A study has been performed to estimate the average and high (90th percentile of consumers-only) daily intakes of sorbates by age-sex groups (> 3 years old) in Korea. The estimation of daily intakes was based on individual-based dietary intake data in ‘National Health and Nutrition Survey in 1998’and the contents of sorbates from samples. The estimated daily intakes (EDI) of sorbates for average consumers ranged from 0.09 mg/kg/bw/day to 0.51 mg/kg bw/day corresponding to 0.4-2.1% of acceptable daily intake (ADI). For high consumers, the range of EDI of sorbates was 3.42-14.65 mg/kg bw/day corresponding to 13.7-58.6% of ADI. Foods that contributed most to the daily intakes of sorbates for all age-sex groups were processed fish products, processed meat products, and salted floods. There was an inverse relationship between age and the consumption of sorbates for average and high consumers, whereas no marked pattern was emerged by sex categories. The intake levels of sorbates even among high consumers were below the ADI in Korea.

In order to evaluate the acceptability of Korea and Codex maximum residue limits (MRLs), theoretical maximum daily intake (TMDI) by Korean population was calculated from MRL and food factor and compared with acceptable daily intake (ADI). The percent ratio of TMDI to ADI for 105 pesticides whose MRL was established in Korea was mostly below 80% and 13 pesticides exceeded the ADI. Among 82 pesticides with Codex MRL, 20 items exceeded the ADI. The main causes of exceeding the ADI according to Korea or Codex MRLs were pointed out for 22 items and it was needed to set measures to assure a safety margin.

Limited information is available on the acceptability of Korean MRLs(maximum residue limits) and the health risk based on the pesticide exposure by food intake. The aim of this study was to evaluate TMDI(theoretical maximum daily intake) and EDI(estimated daily intake) for Korean by using MRLs, food intake, residue data, and correction factors, and compare with ADI(acceptable daily intake) in order to estimate the health risk based on the pesticide exposure. The study was performed in three steps. In the frist step, the residual pesticides in each category of food were investigated using the pesticide residue analytical data(1995-96) from officially approved organizations and the analytical data for poultry was adopted from Korean food code method. In the second step, TMDI was estimated from MRLs and food factors, and was compared with ADI. In the third step, the effectiveness of each culinary treatment (washing, peeling, steaming, boiling, and salting) was evaluated and EDI was calculated using pesticide residue data, food factor, and correction factor by treatment. TMDI obtained from MRLs and food intake, and food intake was summed as 1,100.99 g, which was 79.1% of total consumption. The percent ratio of TMDI to ADI for 156 pesticides was mostly below 80% and only 30 pesticides exceeded the ADI. In particular, non-treated EDI from pesticide residue data and food intake was summed up to about 43 $\mu\textrm{g}$/day/capita, and the rank was procymidone(8.6 $\mu\textrm{g}$) > maleic hydrazide(8.2 $\mu\textrm{g}$) > EPN(3.7 $\mu\textrm{g}$) > deltamethrin(3.5 $\mu\textrm{g}$) > cypermethrin(3.0 $\mu\textrm{g}$). The treated EDI calculated from pesticide residue data, food intake, and correction factor by culinary treatment was summed up to 13.7 $\mu\textrm{g}$/day/captia. The percentage of ADI was TMDI(79.74%) > non-treated EDI (0.17%) > treated EDI (0.04%), and the exposure level of Korean population to whole pesticides was below the level to produce health risk. Oncogenic risk of five pesticides used in Korea whose oncogenic potency(Q*) was known were assessed from TMDI and treated EDI. Dietary oncogenic risk for Korean was estimated to be 2.0$\times$10-3 on the basis of TMDI, 8.3$\times$10-7 on the basis of treated EDI. The oncogenic risk from TMDI exceeded the risk level(1$\times$10-6) of EPA, whereas the oncogenic risk from treated EDI and real exposure level lower than that of EPA.

In this study, the daily intake of preservatives in the Korean population was estimated, using data from national health and nutrition studies regarding the concentration of preservatives in each type of food, food intake by sex, age group, and weight. The level of safety of these preservatives was evaluated via comparisons with the acceptable daily intake (ADI) data established by the Joint FAO/WHO expert committee on food additives (JECFA). The Estimated daily intake (EDI) of sorbic acid is 495.85 ${\mu}g$/kg bw, benzoic acid is 215.34 ${\mu}g$/kg bw and parahydroxybenzoate is 5.01 ${\mu}g$/kg bw per day each. Their percentages in relation to ADI are 2, 4.3, and 0.1%, respectively. The comparatively high-consuming groups were taking sorbic acid 1,012.06 ${\mu}g$/kg bw, benzoic acid 229.56 ${\mu}g$/kg bw, and parahydroxybenzoate 11.58 ${\mu}g$/kg bw per day, and their intake levels as a percentage of ADI were 4.1, 4.6, 0.1%, all within safe levels. Males were found to have taken more benzoic acid than women, whereas we detected no sighificant differences in the intakes of sorbic acid and parahydroxybenzoate between males and females. The EDI of sorbic acid, benzoic acid, and parahydroxybenzoate were lower than the ADI in all age groups studied.

BACKGROUND: Food Sanitary Act establishes Maximum Residue Limits (MRLs) of pesticides in food that are newly registered and used per each quarter, as stipulated by Agro-chemical Control Act. Current Food Code contains the MRLs for a total of 418 pesticides in 184 food types. METHODS AND RESULTS: National MRLs for pesticides have been established by based on scientific data of good agricultural practice, acceptable daily intake (ADI), food intake, average body weight and others. MRLs for pesticides are generally set under the principle that theoretical maximum daily intake (TMDI) are always below ADI. As results, 27 MRLs in agricultural products were newly proposed for 22 pesticides (fungicide: azoxystrobin, fludioxonil, fluquinconazole, flusilazole, iprovalicarb, kresoxim-methyl, mandipropamid, metconazole, pyraclostrobin, tebuconazole, triflumizole, etc., Insecticide: dinotefuran, flubendiamide, indoxacarb, cyhalothrin, spinetoram, thiacloprid, thiamethoxam, metaflumizone, etc., Acaricide(miticide): cyenopyrafen, lufenuron) in 2010. CONCLUSION(s): There is no intake concerns for establishment of pesticide MRLs on foods in this time. Because the ratio of theoretical maximum daily intake (TMDI) are set below that of ADI.

This study was carried out to monitor the current status of pesticide residues in selling agricultural products via online and assessed their safety in 2014. A total of 124 samples were purchased six times from March to August 2014 twenty online shopping malls randomly. These samples were analysed 208 pesticides by multiresidue method using a GC-ECD/NPD and a LC-MS/MS and confirmed by a GC-MSD. As a result of analysis, residual pesticides samples were 11 (8.9%) such as leek, young radish, welsh onion etc, of which 2 samples (1.6%) such as sesame bud (Chlorothalonil), artemisia (Chlorpyrifos) were violated Korea Maximum Residue limits (MRLs). 11 kinds of pesticides (19 times) were detected in 11 samples. Risk assessment evaluated human health exposure with the ratio of EDI (Estimated daily intake) to ADI (Acceptable daily intake) of pesticides detected. %ADI (the ratios of EDI to ADI) were 0.04~95.70% and some samples represented a fairly dangerous levels. In particular, Chlorothalonil in the sesame bud was shown as a significant risk close to 100% of %ADI. Accordingly, it is recommended to strengthen a safety check on agricultural products in online sales.

This study was carried out to measure the amount of daily intake on three synthetic food red colors (Amaranth: R2, Erythrosine: R3, Allura Red: R40) in foods by Korean. Analysis of three synthetic food red colors was conducted by HPLC with the foods including bread, confection, candy, alcoholic beverage, soft drink, ice cream, chocolate, and chewing gum. Recovery rates from the known concentrations of three standard food red colors which were spiked into foods were ranged from 85.1 to 100.4 (%) for each foods. Total Estimated Daily Intake (∑EDI) was from 0 to 1.632 mg/kg bw/day for each food item and from 0.512 to 7.281 mg/person/day for ages (1∼over 65 years old). The data of average food intake for each food item per person per day were obtained from the report of Korean National Nutrition Survey conducted by the Korea Ministry of Health and Welfare in 2001. Total EDI of each red colors per person per day were showed as follows; 0.742 mg/kg bw/day for R2, 0.391 mg/kg bw/day for R3 and 2.018 mg/kg bw/day for R40 as total amount respectively, and the ranges of these values were 0.5∼7.1% of FAO/WHO's Acceptable Daily Intake (ADI) values. Therefore, the amount of daily intake of three synthetic food red colors in Korea was regarded as safe.

Daily intakes of 14 preservatives were evaluated by using their maximum permitted levels(MPL) and national food disappearance data in 1998. The estimated daily intake (EDI) of each preservatives were compared with corresponding acceptable daily intakes (ADIs). EDIs of dehydroacetic acid, sodium dehydroacetate, $\rho$-hydrobenzoic acid ester, propionic acid, sodium propionate and calcium propionate were less than 2% of ADI and judged to be safe. However, EDI of sorbic acid and potassium sorbate were 76.61 mg/person/day and it reached 5% of its ADI.. EDI of benzoic acid and sodium benzoate were 85.65 mg/person/day and it reached 31% of its ADI. The highest intake of benzoic acid came from carbonated drink.

This study was conducted to develop an appropriate management for safety of children snacks. In this study, monitorings of food additives such as four kinds of sweeteners (sodium saccharin, aspartame, acesulfame potassium, sucralose) which are sold in children snacks at stationary store around the school were performed. 92 samples (34 ice cakes, 52 beverages and 6 candies) were analyzed for sweeteners. Contents of 4 kinds of sweeteners in ice cakes, beverages and candies were 0.41, 0.47, 0.00 mg/kg for sodium saccharin, 0.00, 20.54, 197.09 mg/kg for aspartame, 0.00, 28.10, 0.00 mg/kg for acesulfame potassium, 9.99, 1.40, 0.00 mg/kg for sucralose. Results of risk assessment for sweeteners were expressed as EDI (Estimated Daily Intake) comparing with ADI (Acceptable Daily Intake). The ratio of high risk group for sweeteners intake (95th) were 0~2.66%. The results of this study indicated that each EDI of four kinds of sweeteners sold at stationary stores around the school is much lower than each ADI in general. Consequently, the children snacks are thought to be safe for consumption.
