英文摘要	Dichlofluanid is a fungicide employed as a booster biocide in antifouling paints, but information its toxicity to aquatic organisms is scarce. This study aims to evaluate biomarker responses in the mussel Perna perna exposed to dichlofluanid. Mussels were exposed to 0 (control), 0.1 μg/L (environmental concentration), 10, and 100 μg/L of dichlofluanid for 24 and 96 h. Byssus formation, oxygen consumption, and oxidative stress response were evaluated in gills and digestive glands. The results demonstrated that even the lowest dichlofluanid concentration causes a reduction in byssus biomass and water content. The higher concentrations caused an acute increase in oxygen consumption, which only returned to control levels after 96 h of exposure. ACAP levels and antioxidant enzyme activities were affected in both tissues with a larger effect observed in gill tissues as demonstrated by the IBR index. The overall results demonstrated that environmentally relevant concentrations of dichlofluanid would be deleterious to aquatic organisms. © 2020 Elsevier Ltd
