Sulphates, nitrates, and chlorides in particle fractions of different size.

This paper describes a pilot study of chloride, nitrate, and sulphate content in thoracic and high-risk respirable fractions of airborne particles. Samples were collected at one measuring site in Zagreb in autumn 1998 and spring 1999. The results showed that almost total chloride, nitrate, and sulphate content was present in the respirable particle fraction. The average mass contribution of these pollutants to the particle mass amounted to 25%. Although chloride mass concentrations were quite low, the findings indicated that all pollutants originated from the same source.

Levels of nitrogen dioxide in the Zagreb air.

Surveillance of NO2 in Zagreb started in 1994 at five measuring sites. This paper presents the levels and trends of NO2 annual mean values for the period between 1994 and 1998. The obtained data are compared with the recommended and limit values according to the Law on Air Quality Protection in Croatia and the Ordinance on Recommended and Limit Air Quality Values. For the past five years, ever since the measurement commenced, the concentration levels of NO2 in Zagreb have kept between the national recommended and limit values at all measuring sites, indicating that the air has been moderately polluted. This paper also shows the variations of monthly mean values through 1998 at all sites. The levels of NO2 in the northern part of Zagreb were measured at two distances from traffic. Daily variations in the levels were measured near the road and presented as hourly averages for workdays and weekends in winter and in summer reflecting the activity pattern of emission sources.

Air pollution studies.

The aim of this paper is to give an overview of the research in the area of air pollution, carried out exclusively at the Institute for Medical Research and Occupational Health and performed by the scientists of the Institute. For the past fifty years, air quality has been studied at work, in the ambient air of urban and industrial areas, and in various indoor environments without occupational exposure. Methods for sampling and measuring air pollutants have been introduced or developed and verified. The behaviour and the fate of air pollutants in the environment have also been investigated. Since the primary goal of the studies was to assess the extent of human exposure to air pollutants, the data were used to calculate the risk for various population groups. A dynamic model of exposure for various population groups relied on calculations of collected data, taking into account time spent in various microenvironments. This text describes the cooperation of the Institute with other institutions and agencies on the national and international level and outlines the current and prospective activities.
