
