| Research Abstract |
Studies concerning the establishment of new air pollution monitoring system were conducted during four years aiming to clarify the purpose of air monitoring based on field observation covering both in Kanto and Kansai areas. Air pollution trend analysis, wind tunnel study, field monitoring, model analysis were used. Trend analysis of air pollution monitoring data during 30 years showed that air pollution level increasing in the outside of big city area in comparison with downtown area. Annual average of oxidant concentration has been increasing.
It was also found that frequency distribution of middle range concentration, 40-60ppb, has been increasing comparing with low and high level range of oxidant. Annual trends in oxidant and wet deposition at Matsue National Air Severances Network station are also increasing. The Matsue station is less polluted remote area, and this indicates the necessity of wide aerial monitoring network covering China main land.
Automatic VOCs monitoring system has established to investigate the hydrocarbon species. Comparison study between Tokyo Metropolitan Area and Mexico City were conducted. It was found that concentrations of propane, propylene and butane in Mexico City were 10-30 times higher and acetylene was 10 times higher than that observed in Tokyo. These results indicate the usefulness of automatic VOCs monitoring system to estimate the weight and role of LPG and mobile sources in Mexico City area.
Research prospects of monitoring system for emission characteristics and environmental behavior of airborne fine particulate matter were also discussed.
