This survey study was performed to evaluate the pollution level of playgrounds for children at 49 different sampling sites in Seoul metropolitan. Results were as follows. 1. Soil pH ranged from 6.0 to 9.2. 2. Average concentrations of heavy metals were 0.101 mg/kg of Cd, 4.470 mg/kg of Cu, 0.10 mg/kg of As, 5.35 mg/kg of Pb, 0.017 mg/kg of $Cr^{6+}$ 0.0051 mg/kg of Hg, which were lower than Korean soil precaution level. 3. The SPCs of all areas were below 100, which is 1st grade. In conclusion, the pollution level of playgrounds for children was safe.

Botulism in wild waterfowl has been reported in many areas of the world. In 18 October 2008 to 22, 101 dead wild ducks were found in Anyangcheon. 24 of dead birds were spotbill (Anas poeilorhyncha), 56 were Mallard (Anas platyrhynchos), 18 were green- winged teal (Anas carolinensis) and 3 were others. Clinical sign of the sick birds were flaccid paralysis of the neck. At autopsy, most birds had no specific lesions. Stomach is empty. In the mouse bioassay, Samples of serum and intestinal contents taken from 9 dead birds killed all the injected mice, and their toxicity was neutralized by the antitoxin against C. botulinum type C toxin.

The antimicrobial susceptibility of 73 strains of Staphylococcus aureus isolated from dogs and cats was determined against 16 antimicrobial agents. All isolates were susceptible to cephalothin (CF), vancomycin (VA), rifampin (RA), quinupristin-dalfopristin (SYN) and linezolid (LZD), whereas more than 86.3% of the isolates were resistant to penicillin (P). In the case of enterotoxin production, 8.2% of 73 strains produced enterotoxin A and 1 strain produced enterotoxin C. Appropriate protocols for antimicrobial agents and strategies to reduce antimicrobial resistance will need to be investigated in the future.

We investigated the residues of 6 cephalosporins (cefquinome, cephalexin, cephalonium, cefazolin, ceftiofur, cefuroxime) using LC-MS/MS in raw meat in Seoul. This method involves extraction of the residue from the meat by distilled water and methanol followed by a manual of residue analysis published by the National Institute of Food and Drug Safety Evaluation. The recoveries ranged between 74.71~90.01% in beef, 73.37~101.40% in pork and 70.87~95.53% in chicken, respectively. The limits of detection were 0.0004~0.0563 mg/kg, and the limits of quantification were 0.001~0.169 mg/kg respectively. Residues of cephalosporins which exceeded maximum residue limits (MRL) were not exceed in any of the 287 samples. However, it is necessary to develop multi-method, which includes the active metabolites of ceftiofur.

This study was carried out to investigate the content of sulfur dioxide residues in the medicine prepared from crue drugs. Total 29 pills that contains salvia miltiorrhiza root, anemarrhena rhizome, fritillaria bulb, glehnia root, asparagus tuber, lycium fruit, moutan root bark, cimicifuga rhizome, pinellia tuber, dipsaci radix, codonopsis pilosula root, liriope tuber, achyranthes root, prepared aconite, aurantii fructus immaturus, corydalis tuber, dioscorea rhizome were examined by the modified Monier_Willams method. Sulfur dioxide were detectd in all the tested samples, and were found over MRLs (30 mg/ kg to medicinal herbs) in 8 samples (27.6%). Especilly, "i2" pills contains 132.46 mg/kg sulfur dioxide that is 4 times over than MRLs.

To analyze the clinical and endoscopic features of colonic anisakiasis. A retrospective chart review of 20 patients with colonic anisakiasis, who were diagnosed by colonoscopy at 8 hospitals between January 2002 and December 2011, was performed. Patients' mean age was $53.6{\pm}10.74years$. Seventy percent patients were men. Acute abdominal pain was a common symptom that mostly developed within 48 hr after the ingestion of raw fish, and which lasted for 1-28 days. Sixty percent patients had ingested raw fish before the diagnosis of colonic anisakiasis and 40% patients were incidentally found to have colonic anisakiasis during the screening colonoscopies. Leukocytosis and eosinophilia were each found in 20% of the patients. In all patients who underwent colonoscopy, the worms were removed with biopsy forceps, except in 1 case, and a definite diagnosis of anisakiasis was made. In some cases of colonic anisakiasis, colonoscopy may be helpful in the diagnosis and treatment to avoid surgical intervention.

2008년 국민건강영양조사에서 서울시민의 연령별 채소섭취량을 산정하여 2007년부터 2009년까지 서울지역에서 유통 중인 채소류에 대한 잔류 농약을 모니터링 하여 채소류섭취에 따른 연령별 농약성분의 노출량을 평가하였다. 서울시민에 대해 연령별 평균 채소류 섭취량을 분석한 결과 통계적으로 유의한 차이가 있었다(p<0.001). 연령그룹 중 40~59세 그룹의 채소류 섭취량이 가장 높게 나타났고 5세 이하 그룹의 채소류 섭취량이 가장 낮게 나타났다. 2007년부터 2009년까지 채소류 섭취에 따른 연령별 잔류농약의 %ADI(Acceptable Daily Intake)는 모두 1 이하로 나타나 잔류농약으로 인한 위해 가능성은 낮을 것으로 판단된다.

본 연구에서는 에폭시 수지 갱생 옥내급수관 수돗물에 대해 비스페놀-A 실태조사를 실시하였고, 비스페놀-A가 수돗물 음용에 있어 인체에 미치는 영향을 파악하기 위해 위해성 평가를 실시하였다. 원수 중 비스페놀-A는 50~118 ng/L로 채취된 모든 시료에서 정량한계 10 ng/L 이상으로 검출되었다. 이것은 주변지역의 하수 방류수나 지천에 의한 비스페놀-A 유입에 의한 것으로 판단된다. 정수에서의 비스페놀-A는 불검출되었으며, 고도정수처리 공정에서 모두 제거된 것으로 추정되었다. 응집-침전과정과 오존 및 염소에 의해 산화되어 제거되거나 다른 산화 부산물질로 변화한 것으로 판단된다. 옥내급수관 수돗물의 경우, 에폭시 갱생공사를 실시하지 않은 수돗물 모두에서 비스페놀-A는 검출되지 않았다. 그러나 에폭시 갱생공사를 실시한 옥내급수관 수돗물에서 비스페놀-A가 불검출에서 최대 521 ng/L로 범위로 검출되었으며, 채취된 시료의 68%가 정량한계 이상으로 검출되었다. 검출된 비스페놀-A의 최대값(521 ng/L)에 대한 위해도 지수 산정 결과, 위해도 지수(HQ)는 약 0.004로 수돗물 섭취에 의한 위해판단 기준값 0.1 이하로 나타나 음용에 안전한 것을 확인하였다.

We investigated springs in Seoul in 2009 to know the change of water quality according to storage method of spring water, the concentration of chemical compounds and their correlation. Even spring water that originally satisfied national standard for drinking water could be exceeded national standard for drinking water by storage method such as storage bottle, temperature and period; especially used PET bottles could affect the increase of total colony counts. Therefore, spring water is desirable to be consumed on the spot, or to be stored in sterilized bottles in refrigerator rather than room temperature at home, and also to be consumed shortly not exceeding 24 hours. Total colony counts, coliform, yersinia, $F^-$, $Cl^-$, $NO_3^--N$, hardness, total Solids, pH, color and Al were exceeded national standard for drinking water at some springs. The result of correlation analysis shows that hardness and total solids, which are caused by several ionic compounds, had relatively high correlations with other chemical compounds.

본 연구에서는 식품에서의 L. monocytogenes에 대한 기초자료를 제공하고자 2010년부터 2011년까지 서울지역에서 수거된 식품 총 1042건에서 L. monocytogenes를 분리하여 항생제 감수성 검사를 하였다. 김밥 4건(0.8%), 육회 4건(2.6%), 연어제품 2건(11.1%), 돈육식품과 조리된 생선에서 각 1건씩(각5.9%, 6.3%) 총 12균주가 분리 동정되었다. 분리 균주를 20종의 항생제에 검사한 결과 대다수 항생제(16종)에 감수성을 나타내었지만 cefotetan (11균주), cefotaxime (7균주), cefepime (6균주)에서 내성을 나타냈으며 3균주에서 임상치료에 자주 사용되는 tetracycline에 대해서 내성을 나타내었다.
