This is the first survey to investigate the occurrence and extent of microplastic contamination in sediments collected along a coast-open sea 140km-long transect in the Central Adriatic Sea. Plastic debris extracted from 64 samples of sediments were counted, weighted and identified by Fourier-transform infrared spectroscopy (FT-IR). Several types of plastic particles were observed in 100% of the stations. Plastic particles ranged from 1 to 30mm in length. The primary shape types by number were filaments (69.3%), followed by fragments (16.4%), and film (14.3%). Microplastics (1-5mm) accounted for 65.1% of debris, mesoplastics (5-20mm) made up 30.3% of total amount, while macro debris (>20mm) accounted for 4.6% of total plastics collected. Identification through FT-IR spectroscopy evidenced the presence of 6 polymer types: the majority of plastic debris were nylon, polyethylene and ethylene vinyl alcohol copolymer. Our data are a baseline for microplastic research in the Adriatic Sea.
这是首次调查研究在亚得里亚海中部 140 公里长的海岸-外海沿岸沉积物中微塑料污染的发生和程度。从 64 个沉积物样本中提取的塑料碎片通过傅里叶变换红外光谱(FT-IR)进行计数、称重和鉴定。在 100%的站位都观察到了几种类型的塑料颗粒。塑料颗粒的长度范围为 1 至 30 毫米。按数量计,主要形状类型是纤维(69.3%),其次是碎片(16.4%)和薄膜(14.3%)。微塑料(1-5 毫米)占碎片的 65.1%,中塑料(5-20 毫米)占总量的 30.3%,而大碎片(>20 毫米)占收集到的塑料总量的 4.6%。通过 FT-IR 光谱鉴定证明存在 6 种聚合物类型:大多数塑料碎片是尼龙、聚乙烯和乙烯-乙烯醇共聚物。我们的数据为亚得里亚海的微塑料研究提供了基线。
