The paper discusses a battery-powered PM-10 indoor air sampler applied to unvented Third World residential combustion sources. The limited availability of reliable electric power away from the main towns meant that battery-powered systems were needed to collect integrated samples of the actual indoor exposure. The samplers incorporate horizontal elutriator PM-10 inlets and 8 by 10 in. (20 by 25 cm) filters for large sample capacity at low system pressure drop. A requirement for an integrated 24-hour sample meant that the usual Ni-Cd battery of the 4 L/min personal sampling pump was replaced by a Pb-acid gelled-electrolyte unit. These samplers, which have been used to develop emissions, chemical and bioassay data for coals from several mines as well as emissions variability within each coal type, are described and typical data collected are presented. A new version using a 12 L/min pumping system is also described.
