中国第7次北极科学考察（2016）表层海水重金属分析数据

重金属是海水中一类非常重要的污染物质，通过调查重金属浓度，可以理解区域海水中的重金属污染程度。
本数据为中国第7次北极科学考察北极雪龙船航迹表层海水中重金属调查数据，对了解调查区域内海水中重金属污染程度具有重要科学意义。采用《极地生态环境监测规范》(试行)作为样品采集以及分析方法依据，重金属采用ICP-MS进行分析，海水中汞采用原子荧光光度计测定。所有仪器设备均经过计量检定且在有效期内，分析空白、平行样、质控样测试均符合有关规范要求。

Heavy metals are a critically important class of marine pollutants. Investigating their concentrations in seawater enables assessment of the degree of heavy metal contamination in regional marine environments.
This dataset contains heavy metal survey data collected from surface seawater along the navigation track of the Chinese icebreaker Xuelong during the 7th Chinese Arctic Scientific Expedition, which holds significant scientific value for understanding the extent of heavy metal contamination in the surveyed area.
Technical Specifications for Polar Ecological Environment Monitoring (Trial Implementation) was adopted as the basis for sample collection and analytical procedures. Heavy metals were analyzed via inductively coupled plasma mass spectrometry (ICP-MS), while mercury in seawater was determined using atomic fluorescence spectrometry. All instruments and equipment had undergone metrological verification and were within their valid calibration periods. Tests for analytical blanks, parallel samples, and quality control samples all complied with relevant specification requirements.
