Presentation Transcript

  1. Ch.1. Introduction • Environmental Geochemistry? • The application of chemical principles to predictethe fate of organic and inorganic pollutants at the earth's surface and in the atmosphere (R.Stoessel) • Applying geochemical knowledge to solve environmental problems

  2. Ch.1. • Some Concepts for EG • Earth is a closed but dynamic system It stays in the system but cycles through the system (e.g. rock cycle, water cycle, sulfur cycle, etc.) • Earth is practically the only home for human beings within our reach in the Universe • Need to balance development with conservation  Sustainability!! • Environmental impact may seem little before getting the critical point • A lot slower recovery than pollution, which is of course extremely expensive  Problems for generation after generation • Recovery (restoration, remediation) is never perfect. • Environmental Science is a comprehensive study field
