The issue of plastic pollution has dramatically intensified in the recent years. Our study investigates extensive plastic contamination of a sandy beach on a small Adriatic island. The beach was sampled on three occasions, in 2013, 2020 and 2022, using 1 m quadrats placed along the lower and upper strandlines, resulting in average litter concentrations of 385 ± 106, 1095 ± 522 and 129 ± 37 item m, respectively. The lower size limit of collected litter was 1 mm, thus including large microplastics. Plastic fragments (49-74 %) and plastic pellets (15 %-37 %) were predominant litter categories. The proportion of fragments is significantly higher during the tourist season with a more intensive cleaning regime (April-October), as opposed to the off-season (November-March). Fisheries and aquaculture litter was identified as a relevant source of pollution. More research is needed in the future into the microplastics smaller than 1 mm.
近年来，塑料污染问题急剧加剧。我们的研究调查了亚得里亚海一个小岛上一片沙滩的广泛塑料污染情况。该海滩于2013年、2020年和2022年分三次进行采样，沿着低潮线和高潮线放置1米见方的样方，平均垃圾浓度分别为每平方米385±106件、1095±522件和129±37件。收集到的垃圾最小尺寸限制为1毫米，因此包括大型微塑料。塑料碎片（49%-74%）和塑料颗粒（15%-37%）是主要的垃圾类别。与淡季（11月至次年3月）相比，在清洁力度更大的旅游季节（4月至10月），碎片的比例明显更高。渔业和水产养殖垃圾被确定为一个相关的污染源。未来需要对小于1毫米的微塑料进行更多研究。
