All rights reserved.Cellular biomarkers of exposure and biological effects were measured in digestive gland of snails (Physa acuta) sampled in sites with 12 andwithout active volcanismin SãoMiguel Island (Azores).Metal content in digestive cell lysosomeswas determined by image analysis 13 after autometallography (AMG) as volume density of autometallographed black silver deposits (VvBSD). Lysosomal structural changes 14 (lysosomal volume, surface and numerical densities – VvLYS, SvLYS and NvLYS−, and surface-to-volume ratio – S/VLYS−) were 15 quantified by image analysis, after demonstration of β-glucuronidase activity, on digestive gland cryotome sections. Additional chemical 16 analyses (atomic absorption spectrophotometry) were done in the digestive gland of snails. The highestmetal concentrations were found 17 in snails from the active volcanic site, which agreed with high intralysomal VvBSD. Digestive cell lysosomes in snails inhabiting sites 18 with active volcanismresembled a typical stress situation (enlarged and less numerous lysosomes). In conclusion, the biomarkers used in 19 this work can be applied to detect changes in metal bioavailability due to chronic exposure to metals (volcanism), in combination with 20 chemical analyses.Centro de Investigação de Re- 430 cursos Naturais (CIRN, University of the Azores) and 431 Direcção Regional da Ciência e Tecnologia (Government 432 of the Azores) and by the Basque Government (ETOR- 433 TEK.ElsevierRepositório da Universidade dos AçoresZaldibar, BeñatRodrigues, ArmindoLopes, MarcoAmaral, AndréMarigómez, IonanSoto, Manu2012-05-16T11:11:57Z2006-122006-12-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.3/1359eng"Science of the Total Environment".
