BEDDINGTON LANE DUST….NOT JUST ANY DUST!.....Inflammation, Oxidative stress and Allergy (this is a bit long)
1.All waste transfer stations have a problem with dust…it was thought, until recently, that this was just “clean dirt” churned up by the lorries. Unfortunately research presented at the Cranfield University annual meeting in 2008
showed that this dust was much more highly reactive because of what was on it and would cause oxidative stress in the lungs when inhaled..... “ Thus, PM10 generated by the waste transfer facility at BX4 should be considered a potential health risk to
the neighbouring residential community.”
It criticised the assumptions of our very own SLWP plan:
ERM (2006) Sustainability Appraisal Report for the Surrey Waste Plan. Environmental Resource Management
Who said it was just ordinary dust!
2.Beddington monitoring station PM10 air went over its annual mean WHO safety limits (20) on 288 days of last year (2008)…..yes….288 ! Its annual mean PM10’s were 35…that is 15 over the WHO limit, leading to an excess respiratory mortality rate of either 9% or 32% (depending on who you want to believe).It is about 3,000 feet from the sewage farm entrance, so it is likely that the readings there will be higher, but to be fair, Beddington village itself is about as far the other way. I have no idea about the respective weight of traffic coming down, or going up Beddinton Lane, but it is certain to go up significantly were any incinerator to be built.
3.“The Sensitive Receptor and the Incinerator” new particulates could add to this already woeful story, and they have all sorts of extra stuff stuck to them. As, in the old legislation, the sensitive receptor was (still is?) classed as the 6 year old girl, surely it would make more sense to place a monitoring station nearer the school playgrounds. In fact it seems daft not to be monitoring the health of our school children a lot better as so many playgrounds are near ever busier roads.
4.Inflammation: think about a cut, or a burn, or a nettle sting, or a bee or a horse-fly sting. There’s pain (or itching), reddening, swelling and extra warmth to the touch. All of that is called the inflammatory response. Blood vessels expand, and blood flows faster, lots of little white cells squeeze between the walls of the capillaries and are ready to attack or eat up the enemy, before trying to heal things. You wouldn’t believe how many links in the chain there are and how everything “talks” to everything else. You can’t see into the tiny lung tubes and air sacs , nor is pain registered, just cough or wheeze, so skin will have to do. You can see that this is not over quickly, the lungs hold a “history” of what has happened to them. Just like you would yelp if hurt near the original wound. “Mad scientists” have gassed volunteers with Volvo engines in the basements of King’s College, and shown not only the inflammatory response, by sucking some of these cells up, but also the increased sensitivity to further insult persisting for some hours. The shoppers who had wheezing in the Oxford Street experiment showed altered lung sensitivity for up to 7 hours after. So,oxidative stress is expressed as inflammation, which can lead to scarring, which can lead to restricted lung growth.The morning rush hour Nox and Particulate peaks (which can be as high as 114 [PM10 norm 20!]) soften up the lung for the summer afternoon Ozone hit,on top of 24/7 Incinerator Effects.You couldn't make it up!
5.Allergy: some of us get hay fever a bit, or a little wheeze others get mild asthma, still other get serious asthma. American scientists believe that air pollution causes asthma as a condition, that it makes attacks happen once you have got it and that it is what lies behind the huge increase in children with it. In Britain, I don’t believe this is quite agreed.
