We investigated stage-specific metabolic responses of blue mussel (<em>Mytilus edulis</em>) larvae to shipping-related noise, chemical pollution, and their combination using untargeted nuclear magnetic resonance-based metabolomics.</p><p>Metabolic profiles were analysed in D-larvae and post-larvae exposed to noise or chemical pollution, as well as in post-larvae originating from chemically exposed embryos and subsequently subjected to acoustic stress during metamorphosis. Stress-response axes were characterised using orthogonal partial least squares–discriminant analysis.</p><p>During embryogenesis, acoustic and chemical stressors elicited largely overlapping metabolic responses, dominated by modulation of free amino acid pools and nitrogen-related pathways. In contrast, post-larvae showed marked differences between stressors. Acoustic exposure was associated with increased metabolic turnover and mobilisation of energetic substrates, whereas embryonic chemical exposure led to persistent metabolic limitations during metamorphosis, reflected by altered energy balance and membrane-associated metabolites. Under combined exposure, post-larval metabolic profiles closely resembled those induced by chemical stress alone, indicating dominance of chemical-driven effects rather than additive responses.</p><p>Together, these results demonstrate that developmental stage strongly conditions metabolic sensitivity to shipping-related stressors and that early chemical exposure can alter metabolic plasticity during later life stages.</p>","dates":{"publication":"2026-06-15","submission":"2026-02-27"},"accession":"MTBLS13945","cross_references":{"MetaboLights":["MTBLC69061","MTBLC229203","MTBLC15891","MTBLC18132","MTBLC16958","MTBLC57606","MTBLC13705","MTBLC18237","MTBLC28300","MTBLC16449","MTBLC16027","MTBLC15751","MTBLC16264","MTBLC16668","MTBLC9349","MTBLC17287","MTBLC16856","MTBLC22660","MTBLC24996","MTBLC17306","MTBLC4167","MTBLC17750","MTBLC15355","MTBLC32664","MTBLC57926","MTBLC32861","MTBLC25017","MTBLC17822","MTBLC57947","MTBLC29995","MTBLC17724","MTBLC15354","MTBLC31298","MTBLC25094","MTBLC26271","MTBLC17126","MTBLC28044","MTBLC16947","MTBLC30031","MTBLC173941","MTBLC17191"],"ChEBI":["CHEBI:69061","CHEBI:229203","CHEBI:15891","CHEBI:18132","CHEBI:16958","CHEBI:57606","CHEBI:13705","CHEBI:18237","CHEBI:28300","CHEBI:16449","CHEBI:16027","CHEBI:15751","CHEBI:16264","CHEBI:16668","CHEBI:9349","CHEBI:17287","CHEBI:16856","CHEBI:22660","CHEBI:24996","CHEBI:17306","CHEBI:4167","CHEBI:17750","CHEBI:15355","CHEBI:32664","CHEBI:57926","CHEBI:32861","CHEBI:25017","CHEBI:17822","CHEBI:57947","CHEBI:29995","CHEBI:17724","CHEBI:15354","CHEBI:31298","CHEBI:25094","CHEBI:26271","CHEBI:17126","CHEBI:28044","CHEBI:16947","CHEBI:30031","CHEBI:173941","CHEBI:17191"]}}
