Asian seabass, Lates calcarifer frys were exposed to polystyrene (MP: 0.5 mg/l), oil (0.83 ml/l) and agglomerates (MP + oil + Corexit) as eight treatments in three replicates, and fresh synthetic marine water (control) for 15 days. The synergistic effect was confirmed (P ˂ 0.05) by bio-indicators including RBC count, total plasma protein, aspartate aminotransferase (AST), catalase (CAT), glutathione S-transferase (GST), basophils, thrombocyte and eosinophils percentages. Most of the significant and synergistic effects were observed in the highest doses (5 mg/l MP and 5 mg/l MP-oil-dispersant). Exposure to MP and a combination of MP+ oil caused tissue lesions in gill, liver and intestine. Our results suggest there are no critical health issues for Asian seabass in natural environments. However, the bioaccumulation of MPs, oil, and their agglomerates in consumers' bodies may remain a concern.
尖吻鲈（Lates calcarifer）鱼苗被暴露于聚苯乙烯微塑料（MP：0.5毫克/升）、油（0.83毫升/升）和团聚物（MP+油+Corexit）中，设置8种处理方式，每种处理重复3次，并设置新鲜合成海水作为对照（空白组），实验持续15天。通过包括红细胞计数、总血浆蛋白、天冬氨酸转氨酶（AST）、过氧化氢酶（CAT）、谷胱甘肽S-转移酶（GST）、嗜碱性粒细胞、血小板和嗜酸性粒细胞百分比等生物指标，证实了协同效应（P＜0.05）。大多数显著和协同效应在最高剂量组（5毫克/升MP和5毫克/升MP-油分散剂）中观察到。暴露于MP以及MP与油的组合会导致鳃、肝脏和肠道的组织损伤。我们的研究结果表明，在自然环境中，尖吻鲈不存在严重的健康问题。然而，微塑料、油及其团聚物在消费者体内的生物累积可能仍然是一个令人担忧的问题。
