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

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

Air Quality Indicator
(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!

Flow 2 Map: Air pollution changed travelling eastward and westward on A2. May arise from air conditioner setting (recycle?), vehicles ahead are more polluting, bonfires have been lit? Detailed Map. Unresolved

Flow 2: Graph: Clean-air south of Lynsted village but interesting as it shows peaks near the A20 (morning and midday) and don't forget housework as a source of pollution (afternoon peaks). The mapping feature may have lost satellite links to give the odd pattern?
14 May Flow 1 Greenstreet Flow 2 Kingsdown	10 4	25	4 5	14 12	MODERATE LOW			Graph & Map: Wind: ENE - N - ENE (17kph). Dry and sunny. Graph: Mapping clitch but away from the A2, the clearer air is evident. The pollutant distribution mirrors Flow 1.

22 May Flow 1 Greenstreet Flow 2 Kingsdown to A2 Map	13 28	21	7 6	14 10	MODERATE			Graph: Wind: NW - S - SW (11kph). Rain 0.30 (overnight). Steady levels & peaks in 'usual places' - 2-3am (lorries), morning and evening rush hours and lunchtime. Flow 2 Map: High pollution from the M2 through Lynsted Village. The wind had veered bringing a concentrated pollution event.

24th May Flow 1 Greenstreet Flow 2 Kingsdown	18	18 .	6 3	14 13	LOW MODERATE			Graph. Wind: WSW - NW - N - W (7kph, light eddying wind in evening); Rain: 1.2mm. The first A2 GREEN DAY in over three months! Two peaks - a spike when lorries got stuck; a period around the school run. Flow 2: Outward and return journeys show same variability in pollution spikes on A2.

25th May Flow 1 Greenstreet Flow 2 Kingsdown	37	24	9 2	13 14	MODERATE "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. Flow 2: A2 shows as polluted while most countryside was Green
25th May Flow 1 Greenstreet Flow 2 Kingsdown	11	26	9 2	13 14			Exceedance:- 11.30am - 14.10pm - PM2.5 -
26th May Flow 1 Greenstreet	14	20	3	16	MODERATE			Graph: Wind: WSW - W - WNW (18kph). Rain: 4.70mm. Periods of "Low" pollution and a spike of High (traffic got snarled up) then bumped along after 15.00pm.
27th May Flow 1 Greenstreet	20	27	7	12	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.
28th May Flow 1 Greenstreet Flow 2 Kingsdown	14 .	20	12	11	MODERATE			Graph: Very close to "Low" - a good day to enjoy strenuous exercise! Wind: W - NW - NNE - E (15kph). Rain: 6.50mm

NO MEASUREMENTS MADE IN AQMA5 between 28th September and 18th October
18th October	18	23	2	13	MODERATE
19th October	11	23	2	13	MODERATE			PM10 was the dominant fraction throughout.
20th October	14	31	6	8	MODERATE			PM10 was the dominant pollution fraction with raised PM2.5 during the morning peaks.
21st October	11	28	14	10	MODERATE		EXCEEDANCE [20.00-21.20pm]	NO2 peak of "Very High" Exceedance in the evening. The period quoted only covers the period with evidential data (there was a break in power that is excluded from the calculation)
22nd October	20	30	14	13	MODERATE			PM10 dominant fraction with the exception of the "very high" peak of NO2 - the last peak of the day.
23rd October	20	26	5	12	MODERATE			PM10 pollution fractions dominated all day with slightly elevated PM2.5 in the evening.
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
26th October	13	28	2	13	MODERATE			PM10 makes up nearly all the pollution fractions.
27th October	16	22	5	10	MODERATE			This Map link illustrates spread of pollution south over the lanes..
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.
23rd November	54	33	9	21	HIGH	EXCEEDANCE		The midday peak (PM10) coincided with peaks of PM2.5 and NOx .
24th November	35	27	5	21	MODERATE			PM2.5 component dropped during the afternoon after high levels earlier. Also mapped jogging.
25th November	24	24	2	20	MODERATE			8am 5-vehicle pile-up on M2 Junction 5 (A249).. This accounts for earlier pulses of high pollution.
26th November	16	20	0	19	MODERATE			Right at the margins with "LOW" PM2.5 and VOCs. .
