摘要
Surfactants are among the most common PPCPs that reach coastal systems, being often used in large quantities in cleaning products such as detergents and soap powders. Sodium lauryl sulfate (SLS) is listed in this group of emerging contaminants. Previous studies have already demonstrated the presence of SLS in aquatic environments and the negative effects on organisms living there. However, with ocean acidification and warming predictions, SLS-induced impacts may differ from those currently known. In this context, the present study aimed to reproduce environmental conditions by assessing the release of substances over a short period and to understand the influence of a rapid increase in temperature on the impacts caused. The marine bivalve Mytilus gallopro-vincialis was exposed to 2.0 mg/L SLS at 17 degrees C and 21 degrees C for 7 days. To assess the possible biochemical changes resulting from the exposure of mussels to SLS, a series of biomarkers related to oxidative stress/damage, detoxification, and metabolic capacity were measured. The SLS accumulation in soft tissues was low (about 0.7 ng/g) at both temperatures. The results evidenced increased metabolic activity, especially in mussels exposed to SLS at 17 degrees C. An increase in protein content was also observed upon exposure to SLS and increased temperature compared to controls at 17 degrees C. Although no effects on antioxidant enzymes were observed, protein damage was recorded, especially at 21 degrees C. These findings confirmed that SLS induces toxic effects and predicted climate change factors may increase the impact on M. galloprovincialis.
