Description
Soil contamination with heavy metals like Cr, Co, Cu, Ni, Mn, Cd, Pb, and Zn is becoming a main problem across the globe especially in developed countries. Globally, it has become a serious threat to human health and ecosystem integrity. applying amendments like phosphate compounds, liming materials, clay minerals, coal fly ash, organic composts, metal oxides, and biochar to heavy metals contaminated soil is considered one of the most promising in-situ remediation techniques. Biochar has become one of the most attractive research hotspots as a result of its special properties along with its important role in the climate change, global biogeochemical cycle and environmental system.This book will summarize recent progresses in understanding (a) metal-biochar interactions in soils, (b) potential risks associated with biochar amendment and (c) application of biochar for the remediation of HM polluted soils. In addition, research gaps and future directions in understanding biochar-metal interactions in soils will also be explored.- Enables readers to understand the most recent developments surrounding metal-biochar interactions in soils and their impact on agricultural productivity- Provides the latest statistics and literature review regarding the role of biochar in remediation of heavy metals polluted soils- Examines the global status of heavy metals polluted soil
