Abstract
Levels of gas and particle-phase substances present in the indoor air at non- industrial sites in Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama; including offices, hospitals and restaurants, were measured dur ing 1993 and 1994. Samples collected at 40 sites were analysed for respirable suspended particles (RSP, d50 <3.5 μm), ultraviolet RSP (UV-RSP) as a mark er for environmental tobacco smoke, carbon monoxide, carbon dioxide, and nicotine. Levels of RSP were very high at several sites, varying within the ranges of 34-421 μg/m 3 in restaurants, 21-242 μg/m3 in hospitals and 13- 196 μg/m3 in offices. Carbon monoxide levels were also high at several sites with peak concentrations reaching 29, 20, and 19 ppm, respectively, in an office, a hospital and a restaurant. Infiltration and penetration of outdoor pol lutants into the indoor environment occurred at all sites studied.
