Abstract
Indoor air pollution by asbestos, from airborne particles following the cleaning of asbestos tiles and from water discarded after such cleaning, have been recognized as environmental problems. In this studs we measured concentrations of asbestos and airborne particles from asbestos tiles duting ±y floor cleaning and analyzed water discarded after wet floor cleaning. In addition, concentrations of volatile organic compounds (VOC) after floor coating were measured. The results demonstrated low concentrations of asbestos and airborne particles after city cleaning in the case that floor coating was properly maintained. However, there were high concentrations of biochemical oxygen demand, chemical oxygen demand, suspended solids and lead compounds in the discarded water, and high VOC concentrations after floor coating without adequate air ventilation. To avoid health disorders associated with VOC after floor coating, continuous air ventilation at a rate of 6.8 times per hour for longer than 8 hours is highly recommended.
