We have been researching the net to find a company to take an independent assessment of the pollution problem, noise will be dealt with separately.

We came across the following, it’s from the following website dustscan.co.uk it was started and run by a professor and several other senior lecturers from university’s around the country all experts in the environment with regards to dust, and they went on to develop systems and equipment that can give accurate readings on air quality. They also carry out assessments with real time gathered data.

They have a long list of major clients in this country including the government’s environment agency.

This is what they say about dust particulates

Dust is generally produced by mechanical action on materials and is carried by moving air when there is sufficient energy in the airstream. More energy is required for dust to become airborne than for it to remain suspended. Dust is removed through gravitational settling (sedimentation), washout (for example during rainfall or by wetting) and by impaction on surfaces (e.g. on vegetative screening). Dust can be re-suspended where conditions allow, such as from bare ground.

Dust propagation

Dust propagation through air is influenced by many factors including particle size, wind energy and disturbance activities. Large dust particles generally travel shorter distances than small particles. It is often considered that particles greater than 30 µm will largely deposit within 100 metres of sources, those between 10 – 30 µm to travel up to 250 – 500 metres and particles less than 10 µm to travel as far as 1 km or more from sources. These distances may be exceeded.

What can be determined from this statement is that M10 particulates and the more dangerous M2.5 particulates can travel far enough without excessive wind being calculated in, to embrace all of Northwich road and part of new plat lane, part of goostrey lane, kings lane, middlewich road, oak tree lane, all of the needham drive estate byley lane, basically all the properties from the A50 up to the motorway

Parts of Holmes chapel that lie within 1 kilometre from the motor way are Ravenscroft, Jodrell close, Manley close, Broad lane, Coniston drive, Chester road ,Middlewich road, Furness close, Thirlmere close, Cavendish way, Ingleton close, Edenhall close, Helton close

Particle size of M2.5 is the most dangerous its easily absorbed into the lungs and indeed blood stream , and has been linked to not only cardiovascular problems but cancer related diseases in various parts of the body. The very young and the older people being most at risk this is what the world health authority state.

The particulates are generated from car and HGV exhaust emissions, brake lining wear, tyre wear, and road surface wear.

What do the highways England propose to do about this ?

Remember if you don’t keep the pressure then the chances of them doing anything is slim to none!
