OBJECTIVESTo investigate the change of pesticide residues in Chinese dietary through analysis on results of the pesticide residues in the Chinese total diet study carried out the first in 1990.

METHODSOrganochlorine, such as HCH and DDT of 9 groups and 15 organophosphorus pesticide residues of 3 groups in four regions of China were determined by gas chromatography-electron capture detector (GC-ECD) and gas chromatography-flame photometric detector (GC-FPD) respectively. According to the amount of pesticide residues in various foods and the amount of food consumption in different areas, we calculated the amount of dietary intake of pesticide residues, then compared with the acceptable daily intake (ADI) or provisional tolerable daily intake (PTDI). The contaminated samples were validated by gas chromatography-mass spectrometry (GC-MS).

RESULTSResults showed that the total dietary daily intake of HCH per person was decreasing from 5.04 micro g in 1990 to 3.11 micro g in 2000, where as the total dietary daily intake of DDT per person was decreasing from 20.47 micro g in 1990 to 2.15 micro g in 2000. The result was less than 1 percent difference of PTDI (0.01 mg/kg bw) established by the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) in 2000. Compared to the results in 1990, the intake of HCH from animal foods increased a little, due to the contaminated of aquatic products by Lindan in the second Southern region and the first Northern region. None of the organophosphorous pesticide residues analyzed were detected in cereals, vegetables and fruits.

CONCLUSIONThe intake level of pesticide residues in Chinese dietary in 2000 was considered to be low, and the abuse of organophosphorous pesticide seemed to be under effective control.

PURPOSE: The purpose of this study was to investigate the relationship between acute diarrheal disease and causative seafood. METHODS: This study was done retrospectively by investigating age, sex, symptoms, and causative seafoods in 140 patients. Correlating symptoms were vomiting, abdominal pain, fever, and bloody diarrhea. Causative seafood were crab, spiny lobster, pickles, sliced raw fish, and shellfish. All patients was seen at our hospital between September and November in two consecutive years, 2000 and 2001. RESULTS: An characteristic of seafood related food poisoning was an age of 30 or older. The major cause of seafood related food poisoning was crab. The most common symptom of seafood related food poisoning was abdominal pain. Symptom of crab relate food poisoning was most severe. CONCLUSION: Further studies are recommended to document an epidemiology and bacteriologic analysis of seafood related food poisoning in Chungnam-Taeangun.

OBJECTIVETo establish the indexes and weights of risk assessment of shellfish poisoning outbreak caused by red tide.

METHODSThe risk assessment indexes were developed with the methods of literature review, brainstorm and expert consultation, and the weights of indexes were calculated by the method of analytic hierarchy process. The established indexes contained the risk possibility, impacts of public health, population vulnerability and resilience. The relative risk indexes(integrated risk indexes) of different shellfish poisoning were computed by combining hierarchy process and TOPSIS methods. Moreover, the weights of indexes were further used to generate absolute risk values by multiplying indexes.

RESULTSFour primary indexes and 17 secondary indexes were identified for risk assessment of shellfish poisoning outbreak. Of 17 secondary indexes, the knowing rate of shellfish poisoning, medical accessibility, the number of people being affected, laboratory testing capacity and the habits of eating seafood of local residents had relatively large weights (0.0876, 0.0840, 0.0716, 0.0703 and 0.0644, respectively), which accounted for nearly 38% of the total weight. All consistency ratio (CR) were less than 0.1. The index system was applied in Cangnan county of Zhejiang province. The results showed the relative risk indexes of paralytic shellfish poisoning (PSP), diarrhetic shellfish poisoning (DSP), neurotoxic shellfish poisoning (NSP) and amnesic shellfish poisoning (ASP) were 0.4526, 0.7116, 0.1657 and 0.2884, and the absolute risk values were 0.2542, 0.2668, 0.1907 and 0.2184, respectively. The risk orders of the 4 kinds of shellfish poisoning sorted by relative risk indexes and absolute risk values were consistent.

CONCLUSIONSThe indexes and weights of risk assessment of shellfish poisoning outbreak caused by red tide are established, which can provide scientific advice for prevention and control of shellfish poisoning outbreak.

OBJECTIVES: Heavy metals ingested through the consumption of aquatic products can accumulate in the human body over the long-term and cause various health problems. This study aims to present comprehensive data on the amount of heavy metals found in fish and shellfish in Korea using a systematic review of studies that report on that issue. METHODS: The study used the following databases: PubMed, Korean Studies Information Service System, and Research Information Sharing Service. The search terms for PubMed included fish OR shellfish OR seafood AND mercury OR cadmium OR lead OR heavy metal AND Korea. The search terms for Korean Studies Information Service System and Research Information Sharing Service included eoryu sueun, eoryu kadeumyum, eoryu nab, eoryu jung-geumsog, paeryu sueun, paeryu kadeumyum, paeryu nab, paeryu jung-geumsog, eopaeryu sueun, eopaeryu kadeumyum, eopaeryu nab, and eopaeryu jung-geumsog. RESULTS: A total of 32 articles were selected for review. The total mercury, lead, and cadmium concentrations in fish and shellfish reported in each of the articles are summarized, as are the species of fish and shellfish with relatively high concentrations of heavy metals. Total mercury concentrations tended to be higher in predatory fish species, such as sharks, billfishes, and tuna, while lead and cadmium concentrations tended to be higher in shellfish. CONCLUSION: This paper is the first to report a comprehensive summary of the concentrations of heavy metals in fish and shellfish. This data could be used as evidence to protect Koreans from exposure to heavy metals due to the consumption of highly polluted aquatic products.

BACKGROUND: This study aimed to identify the relationship between exposure to bisphenol A (BPA) and seafood consumption using a nationally representative data of the general Korean population.METHODS: This study was conducted on 5,402 adults aged 19 years and older (2,488 men, 2,914 women) based on the second Korean National Environmental Health Survey (2012–2014). We stratified the data according to gender and analyzed urinary BPA concentrations in terms of sociodemographic characteristics, health behavior, dietary factor, and seafood consumption. In the high and low BPA exposure groups, the odds ratios (ORs) were calculated using logistic regression analysis according to the top 75th percentile concentration.RESULTS: In men, large fish and tuna and other seafood categories had significantly higher ORs before and after adjustment in the group who consumed seafood more than once a week than in the group who rarely consumed seafood, with an adjusted value of 1.97 (95% confidence interval [CI]: 1.12–3.48) and 1.74 (95% CI: 1.10–2.75), respectively. In the shellfish category, the unadjusted OR was 1.61 (95% CI: 1.00–2.59), which was significantly higher in the group who consumed seafood more than once a week than in the group who rarely consumed seafood. However, the OR after adjusting for the variables was not statistically significant. In women, the frequency of seafood consumption and the concentration of urinary BPA were not significantly associated.CONCLUSIONS: BPA concentration was higher in men who frequently consumed large fish and tuna, shellfish and other seafood in this study.

The fact that hazardous metals do not bio-degrade or bio-deteriorate translates to long-lasting environmental effects. In the context of evidently rapid global industrialization, this ought to warrant serious caution, particularly in developing countries. In the Republic of Fiji, a developing country in the South Pacific, several different environmental studies over the past 20 years have shown levels of lead, copper, zinc and iron in sediments of the Suva Harbor to be 6.2, 3.9, 3.3 and 2.1 times more than the accepted background reference levels, respectively. High levels of mercury have also been reported in lagoon shellfish. These data inevitably warrant thorough assessment of the waste practices of industries located upstream from the estuaries, but in addition, an exposure and health impact assessment has never been conducted. Relevant government departments are duty-bound, at least to the general public that reside in and consume seafood from the vicinities of the Suva Harbor, to investigate possible human effects of the elevated hazardous metal concentrations found consistently in 20 years of surface sediment analysis. Furthermore, pollution of the intermediate food web with hazardous metals should be investigated, regardless of whether human effects are eventually confirmed present or not.

To determine blood heavy metal concentrations by seafood consumption in Korean adults, blood cadmium, mercury, and lead concentrations in a representative sample of 1,709 Koreans participated in the Fourth Korea National Health and Nutrition Examination Survey (KHANES IV-2) in 2008 were analyzed by age and seafood consumption frequency. The mean blood cadmium, mercury, and lead concentrations were 1.14 +/- 0.73 microg/L, 5.50 +/- 3.83 microg/L, and 2.56 +/- 1.22 microg/dL, respectively. The subjects aged > or = 50 years had significantly higher blood cadmium concentrations than the subjects aged 20~39 years. Blood mercury concentrations of the 50's were significantly higher than those of the 20's and 30's (p < 0.05). Approximately, 43% of males and 22% of females had blood mercury concentrations > 5.8 microg/L which is a blood mercury level equivalent to the current Reference Dose. Only 2 subjects had lead concentrations > 10 microg/dL, the standard lead level by the Centers for Disease Control and Prevention, USA. The subjects consuming pollack, mackerel, anchovy, corvina, shellfish, and salted seafood at least once a week had significantly higher mercury concentrations than the subjects consuming those seafoods less than once a month. However, there were no clear relationships between blood cadmium and lead concentrations and seafood consumption frequencies.
