Global environmental problems like air pollution from acidic substances are the most crucial concerns for humanity at present. These environmental problems are believed to be primarily caused by the use of large amounts of fuel that contain elements that cause the formation of acidic substances and also by ineffective combustion methods that promote the accelerative accumulation of acidic substances.
Acidification is still a major environmental problem.
I am personally very worried about acid snow and rain, the continuing degradation of waters and soils, destruction of forests, the deterioration in the regeneration of micro-organisms and microphytes, which limits the life of building materials such as concrete, iron, and marble. Stopping acid snow and rain is the main priority for people not only in Japan but also globally. In addition, I also hope that we can discuss effect-oriented strategies that can reduce emission and prevent environmental degradation. Participants from all over the world will attend this conference. I am especially pleased to note that there will be many participants from Eastern and Northern Europe, East Asia, North America, and from Africa.
