Passive sampling is easy to handle and shows potential for this purpose. However, studies in vivo are scarce, and kinetic parameters governing analyte partitioning between tissue and samplers remain poorly characterized. In this study, the silicone rubber membranes (SRMs) were exposed to fish fillet from common carp (Cyprinus carpio) to determine bioaccumulation parameters based on dissipation modelling using performance reference compounds (PRCs). The SRM was implanted in vivo in fish, and the dissipated PRCs were measured and applied to a mono-compartmental model. The results in fish fillet showed a pseudo-first kinetic order, and the plateau was attained at a time &gt; 30 h. However, the equilibrium may not be ensured because of the low lipid fraction (fl) in fish (4.5%), which could lead to a local saturation of the tissue in contact with the SRM. The ratio between elimination and uptake constants (Ke\/Ku) showed faster PAHs\u2013SRM sorption than PAHs-fish tissue sorption (200 times); thus, fish with low fl will lead to faster SRM sorption. By contrast, in fish with higher fl, the long-term exposures will be necessary. The percentage of released deuterated PAHs from SRM during in vivo fish exposure was 1.6 times higher than that observed in the fish fillet, indicating an active clearance process. Therefore, during implantation, the rate of clearance and the fl should be considered to ensure detectable levels for applying the integrative equation based on dissipation modelling.<\/jats:p>","DOI":"10.3390\/jox16010032","type":"journal-article","created":{"date-parts":[[2026,2,10]],"date-time":"2026-02-10T12:07:06Z","timestamp":1770725226000},"page":"32","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["In Vivo Passive Sampling Implantation in Fish for Monitoring of PAHs: Calibration and Kinetics"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5348-6230","authenticated-orcid":false,"given":"Jhon Fredy","family":"Narv\u00e1ez Valderrama","sequence":"first","affiliation":[{"name":"Grupo de Investigaci\u00f3n Ingeniar, Facultad de Ingenier\u00edas, Corporaci\u00f3n Universitaria Remington, Calle 51 No. 51-27, Medell\u00edn 050012, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3654-6710","authenticated-orcid":false,"given":"Juan Jos\u00e9","family":"Garc\u00eda Londo\u00f1o","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n Materialograf\u00eda, Transici\u00f3n Energ\u00e9tica y Ambiente (MATREA), Facultad de Ingenier\u00edas, Corporaci\u00f3n Universitaria Remington, Calle 51 No. 51-27, Medell\u00edn 050012, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2026-2828","authenticated-orcid":false,"given":"Daniel","family":"Gil Ram\u00edrez","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda, Universidad de la Sabana, Ch\u00eda 250017, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3875-1566","authenticated-orcid":false,"given":"Clara S.","family":"Arias-Monsalve","sequence":"additional","affiliation":[{"name":"Grupo en Salud Familiar y Comunitaria, Facultad de Ciencias de la Salud, Corporaci\u00f3n Universitaria Remington, Calle 51 No. 51-27, Medell\u00edn 050012, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8462-1124","authenticated-orcid":false,"given":"Jorge L.","family":"Gallego","sequence":"additional","affiliation":[{"name":"Biodiversity, Biotechnology and Bioengineering Research Group GRINBIO, Department of Engineering, University of Medellin, Medell\u00edn 050026, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"120904","DOI":"10.1016\/j.envpol.2022.120904","article-title":"Occurrence, sources, and spatial variation of POPs in a mountainous tropical drinking water supply basin by passive sampling","volume":"318","author":"Echeverri","year":"2023","journal-title":"Environ.
