The zones coloured red show a high level of pollution for the 25th. I use http://www.airtext.info/ which give daily text reports when pollution rises to 'moderate' (most of the time) to 'high' yesterday. Doug. |

However, that site was showing all green when I posted. It shows all red today, and no index for yesterday, perhaps it is not very good, airtext shows all green today, one of them is very wrong. |

The World Health Organization (WHO) states that "no safe level for airborne benzene can be recommended as it is carcinogenic to humans and there is no known safe threshold level." It also says: "Research shows that in many traffic conditions pollution levels inside cars can be up to eighteen times higher than those in "ambient" air outside." and Drivers can be exposed to even higher levels of health-damaging pollutants than those experienced by cyclists and pedestrians. so cyclists do not need to whinge about it as they have less of it to breathe than car drivers suffer. finding a figure for benzene levels in London is hard, but one study from 1998 states that the levels are around about 1 part per billion for much of the year with odd spikes in the winter up to about 9ppb http://www.agius.com/hew/resource/aq-past.htm roughly agreed with he http://www.euro.who.int/__data/asset...5_2benzene.pdf so IIUC 5ppm is vastly higher than will ever be found on the streets. |

Yes, but since cyclists are all Considerably Richer Than Everyone Else, they must cause more than their equitable share of all the major pollution from power stations, factories, etc. Wealth = consumption. |

That's a bit like saying that passive smokers have no need to complain because they breathe less smoke than smokers. IIRC, there was a 40-year study carried out in America that followed the lives of 100,000, or more, couples - where one smoked and one didn't, comparing them with couples where neither smoked, and that it showed that the non-smokers living with smokers showed an insignificant increased risk of developing a serious smoke-related illness over non-smokers who lived with non-smokers for the same period. -- Matt B |
