将墨西哥湾水样中TPH和PAH的泄漏前背景浓度与深水地平线事件期间和之后收集的样品（超过20，000个）（13，000个站点）进行比较。样本由多个响应机构、受托人和英国石油公司收集，并在海湾科学数据中报告。从井口几米到800多公里的各个方向采集样品。在事故发生期间，碳氢化合物浓度最高的样本是在井口附近采集的，或者是从表层浮油和分散剂使用中采集的样本。在报告的13，172份水样中，84%的水样中TPH浓度低于1微克/升（背景）。在报告的16，557份水样中，79%的PAH浓度低于0.056微克/升（中位数字段空白，背景）。在孔加盖后，低于背景的样品百分比迅速增加。这些碳氢化合物数据的空间和时间分布。(C)2016爱思唯尔有限公司版权所有
Pre-spill background concentrations of TPH and PAH in water samples from the Gulf of Mexico are compared with samples (over 20,000) collected during and after the Deepwater Horizon incident (13,000 stations). Samples were collected by multiple response agencies, trustees and BP and reported in the Gulf Science Data. The samples were collected from a few m to over 800 km in all directions from the wellhead. During the incident, samples with the highest concentrations of hydrocarbons were collected proximal to the wellhead or in samples collected from surface slicks and dispersant use. Of the 13,172 water sample TPH concentrations reported, 84% were below 1 mu g/L (background). Of the 16,557 water sample PAH concentrations reported, 79% were below 0.056 mu g/L (the median field blank, background). The percentage of samples below background increased rapidly after the well was capped. The spatial and temporal distributions of these hydrocarbon data are presented. (C) 2016 Elsevier Ltd.
