英文摘要	Hypoxia, largely triggered by anthropogenic activities and global climate change, exerts widespread and expanding stress on marine ecosystems. As an emerging contaminant, the influence of nanoplastics on marine organisms has also attracted attention in recent years. However, the impact of hypoxia on the risk assessments of nanoplastics is rarely considered. This study investigated the toxicity of PS-NPs (0, 0.5, and 5 mg/L) to the coastal mussels Mytilus galloprovincialis under different patterns of hypoxia (normoxia, constant hypoxia, and fluctuating hypoxia). The results showed that constant hypoxia might reduce the accumulation of PS-NPs in mussels by decreasing the standard metabolic rate. The impairment of PS-NPs on mussel immunity was also exacerbated by constant hypoxia. Fluctuating hypoxia did not affect the accumulation of PS-NPs, but aggravated the oxidative damage caused by PS-NPs. These findings emphasize the importance of environmental factors and their temporal variability in plastic risk assessment.(c) 2021 Elsevier B.V. All rights reserved.
