Abstract
As a result of rapid economic growth in the East Asia, emission of anthropogenic substances has been increasing compared with other regions in the world. Air pollution in the Asian continent is more serious than that in Japan well controlled under the anti-pollution laws. In addition, the air pollution influences the remote area of the North Pacific far from the sources over the East Asia due to its long range transport. Natural substances such as mineral dust are modified their chemical and physical properties by reacting with anthropogenic substances and sea salt particles during the transport over the ocean. The denatured crustal substances may change marine ecosystems in the open ocean, e. g. HNLC (High Nutrient Low Chlorophyll) regions of the oceans will be affected by resulting in long range transport and deposition of crustal substances with anthropogenic substances.
