This texbook shows environmental, scientists, engineers, and students how to examine a water pollution problem and methodically investigate and solve it. It describes the nature and properties of water and defines water pollution and its categories. The book stresses the source, pathway, and sink concepts of representative contaminants. The book's practical examples and common situations reinforce a fundamental understanding of the biological effects of pollution. The book focuses on bacteria and algae to show their importance as pollution indicators as well as their role in natural purification. Chapters inform you on basic environmental concepts related to food webs and contaminant transfer, population dynamics, and the structure of natural ecosystems. For students and professionals who have a background in basic vertebrate zoology and botany, this book broadens their knowledge of the biologic effects of water polution. | Specific types of pollution are addressed, including representative types of contamination scenarios. With this book, you can identify typical or expected patterns associated with water pollution and the potential effects on the biotic and abiotic components of the ecosystem.
