Progress in Research on Sources and Removal Methods of PAHs

Abstract

The exploitation of natural resources and the rapid development of the economy have brought us great material wealth. The standard of living of the people has been renewed both materially and spiritually, but at the same time it has also caused excessive consumption of resources and the continuous deterioration of the ecological environment. Studies have shown that 70% to 90% of human cancers are caused by environmental carcinogens, or are closely related to environmental factors. Among environmental pollutants, the most difficult for human beings to deal with are substances that cannot be fully degraded by staying in the environment for a long time, cannot be degraded in living organisms and remain for a long time to poison them, can be transferred over long distances and are strongly toxic, and these problems have received widespread international attention.
