Emissions from building materials - concentration of micropollutants and heavy metals in stormwater runoff of two new development areas in Berlin (Germany)

This dataset includes concentrations of micropollutants (27) and heavy metals (7) for stormwater runoff from different sampling points at two test sites (A and B) in Berlin, Germany. Both sites are new development areas of similar size that were both constructed in 2017 (1 – 1.5 years prior to the start of the monitoring campaign). Composite samples of individual rain events were taken at three sampling points of each test site: façade runoff, roof runoff and corresponding stormwater runoff from the catchment area. Samples were taken as part of the research project BaSaR (www.kompetenz-wasser.de/en/forschung/projekte/basar/) of Kompetenzzentrum Wasser Berlin, Ostschweizer Fachhochschule and Berliner Wasserbetriebe. More information including sampling and analytical methods are detailed in the corresponding journal paper "Emissions from building materials – a thread for the environment?", submitted to the MDPI-journal <em>Water</em>. <strong>Description of fields:</strong> <strong>SiteID</strong>: site identifier A: new development site with typical architecture for multi-storey apartment buildings with plastered and painted facades in northern part of Berlin (124 apartments) B: new development site with typical architecture for multi-storey apartment buildings with plastered and painted facades in southeastern part of Berlin (122 appartments) <strong>SamplingPoint</strong> facade runoff: runoff from plastered facade collected with gutters during individual rain events roof runoff: roof runoff collected from one downpipe during individual rain events storm sewer: stormwater runoff sampled during individual rain events in a manhole receiving runoff from the entire catchment (A or B) <strong>LocalDateTime_StartRain</strong>: start time of sampled rain event (CET / CEST) <strong>LocalDateTime_EndRain</strong>: end time of sampled rain event (CET / CEST) <strong>CardinalDirection</strong>: only relevant for facade runoff N: runoff from facade oriented to the north W: runoff from facade oriented to the west <strong>VariableName</strong>: name of analysed substance/parameter <strong>CensorCode</strong>: either "lt" (less than) for concentration below detection limit (value is detection limit) or "nc" (not censored) for concentration above detection limit <strong>UnitsAbbreviation</strong>: either "ug/L" (microgram per litre) or "mg/L" (milligram per litre) <strong>DataValue</strong>: measured value (if censor code is lt, value indicates detection limit) One data file is provided in comma separated format:<br> "BaSaR_data.csv" contains concentrations of all samples.本数据集涵盖德国柏林两处2017年建成的相似规模新建开发区（点位A与B）的雨水径流中微污染物（micropollutants，共27种）与重金属（heavy metals，共7种）的浓度数据。监测活动启动时，两处开发区已建成1至1.5年。 两处测试点位各设置3个采样点，采集每场降雨事件的混合径流样品：立面径流、屋面径流以及对应汇水区的雨水总径流。 本数据采集工作隶属于由柏林水能力中心（Kompetenzzentrum Wasser Berlin）、东瑞士应用科技大学（Ostschweizer Fachhochschule）与柏林水务公司（Berliner Wasserbetriebe）联合开展的BaSaR研究项目（项目网址：www.kompetenz-wasser.de/en/forschung/projekte/basar/）。更多采样与分析方法细节可参阅提交至MDPI期刊《Water》的学术论文《建筑材料排放——环境隐患？》（Emissions from building materials – a thread for the environment?）。 **字段说明：** **点位标识（SiteID）**： - A：柏林北部新建多层公寓楼开发区，建筑外立面均经抹灰与涂装，共设124套公寓 - B：柏林东南部新建多层公寓楼开发区，建筑外立面均经抹灰与涂装，共设122套公寓 **采样点位（SamplingPoint）**： - 立面径流（facade runoff）：每场降雨事件中通过天沟收集的抹灰外立面径流 - 屋面径流（roof runoff）：每场降雨事件中从单根落水管采集的屋面径流 - 雨水管网（storm sewer）：每场降雨事件中在接纳全汇水区（A或B）径流的检查井内采集的雨水径流 **降雨开始本地时间（LocalDateTime_StartRain）**：采样降雨事件的起始时间，采用中欧时间（CET）/中欧夏令时（CEST） **降雨结束本地时间（LocalDateTime_EndRain）**：采样降雨事件的结束时间，采用中欧时间（CET）/中欧夏令时（CEST） **方位朝向（CardinalDirection）**：仅立面径流相关数据有效 - N：北向外立面径流 - W：西向外立面径流 **分析物质/参数名称（VariableName）**：已检测的物质或参数名称 **截尾编码（CensorCode）**：若取值为"lt"（小于），表示浓度低于检出限，此时检测值字段数值为检出限；若取值为"nc"（未截尾），表示浓度高于检出限 **浓度单位缩写（UnitsAbbreviation）**：可选值为"ug/L"（微克/升）或"mg/L"（毫克/升） **检测值（DataValue）**：实测浓度值；若截尾编码为"lt"，则该值为检出限数值 数据集以逗号分隔格式提供单个数据文件：`BaSaR_data.csv`，包含所有样品的浓度数据。
