Community Air Sampling and Monitoring Data

Data were collected to evaluate ambient air quality in coastal communities along the Gulf of Mexico shoreline, and around the perimeter of waste sites and decontamination sites and in other areas where petroleum odors were noted and/or reported by federal, state, and local agencies or the public. The data in this publication includes the results of ambient air samples and “real-time” air measurements collected by BP and its contractors to evaluate public exposure to airborne chemicals during the Response to the DWH accident. During the Response, two separate sampling and monitoring programs were implemented to evaluate ambient air quality along the Gulf of Mexico shoreline: the Community Air Sampling and Monitoring program and the Branch Area Perimeter Sampling and Monitoring program. The Community Air Sampling and Monitoring program included the collection of ambient air samples on a daily basis at fixed locations (i.e., stations) along the shoreline. Air samples were also collected near sites in Florida, Alabama, and Mississippi that were used to store wastes generated during the Response and near sites that were used to decontaminate vessels, equipment, and materials used to recover oil or where odors were noted or reported. Real-time air monitoring was conducted by teams in roaming vehicles that traversed the shoreline and communities along the Gulf Coast on a 24 hour per day, 7 days per week basis. Air monitoring was conducted every 5 miles between Apalachee Bay, Florida and Port Arthur, Texas, and at other locations in response to potential concerns identified by the Unified Area Command or the public. The community air data sets include: (1) the chemistry results of approximately 6,100 ambient air samples collected at approximately 40 unique sampling stations and (2) the results of over 470,000 real-time measurements of ambient chemical concentrations collected at over 141,000 discrete stations. In the Branch Area Perimeter Sampling and Monitoring Program sampling teams in Louisiana collected ambient air samples and conducted air monitoring at the perimeter of properties (known as branches) that were used for waste storage and/or vessel or boom decontamination activities. The perimeter air data sets include the chemistry results of approximately 3,900 ambient air samples collected at approximately 38 unique sampling stations and the results of over 277,000 real-time measurements collected at over 69,000 discrete stations. Community and work area perimeter air samples were collected and analyzed for the following chemical parameters: • VOCs and tentatively identified compounds (TICs). • SVOCs. • Hydrogen Sulfide (H2S). In addition to the air samples collected for laboratory analysis; the sampling vehicles conducted air monitoring along designated community, or perimeter routes using calibrated air monitoring equipment. Measurements included: • Total VOCs • Benzene • H2S • sulfur dioxide (SO2) • Particulate matter less than 2.5 micrometer diameter (PM2.5) • Carbon Monoxide (CO)本数据集采集数据旨在评估墨西哥湾沿岸沿海社区、废物处置场及净化场地周边，以及联邦、州、地方机构或公众发现并报告存在石油类异味的其他区域的环境空气质量。本出版物收录的数据，源自英国石油公司（BP）及其承包商在响应深水地平线（DWH）事故期间，为评估公众暴露于空气中化学物质的情况所采集的环境空气样本结果与“实时”空气监测数据。 响应行动期间，共实施两套独立的采样与监测方案，以评估墨西哥湾沿岸的环境空气质量：分别为社区空气采样与监测计划，以及分支区域周边采样与监测计划。 社区空气采样与监测计划在沿岸固定点位（即监测站）每日开展环境空气样本采集。此外，还在佛罗里达州、阿拉巴马州及密西西比州用于储存响应行动产生废物的场地周边，以及用于净化回收油污所用船舶、设备与材料的场地周边，或存在异味报告的场地周边采集空气样本。监测团队乘坐移动车辆开展实时空气监测，每日24小时、每周7天遍历墨西哥湾沿岸及沿线社区。监测范围覆盖从佛罗里达州阿巴拉契湾到得克萨斯州亚瑟港之间每5英里的区域，以及联合区域指挥部或公众提出潜在担忧的其他点位。 社区空气数据集包含两项内容：(1) 约40个独特采样站采集的约6100份环境空气样本的化学分析结果；(2) 逾14.1万个离散点位采集的超47万条实时空气化学浓度监测数据。 在分支区域周边采样与监测计划中，路易斯安那州的采样团队在用于废物储存、船舶或围油栏净化作业的场地（即“分支场地”）周边采集环境空气样本并开展空气监测。周边空气数据集包含约38个独特采样站采集的约3900份环境空气样本的化学分析结果，以及逾6.9万个离散点位采集的超27.7万条实时监测数据。 社区及作业区域周边的空气样本采集后，针对以下化学参数开展分析： • 挥发性有机物（VOCs）及暂定识别化合物（TICs） • 半挥发性有机物（SVOCs） • 硫化氢（H₂S） 除用于实验室分析的空气样本外，采样车辆还使用校准后的空气监测设备，沿指定社区或周边路线开展空气监测。监测参数包括： • 总挥发性有机物（Total VOCs） • 苯（Benzene） • 硫化氢（H₂S） • 二氧化硫（SO₂） • 直径小于2.5微米的颗粒物（PM2.5） • 一氧化碳（CO）
