摘要： Microplastics (MPs) contamination and salinity fluctuation are two common phenomena on the East China Sea coast. The purpose of this experiment was to evaluate the combined effects of MPs and salinity on the energy budget of the thick shell mussel Mytilus coruscus. Juvenile mussels were exposed to six combined treatments with three MPs levels (0, 10 and 1000 items L-1) and two salinity levels (15, 25) for 28 d. The clearance rate, food absorption efficiency, respiration rate, ammonium excretion rate, and O:N ratio were significantly reduced, and the fecal organic dry weight ratio was significantly increased at salinity 15, inducing a reduction in the scope for growth. Under salinity 15, 1000 items L-1 MPs had significant negative effects on growth at Day 28. However, under salinity 25, the results were opposite in that the level of 1000 items L-1 MPs brought an obvious increment in scope for growth at Day 28. This meant that there were interactions between salinity and MPs in scope for growth at Day 28. These results suggest that the physiological energetics of juvenile M. coruscus can acclimate to MPs contamination with little physiological effect under normal salinity. This experiment has revealed that although marine MPs contamination is of concern, marine organisms likely have a significant capacity to adapt to it.
