摘要

捷克孟德尔南极站(JGM)位于南极洲詹姆斯罗斯岛北部，为地理学、地质学、气候学和生物学等许多科学学科提供了研究设施。2015年，其活动扩展到塑料测试。当合成聚合物(通常称为塑料)暴露在室外条件下时，由于吸收入射的太阳紫外线辐射以及随之而来的与氧的反应，它们会发生不可逆的变化。它们在室外应用的稳定性和可靠性通过世界各地的风化测试。直到2015年，当JGM开始对塑料进行系统研究时，还没有关于塑料对南极气候的抵抗力的信息。

Antarctica – A unique location for the testing of polymers

The Johann Gregor Mendel Czech Antarctic Station (JGM), located in the northern part of James Ross Island in Antarctica, provides a facility for research in many scientific disciplines, such as geography, geology, climatology and biology. In 2015 its activities were extended by the testing of plastics. When synthetic polymers, often referred to as plastics, are exposed to outdoor conditions they undergo irreversible changes due to the absorption of incident solar UV radiation and the consequent reactions with oxygen. Their stability and reliability for outdoor applications are tested through weathering at various locations around the world. Until 2015, when systematic research into plastics started at the JGM, no information on the resistance of plastics to the Antarctic climate was available.
