Abstract
This paper aims at assessment of microplastics concentrations on the beaches of the Sea of Azov and research of morphological features, size of particles, level and ways of degradation (or destruction) of microplastics. During the study, 126 samples of beach deposits were taken at 14 points of the beaches of the Sea of Azov and Kerch Strait. The samples were processed using the modified method NOAA. The analysis showed pollutant’s presence in 100 % of the samples. The concentration of microplastics particles in sand samples from different areas of the beach varies from 12 to 112 pieces per 1 m2 . The highest concentration was found on the beaches in Taganrog and the village of Ilyich. Morphological features of the particles were studied using a stereo microscope (Micromed MC-1 2C Digital). Translucent fibres and membranes prevailed in all the samples. Study of size frequency showed that the most frequently observed are particles of 0.2 mm, the median of size range being 0.5 mm. Types of microplastics degradation were determined using a scanning electron microscope (VEGA II LMU). Dissection, fracturing, and splitting were recorded
本文旨在评估亚速海海滩上的微塑料浓度,并研究微塑料的形态特征、颗粒大小、水平和降解(或破坏)方式。在研究期间,在亚速海和刻赤海峡的14个海滩点采集了126个海滩沉积物样本。采用改进的NOAA法对样品进行处理。分析表明,100%的样本中都含有污染物。来自海滩不同区域的沙子样本中的微塑料颗粒浓度从每1平方米12到112个不等。在Taganrog和Ilyich村的海滩上发现的浓度最高。用立体显微镜(Micromed mc - 12c Digital)研究了颗粒的形态特征。半透明纤维和膜在所有样品中普遍存在。粒径频率的研究表明,最常观察到的是0.2 mm的颗粒,粒径范围的中位数为0.5 mm。使用扫描电子显微镜(VEGA II LMU)确定微塑料降解类型。记录解剖、骨折和劈裂
