Diesel air pollution's health effects studied in Europe

Live in Los Angeles or Houston? You are probably familiar with smog, otherwise known as lingering air pollution. It can be seen, ingested and can wreak havoc inside our respiratory systems in many cases.

In Europe, a pair of real-world studies recently showed the exact effects on health based on the effects of diesel engine pollution. The results? After 11 years of slight improvements in air pollution levels in Switzerland, measurable health benefits were seen in citizens.

In another study published at the same time, those with asthma saw a greater loss of breathing by walking on a street polluted by diesel fumes compared to walking through a traffic-free park.
