Ocean acidification (OA) and microplastics (MPs) contamination are two results of human excises. In regions like estuarine areas, OA and MPs exposure are happening at the same time. The current research investigated the synthesized effects of OA and MPs exposure for a medium-term duration on the physiology and energy budget of the thick shell mussel Mytilus coruscus. Mussels were treated by six combinations of three MPs levels (0, 10 and 1000 items L⁻¹) × two pH levels (7.3, 8.1) for 21 d. As a result, under pH 7.3, clearance rate (CR), food absorption efficiency (AE), respiration rate (RR), and scope for growth (SFG) significantly decreased, while the fecal organic dry weight ratio (E) significantly increased. 1000 items L⁻¹ MPs led to decrease of CR, E, SFG and increase of AE under pH 8.1. Interactive effects from combination of pH and MPs were found in terms of CR, AE, E and RR, but not for SFG of M. coruscus.

海洋酸化 (OA) 和微塑料 (MPs) 污染是人类消费的两个结果。在河口地区等地区，OA 和 MPs 暴露同时发生。目前的研究调查了 OA 和 MPs 中期暴露对厚壳贻贝Mytilus coruscus的生理和能量收支的综合影响。贻贝通过三种 MPs 水平（0、10 和 1000 项 L ^-1）×两种 pH 水平（7.3、8.1）的六种组合处理 21 天。结果，在 pH 7.3 下，清除率 (CR)、食物吸收效率 (AE)、呼吸率 (RR) 和生长范围 (SFG) 显着降低，而粪便有机干重比 (E) 显着增加。1000 件 L ^-1在 pH 8.1 下，MP 导致 CR、E、SFG 降低和 AE 增加。在 CR、AE、E 和 RR 方面发现了 pH 和 MPs 组合的交互作用，但对M. coruscus的 SFG 没有发现。
