§ Mr. RedmondTo ask the Secretary of State for Health if he will list by year for the last five years, the percentage of people who have suffered health problems from airborne emissions of(a) lead, (b) carbon monoxide and (c) particulates.
547W
§ Mr. FreemanExcept for instances of massive accidental exposure or deliberate self-exposure to carbon monoxide the informaton is not available. The effects of airborne emissions of lead, carbon monoxide or particulates currently experienced cannot be isolated from many other factors unrelated to air contaminants but contributing to health problems. Concentrations of these pollutants in the air are monitored at critical sites and, in general, they fall within the limit values prescribed under EC directives or the guidelines proposed by the World Health Organisation. Where these limit values or guidelines are exceeded occasionally, the measured levels have been within the recognised safety margins.
