The development of easier, cost-effective and quicker methods to evaluate POPs persistent organic pollutants in developing countries is long overdue. The easiest possible method is to use suitable bioindicators. All those who are involved in the monitoring of POPs - the policy makers, scientists, research students, laboratory technicians, university students and nongovernmental institutions - need a book such as this one at present. This timely book was designed primarily as a broad treatment of this discipline which would be accessible to almost all the people working on POPs. This will be the first book that is exclusively dedicated to Bioindicators of Pollution by POPs .
