geared   319 #121 Posted August 24, 2018 Yes me three, but it's a direct quote from the beeb all the same.  Thing is these numbers vary wildly depending on which source they come from and what their adenda really is. Begs the question; has it got so ridiculous that you can't trust anyone now??? Share this post Link to post Share on other sites Share this content via...
cgksheff   44 #122 Posted August 24, 2018 Yes me three, but it's a direct quote from the beeb all the same. Thing is these numbers vary wildly depending on which source they come from and what their adenda really is. Begs the question; has it got so ridiculous that you can't trust anyone now???  Nearly all industrial emissions are strictly controlled and scrubbed of any particle emissions. Particle emissions from vehicles are mostly due to inefficient diesel engines which are now being slowly eradicated. The figure is not unreasonable and is comparable to similar studies that can be found online.  What is also of interest is the data that shows before (of a similar order) and after figures from towns that have gone through stove controls (in the US and Canada).

flantastico   10 #124 Posted August 24, 2018 (edited) If you're interested you can read the air quality statistics for Sheffield here:-  https://www.sheffield.gov.uk/content/dam/sheffield/docs/pollution-and-nuisance/air-pollution/air-aware-campaign/Clean%20Air%20Strategy%20December%202017.pdf  The pie charts on page seven show that 15% of pollution in Sheffield derives from domestic and commercial sources combined.  Commercial includes shops, offices, restaurants, pubs etc, everything from your local takeaway to Meadowhall. Thats a big chunk of the 15%. Now consider that most houses in Sheffield burn a fossil fuel (gas) on a daily basis to provide hot water, heating and cooking. Thats another big chunk of the 15%. There are other minor sources of domestic pollution such as barbecues and garden fires.  Subtract all these from the 15% and suddenly the contribution of people lighting the stove on occasional winter evenings looks pretty negligible.  The pie charts, incidentally, show that Road Traffic accounts for about half of Sheffield's pollution.

flantastico   10 #126 Posted August 24, 2018 (edited) So who is correct then, seems like the two sources are at odds.  You only have to apply a little common sense. For much of the year, especially with a summer like this one, nobody lights a log burner or a coal fire at all. During the winter people light them on occasional evenings to provide a cheery glow in one room of the house.  Over the course of a year, is it really credible that this contributes more pollution than road traffic?  On this issue some people have an agenda and as a result you can expect to hear 'alternative truths'.

geared   319 #127 Posted August 24, 2018 (edited) of course it sounds like nonsense, but like I said it's on the BBC, in fact I'll directly quote the Government site it comes from.   The burning of wood and coal in the home is the largest single contributor to particulate matter pollution - identified by the World Health Organization as the most damaging air pollutant. Particulate matter is formed of tiny particles that can get into the body, lodging in major organs, causing short- and long-term health problems. Domestic burning contributes 38% of particulate matter pollution, compared with 16% from industrial combustion and only 12% from road transport.  Like I said previously, it seems like you get a different figure from every single source on the subject?
