  • Dietary Exposure to acrylamide from potato crisps to Spanish population
    Food Additives and Contaminants, 2009
    Co-Authors: Gema Arribas-lorenzo, Francisco Jose Morales
    Abstract:

    Potato crisps are one of the most contributing food commodities to overall Dietary Exposure of acrylamide to human. This investigation is aimed to evaluate the Dietary Exposure to acrylamide form potato crisps in the Spanish population. A sampling of potato crisps (n = 36) from 16 different producers were carried put in March 2008. An average level of 740 µg/kg (ranging from 81 to 2622 µg/kg; min:max) and a median of 592 µg/kg were obtained. Acrylamide levels in marketed potato crisps have been significantly reduced (nearly to 50%) as compared with a previous sampling performed 4 years ago. Observed signal value (90th percentile) is settled at 1377 µg/kg and 86% of the samples with acrylamide levels lower than 1000 µg/kg. Dietary Exposure to acrylamide from potato crisp consumption in total Spanish population was determined to be 0.042 µg/kg•bw/day by using a deterministic approach based on National consumption database. In a second study, Dietary Exposure (based on 3-day food record) was determined at 0.053 µg/kg•bw/day for the adult population (17-60 years) and 0.142 µg/kg•bw/day for children (7-12 years). Contribution of potato crisps to the estimated Dietary acrylamide Exposure of Spanish population is moderate as compared with other European member states.

  • Dietary Exposure to acrylamide from potato crisps to the Spanish population
    Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2009
    Co-Authors: Gema Arribas-lorenzo, Francisco Jose Morales
    Abstract:

    Potato crisps are one of the food commodities that contribute most to overall Dietary human Exposure of acrylamide. This investigation has estimated the Dietary Exposure to acrylamide form potato crisps in the Spanish population. Sampling of potato crisps (n = 36) from 16 different producers were carried out in March 2008. An average level of 740 µg kg−1 (ranging from 81 to 2622 µg kg−1; minimum to maximum) and a median of 592 µg kg−1 were obtained. Acrylamide levels in marketed potato crisps have been significantly reduced (nearly to 50%) compared with a previous sampling performed 4 years earlier. The observed signal value (90th percentile) was 1377 µg kg−1 with 86% of the samples with acrylamide levels lower than 1000 µg kg−1. Dietary Exposure to acrylamide from potato crisp consumption in the total Spanish population was estimated to be 0.042 µg kg−1 body weight day−1 by using a deterministic approach based on the National consumption database. In a second study, Dietary Exposure (based on a 3-day foo...

  • Research advances on Polychlorinated Biphenyls Dietary Exposure and health risk assessment
    Environmental Chemistry, 2014
    Co-Authors: Zhu Xiaolo
    Abstract:

    As the synthetic chlorinated persistent organic pollutants( POPs) in the environment, polychlorinated biphenyls( PCBs) can easily accumulate and transfer in the food chain through bioconcentration,which could pose a great threat to human body health. Previous studies have shown that food consumption is the most important route of human Exposure to PCBs. Therefore many developed countries gradually conducted studies to evaluate local residents Dietary Exposure to PCBs via Dietary intake. This paper summarizes the advances on both domestic and foreign general population Dietary Exposure levels of PCBs and their health risk assessment,thus to provide reference for further research.

  • Dietary Exposure of Hong Kong adults to nitrate and nitrite from vegetable intake.
    Food additives & contaminants. Part B Surveillance, 2011
    Co-Authors: M.y.y. Chen, Stephen W.c. Chung, Jeff C. H. Tran, Katherine Siu-kuen Tong, Constance Hon-yee Chan, Ying Xiao
    Abstract:

    The aim of this study was to assess the Dietary Exposure of adults in Hong Kong to nitrate and nitrite from vegetables. If all vegetables consumed were raw, the Dietary Exposure to nitrate for average consumers was estimated to be 4.4 mg kg−1 body weight (bw) day−1 and, for high consumers, was estimated to be 13 mg kg−1 bw day−1, which is about 120 and 350% of acceptable daily intake (ADI), respectively. If all vegetables consumed were cooked, the Dietary Exposure to nitrate from vegetables for the average adult consumer was estimated to be 3.5 mg kg−1 bw day−1 and, for high consumer, was estimated to be 10 mg kg−1 bw day−1, which is about 95 and 270% of ADI, respectively. On the other hand, the Dietary Exposure to nitrite from vegetables for average and high consumers were well below the ADI.

  • Dietary Exposure of secondary school students in Hong Kong to benzoic acid in prepackaged non-alcoholic beverages
    Food additives & contaminants. Part A Chemistry analysis control exposure & risk assessment, 2009
    Co-Authors: Ka Ming, Stephen W.c. Chung, Cheok Man Chan, Ying Xiao
    Abstract:

    This study evaluated the Dietary Exposure of secondary school students in Hong Kong to benzoic acid from pre-packaged non-alcoholic beverages. Exposure was estimated using local food consumption data of secondary school students obtained by a semi-quantitative food frequency questionnaire in 2000 and the benzoic acid level detected in pre-packaged beverages, including soft drink (both diet/light and regular types), fruit juice, soy milk, Chinese tea and coffee/tea) available locally in late 2006. The estimated Dietary Exposure to benzoic acid from pre-packaged beverages of average and high consumers (95(th) percentile) was 0.31 and 0.97 mg kg(-1) bw day(-1), respectively. These Exposures accounted for 6.1 and 19.3% of the acceptable daily intake (ADI: 0-5 mg kg(-1) bw) of benzoic acid for average and high consumers, respectively. As in other countries, soft drinks contributed most to Dietary Exposure to benzoic acid from pre-packaged beverages in Hong Kong.

  • Dietary Exposure to chloropropanols of secondary school students in Hong Kong.
    Food additives & contaminants. Part B Surveillance, 2008
    Co-Authors: J.c.w. Yau, K.p. Kwong, Stephen W.c. Chung, Ying Xiao
    Abstract:

    This paper reports levels of 3-monochloropropan-1,2-diol (3-MCPD) and 1,3-dichloro-2-propanol (1,3-DCP) in a wide range of food items and estimates their Dietary Exposure for secondary school students in Hong Kong. Dietary Exposure to chloropropanols was estimated using local food consumption data obtained from secondary school students in 2000 and the concentrations of 3-MCPD and 1,3-DCP in food samples taken from the local market. The Dietary Exposure to 3-MCPD for an average secondary school student consumer was estimated to be 0.063–0.150 µg kg−1 body weight (bw) day−1, whilst that for the high consumer was 0.152–0.300 µg kg−1 bw day−1. Both estimates fell below the provisional maximum tolerable daily intake of 2 µg kg−1 bw established by the Joint Expert Committee on Food Additives (JECFA) and amounted to less than 20% of this safety reference value. The Dietary Exposure to 1,3-DCP for an average secondary school student consumer was estimated to be 0.003–0.019 µg kg−1 bw day−1, whilst that for the h...
