Environmental geochemistry applies chemical principles to assess how organic and inorganic pollutants behave in the Earth's system and atmosphere. This chapter highlights the importance of understanding cycles like rock, water, and sulfur to address environmental challenges. It emphasizes the dynamic nature of Earth as a closed system, where human existence depends on balancing development with conservation efforts to ensure sustainability. The chapter also discusses the slow recovery processes from pollution, raising awareness of long-term environmental impacts for future generations.

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
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
