“…The interactive effects between pesticides commonly used in aquaculture and variations in environmental temperature not only have negative impacts on the physiology and survival of non-target aquatic invertebrate species [ 11 , 15 , 16 ], but they also have impacts on the biochemical parameters at the cellular level [ 24 , 42 , 43 , 44 , 45 ]. In the present study, the interaction between environmental temperature and the pesticide azamethiphos caused a significant increase in the levels of lipid peroxidation and protein carbonyls in O. chilensis .…”

Azamethiphos is used in the salmon industry to treat sea lice and is subsequently discharged into the sea, which may affect non-target species (NTS). A rise in seawater temperature could enhance the sensitivity of NTS. Thus, in the present investigation, the combined effects of azamethiphos (0 µg L−1, 15 µg L−1 and 100 µg L−1) and temperature (12 °C and 15 °C) was assessed over time (7 days) in the gonads and gills of the oyster Ostrea chilensis, assessing its oxidative damage (lipid peroxidation and protein carbonyls) and total antioxidant capacity. Our results indicated that in gonads and gills, lipid peroxidation levels increased over time during exposure to both pesticide concentrations. Protein carbonyl levels in gills increased significantly in all experimental treatments; however, in gonads, only pesticide concentration and exposure time effected a significant increase in protein damage. In both, gill and gonad temperature did not influence oxidative damage levels. Total antioxidant capacity in gonads was influenced only by temperature treatment, whereas in the gills, neither temperature nor azamethiphos concentration influenced defensive responses. In conclusion, our results indicated the time of pesticide exposure (both concentrations) had a greater influence than temperature on the cellular damage in this oyster.

“…From an ecotoxicological perspective, it is particularly interesting to investigate how temperature changes projected due to climate change will influence species’ sensitivity to pesticides or other chemicals in the environment. Indeed, there have recently been a variety of studies looking at those interactions, which found evidence for an increase in toxicity by increasing temperature conditions. − This highlights the need to address future climate scenarios in environmental risk assessment (ERA) for chemicals …”

Temperature is a crucial environmental factor affecting the distribution and performance of ectothermic organisms. This study introduces a new temperature damage model to interpret their thermal stress. Inspired by the ecotoxicological damage model in the General Unified Threshold model for Survival (GUTS) framework, the temperature damage model assumes that damage depends on the balance between temperature-dependent accumulation and constant repair. Mortality due to temperature stress is driven by the damage level exceeding a threshold. Model calibration showed a good agreement with the measured survival of Gammarus pulex exposed to different constant temperatures. Further, model simulations, including constant temperatures, daily temperature fluctuations, and heatwaves, demonstrated the model’s ability to predict temperature effects for various environmental scenarios. With this, the present study contributes to the mechanistic understanding of temperature as a single stressor while facilitating the incorporation of temperature as an additional stressor alongside chemicals in mechanistic multistressor effect models.
