铅和汞浓度和同位素数据是评估北极铅汞污染状况的重要基础指标。本研究利用web of science检索筛选获得高质量的北极不同环境介质中的铅和汞浓度和同位素组成的数据。其中，铅和汞浓度数据使用电感耦合等离子体质谱仪、原子荧光光谱仪、原子吸收光谱、测汞仪和中子活化法进行测定。所有的汞同位素使用多接收器电感耦合等离子体质谱仪测定，铅同位素使用（多接收器）电感耦合等离子体质谱仪和热电离质谱计测定。该数据集环境介质样品多，涵盖土壤，大气，生物等，时间跨度长，全面且详细，可为北极陆地生态系统铅和汞循环的系统研究提供基础数据支持。", "ds_source": "
Web of science收录了1900年以来经过同行评议的文章，这些文献的正文表格和附件中往往提供了有关铅和汞浓度和同位素的数据。通过摘要阅读，数据质量评估，附件或正文下载和联系作者，我们筛选，整理和汇总了目前已发表的高质量的铅和汞浓度和同位素组成的数据集合。", "ds_process_way": "

每篇文献在报道数据的同时都进行了质量控制，例如铅汞浓度测试均同时测试了标样和重复样，具有较好的回收率和重复性。铅和汞同位素数据测试的同时测试了标样的同位素组成，标样的值在可接受范围内。报道的数据集是高质量，有可信度的。", "ds_acq_start_time": "1968-01-01 00:00:00", "ds_acq_end_time": "2025-12-31 00:00:00", "ds_acq_place": "北极", "ds_acq_lon_east": 180.0, "ds_acq_lat_south": 60.0, "ds_acq_lon_west": -180.0, "ds_acq_lat_north": 90.0, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "login-access", "ds_total_size": 760899, "ds_files_count": 2, "ds_format": "*.xls", "ds_space_res": "", "ds_time_res": "", "ds_coordinate": "WGS84", "ds_projection": "Albers Equal Area Conic Projection System", "ds_thumbnail": "fdad861d-73b8-496b-945a-bcf081624fe9.png", "ds_thumb_from": 2, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "53943799-d453-4bf2-a141-56c205c1355b", "ds_serv_man": "李红星", "ds_serv_phone": "0931-4967592", "ds_serv_mail": "ncdc@lzb.ac.cn", "doi_value": "", "subject_codes": [ "170.3030" ], "quality_level": 3, "publish_time": "2026-05-07 11:33:44", "last_updated": "2026-05-07 16:14:11", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.NCDC.ARCTIC-CHANGE.DB7135.2026", "i18n": { "en": { "title": "Long-term lead and mercury concentrations and isotopes dataset for the Arctic environmental media samples from 1968 to 2025", "ds_format": "*.xls", "ds_source": "
Web of Science collects peer-reviewed articles since 1900, often providing data on lead and mercury concentrations and isotopes in the main body tables and attachments. By reading abstracts, assessing data quality, downloading attachments or main text, and contacting authors, we have screened, organized, and summarized a collection of high-quality published data on lead and mercury concentrations and isotopic compositions.", "ds_quality": "
Each literature conducted quality control while reporting data, for example, lead mercury concentration testing was conducted on both standard and duplicate samples, with good recovery and repeatability. During the testing of lead and mercury isotope data, the isotopic composition of the standard sample was also tested, and the values of the standard sample were within an acceptable range. The dataset reported is of high quality and credible.", "ds_ref_way": "", "ds_abstract": "
Lead and mercury concentrations and isotope data are important fundamental indicators for assessing the status of lead and mercury pollution in the Arctic. This study utilized Web of Science to retrieve and screen high-quality data on lead and mercury concentrations and isotopic compositions in different environmental media in the Arctic. Among them, lead and mercury concentration data were measured using inductively coupled plasma mass spectrometry, atomic fluorescence spectrometer, atomic absorption spectroscopy, mercury analyzer, and neutron activation method. All mercury isotopes were measured using a multi receiver inductively coupled plasma mass spectrometer, while lead isotopes were measured using a (multi receiver) inductively coupled plasma mass spectrometer and a thermal ionization mass spectrometer. This dataset contains a large number of environmental media samples, covering soil, atmosphere, biology, etc. It has a long time span, is comprehensive and detailed, and can provide basic data support for the systematic study of lead and mercury cycling in Arctic terrestrial ecosystems.", "ds_time_res": "", "ds_acq_place": "Arctic", "ds_space_res": "", "ds_projection": "", "ds_process_way": "
