To measure levels of indoor pollution in relation to smoking in four English prisons.
TSI SidePak AM510 Personal Aerosol Monitors were used to measure concentrations of particulate matter less than 2.5 μm in diameter (PM2.5) for periods of up to 9 h in selected smoking and non-smoking areas, and personal exposure monitoring of prison staff during a work shift, in four prisons.
PM2.5 data were collected for average periods of 6.5 h from 48 locations on 25 wing landings where smoking was permitted in cells, on 5 non-smoking wings, 13 prisoner cells, and personal monitoring of 22 staff members. Arithmetic mean PM2.5 concentrations were significantly higher on smoking than non-smoking wing landings (43.9 μg/m(3) and 5.9 μg/m(3) respectively, p < 0.001) and in smoking than non-smoking cells (226.2 μg/m(3) and 17.0 μg/m(3) respectively, p < 0.001). Staff members wore monitors for an average of 4.18 h, during which they were exposed to arithmetic mean PM2.5 concentration of 23.5 μg/m(3).
The concentration of PM2.5 pollution in smoking areas of prisons are extremely high. Smoking in prisons therefore represents a significant health hazard to prisoners and staff members.
测量英国四座监狱中与吸烟相关的室内污染水平。
在四座监狱的选定吸烟区和非吸烟区，使用TSI SidePak AM510个人气溶胶监测仪测量直径小于2.5μm的颗粒物（PM2.5）浓度，测量时长最长为9小时，并在工作班次期间对监狱工作人员进行个人暴露监测。
从25个允许在牢房内吸烟的侧翼楼梯平台的48个地点、5个非吸烟侧翼、13间囚犯牢房收集了平均时长为6.5小时的PM2.5数据，并对22名工作人员进行了个人监测。吸烟的侧翼楼梯平台的PM2.5算术平均浓度显著高于非吸烟的侧翼楼梯平台（分别为43.9μg/m³和5.9μg/m³，p<0.001），吸烟牢房中的PM2.5算术平均浓度也显著高于非吸烟牢房（分别为226.2μg/m³和17.0μg/m³，p<0.001）。工作人员佩戴监测仪的平均时长为4.18小时，在此期间他们暴露于PM2.5算术平均浓度为23.5μg/m³的环境中。
监狱吸烟区的PM2.5污染浓度极高。因此，监狱吸烟对囚犯和工作人员均构成重大健康危害。
