Environmental Chemistry is part of the Cambridge Modular Sciences series for A and AS levels. It builds on the material introduced in Foundation Chemistry and provides an introduction to the chemical processes that occur in the environment, with reference to natural reactions and the effects of pollution. It promotes an awareness and understanding of the contribution of chemistry to environmental issues. To help students with study and revision, there are self-assessment questions throughout the text, a list of learning objectives at the start of each chapter and a summary of contents at the end. Structured and essay questions also appear at the end of each chapter.
