Phosphorus Pollution Control - Policies and Strategies
Deterioration and decline of water resources due to pollution caused by humans and their activities has become a universal health, environmental, social and economic problem. Excess discharges of nutrients, in particular, phosphorus, has been recognized as the most prevalent water pollution problem globally. Moreover, its perpetual occurrence and expansion creates imminent threats to water and food security.
Despite extensive research during the past five decades, many key questions in eutrophication science remain unanswered. This book summarizes the most recent policies and strategies for phosphorus removal and recovery from municipal, residential and agricultural wastewater effluents and runoff into a concise and up-to-date volume. The book will be of interest to environmental and water resources scientists and engineers, consultants, policy makers, and practitioners working in the field.
