Since the publication of the third edition of Aquatic Pollution in 2000, there have been many major developments within the field in terms of research, regulations, and also large-scale catastrophes that have had a significant impact on the aquatic environment; the Deepwater Horizon oil spill and the Fukushima nuclear disaster have taken their toll, and research on ocean acidification has developed enormously over the last decade. Recognizing, controlling, and mitigating aquatic pollution on a global scale is one of the most important and most difficult challenges facing society today.

Fully updated to reflect current understanding and discussing these major recent developments, this fourth edition of Aquatic Pollution covers every aspect of pollution associated with urban runoff, acid rain, sewage disposal, pesticides, oil spills, nutrient loading, and more. Case studies of major pollution sites, all original to this new edition, help to illustrate points made in general discussion.

Offering unprecedented depth of coverage, and discussing both fresh and sea water environments, this unique text provides a key teaching and learning tool for courses in environmental science, zoology, oceanography, biology, and civil or sanitary engineering, as well as a vital book for government policy makers. It is also an excellent primer for policymakers and activists focused on environmental issues.
