Chemistry of the Environment [PDF ebook] 

Chemistry of the Environment, 3rd Edition, is a concise, clear and current account of today’s environmental issues and the science one needs to understand them. This intermediate-level text, which recommends General Chemistry as a prerequisite, systematically lays out themes of sustainability, atmosphere, hydrosphere, lithosphere and biospheres, while stressing the interconnectedness of environmental problems and solutions. The completely revised third edition explains the natural chemical cycles, and how humans affect them. It also analyzes strategies for ameliorating human impacts. This stimulating new text uses concise, straightforward language and an accessible narrative style to inform quantitative thinking.
