The UK Health and Safety Executive, in conjunction with the Department of the Environment, has carried out a number of surveys of airborne asbestos fibre concentrations in buildings. All samples have been collected on membrane filters and analysed by analytical transmission electron microscopy. Four categories of buildings under normal occupation have been investigated; non-domestic buildings containing sprayed or trowelled asbestos, domestic buildings containing sprayed asbestos or asbestos plaster, buildings with warm air heaters containing asbestos and buildings without asbestos materials. A number of buildings have also been surveyed during and after the removal of asbestos materials. The choice of measurement indices and analytical procedures is reviewed, before measurements are compared in terms of the concentration of asbestos fibres greater than 5 microns long. The decision whether to remove asbestos from occupied buildings is discussed with reference to the associated cost and risk. In the present survey, management of undamaged asbestos appeared preferable to large-scale removal.
英国健康与安全执行局与环境部联合开展了多项针对建筑物空气中石棉纤维浓度的调查。所有样本均采集于膜滤器上，并通过分析透射电子显微镜进行分析。已对四类正常使用的建筑物进行了调查；含有喷涂或抹刀涂抹石棉的非住宅建筑、含有喷涂石棉或石棉灰泥的住宅建筑、装有含石棉暖风机的建筑以及无石棉材料的建筑。在去除石棉材料期间及之后，还对一些建筑物进行了调查。在根据长度大于5微米的石棉纤维浓度对测量结果进行比较之前，对测量指标和分析程序的选择进行了审查。参照相关成本和风险，讨论了是否要从有人居住的建筑物中去除石棉的决定。在本次调查中，对未受损石棉的管理似乎比大规模清除更为可取。
