Sydney's Degrading Air Quality

Discussion in 'General Motorcycling Discussion' started by bradc1988, Feb 14, 2013.

  1. So I did a quick search on this and nothing came up.

    Has anyone noticed the declining quality of air when out riding? I've only been riding for close to 4 years now but over the past year or so there has been a noticable increase in crap in the air.

    I might be a little more sensistive because I have mild hay fever, but the short 15km trip to work will sometimes see me turn up with a build up of black gunk in the corner of my eyes. I can actually feel the particulates hit my eyes.

    Anyone else notice this? Is it due to poorer petrol quality? More cars? Lack of rain to clear dust?

    I think I might have to invest in some goggles as it's summer and I much prefer visor up!
  2. Try riding through the tunnels in melbourne!!
  3. Black particles are generally bits of rubber from tires. I think I remember hearing the average tire loses about 3kg in its life span. Bit of back of the envelope maths, say a car tire is replaced on average every 2 years, 4 per car, 2 million cars in Sydney = 12 000 tonnes of rubber going somewhere in Sydney each year = 185 tonnes of rubber a day, mostly turning into particles.
