大量不同的采样方法被用来记录海水中存在的微塑料碎片。欧洲海洋战略建议改进标准技术，使未来的数据具有可比性。我们使用曼塔拖网采样技术，以量化的丰度和分布的微塑料碎片在撒丁海（西地中海），以及它们与邻苯二甲酸酯和有机氯在neustonic栖息地的关系。我们的研究结果突出了相当高的平均塑料丰度值（0.15个/m3），与地中海其他地区检测到的水平相当。“场地”是唯一能显著解释微塑料密度差异的因素。污染物水平在空间和时间上有很大的变化。在每个监测站，六氯苯是浓度最低的污染物，而多氯联苯的浓度最高。这项工作符合海洋战略指令，是分析塑料对撒丁岛海洋环境影响的初步研究。(c)2014爱思唯尔有限公司版权所有。
A plethora of different sampling methodologies has been used to document the presence of micro-plastic fragments in sea water. European Marine Strategy suggests to improve standard techniques to make future data comparable. We use Manta Trawl sampling technique to quantify abundance and distribution of micro-plastic fragments in Sardinian Sea (Western Mediterranean), and their relation with phthalates and organoclorine in the neustonic habitat. Our results highlight a quite high average plastic abundance value (0.15 items/m(3)), comparable to the levels detected in other areas of the Mediterranean. "Site" is the only factor that significantly explains the differences observed in micro-plastic densities. Contaminant levels show high spatial and temporal variation. In every station, HCB is the contaminant with the lowest concentration while PCBs shows the highest levels. This work, in line with Marine Strategy directives, represents a preliminary study for the analysis of plastic impact on marine environment of Sardinia. (c) 2014 Elsevier Ltd. All rights reserved.
