Pollution on your street


Peckham Park

Recommended Posts

out of interest - why do you say that? Is it the lack of granularity of the information on there? It links to the Kings college data so I'd agree that it won't reflect the precise reading for a particular point on a street if there is only one monitor nearby.


On the other hand - I think it challenges the idea that because Dulwich is leafy with parks, that the air isn't polluted and shows that we need to take steps now to address the air quality locally.

I did a bit of playing around with it and it seems that everywhere locally gets a '3' which tells me the data they have based this on isn't localised enough to give meaningful results.


I tried the riding school on Dulwich Common, The Horniman and Bessemer Grange School and they all had the same rating which I wouldn't expect to be the case.


In summary, the app doesn't tell us anything at the moment, other than that locally air quality is concerning (as these readings must represent local readings, just not necessarily as localised as the app suggests. Its not surprising really as reliable monitors are hugely expensive.


I do know though that based on the work my local residents association did on our streets, that the figures quoted are broadly in line with what was recorded over a shorter period, so i'm not taking any comfort in the fact that the data in that app isn't great!

The web site is brought to you by COPI:

I'll leave it up to you to decide whether you trust their interpretation of the data and if you think their scary call to action is justified.

I did some playing around also and everyone is a 3. It is looking for a response and a wonderfully helpful form to submit your dissatisfaction.

Would be interested to know how their model works. Clearly they have taken readings at a number of different sites and then just extrapolated based on a few variables; presumably 'distance from a road' is one, perhaps also altitude or prevailing wind direction. Wondering how it works exactly.

If you are near me you will get reported to the Council

    • It doesn't work as a commercial venture.  Bit churlish to say I told you so.  I told you so.  I'll send less greetings cards.  What pees me off is international postage where you can no longer send light letters at 10 grammes, normal ones up to 20g, now all at the much more expensive 100 g  Didn't we vote to take back control and price everything according to irrational units like ounces? That's some obscure humour btw   
    • Available from Monday April 8th 2024, 2on2Walkies take pride in doggie care and only walk 2 furry friends at a time. I make sure that they get plenty of doggie interaction and socialisation in the park as well as making friends. Back home happy and tired I always check that the water bowl has fresh water and always make sure the doggie is left comfortable before I leave. I'm fully insured and have a couple of slots available for local walks to either Peckham Rye Park or Dulwich Park.  Thank you!  
    • Why would they only send them recorded delivery? I used the signed for option yesterday.
    • > however I know I will have to prove it and provide a receipt,  both I can't provide. So what leads you to say that the dustmen have done damage to it?
