About this book

The threat posed by toxins from cyanobacteria to water supplies has increased world-wide during the past 30 years. Health problems attributed to the presence of such toxins in drinking water have been reported in a number of countries, including Australia, Brazil, China, England, South Africa and the USA. This book, which has been prepared by an international group of experts, examines the need to protect drinking water and other water supplies from contamination by toxic cyanobacteria and to control the impact of such bacteria on health. It discusses the nature , diversity and global occurrence of toxic cyanobacteria, their consequences for public health, and methods for the assessment, management, investigation and treatment of contaminated water supplies. Programmes for monitoring the causes and occurrence of cyanobacteria in water and techniques for the analysis of water samples are described. This book will be an invaluable source of information for environmental health officers and professional in the field of water supply, fresh water ecology, public health and health education, as well as students and consumer groups.
