Ionic Liquids (ILs) are currently applied in a wide variety of fields, with promising outcomes in microalgae high value biocompounds extraction. The occurrence of these compounds in natural water systems, with their characteristic stability and low biodegradability, becomes a threat worthy of attention. In the present study, Dunaliella tertiolecta, Isochrysis galbana and Rhinomonas reticulata were exposed to 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMIM] TfN) for 72, 168 and 264 h, at 20 and 25 °C.

However, their impact on marine invertebrates remains underexplored. This study investigated the responses at subcellular level in the Mediterranean mussel () exposed to three veterinary FQs, marbofloxacin (MARB), sarafloxacin (SARA), and difloxacin (DI), at concentrations considered relevant to environmental conditions.

Among these pressures, there has been an increasing concern towards UV filters occurrence in aquatic ecosystems due to a greater use of personal care products (PCPs). 2-ethylhexyl-4-methoxycinnamate (EHMC) is one of the most used UV filters in sunscreen formulations, yet few reports address its effects in biota.

The increasing UV-filter incorporation in daily-life products raises concerns about their potential impact on marine-coastal environments upon release. As stressors rarely act alone, global change-induced factors, such as ocean acidification (OA), can amplify ecological hazards promoted by contaminants in coastal realms.

In vitro exposure was performed on subcellular fractions of the digestive gland and gills through a multi-biomarker approach, which included the assessment of cellular damage, antioxidant and biotransformation enzyme activities, neurotoxicity, and DNA single-strand breaks (DNAssb). Results showed a decrease in protein carbonyl content in the gills when exposed to all concentrations of ENR.
