Abstract

Surfactants are among the most common PPCPs that reach coastal systems, indeed they are often used in large quantities in cleaning products such as detergents and soap powders. Sodium lauryl sulphate (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 predictions of ocean acidification and warming, SLS-induced impacts may be different 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 galloprovincialis was exposed to 2.0 mg/L SLS at 17 °C and 21 °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-1) at both temperatures. The results evidenced increased metabolic activity, especially in mussels exposed to SLS at 17 °C. An increase in protein content was also observed upon exposure to SLS and increased temperature compared to controls at 17 °C. Although no effects on antioxidant enzymes were observed, protein damage was recorded, especially at 21 °C. These findings confirmed that SLS induces toxic effects and predicted climate change factors may increase the impact on Mytilus galloprovincialis.
