中文摘要：

Irgarol 1051是目前使用最多的海洋防污剂之一，已在世界范围内的自然水体中检测到Irgarol 1051的存在，并在新加坡海域检测到其在水环境中的最高浓度为4．2 mg·L－1．它的存在严重影响着非目标生物的生存和生长，且可改变生态群落的种群组成与丰度，严重威胁水生生态系统的健康和安全．本文对Irgarol 1051的主要性质、环境行为及其生态效应进行综述，以期为进一步研究打下基础．

英文摘要：

Irgarol 1051 is one of the most frequently used marine antifouling agents, which has been found in water environments worldwide, with the highest reported concentration of 4.2 mg·L-1 found in Singapore. The existence of Irgarol 1051 in natural water has serious impact on the survival and growth of non-target organisms, and can change species composition and abundance of biological community. Thus, Irgarol 1051 may be a serious threat to aquatic ecosystem health and safety. This paper reviewed the main properties, environmental behavior and ecological effect of Irgarol 1051;and may provide a foundation to the further study.
