Advancements in the transport and transformation of amines in the marine environment

Abstract:

In the atmosphere, amines play potentially important roles in climate change, which is a hot spot of the current international research. The ocean is an important source of amines in the atmosphere; however, the mechanism of the formation of amines in the environment has not been elucidated due to the difficulty of detecting amines in seawater. This article outlines the concentration characteristics of amine precursors in marine organisms and their impact on amines in the marine environment; summarizes the concentration characteristics of amines in sediments, seawater, and the atmosphere; analyzes the formation pathway of amines in marine atmospheric particles; and identifies the difficulties in the detection of amines in seawater and the related problems that need urgent attention. This study provides insights into the transport and transformation of amines in the marine environment and the resulting climatic effects on the marine atmosphere.
