ABSTRACT
Air pollution of indoor environments is one of the biggest health concerns in the European region and around the world, because people spend indoors the most of their time (i.e. homes, offices, vehicles, restaurants, etc.). Thus, they are exposed to the different type of pollutants such as volatile organic compounds (VOCs), an important source of the poor indoor air and which has been associated with various adverse health effects. In this context, the aim of our experimental studies was to monitor the volatile organic compounds belonging to different chemical categories in indoor air of residential and office spaces located in urban area of Bucharest, Romania. The compounds, selected based on the effect they may have on the human health, were monitored by using the equipment with a photo-ionization detector (PID), that detects and records, in real time, the concentrations of compounds, in range 20 – 20000ppb, with a resolution of 1ppb. The findings of the monitoring activity revealed that in all analysed spaces there are volatile organic compounds, and the measured concentrations were compared with Occupational Safety & Health Administration (OSHA) Permissible Exposure Limits (PELs). The levels of VOCs concentrations are in OSHA PELs, but for same VOCs the values were higher than those reported in indoor air of Egyptian offices, for example. The exception is acrolein, an unsaturated aldehyde, whose recorded values were between 0.3 and 0.6ppm, exceeding for three to six times the permissible exposure limits (0.1ppm). The highest values for acrolein were found in the office with most occupants. For residential spaces, the concentration of acrolein was also over permissible exposure limit both in the bedroom and in the kitchen, the highest concentrations being recorded in residential areas 2 - bedroom and 3 - kitchen.
The main purpose of our monitoring studies was the awareness the health risks of poor quality indoor air and the necessity of action towards reducing existing pollution in indoor built environment.
