average wind speeds blows the pollution away more easily

I`m not so sure thats true, winds tend to react differently to different buildings and make the pollution build up in certain places, you only have to look at dirt build up in corners and places where the wind turns twister (like a vacuum cleaner ) to see where the diesel dirt is going

even on a lot of windows and walls get black dirt build up which must be caused by diesel particulate build up. also buildings around major A roads and Motorways suffer it as well

there are still a lot of vans and old diesels around that spew black smoke out!

I briefly considered a diesel during my recent car search.

However, bad publicity of the kind which accompanied the emission figures scandal can prove to be a potent influence upon the decision making processes of those who have few alternative sources of knowledge to guide them, and in the end it seemed too much of a risky endeavour.

I think it was more a case of most people ignored any warnings about diesels, any emmisions warnings were ignored because it suited the wallet most of the time, imo its all too little too late as with all things

It seems another report says household chemicals are equal to or worse than particulates inhalation due to the chemicals being inhaled in an enclosed space, so we will wait and see what happens about that. If you want proof just google household chemicals and particulates.

probably swept under the carpet untill the green brigade get their teeth into it?
