The effects of air pollution on climate, the environment, and human health have become a major research trend in atmospheric and epidemiologic science, and are the focus of this Special Topic.

The 10-year papers are dominated by health and epidemiological studies. These studies examine the link between particulate air pollution and cardiovascular and pulmonary morbidity and mortality. Particulates including sulfates, ozone, airborne toxins, and polycyclic aromatic hydrocarbons are all discussed. Other notable studies in the 10-year list include the suppression of rain and snow by urban and industrial air pollution, the transport patterns of air pollution from Asia to North America, and the various methods for measuring air quality.

Health effects remain a research focus in the 2-year list, but there is also a noticeable trend towards other studies, predominantly air-quality studies. Results are presented for both the 2000 Texas Air Quality Study as it pertains to ozone pollution over Houston and the 2002 New England Air Quality Study. Air-quality testing modules, such as the Canadian Aerosol Module and the Community Multiscale Air Quality model, are discussed. Global patterns of air pollution, including trans-Pacific transport of particulates and the role of the North Atlantic Oscillation in particulate movement, are studied. One study examines the difference between weekday and weekend air pollution in southern California. Health-related studies in the 2-year list include those examining the possible effects of air pollution on children with asthma, the human macrophage response to ultrafine, fine, and coarse particulates, and a study in mice which shows that a reduction in pollution correlates with a reduction in genetic mutations.


To construct this database, papers were extracted based on title-supplied keywords for Air Pollution. The keywords used were as follows:

The baseline time span for this database is 1995-2005 (second bimonthly). The resulting database contained 5,026 (10 years) and  1,371 (2 years) papers; 10,710 authors; 87 countries; 898 journals; and 3,052 institutions.


Once the database was in place, it was used to generate the lists of top 20 papers (two- and ten-year periods), authors, journals, institutions, and nations, covering a time span of 1995-2005 (second bimonthly: ten-year plus four-month period).

The top 20 papers are ranked according to total cites. Rankings for author, journal, institution, and country are listed in three ways: according to total cites, total papers, and total cites/paper. The paper thresholds and corresponding percentages used to determine scientist, institution, country, and journal rankings according to total cites/paper, and total papers respectively are as follows:

Entity: Scientists Institutions Countries Journals
Thresholds: 12 31 15 9
Percentage: 1% 1% 50% 10%
