Electroanalytical Techniques for the Remediation of Heavy Metals from Wastewater

This book chapter summarizes the sources of heavy metals in water, treatment of wastewater, and diseases caused by polluted water due to heavy metals. Commonly, human interaction with heavy metal can occur through various routes, which include ingestion through food or drinks and inhalation of dust or fume. Heavy metals such as lead, mercury, copper, cadmium, zinc, nickel, chromium, and arsenic cause growth problems, nervous system damage, cancer, organ damage, and in extreme cases death. In recent years, both the type and content of heavy metals in water have gradually increased due to fast global development and human activities.
