Concentration of organic compounds in aerosols and surface waters of the East Atlantic and Antarctic

The data on content and composition of lipids and aliphatic hydrocarbons (HC) in aerosols and surface waters obtained during the spring-summer periods of 2001 and 2003 along the vessel route from the North Sea to the Antarctic and backwards are presented. It was shown that the distribution of organic compounds is caused by influence of zonal supply of eolian matter from land, anthropogenic, and marine autochtonous sources. Concentrations of organic compounds in the aerosols varied from 0.22 to 13.04 ng/m**3 for lipids and from 0.04 to 7.03 ng/m**3 for aliphatic HC; in surface waters, it from 9 to 84 and from 1 to 53 µg/l, respectively. There is correlation between fluxes of lithogenic fraction of the aerosols, HC, and lipids. Growth of productivity in the aquatic area increases levels of the HC in the surface waters but to a lower degree than HC supply with oil contamination.

本数据集呈现了2001年与2003年春夏两季，沿船舶航线从北海至南极并返程采集的气溶胶（aerosol）与地表水（surface water）中脂质（lipids）及脂肪烃（aliphatic hydrocarbons，HC）的含量与组成数据。研究表明，有机化合物的分布格局受陆地风成物质、人为源及海洋内源的区域输入影响。气溶胶中有机化合物的浓度范围为：脂质0.22~13.04 ng/m³，脂肪烃（HC）0.04~7.03 ng/m³；地表水中相应浓度范围分别为9~84 μg/L与1~53 μg/L。气溶胶岩源性组分（lithogenic fraction）的通量与脂肪烃（HC）、脂质之间存在相关性。水体区域的生产力提升会提高地表水中脂肪烃（HC）的含量，但其提升幅度低于石油污染输入所带来的脂肪烃含量增幅。
