This book, edited by De-Sheng Pei and Muhammad Junaid, emphasizes that the oceans are a vast but fragile resource that must be protected if we want to protect our livelihoods and our planet. Although marine pollution is a topic of concern for a long period of time, it has recently attracted the significant attention of scientific and non-scientific debate circles, including environmentalists, economists, and politicians. The chapters on methods to assess pollution provide important information for identifying, measuring, and remediating various pollutants, while the chapters on known pollutants and their management point out how widespread the problems are and how intense international effort is required to resolve the problems.
