SETApp: A machine learning and image analysis based application to automate the sea urchin embryo test
(Elsevier, 2022-08)
[EN] Since countless xenobiotic compounds are being found in the environment, ecotoxicology faces an astounding challenge in identifying toxicants. The combination of high-throughput in vivo/in vitro bioassays with ...
Suspect Screening of Chemicals in Hospital Wastewaters Using Effect-Directed Analysis Approach as Prioritization Strategy
(MDPI, 2023-01-26)
The increasing number of contaminants in the environment has pushed water monitoring programs to find out the most hazardous known and unknown chemicals in the environment. Sample treatment-simplification methods and ...
Application of a Biological Multilevel Response Approach in the Copepod Acartia Tonsa for Toxicity Testing of Three Oil Water Accommodated Fractions
(Elsevier, 2021-06-01)
Abstract
Copepods play a critical role in the marine food webs, being a food source for marine organisms. In this study, we investigated the toxic effects of Water Accommodated Fractions (WAFs) from three types of oil: ...
Toxicity to sea urchin embryos of crude and bunker oils weathered under ice alone and mixed with dispersant
(Elsevier, 2022)
[EN] A multi-index approach (larval lenghthening and malformations, developmental disruption, and genotoxicity) was applied using sea-urchin embryos as test-organisms. PAH levels measured in the under-ice weathered aqueous ...
Influence of dispersant application on the toxicity to sea urchin embryos of crude and bunker oils representative of prospective oil spill threats in Arctic and Sub-Arctic seas
(Elsevier, 2021-09-09)
This study deals with the toxicity assessment of crude and bunker oils representative of prospective oil spill threats in Arctic and Sub-Arctic seas (NNA: Naphthenic North-Atlantic crude oil; MGO: Marine Gas Oil; IFO: ...
The role of sample preparation in suspect and non-target screening for exposome analysis using human urine
(Elsevier, 2023-10)
The use of suspect and non-target screening (SNTS) for the characterization of the chemical exposome employing human biofluids is gaining attention. Among the biofluids, urine is one of the preferred matrices since organic ...
Exploratory optimisation of a LC-HRMS based analytical method for untargeted metabolomic screening of Cannabis Sativa L. through Data Mining
(Elsevier, 2023-10)
Background
Recent increase in public acceptance of cannabis as a natural medical alternative for certain neurological pathologies has led to its approval in different regions of the world. However, due to its previous ...
Antioxidant activities and selenogene transcription in the european sea bass (Dicentrarchus labrax) liver depend, in a non-linear manner, on the Se/Hg molar tatio of the feeds
(Springer Nature ; Humana Press, 2021-07-01)
[EN] Feeding 3.9 and 6.7 mg Hg/kg (Se/Hg molar ratios of 0.8 and 0.4, respectively) for 14 days negatively affected Dicentrarchus
labrax growth and total DNTB- and thioredoxin-reductase (TrxR) activities and the transcription ...
Development of an analytical method for the simultaneous determination of 50 semi-volatile organic contaminants in wastewaters
(Elsevier, 2023-06-11)
This work describes the development of a robust analytical methodology for the simultaneous
determination of 50 semi-volatile organic compounds (SVOCs) in wastewater effluent samples
by solid-phase extraction (SPE) followed ...
Development and evaluation of a comprehensive workflow for suspect screening of exposome-related xenobiotics and phase II metabolites in diverse human biofluids
(Elsevier, 2024-01-13)
Suspect and non-target screening (SNTS) methods are being promoted in order to decode the human exposome since a wide chemical space can be analysed in a diversity of human biofluids. However, SNTS approaches in the ...
