地球環境に及ぼす人間の活動と質量分析の寄与

Abstract

The results of the conceptual study on the effects of human activity on the Earth's environment, classified into regional and global issues, are summarized. Pollution by various pollutants in air and water has been greatly improved since the 1970s in Japan, and the toxicity of dioxin has been found to be slight. The number of designated victims of pollution disease and the death rate of infants have been decreasing, and the average life span in Japan ranks among the top in the world. Based on these facts, regional environmental problems can be said to be insignificant. On a global scale, it was not possible to indicate the deterioration of the Earth's environment from the viewpoint of engineering because the reason behind global warming is unclear, the destruction of the ozone layer has been scientifically solved, and the exhaustion of natural resources cannot be certified through direct scientific evidence. These reasons suggest that the recognition that the environment is growing worse is possibly incorrect, and misguided efforts in the engineering field based on such assumptions will come to nothing. Rather, more attention should be paid to the diffusion of poisons in the environment in a recycling society, as it will possibly increase the load on the environment.
