| Study Title | 1H NMR metabolomics applied to assess the metabolic response of Ruditapes philippinarum clams to sea warming and 17-α-ethinylestradiol exposure |
| Study Type | 1H NMR metabolomics to study the effects of warming conditions and exposure to 17-α-ethinylestradiol (EE2) on the polar metabolome of Ruditapes philippinarum clams |
| Study Summary | In this study, a comprehensive untargeted 1H NMR metabolomics strategy was applied to measure the metabolic impact of sea warming, in tandem with exposure to EE2, on Ruditapes philippinarum clams. The clams were exposed to five different EE2 concentrations: 0 (control group), 5, 25, 125 and 625 ng/L; either at 17 °C as control temperature or at 21 °C (representing a 4 °C increase, which corresponds to the worst-case warming scenario). The obtained data added important knowledge, unveiling individual metabolic effects of temperature rise and synergetic effects upon EE2 exposure, and paving the way for the definition of new metabolic markers for the monitoring of environmental stressors. |

Treatment:
| Treatment ID: | TR002557 |
| Treatment Summary: | Sea warming and 17-α-ethinylestradiol exposure. After depuration, the organisms were subjected to a chronic toxicity test for 28 days, consisting of exposure to five different EE2 concentrations: 0 (control group), 5, 25, 125 and 625 ng/L. To assess the effects of a warming scenario on the impacts of EE2, the experiments were carried out at 17 ± 1 °C (control; mean temperature of sampling area during September) and at 21 ± 1 °C (worst-case climate change scenario). The aquaria were placed in distinct climatic rooms for each temperature. To reach 21 °C, the temperature was raised by 2 °C, every 2–3 days. For each concentration level and temperature, 12 samples were considered: 4 individuals per aquarium and 3 aquaria per treatment. In each aquarium, a total of 3 L of artificial seawater (salinity: 30 ± 1), continuous aeration, and a natural photoperiod were used. The exposure medium for each condition was renewed weekly, after which EE2 concentration levels were re-established. Mortality was checked daily and found to be null. At the end of the 28-day exposure period, the clams were frozen in liquid nitrogen and stored at – 80 ºC. |
