Avaliação da exposição ao mercúrio no primeiro estudo da dieta total harmonizad...

O objetivo deste estudo foi estimar a exposição da população portuguesa ao metilmercúrio e mercúrio inorgânico, usando uma metodologia harmonizada de Estudos de Dieta Total (TDS), e avaliar o risco de exceder a Dose Semanal Admissível (DSA) (1,3 e 4 µg/kg de peso corporal/ semana, respetivamente). Amostras de alimentos representativas do padrão alimentar da população foram preparadas de acordo com os hábitos de...

Mercury exposure assessment from the first harmonised Total Diet Study in Portugal

The aim of this study was to estimate the Portuguese population’s baseline exposure to methyl and inorganic mercury by a harmonised total diet study (TDS) methodology and the risk of exceeding the Tolerable Weekly Intake (TWI). TDS food samples representative of the whole diet of the population were prepared as consumed, and analysed for total mercury. European Food Safety Authority’s (EFSA) conservative approa...

Monitorização da ingestão de aditivos alimentares: ferramentas de avaliação do ...

Com a mudança nos hábitos alimentares dos consumidores ao longo do tempo e a crescente disponibilidade de alimentos processados, tornou-se difícil evitar este tipo de produtos. Esta tendência pode levar a um aumento da ingestão de aditivos alimentares pela população. Neste contexto, com o objetivo de implementar um sistema de monitorização da ingestão de aditivos alimentares pela população portuguesa, no âmbito...

The first harmonised total diet study in Portugal: Vitamin D occurrence and int...

Vitamin D acts in calcium and phosphate homeostasis and also as an immunomodulatory hormone. To estimate the vitamin D intake by the ‘adults’ and ‘elderly’ Portuguese populations TDS methodology was used, since in the absence of skin UVB exposure, food and supplements are the only vitamin D sources. Vitamin D was quantifiable in 78 (24 from the fish group) of the 164 TDS samples. Sea bream contained the most vi...

Harmonized human biomonitoring in European children, teenagers and adults: EU-w...

As one of the core elements of the European Human Biomonitoring Initiative (HBM4EU) a human biomonitoring (HBM) survey was conducted in 23 countries to generate EU-wide comparable HBM data. This survey has built on existing HBM capacity in Europe by aligning national or regional HBM studies, referred to as the HBM4EU Aligned Studies. The HBM4EU Aligned Studies included a total of 10,795 participants from three ...

Bioaccessibility data of potentially toxic elements in complementary foods for ...

The introduction of complementary foods (CFs) is a critical step in an infant's transition to solid foods, providing essential nutrients beyond breast milk. However, CFs may contain potentially toxic elements (PTEs), such as arsenic and cadmium that pose health risks to infants. In this context, understanding the bioaccessibility of PTEs is vital as it determines the fraction of a contaminant released from the ...

The first harmonised total diet study in Portugal: Nitrate occurrence and expos...

A harmonised TDS methodology was used to assess the Portuguese population’s nitrate baseline dietary exposure and the risk of exceeding the Acceptable Daily Intake (ADI). Nitrate occurrence in 164 TDS samples pooled based on 20 FoodEx2 groups, representative of 18 to 75 years old population diet, was determined using UV-HPLC. The ‘vegetables’ group had the highest mean nitrate concentration (353 mg/kg), followe...

Biomonitorização humana de micotoxinas no âmbito do projeto HBM4EU: um estudo s...

As micotoxinas são toxinas naturais produzidas por fungos, apresentando efeitos tóxicos para o homem e para os animais. Reconhece-se, atualmente, que as alterações climáticas terão impacto na distribuição geográfica de algumas espécies de fungos produtores de micotoxinas o que se traduzirá, previsivelmente, num aumento da exposição humana a estes compostos. Pelas razões descritas, urge conhecer a atual exposiçã...
