Air Quality Management Area 5 - Pollution in Greenstreet (A2)

POLLUTION DIARY

  1. The Pollutants: I record four out of the five most toxic air pollutants associated with vehicles. I don't measure Ammonia (NH3).
  2. The Flow device: this measured as 90-95% accurate when compared with professional static monitors. Most of my data comes from one point close to the Tattoo Parlour on Greenstreet/A2. The advantage of the Flow device is that it can measure "on the move". This allows me to create maps in real time in different stretches of road/lane around Greenstreet and show how pollution spreads a long way into our communities.
  3. Air Quality Indicators: These are based on EU, USA, and WHO thresholds for harmful pollutants over 1 hour, 24 hours, and a year.
  4. There are no known "safe levels" of PM2.5. This very fine form of pollution has many impacts, depending on the mix and size of particles (soot? soot binding to toxins? minerals? metals? organic compounds? ozone?)
  5. You will notice that pollution incidents can spread overnight.

Comments: I was without internet access for one week. Bliss. Nevertheless, background pollution for our area has been recorded regularly. Access restored on 10th August to give a measured HIGH pollution across 24 hours. Which is the first for some weeks. I should be surprised if the work along the Lower Road is responsible, but it could be - keep an eye open!

Flow 2: We are having trouble with a faulty Flow meter.

"Queueing Theory" Illustrated
Pollution spreads to Lynsted Village
  Exceedance:-
11.30am - 14.10pm
- PM2.5 -
Graph: Wind: NNW - NW (9kph). Rain: 4.5mm. A good example of "Queuing Theory" in action! When traffic density is low enough, vehicles pass with lower contribution to pollution. But we noticed the traffic very suddenly grinding to very slow and jammed. This led to two Very High peaks (PM2.5 in particular) followed by an exceedance period, then mixed pollution into the evening. This shows that braking & idling vehicles suddenly build harmful levels of pollution. Jogging Map: Spread of pollution toward Lynsted Village.

MODERATE     Graph: Wind: NW - W (15kph). Rain: 2.00mm (evening). Something for everyone! "Low" to "Very High" - between 17.40 to 20.06pm there was a 'block' of peaks as the A2 passed it's "Service Rate". "Service Rate" is the principle that roads of different types and complexity have the ability to serve a particular volume and type of traffic - as soon as traffic hits the maximum "Service Rate" you get queues and jams and pollution concentrations.
