Analysis of MC 252 Control Oil by five different laboratories as a quality control sample for biomarkers, PAH, SHC, TPH, BTEX/PIANO

Macondo source oil (an aliquot of the oil collected during the Deepwater Horizon (DWH) oil release) was analyzed as a quality control (QC) sample by analytical laboratories along with the analyses of the field collected environmental samples. This QC sample analysis is generally referred to as “MC252 control oil.” MC252 control oil analyses were specified as an analytical requirement in the NRDA Analytical Quality Assurance Plan (NOAA 2011). This data set includes the chemistry data associated with available MC252 control oil analyses that support the chemistry data posting available on this website. In all, five different labs analyzed a laboratory control oil derived from the same parent source. There are 5007 different analyses of the control oil children. The control oil samples were analyzed for biomarkers, BTEX/PIANO, PAH/aPAH, Other PAH, SHC, TPH, and solids.马孔多源原油（Macondo source oil，即深水地平线（Deepwater Horizon, DWH）漏油事件中采集的原油等分试样）由分析实验室作为质量控制（QC）样本，与现场采集的环境样品一同开展分析。该质控样本的分析通常被称为“MC252对照油”。MC252对照油的分析要求是《NRDA分析质量保证计划》（NRDA Analytical Quality Assurance Plan，NOAA 2011）中明确规定的分析任务。本数据集包含与现有MC252对照油分析相关的化学数据，这些数据支撑本网站已发布的化学数据内容。总计有5家不同的实验室对源自同一母源的实验室对照原油开展了分析，共获得5007组对照原油样本的分析结果。本次分析针对对照原油样本的生物标志物、BTEX/PIANO、多环芳烃（PAH）/烷基化多环芳烃（aPAH）、其他多环芳烃、SHC、总石油烃（TPH）以及固体组分展开。
