Ocean acidification (OA) associated with climate change is expected to lower the ocean’s pH by 0.5 units 2100. Whilst effects such as coral bleaching and shell calcification are well documented, lesser-known impacts ‘invisible’ on animal sensory systems. Olfactory disruption behaviour towards chemical cues in many marine species, including crustaceans. We examine of microplastic odour additional stressors European green crab C. maenas. Using uridine diphosphate (UDP) triphosphate (UTP) a sex pheromone bouquet, glutathione (GSH) food cue, polyethylene (PE) plastic odour, were mixed carboxycellulose create slow-release gels. Crabs exposed gels seawater values 8.2, 7.6, 7.2. took longer react all odours reduced conditions (pH 8.2 7.2, p = 0.0017). At low pH, PE-exposed crabs exhibited attraction changed behavioural responses burying. The study confirms disruptive olfaction highlights that derivatives can become more bioactive at levels, potentially increasing threat posed pollution. Further research required determine potential long-term combined microplastics environment.
