Mycotoxins Exposure in Cabinda, Angola-A Pilot Biomonitoring Survey of Breastmilk
Duarte, Sofia; Silva, Liliana J. G.; Pereira, André; Gimbi, Marta; Cesar, Cristiane; Vidal, Vanessa; Basílio, Rita; Almeida, Anabela; Lino, CelesteBreast milk is considered the ideal form of nutrition for newborns and infants. However, it can carry over contaminants, namely mycotoxins, with biological effects to which this population is particularly vulnerable. Human biomonitoring and surveillance programs are particularly scarce in low-income countries, where food security is a more urgent priority in comparison with food safety. This pilot survey aims t...
Human Biomonitoring of Selected Hazardous Compounds in Portugal: Part I-Lessons...
Pena, Angelina; Duarte, Sofia; Pereira, André M. P. T.; Silva, Liliana J. G.; Laranjeiro, Célia S. M.; Oliveira, Marta; Lino, Celeste; Morais, SimoneHuman biomonitoring (HBM) data provide information on total exposure regardless of the route and sources of exposure. HBM studies have been applied to quantify human exposure to contaminants and environmental/occupational pollutants by determining the parent compounds, their metabolites or even their reaction products in biological matrices. HBM studies performed among the Portuguese population are disperse and...

An overview of analytical methodologies for the determination of antibiotics in...
Seifrtová, Marcela; Nováková, Lucie; Lino, Celeste; Pena, Angelina; Solich, PetrThe widespread occurrence of antibiotics as contaminants in the aquatic environment has increased attention in the last years. The concern over the release of antibiotics into the environment is related primarily to the potential for the development of antimicrobial resistance among microorganisms. This article presents an overview of analytical methodologies for the determination of quinolone (Qs) and fluoroqu...
Evaluation of organochlorine pesticide residues in human serum from an urban an...
Cruz, Susana; Lino, Celeste; Silveira, Maria IreneOrganochlorine pesticide residues were measured in human serum from an urban and two rural populations in Portugal, in an attempt to evaluate the contamination level of Portuguese population. Serum levels of 12 residues were determined using a validated methodology that included gas chromatography-electron-capture detection. It was made an attempt to point out the differences of contamination between rural and ...
Determination of ticlopidine in human plasma by capillary gas chromatography wi...
Pena, Angelina; Lino, Celeste; Silveira, M. Irene N.A gas chromatographic method for determination of ticlopidine in human plasma using mass spectrometric detection was developed. A Perkin Elmer model 8500 gas chromatograph coupled to an ion trap detector (ITD) in electron impact mode (EI) was used. The gas chromatograph was fitted with a 30 m×0.32 mm i.d., DB-17 capillary column with a film thickness of 0.25 [mu]m. The compounds were isolated from plasma by Ext...
Assessment of Pesticide Residues in Honey Samples from Portugal and Spain
Blasco, Cristina; Fernández, Mónica; Pena, Angelina; Lino, Celeste; Silveira, Mª Irene; Font, Guillermina; Picó, YolandaFifty samples of honey collected from local markets of Portugal and Spain during year 2002 were analyzed for 42 organochlorine, carbamate, and organophosphorus pesticide residues. An analytical procedure based on solid-phase extraction with octadecyl sorbent followed by gas chromatography−mass spectrometry (GC−MS), for organochlorines, and by liquid chromatography−atmospheric pressure chemical ionization-mass s...
