Abstract(s)
Neste trabalho avaliou-se a exposição da população portuguesa a cádmio
(Cd), chumbo (Pb), arsénio (As), mercúrio (Hg) e nitrato (NO3
-) com base
na ocorrência destas substâncias nos alimentos e no consumo destes,
utilizando a metodologia dos Estudos de Dieta Total. A definição da
amostragem representativa do consumo alimentar da população foi realizada com base no estudo “Alimentação e estilos de vida da população
portuguesa” e os alimentos foram recolhidos, tratados e cozinhados para
serem analisados na forma "como consumido". Para estimar a exposição
da população aos contaminantes foi utilizado o programa MCRA (Monte
Carlo Risk Assessment). A percentagem da população portuguesa dos
18 aos 74 anos, de ambos os sexos, exposta a doses diárias superiores
às toleráveis/admissíveis, definidas pela Autoridade Europeia para a
Segurança dos Alimentos (EFSA, na sigla em inglês), foi inferior a 5 para o
cádmio e nitratos e inferior a 10 para o mercúrio. Para o arsénio e chumbo
a população portuguesa não ultrapassa os valores-guia.
The exposure of the Portuguese population to cadmium (Cd), lead (Pb), arsenic (As), mercury (Hg) and nitrates (NO3 -) was evaluated based on the occurrence of these substances in foods and their consumption, using the methodology of Total Diet Studies. The sample definition representative of the population's food consumption was based on the study “Food and lifestyles of the Portuguese population” and the foods were collected, treated and cooked to be analysed as “consumed”. To estimate population exposure to contaminants, the MCRA (Monte Carlo Risk Assessment) software was used. The percentage of the Portuguese population from 18 to 74 years of age, of both sexes, exposed to daily intakes above the tolerable / acceptable levels, defined by the European Food Safety Authority (EFSA), is less than 5 for cadmium and nitrates and less than 10 for mercury. For arsenic and lead, the Portuguese population does not exceed the guidance values.
