The purpose of this study is to detect metabolic syndrome components related to exposure of organic solventthrough comparison and analysis of metabolic syndrome components between workers at the workplace exposedto organic solvent (toluene, xylene, styrene) and workers at general workplace. During the period from Januaryto December 2010, the survey was conducted against male workers of 168,769 persons with age group 30-59completed medical checkup, dividing workers at organic solvent exposed work place and workers of generalworkplace against which comparisons were carried out about the result of general characteristics, blood test.Whether exposed to organic solvent and exposed period relationship with metabolic syndrome components wereidentified through execution of multiple logistic regression analysis. The prevalence rate of the metabolic syndromeby age was 15.0% for the 30s, 19.8% for the 40s, 22.9% for the 50s. For the whole workers, the prevalence rateof the metabolic syndrome was 17.4% in exposed workplace and 18.4% in general workplace that was higherthan the rate in exposed workplace. Even if age, drinking, smoking, exercise, region and BMI were corrected,the exposure to the organic solvent was the higher the significance of blood pressure and fasting glucose werestatistically and also the longer the period of exposure was, the higher the significance of blood pressure wasstatistically. In this study, the exposure to the organic solvent showed a statistically significant relevance with bloodpressure and fasting glucose among the metabolic syndrome components and the period of exposure showed astatistically significant relevance with blood pressure. Further researches should be conducted by prospective cohortstudy about the organic solvent and the metabolic syndrome components supplementing the defects.

The aim of this study was to determine exposure assessment of pathogenic bacteria in edible ices by using the monitoring data from the previous study. According to the results of exposure assessment of edible ices contaminated with S. aureus, the contamination level of S. aureus in raw materials was higher than other foodborne pathogens, and the contamination level of S. aureus in mixed samples increased much before sterilization. The most significant reduction in contamination level was observed in mixed samples after sterilization, thus, the contamination levels in frozen final products was less than that of raw materials. Overall, the possibility for the infection of foodborne bacteria from the intake of edible ices per person per day was ranged from minimum 5.89 × 10-7 to maximum 5.01 × 10-5. For more realistic estimates, consumption of edible ices and dose-response model must be studied further.
