Amazon.com description: Product Description: This new edition provides a balanced account of what wastes are discharged into the sea or get there accidentally, what happens to them when they get there, the effect they have on the marine environment, and the threats they present to human health. As well as being completely updated, case histories have been replaced by more recent ones, and the whole book has been given a greater international emphasis. This new edition has a new chapter to explain techniques for measuring change in the marine environment, extended further reading, and more emphasis on tropical seas. It is designed as an introductory text but no particular knowledge is demanded of the reader; it can be used by engineers, economists, lawyers, or environmentalists who need to be informed about the effects of materials that are deliberately or accidentally discharged into the sea.
