Avaliação da qualidade das águas balneares do distrito de Bragança nos períodos...
Teixeira, Cristina; Fernandes, Nazaré; Carvalho, Raquel; Fernandes, telma; Afonso, Eugénia; Montanha, Maria José; Nogueira, António José M.A monitorização da qualidade das águas recreativas é fundamental, uma vez que este tipo de água representa potenciais fontes de infeção por microrganismos e outras substâncias que podem causar doenças. As águas das praias, incluindo as fluviais, devem atender a critérios de segurança para a prática balnear, com avaliação de parâmetros microbiológicos tais como Escherichia coli, Enterococos e Salmonella. Este es...

Valorization of fruit distillation pomaces
Serra, Lara; Pitacas, F.I.; Pedro, Soraia; Pires, Bruno; Fernandes, Tiago; Luís, Ângelo; Gallardo, Eugenia; Anjos, O.This study aims to characterise the nutritional composition of distillation pomace from the production of spirits from apple, pear and strawberry tree fruits (STFs) and to assess its potential for valorisation within circular economy and zero waste strategies. Pomace samples were collected after distillation at a distillery in Castelo Branco. Two batches per fruit type, each with three replicates, were analysed...
Characterisation of Cannabis-Based Products Marketed for Medical and Non-Medica...
Pires, Bruno; Oliveira, Patrik; Simão, Ana Y.; Reis, João; Ramos, Sofia; Duarte, Ana Paula; Margalho, Cláudia; Rosado, Tiago; Barroso, MárioCannabis-based products have gained attention in recent years for their perceived therapeutic benefits (with cannabinoids such as THC and CBD) and widespread availability. However, these products often lack accurate labelling regarding their cannabinoid content. Our study, conducted with products available in Portugal, revealed significant discrepancies between label claims and actual cannabinoid compositions. ...
Volumetric Absorptive Microsampling in Toxicology
Pires, Bruno; Catarro, Gonçalo; Soares, Sofia; Gonçalves, Joana; Rosado, Tiago; Barroso, Mário; Araujo, André R. T. S.; Gallardo, EugeniaVolumetric absorptive microsampling (VAMS) is an emerging technique in clinical and forensic toxicology. It is recognized as a promising alternative to traditional sampling methods, offering an accurate and minimally invasive means of collecting small volumes of biological samples, such as blood, urine, and saliva. Unlike conventional methods, VAMS provides advantages in terms of sample stability, storage, and ...
Microextraction action by packed sorbent in forensic drug analysis
Rosado, Tiago; Pelixo, Rodrigo; Pires, Bruno; Catarro, João Miguel; Rosendo, Luana M.; Brinca, Ana T.; Antunes, Mónica; Soares, Sofia; Simão, Ana Y.Microextraction by packed sorbent (MEPS) efficiently combines extraction, pre-concentration, and cleanup in a single device comprising two parts: the MEPS syringe and the packed sorbent bed1. MEPS has been used for several bioanalytical applications, including extraction of endogenous metabolites, biomarkers, and drugs from biological samples. It is particularly useful in metabolomics and pharmacokinetic studie...
Evaluation of hair hydrolysis and MEPS columns for the detection of amphetamine...
Pires, Bruno; Simão, Ana Y.; Rosado, Tiago; Gallardo, Eugenia; Barroso, MárioIntroduction: Different extraction and cleanup procedures have been used to identify amphetamines in hair samples. The microextraction by packed sorbent (MEPS), a miniaturized approach of the classic solid-phase extraction (SPE), has only been used so far to determine the presence of amphetamine (AMP) and methamphetamine (MAMP) in hair. The aim of this work was to evaluate different hair sample extraction condi...
Determination of amphetamine-related drugs in hair using MEPS as sample clean-up
Pires, Bruno; Simão, Ana Y.; Rosado, Tiago; Gallardo, Eugenia; Barroso, MárioIntroduction and aims: Different extraction and clean-up protocols have been used for amphetamine-related compounds determination in hair. Microextraction by packed sorbent (MEPS) is a miniaturized version of solidphase extraction (SPE) which has been applied to determine a number of drugs in hair (e.g., opiates, cocaine, ketamine, etc.) [1-4]. However, concerning amphetamine-related drugs, MEPS has only been u...
Sensors in the Detection of Abused Substances in Forensic Contexts: A Comprehen...
Rosendo, Luana M.; Antunes, Mónica; Simão, Ana Y.; Brinca, Ana Teresa; Catarro, Gonçalo; Pelixo, Rodrigo; Martinho, João; Pires, Bruno; Soares, Sofiaorensic toxicology plays a pivotal role in elucidating the presence of drugs of abuse in both biological and solid samples, thereby aiding criminal investigations and public health initiatives. This review article explores the significance of sensor technologies in this field, focusing on diverse applications and their impact on the determination of drug abuse markers. This manuscript intends to review the tran...
Determination of amphetamine-type psychostimulants in hair samples using MEPS a...
Pires, Bruno; Simão, Ana Y.; Rosado, Tiago; Gallardo, Eugenia; Barroso, MárioNumerous protocols for the analysis of amphetamine-type psychostimulants (ATS) in hair have been employed over the years. Microextraction by packed sorbent (MEPS), a downsized version of solid-phase extraction (SPE), has been effectively applied in hair drug analysis, including substances like opiates, cocaine, and ketamine. However, concerning ATS, MEPS has primarily been used to the determination of amphetami...
