Second-hand smoke in four English prisons: an air quality monitoring study

摘要

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/m3 and 5.9?μg/m3 respectively, p?
