| 摘 要： | 微塑料是指最大粒径小于5 mm的塑料微粒,近年来其污染问题受到广泛的关注。2017年6月,在环渤海潮间带9个站位采集了野生长牡蛎(Crassostrea gigas)样品,通过组织消解、滤膜分离和显微镜检筛分微塑料样品,并利用显微傅里叶变换红外光谱仪(μ-FT-IR)对其化学成分进行分析。结果表明,环渤海潮间带长牡蛎体内的微塑料摄入率为73.91%～95.65%;微塑料平均丰度为2.03个/个体,每克生物组织平均丰度为0.89个。长牡蛎体内的微塑料形状以纤维类最多,所占比例为67.06%,其次为碎片类,薄膜和颗粒类所占比例较少。微塑料颜色以蓝色居多,其次为白色。长牡蛎体内粒径小于500μm的微塑料所占比例最高,其次为粒径500～1 000μm的微塑料。微塑料化学成分包括人造纤维、聚乙烯、聚对苯二甲酸乙二醇酯、聚丙烯、聚酰胺、聚苯乙烯等6种类型,其中人造纤维所占比例高达50.00%。以上结果表明,环渤海潮间带长牡蛎体内均存在一定的微塑料富集;与国内外其它研究相比,整体处于中等偏下水平;港口等站位的长牡蛎体内的微塑料丰度较高,而自然保护区站位的长牡蛎体内的微塑料丰度较低,表明微塑料污染与人类活动频繁程度密切相关。
