§ Mr. Kinnockasked the Secretary of State for Wales how many grit and dust monitoring stations similar to those in Monmouth shire have been established in other areas of South Wales, and where are they located.
§ Mr. Peter ThomasThirty-four, as follows:
Aberdare … 4 sites Aberthaw … 7 sites Cardiff … 4 sites Gelligaer … 1 site Llantrisant … 1 site Merthyr Tydfil … 3 sites Mountain Ash … 4 sites Pontypridd … 1 site Port Talbot … 3 sites Swansea … 6 sites
§ Mr. Kinnockasked the Secretary of State for Wales what materials have been found in the solid particles collected at the six dust monitoring gauges in Monmouth shire where more than 200 milligrammes per square metre were recorded in the atmosphere.
§ Mr. Peter ThomasComprehensive information on this subject is not available. I will write to the hon. Member further on this.
§ Mr. Kinnockasked the Secretary of State for Wales if he will list in the OFFICIAL REPORT the readings at each of the six dust montitoring guages in Monmouth shire where more than 200 milligrammes per square metre of solid material were found in the atmosphere.
§ Mr. Peter ThomasFor the latest period available the average daily readings of grit and dust for the stations in question were as follows:
- Bishton Station No. 1–343 milligrammes per square metre.
- Magor & St. Mellons No. 1–422 milligrammes per square metre.
- Llanmartin No. 1–201 milligrammes per square metre.
- Nash No. 1–292 milligrammes per square metre.
- Ebbw Vale No. 1–638 milligrammes per square metre.
- Ebbw Vale No. 6–482 milligrammes per square metre.
The readings at these guages are highly localised and may be affected by factors 245W such as the volume of traffic in the vicinity and the proximity of road works. They should therefore be interpreted with caution and in the light of local conditions.
