Dispersion of Louisiana crude oil in salt water environment by Corexit 9500A in the presence of natural coastal materials.

Data supporting the publication DOI: 10.1016/j.ecss.2014.03.022 http://www.sciencedirect.com/science/article/pii/S0272771414000705 Effectiveness of Corexit 9500A for dispersing Louisiana crude oil was evaluated in salt water solutions containing natural materials in relation to salinity and dispersant-to-oil ratio (DOR). Experimental results showed that both salinity and DOR had significant effects on dispersion of Louisiana crude oil in the presence of different natural materials. The natural materials added to the salt water solutions included sea sand (South Beach, Miami, Florida), red mangrove leaves (Rhizophora mangle), seaweed (Sargassum natans), and sea grass (Halodule wrightii). Dispersant effectiveness (amount of oil dispersed into the water) was reduced significantly with increasing salinity with the minimum effectiveness observed in the salinity range between 30 and 50 ppt in all aqueous samples containing natural materials.支撑该学术论文的配套数据，论文DOI为：10.1016/j.ecss.2014.03.022，原文链接：http://www.sciencedirect.com/science/article/pii/S0272771414000705。本研究针对Corexit 9500A对路易斯安那原油的分散效能，在含有天然物质的盐水溶液体系中，结合盐度与分散剂-油比（dispersant-to-oil ratio，DOR）两个变量开展了评估。实验结果表明，在不同天然物质存在的条件下，盐度与DOR均对路易斯安那原油的分散效果产生显著影响。本次实验添加至盐水溶液的天然物质包括：佛罗里达州迈阿密南海滩海砂、美洲红树（Rhizophora mangle）叶片、漂浮马尾藻（Sargassum natans）以及泰来草（Halodule wrightii）。分散剂效能（即分散至水体中的原油总量）随盐度升高呈显著下降趋势；在所有含有天然物质的水溶液样品中，当盐度处于30~50 ppt区间时，分散剂效能达到最低值。
