Killer air pollution

“Air pollution is the single largest environmental health risk in Europe,” says the European Environment Agency (EEA), which estimated the toll in a report.  By far the biggest killer was PM2.5 pollution: tiny particles measuring 2.5 micrometres across or less. These caused 428,000 early deaths across the 41 European countries tracked in 2014.

The main source, releasing 57 per cent of these emissions in 2015, was domestic wood burning.  Nitrogen dioxide, mostly from vehicle exhausts, cut short an estimated 78,000 lives across those countries. Ground-level ozone was the other major killer, taking 14,400 lives prematurely.  Heart disease and stroke are the most common reasons for premature death attributable to air pollution, and are responsible for 80 per cent of cases, according to the EEA.  Air pollution also worsens respiratory diseases and cancer, and has non-lethal impacts on diabetes, Alzheimer’s disease, pregnancy and brain development in children.

The main hotspots for PM2.5 pollution were Poland and northern Italy, where dozens of cities broke the European Union’s annual mean limit of 25 micrograms of particles per cubic metre of air. “Poland and the Po valley have very bad pollution, but the worst offender was Crakow in Poland. In all, 7 to 8 per cent of Europe’s urban population were exposed to PM2.5 levels above the EU limit. But under the World Health Organization’s stricter limit of 10 micrograms per cubic metre, this rose to 82 to 85 per cent.

Emissions are, nonetheless, slowly falling.  This could be sped up by limiting vehicle numbers, burning cleaner fuels and boosting pedestrianisation. The expansion of cyclimg would also help. (New Scientist)

During the very recent very cold spell there was little wind to disperse the vehicle and other fumes.  You couldn’t avoid the polluted air in Washington DC.  Poor town planning has meant that, especially during rush hour, vehicles inch forward in long traffic jams to get in and out of the city.  Add to that, you can’t help noticing the minority of people who sit alone for ages in their parked cars , running their engines to keep warm, absorbed with texting or searching the internet.  Thanks folks!  Needless to say, they are never residents.  It got me wondering why I was a committed city dweller.

  1. Oh please remain a city dweller! America’s love affair with urban sprawl has needlessly pushed up pollution. American cities badly need London-style low emission zones and congestion charges, the revenues from which should be used to invest in public transport.
    I’m afraid West London is also very bad for pollution-, in the form of nitrous oxide, as a result of so many diesel vehicles. An aversion to diesel is one of the few things American environmental policy has got right.
