中国第38次南极科学考察(2021-2022年)南大洋海水持久性有机污染物分析数据

2021-2022年中国第38次南极科学考察期间，通过南极半岛、普里兹湾、罗斯海海域水体及沉积物的油类、微塑料、持久性有机污染物调查，从多个角度认识南极半岛、普里兹湾、罗斯海的污染物分布情况，揭示极地污染物的分布特征、主要来源和迁移路径，评估南极区域污染物对环境的影响及生态效应，为我国在处理国际海洋污染物问题提供研究基础与技术支撑。
本数据为第38次南极科学考察(2021-2022年)海水持久性有机污染物分析数据，数据内容包括站位、经度、纬度、日期、水深、萘、苊、苊烯、荧蒽、芘、苯并（a）蒽、PAHs、六六六、PCBs等。
1.样品采集设备
（1）船载表层海水分配系统
（2）高通量固相萃取系统
2.观测方法和所获观测资料
持久性有机污染（PAHs、666、DDT、PCBs）样品采用气相色谱质谱联用仪分析测定。
3.观测区域
本航次考察海区为南极半岛、普里兹湾、罗斯海海域。

During the 38th Chinese National Antarctic Research Expedition (2021-2022), surveys of oil, microplastics, and persistent organic pollutants (POPs) in water bodies and sediments across the Antarctic Peninsula, Prydz Bay, and Ross Sea were conducted. This study aims to understand the pollutant distribution patterns in the three regions from multiple perspectives, reveal the distribution characteristics, main sources and migration pathways of polar pollutants, assess the environmental impacts and ecological effects of pollutants in the Antarctic region, and provide research foundations and technical support for China in addressing international marine pollution issues.

This dataset is the analysis data of persistent organic pollutants in seawater collected during the 38th Chinese National Antarctic Research Expedition (2021-2022). The dataset includes station location, longitude, latitude, date, water depth, naphthalene, acenaphthene, acenaphthylene, fluoranthene, pyrene, benzo(a)anthracene, PAHs, hexachlorocyclohexane (666), PCBs, etc.

1. Sample Collection Equipment
(1) Shipboard surface seawater distribution system
(2) High-throughput solid-phase extraction system

2. Observation Methods and Obtained Observation Data
Samples of persistent organic pollutants (PAHs, 666, DDT, PCBs) were analyzed and determined using gas chromatography-mass spectrometry (GC-MS).

3. Observation Area
The survey sea areas of this cruise include the Antarctic Peninsula, Prydz Bay, and Ross Sea.
