| Research Abstract |
In order 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 sampling sites, Barbados and Canary Islands over North Atlantic Ocean, air samples were continuously and regularly collected for one year at least, and then the chemical analysis of these aerosol samples (particles and gases) was done by using INAA, XRF, AAS, IC and LC methods.
The air sampling in Barbados started on March 1990 and most of collected samples was already analyzed. On the other hand, the air sampling in Canary Islands also started from March 1991.
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 pollutants 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.
