Research Abstract

In oder to get a significant data and an important discovery in the atmospheric chemistry study, the research project was carried out over North Atlantic Ocean as the cooperative program between Keio University in Japan and University of Rhode Island in U.S.A.
In smpling sites, Bermuda, Barbados and Canary Island over North Atlantic Ocean, air samples are continuously and regularly collected for three years at least, and then the chemical analysis of these aerosol samples(particles and gases) is done by using INAA, XRF, AAS, IC and LC methods.
The air sampling in Bermuda started on February 1989 and most of collected samples was already analyzed. The air sampling in Barbados has also started since March 1990. Aerosol samples have still been collected there, while these samples are not analyzed yet.
The investigation of analytical results of these samples collected in the sampling sites over North Atlantic Ocean is able to make clear the transport of not only air pollutans from North America and but also the dust from Sahara Desert to North Atlantic Ocean. These data are also important to explain the cycling of material between atmosphere and ocean.
