POLLUTION DIARY
HISTORIC DATA - YEAR 1
-- 22nd FEBRUARY 2019 to END FEBRUARY 2020 --
Return to Current Year (March 2021-February 2022)
(the small overlap of data for February is deliberate to aid reading/switching screens)
Explore Year 2 - after which Flow 1 was replaced with Flow 2 Device
- The Pollutants: I record four out of the five most toxic air pollutants associated with vehicles. I don't measure Ammonia (NH3).
- 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 new Blind Company 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.
- Air Quality Indicators: These are based on EU, USA, and WHO thresholds for harmful pollutants over 1 hour, 24 hours, and a year.
- 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?)
- You will notice that pollution episodes can spread overnight.
AIR QUALITY INDICATOR (AQI) USED ON THIS SITE
(Bear in mind, there are no known lower safety levels for PM2.5)
NOTE: The static measurements that I have been making are taken along the A2 but West of the AQMA5.
Bear in mind that the measurements made by SBC have only relatively recently been relevant once they responded to Lynsted with Kingsdown Parish Council's criticism that SBC 'diffusion tubes' were sited unrealistically high above the heads of pedestrians.
SBC also fails to test for the more harmful PM2.5, PM10, and VOCs.
The appearance is that SBC would rather NOT know how much physical harm their decisions on planning have on our DAILY lives!

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.

"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. | ||

24th October | 16 | 19 | 3 | 17 | LOW | A good day. PM2.5 highest in morning; Afternoon a wider spread of pollutant fractions also at low levels. The figure is at the margin for "Low". | ||
25th October | 11 | 26 | 3 | 15 | MODERATE | PM10 makes up nearly all the pollution fractions | ||

28th October | 41 | 27 | 28 | 5 | MODERATE | "Very High" (173) [9.47-10.23am] when heavy machinery movement was stuck. Congestion remained for a while afterwards. | ||
29th October | 66 | 35 | 8 | 10 | HIGH | EXCEEDANCE | Incomplete data. Although it appears there was a "Very High" peak of NO2 - this cannot be confirmed - battery ran out. | |
30th October | 62 | 32 | 4 | 11 | HIGH | EXCEEDANCE | The pollution was very strongly dominated by PM2.5 throughout the day. | |
31st October | 61 | 40 | 33 | 15 | HIGH | EXCEEDANCE | EXCEEDANCE | Interestingly the "Very High" measurement was dominated by NO2, the bulk of pollution over the 24-hour period was, however mainly PM2.5 pollutants. |
NOVEMBER 2019 | ||||||||
1st November | 23 | 21 | 2 | 26 | MODERATE | The peaks to the right were made up mostly by PM10 pollutants | ||
2nd November | 22 | 22 | 2 | 25 | MODERATE | The main components of pollution were in the PM2.5 and PM10 fractions of pollutants measured. | ||
3rd November | 33 | 23 | 10 | 18 | MODERATE | The sharp peak at midday was dominated by the NO2 fraction of pollutants. | ||
4th November | 35 | 22 | 2 | 15 | MODERATE | The tallest peak was generated by PM10 fraction of pollutants. | ||
5th November | 41 | 24 | 5 | 13 | MODERATE | The main peak is dominated by PM2.5, although the last peak in that series was dominated by PM10. | ||
6th November | 54 | 29 | 8 | 12 | HIGH | EXCEEDANCE | The density of traffic here is increasing now that the roadworks in Faversham have cleared and drivers are no longer driving the 'long way round' to Sittingbourne and beyond. The dominant pollutant was from the PM2.5 fraction. | |
7th November | 58 | 30 | 6 | 15 | HIGH | EXCEEDANCE | The density of traffic here is increasing now that the roadworks in Faversham have cleared and drivers are no longer driving the 'long way round' to Sittingbourne and beyond. Both Exceedances were from the NO2 fraction of Pollutants | |
8th November | 66 | 35 | 32 | 10 | HIGH | EXCEEDANCE | Traffic levels are noticeably higher than in recent weeks - heavy traffic well into the evenings. The high pollution is a reasonable measure of what is "normal" for us in Teynham and Lynsted. But once we see Traffic throttling by Drain Repairs (starting January 2020) it will be interesting to see what happens to the mix of pollutants. The Exceedance was from the NO2 fraction of pollutants. | |
9th November | 74 | 38 | 33 | 10 | HIGH | EXCEEDANCE | EXCEEDANCE [12.01 - 13.11pm] |
Both peaks were from the PM2.5 fraction - only the first peak was an "exceedance" at "Very High" levels. |
10th November | 66 | 36 | 15 | 13 | HIGH | EXCEEDANCE | The "Very High" peaks were in the NO2 pollution fraction. These measurements were not an Exceedance at "Very High" levels as the periods were less than one hour continuous - 7.04-8.03am & 20.16-21.12pm). | |
11th November | 49 | 29 | 15 | 15 | MODERATE (see comment) |
This PM2.5 measurement is right at the margin, so I have placed it into "MODERATE" even though the App data identifies it as "HIGH". The dominant pollution was NO2. | ||
12th November | 46 | 25 | 34 | 14 | MODERATE | EXCEEDANCE [13.55-16.10pm] |
Exceedance was in the NO2 pollution fraction | |
13th November | 31 | 21 | 21 | 12 | MODERATE | EXCEEDANCE [12.20-14.05pm] |
The principle pollutant was in the PM2.5 fraction of Particulate Matter (very fine and most damaging). Map south of A2. However, the exceedance was in the NO2 fraction of pollutants (156 score).. | |
14th November | 21 | 20 | 24 | 13 | MODERATE | EXCEEDANCE [8.30-10.30pm] |
Exceedance was in the NO2 fraction. Otherwise the pollution was at the lower end of MODERATE. | |
15th November | 21 | 24 | 4 | 9 | MODERATE | The anomylous spike was NO2; other polutants are mainly PM2.5 and PM10 | ||
16th November | 38 | 24 | 28 | 14 | MODERATE | EXCEEDANCE 14.26-15.40 and 21.40-22.50 |
Two VERY HIGH NOx episodes of more than one hour = harmful. Map of jogging. | |
17th November | 57 | 32 | 14 | 13 | HIGH | EXCEEDANCE | Five minutes short of EXCEEDANCE at "VERY HIGH" for NOx. The whole day measured as "HIGH" for 24 hours (Exceedance) | |
18th November | 54 | 29 | 36 | 14 | HIGH | EXCEEDANCE | EXCEEDANCE 10.20-11.35 - second spike only |
The first NOx spike did not last an hour; the second did. |
19th November | 77 | 40 | 17 | 9 | HIGH | EXCEEDANCE | . |
For Information: NOx was raised in the afternoon but th main pollutant was PM2.5 |
20th November | 72 | 37 | 17 | 11 | HIGH | EXCEEDANCE | EXCEEDANCE 22.47- 23.52 . |
NOx Spike was an exceedance of 65 minutes - this is at the margins but still registers as "Exceedance". |
21st November | 84 | 44 | 28 | 12 | HIGH | EXCEEDANCE | Almost uniform HIGH levels of pollution all day. | |
22nd November | 81 | 42 | 14 | 20 | HIGH | EXCEEDANCE | Map of jog south of A2 - HIGH pollution throughout. | |

2nd January | 20 | 27 | 21 | 17 | MODERATE | Elevated levels across all four pollution fractions. NOx dominated between 7am-2pm; the sharp "High" peak at 6am was PM10 and PM2.5. The A2 drain-works did not materialise on this 'due date.' Rapid cycles in traffic impacted by flow through Bapchild - the worst of which may halt when Greenstreet roadworks come on stream. | ||
