2012 Noise and dust survey

When these results are compared with the Environment Agency’s Environmental Assessment Level (EAL) for nuisance dust of 0.1 mg/m3, they all come out quite high. Earith & Haddenham have the lowest average at 0.05 mg/m3, then Cottenham at 0.08 mg/m3 & Wilburton at 0.1 mg/m3 (on the EAL). Hilton averages 0.58 mg/m3, but there is one potential rogue result which should be removed, returning the average to 0.1 mg/m3.
The current recommendation by the HSE of how to interpret the Workplace Exposure Limits from which the EALs are derived, is that action should be taken if the exposure exceeds 40 % of the limit.
Earith & Wilburton are exposed to 50 % of the EAL by the roadside, Cottenham similarly 80 % of the EAL, and Wilburton & Hilton 100 % of the EAL.
These are only single day results, and the dust level may be higher at other times, which may account for the high result at Hilton (G9561). It should still be concluded that roadside dust in the villages is too high.
