Development and application of an analytical method to quantify odour removal in plastic waste recycling processes
Effects of the water-soluble fraction of a crude oil on freshwater meiofauna and nematode assemblages.
Published in Ecotoxicology and environmental safety
Oil water-soluble fractions (WSFs) compounds have low persistence in water; evaporating in a matter of hours to days. Nonetheless, they pose high toxicity to exposed biota. Their effects may be instantaneous or delayed, affecting, respectively, mainly survival vs growth and reproduction. We investigated the effects of crude oil WSFs on freshwater m...
Development of an analytical method to detect short-chain fatty acids by SPME-GC-MS in samples coming from an in vitro g...

Short chain fatty acids (SCFA) are end-products of intestinal bacterial fermentation. The concentrations of fermentation metabolites are closely related to the microbial activity that occurs in various digestive compartments. The fermentation products may vary qualitatively and quantitatively, especially within the colon. The Simulator of the Human...
Effects of the water-soluble fraction of a crude oil on estuarine meiofauna : a microcosm approach
Although soluble hydrocarbons persist for only hours to days in aquatic environments, they potentially pose a high toxicity to aquatic biota. Here we investigate effects of the water-soluble fraction (WSF) of crude oil on estuarine meiofauna, with special focus on nematodes. Copepods and amphipods were the most sensitive taxa, disappearing almost c...
Dynamic headspace analysis using online measurements : modeling of average and initial concentration
Dynamic headspace sampling is an important technique for the analysis of consumer products, the study of biological samples and environmental water analyses. This paper shows the influence of experimental conditions, such as the sampling time, sampling flow rate, headspace volume, liquid volume and Henry coefficient on the measured average concentr...
Hydrophilic divinylbenzene for equilibrium sorption of emerging organic contaminants in aquatic matrices
Hydrophilic divinylbenzene (DVB) (Bakerbond) has surfaced as a promising sorbent for active sampling of analytes from aqueous matrices over a very broad polarity range. Given this, hydrophilic DVB may likewise offer potential for passive sampling, if sorbent/water partitioning coefficients (K-sw) were to be available. In this work, static exposure ...
Microbiological, chemical and sensory spoilage analysis of raw Atlantic cod (Gadus morhua) stored under modified atmosph...
...Published in Food microbiology
During fish spoilage, microbial metabolism leads to the production of volatile organic compounds (VOCs), characteristic off-odors and eventual consumer rejection. The aim of the present study was to contribute to the development of intelligent packaging technologies by identifying and quantifying VOCs that indicate spoilage of raw Atlantic cod (Gad...
Clinical application of microsampling versus conventional sampling techniques in the quantitative bioanalysis of antibio...
Published in Bioanalysis
Conventional sampling techniques for clinical pharmacokinetic studies often require the removal of large blood volumes from patients. This can result in a physiological or emotional burden, particularly for neonates or pediatric patients. Antibiotic pharmacokinetic studies are typically performed on healthy adults or general ward patients. These ma...
Formulation approaches to reduce post-application pesticide volatilisation from glass surfaces
Direct toxicity of the water-soluble fractions of a crude and a diesel-motor oil on the survival of free-living nematode...
The water-soluble fraction (WSF) of an oil contains different classes of petroleum hydrocarbons and, despite their low potential for bioaccumulation, these can be highly toxic to biota. Nematodes are usually the most abundant and species-rich group of metazoans in marine and freshwater sediments as well as terrestrial soils and have been proposed a...
