Lead in Plants and the Environment

This book examines the way that lead enters the biosphere and the subsequent environmental impact. The contributing authors include international experts who provide methods for assessing and characterizing the ecological risk of lead contamination of soil and plants. Information is provided on the consequences for human health as a result of lead pollution. This book reveals that approximately 98% of stable lead in the atmosphere originates from human activities.Lead in Plants and the Environment reports on methods for detecting, measuring, and assessing the concentration of lead in plants. The authors provide a method for the measurement of 210Pb isotopes in plants. This method can be applied extensively in different environmental settings, not only as a way of revealing sources of lead, but also as a way to monitor lead transport in plants and animals that ingest them.The chapters include coverage on the following topics:· Lead bioavailability in the environment and its exposure and effects· Radioanalytical methods for detecting and identifying trace concentrations of lead in the environment· Lead contamination and its dynamics in soil plant systems· Lead pollution monitoring and remediation through terrestrial plants in mesocosm constructed wetlands· A review of phytoremediation of leadThis book is a valuable resource to students, academics, researchers, and environmental professionals doing field work on lead contamination throughout the world.

Educates researchers and academicians who are working on lead contamination and remediation practices Describes isotopic as well as stable forms of lead, and its impact on plants and the environment Benefits graduate and undergraduate students specializing in radioecology and environmental sciences
