本研究对亚得里亚海中部浮游和海床宏微凋落物的丰度、分布和组成进行了研究。对漂浮的大型凋落物进行了观测。分别用螳螂网和Van Veen Grab对浮游和海底微凋落物进行采样。用傅里叶变换红外显微镜对显微镜下观察到的微小垃圾颗粒进行了化学分析。浮游宏观(175 物件/平方公里)、漂浮微观(127 千 颗粒物/平方公里)和海底微凋落物(36 颗粒物/100 g干重)的平均计算浓度与地中海发表的其他研究结果相似。位于航道水域的浮游微量和宏观凋落物浓度之间存在显著的统计学相关性(p<； )。模型和观测之间的不一致揭示了我们对海洋环流和垃圾来源的认识上的差距。在不同的海洋舱室对海洋垃圾进行同步采样和观察证明是可能的、有效的和提供信息的。
In this study, abundance, distribution and composition of floating and seabed macro and micro litter in the Central Adriatic Sea were assessed. Floating macro litter observations were made. Floating and seabed micro litter were sampled with manta net and Van Veen grab, respectively. Micro litter particles visually found under the microscope were chemically analyzed with Fourier Transform Infrared microscope. Average calculated concentrations of floating macro (175 items/km2), floating micro (127 thousand particles/km2) and seabed micro litter (36 particles/100 g dry weight) show similar values as other published studies from the Mediterranean Sea. A statistically significant (p< 0.01) correlation between the floating micro and macro litter concentrations was found for the sites located in the channel waters. Disagreement between model and observations revealed gaps in our knowledge concerning the sea circulation and litter sources. Simultaneous samplings and observations of marine litter in different marine compartments proved possible, efficient and informative.
