Conclusions
Hereby given the first comprehensive analysis of scientometric data on the subject of air pollution, it can be said that scientific interest in this topic has steadily increased to the present day. However, there is to be noted a major
research gap in terms of medical analysis. The major contingent of data originates from the USA and an even larger amount is written in the English language. Considering research quality as measured in terms of average
citation, less productive countries such as the Netherlands and Sweden show the best results. A generally larger effort towards medical research into air pollution is strongly indicated at this time.
