实验室“海洋生物-环境联动研究”团队朱静敏博士、王京真副教授关于鲸豚类微塑料威胁的研究论文“Cetaceans and microplastics: First report of microplastic ingestion by a coastal delphinid, Sousa chinensis” 在国际顶端（TOP）SCI期刊Science of the Total Environment, 2019, 695: 649-654（IF = 5.589）上发表。

研究首次揭示了近岸海豚科潜在的微塑料威胁；首次建立了鲸豚类非肠道全长的微塑料检测方法；首次在幼年海豚科个体肠道检测到微塑料。中华白海豚成年个体和幼年个体肠道内均可检测到微塑料，说明捕食和误食都可能是鲸豚类塑料积累的途径。中华白海豚肠道微塑料在形状、颜色、大小和材质的主要属性分别为纤维状、白色和蓝色、1-5 mm、聚酯，与微塑料的环境背景存在潜在关系。中华白海豚的前肠比中肠和后肠更易检测到微塑料，可能与鲸豚类的肠道结构有关。鲸豚类作为环境的指示物种和旗舰物种对环境和生态保护意义重大，本研究的相关发现为鲸豚类保育、为近岸海洋环境的保护和管理提供了重要信息。

文章摘要：

In the Anthropocene, marine microplastic debris has been rapidly increasing and interacting with wildlife. As apex predators, cetaceans have been proven to be ideal sentinel species to indicate ecosystem changes and umbrella and flagship species to help develop environmental management strategies. Here, we report the presence of microplastics in the intestines of Sousa chinensis for the first time, which highlights the potential impacts of microplastic pollution in coastal environments. Microplastics were detected in the intestinal contents of both adult and calf individuals, indicating that consumption of prey and unintentional ingestion are the potential pathways for microplastic accumulation in Sousa chinensis. The properties of the microplastics indicated that fibers, white and blue items, 1–5 mm items, and polyester were the predominant shapes, colors, sizes and plastic materials, respectively. More microplastics were detected in the foreguts and midguts than in the hindguts, which may be correlated with the specific intestinal structure of Sousa. This study indicates that coastal delphinids might suffer from microplastic pollution, even young calves. The sample size in this study is limited, whereas it's a starting point for assessing microplastics in the endangered coastal delphinid, Sousa. We suggest that assessments of the risks of microplastic consumption by cetaceans and the presence of microplastics in their habitats should be conducted at a global scale. Moreover, further works should be done to look for evidence of adverse effects of microplastics pollution on cetaceans.
