The Study of Remediation Standards of Heavy Metal-Cu Contaminated Soil Based on Risk Assessment

Abstract

This paper describes the model of heavy metal-Cu contaminated soil remediation standard value based on risk assessment. In the Cu contamination risk assessment model, the main exposure methods are oral ingestion and inhalation through breathing, which not only simplifies the calculation but also make people get a clearer understanding of the way of Cu contamination. We get the simplified formula, calculate and discuss Cu contaminated soil remediation target value in specific parameters to provide reference and basis for the remediation of Cu contaminated soil.

Regulation Effect of Porous Materials on Soil Quality in Farmland

“…Moreover, affected by the properties of raw materials, preparation conditions, application amount and other factors, the remediation effects of porous materials are also different. In particular, for the modification of different porous materials combined with various methods to improve the quality of soil physical and chemical properties and the long-term stability of the effect need to be further studied [2].…”
