Indoor concentration levels of selected pollutants and household characteristics.

As part of a large health effect-related human exposure study conducted in the city of Zagreb, Republic of Croatia (Sega and Fugas, 1987), NO2, NH3, HCHO, and settled dust concentrations were measured during winter and summer periods in the kitchens and living rooms of 90 homes throughout the city. Characteristics of households and household members were recorded and correlated with the pollutant concentration levels. The results indicate that household characteristics may be useful for predicting human exposure to air pollutants.
