The Results Are In: Dangerous Levels of Air Pollution In Castle Ward













                                                                                                                                                                                                                                                                                            As reported in the Colchester Gazette, here are the full set of results from our diffusion tube testing of nitrogen dioxide traffic emissions in Castle Ward. We have done this testing to add to the Council's own testing results rather than to compete with them and we fully encourage people to use both sets of results. Our findings are more positive for Brook St residents as the emissions are lower than on the Council's 2016 set of statistics. However they are very concerning for those living near East Street and North Station Road. The concentration of an air pollutant (eg. Nitrogen Dioxide) is given in micrograms (one-millionth of a gram) per cubic meter air or µg/m3. NO2 levels should be within a 40 ug/m3 annual legal limit.


1) Outhouse East, East Hill - 36.22
2) Brook Street (Near Number 71) - 34.52
3) Brook Street (Bottom End Near Traffic Lights) - 37.84
4) Queen Street- 34.72
5) St Botolphs Street- 52.72
6) East Street near Ipswich Road turning - 60.74
7) North Station Road - 58.02
8) East Street - 52.76
9) Colchester High Street - 37.10
10) Top end of East Hill (Oyster House) - 44.17
