中文摘要:

      大气中的有机胺具有潜在的气候效应，这是当今国际的研究热点之一。海洋是大气中有机胺的重要来源，但由于海水中有机胺检测难度较大，导致海洋环境中有机胺的产生机制尚不清楚。本文概述了海洋生物体内有机胺前体物的浓度特征及其对环境中有机胺的影响，阐述了沉积物、海水及大气中有机胺的浓度特征，分析了海洋大气气溶胶中有机胺的形成途径，并指出海水中有机胺检测的难点及现阶段亟待解决的科学问题。为深入认识海洋环境中有机胺的迁移转化规律及其潜在气候效应提供科学依据。

英文摘要:

      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.
