Abstract:

In recent years, the number of engineering projects for remediation of contaminated sites in China has been increasing rapidly. During implementation of these projects, the issue of secondary air pollution occurring in remedying pesticide chemicals polluted sites is attracting more and more concerns. Sources of VOCs in remediation of contaminated sites were analyzed, and scientific efficient management of the remediation projects was put forward as the major means to block the source of secondary air pollution from releasing pollutants into the air. Shortcomings in implementation and management of these projects in the country were also analyzed. Advancements in the study on and management measures of the issue in China and other countries were reviewed.

Key words: volatile organic contaminants (VOCs), contaminated sites, secondary pollution, remediation project
