Distributions of long-term household exposure to ammonia

Details how distribution of exposure to ammonia in livingrooms were calculated by use of Duan s Cartenisation method for four population groups of Zagreb inhabitants (high school students, university students, employed and retired), for summer and winter periods. Households were grouped in two categories, city centre and suburbs. The main difference between these two categories was the so-called green areas (parks, gardens etc.) in the neighbourhood. The exposure levels are lower in the city centre compared to the suburbs. The results show seasonally dependent contribution to exposure in households from outdoor sources by ventilation in suburbs. Exposure distribution functions could be represented by normal, or summation by proportion of normal, Weibull and Erlang distributions. Concludes that by the comparison of the results and proposed guideline value, it could be argued that no ammonia exposure problem exists in Zagreb.
