Microplastic pollution in marine environments has increased rapidly during the last decades. These microplastic particles are transported into the coral reef environment from terrestrial origin. Recent investigations suggest that microplastic ingestion can adversely affect marine invertebrates, especially in the coral reef ecosystem. The present attempt has been carried out to identify the coral growth band impregnated microplastics from polished coral slabs and acid leached insoluble residues through microscopic examination. The impregnated microplastics have been present in the following descending order: Nylon > Polyester > Polypropylene > Polyethylene. The irregular-shaped black and red microplastic particles have been dominantly observed. The annual growth band impregnated microplastics are most probably derived from tourist activities and chiefly controlled by oceanic currents and sediment re-suspension. The maximum distribution of microplastics has been observed in the coral annual growth bands of 1964 and 2005.

Clinical Trials Registration The present work is not a clinically related project. Hence clinical registration is not obtained/not required for publishing the results.

珊瑚的年生长带浸渍微塑料（Porites sp。）：第一份调查报告

在过去的几十年中，海洋环境中的微塑料污染迅速增加。这些微量的塑料颗粒从陆源运到珊瑚礁环境中。最近的研究表明，摄入微塑料可能会对海洋无脊椎动物产生不利影响，尤其是在珊瑚礁生态系统中。本发明已尝试通过显微镜检查从抛光的珊瑚板和酸浸出的不溶性残留物中鉴定出珊瑚生长带浸渍的微塑料。浸渍的微塑料按以下降序排列：尼龙>聚酯>聚丙烯>聚乙烯。主要观察到不规则形状的黑色和红色塑料微粒。年增长带浸渍的微塑料最有可能来自旅游活动，并且主要受洋流和沉积物再悬浮的控制。在1964年和2005年的珊瑚年生长带中观察到了最大的微塑性分布。

临床试验注册目前的工作不是临床相关项目。因此，未获得临床注册/不需要公开临床结果。
