Conradi, Mercedes Maguilla, María Sánchez-Moyano, J Emilio Cunha, Marta Pereira, Camilo Dias Seabra Freitas, Rosa Animals Geologic Sediments Water Pollutants, Chemical Gasoline Gastropoda Feeding Behavior Environmental Monitoring Behavior, Animal Polycyclic Aromatic Hydrocarbons Diesel contamination is a pervasive threat to coastal ecosystems, yet the sublethal behavioural effects on benthic invertebrates remain poorly understood. We exposed the marine gastropod Tritia neritea to sediments spiked with two diesel concentrations (DIE-1: 1.4 × 10 ng/g; DIE-2: 3.5 × 10 ng/g) over 28 days to assess survival, foraging, predator-avoidance, burrowing, and biochemical responses. Diesel addition led to initial contamination dominated by heavy hydrocarbons, BTEX compounds, and naphthalene, with DIE-2 exceeding sediment quality guideline thresholds. Hydrocarbon concentrations declined sharply (>96% for C-C, >97% for LMW PAHs) over the experiment, reducing TEQ and MEQ values by > 99%. Despite chemical remediation, snails exposed to DIE-2 exhibited reduced survival (79 ± 7.5%), impaired foraging success ( |
