Worldwide Application of Our Environmental Research
Air pollution will be the dominant environmental driver of premature human death in the near future, and aerosols are expected to be the most serious environmental problem. In many countries, in particular in the Asian region, which accounts for more than 60% of the world's population, the problem of air pollution is becoming more prominent due to factors such as the rapid industrial development without consideration for the environment. We think that Japanese environmental scientists should tackle this problem because Japan has grappled with serious air pollution problems for more than half a century and has a relatively clean atmospheric environment today.
GRiP-ACE Project
Our laboratory has conducted many international joint research projects and accepted many international students. International joint research studies have been conducted with the United States (University of Wisconsin-Madison), China (Tsinghua University, Xi'an Jiaotong University), India (National Institute of Physics), Malaysia (Putra University), Indonesia (Gajah Mada University), New Caledonia (Scal ' Air) and Croatia (University of Zagreb). International students have come from a variety of countries/regions, including China, Indonesia, Sweden, Spain, Uzbekistan, Korea, the United States, and Hong Kong. Based on these successful partnerships, we launched the GRiP-ACE (Global Research Institute of Pollution-control, Atmospheric Chemistry and Environmental Science) project in 2019. Utilizing the knowledge of environmental chemistry cultivated in this laboratory, we plan to conduct further research with the goal of contributing to global environmental improvement.

Toxicity Evaluation of Aerosol Particles Collected by Cyclone Sampler at India, China, and Japan
Numerous studies have pointed out serious air pollution problems in India and China. Recently, air pollution in China has started to be improved due to strong environmental measures, while India has yet to see significant air quality improvement. In line with our mission, we have installed our K-RiC in India and China. We have been conducting toxicity evaluation of aerosol particles collected in foreign cities, in addition to our university, here in Japan.

We have installed K-RiC at Xi’an Jiaotong University, China.
This is a PM2.5 sample collected using K-RiC. These aerosol particles, in powder form, are subjected to chemical analysis, biochemical analysis, and in vitro / in vivo exposure experiments, in order to conduct the toxicity evaluation.
Conventional filter sampling is also conducted to compare with our cyclone sampling.
