대구시 인근에 산재한 약수에 대한 위생학적 조사(1986)
차상덕,장봉기,천병열,김두희,Cha, Sang-Duk,Chang, Bong-Ki,Chun, Byung-Yeol,Kim, Doo-Hie 대한예방의학회 1986 예방의학회지 Vol.19 No.2
최근 질병의 치료 및 건강증진을 목적으로 많은 사람들이 약수를 마시고 있어서 이에대한 위생학적검사가 중요한 관심이 되고있다. 대구직할시와 인근한 11개 약수터를 대상으로 1986년 3월 27일부터 4월 17일까지 약수터의 위생시설상태을 알아보고 약수를 채취하여 생물학적 및 이화학적 검사를 실시하였다. 주변위생시설이 제대로 된 곳은 11개 약수터 중 3개소로 27.3%에 불과하였으며 생물학적검사 중 대장균이 음성인 곳은 1군데 뿐이었다. 이화학적 성분검사결과 음료수 수질기준을 초과하지 않은 지역은 3개소 이었으며 특히 '가창약수' '영천약수' '달기약수'는 중금속 농도가 음료수 허용기준치를 초과하고 심한 산성이었다. 이상의 결과로 볼 때 세균 및 이화학적 성분 조사에서 전체 11개 대상 약수에서 우리나라 음료수 수질기준에 비추어 볼 때 부적합한 결과로 나타났으며 가장 부적합한 항목이 많은 곳은 가창 황물과 영천 황수였다. 이에 대한 대책으로서 약수터 주위의 위생시설의 미비점 보완 및 약수터의 위생적인 관리가 필요하며 중금속 농도가 높은곳은 오염원을 찾아 제거시켜야할 것이다. 'Medicinal water' have been used for the treatment of disease and the promotion of health. To study the quality and health effect of 'medicinal water', the eleven springs located near Taegu City during the period of March 27-February 17, 1986 were tested for biological and physiochemical examination and were checked for sanitary environment around the spring. Among them three springs (27.3%) had a good sanitary equipments and only one was negative for biological examination. Three 'medicinal warer' were accepted as potable by physicochemical examination. According to above findings, all of the 'medicinal water' sampled from the springs located near Taegu City were not potable by this sanitary survey adopted Drinking Water Standard in Korea. Kachang and Youngchum 'medicinal water' were more contaminated by heavy metals and bacteria than those of other springs. To solve the problem of contamination by heavy metals that originated from uncertain sources, we should search for the sources of water contamination, remove it completely and also support the environmental equipments and management system in protection of safe 'medicinal water' supply.
SPE/GC/MS 를 이용한 Phthalate Ester 의 동시 분석
양승태(Seung Tae Yang),정상섭(Sang Sub Jung),차상덕(Sang Duk Cha) 한국물환경학회 1999 한국물환경학회지 Vol.15 No.1
A method for determining six phthalate esters by using SPE(solid phase extraction) and GC/MS is descrived. The SPE was performed with C_(18)-bonded silica in 6㎖ Supelclean LC-18 cartridge of Supelco. The optimal pH, volume and flow rate of sample through SPE cartridge were neutrality, 500㎖ and 8.3㎖/min, respectively. The GC analysis was performed with SPB-5 capillary column(30m × 0.25㎜ I.D. × 0.25 film thickness) with He as carrier gas operated with temperature programming from 100℃ (held for 1min) to 260℃ (held for l0min) at 10℃/min, and the detection was by MS-SIM in EI^+ ionization mode at m/z 40∼500. Average extraction recovery(%) was 79.6% for a 500㎖ volume of water spiked at 5㎍/ℓ. Each calibration curve on six phthalate esters was linear for 0.1∼25㎍/ℓ and method detection limit(MDL) was 0.06㎍/ℓ. The SPE was compared with LLE(liquid liquid extraction) in the extraction recovery(%). The procedure could be used for examinating effect of sample matrix on extraction recovery(%) and determining phthalate esters in the river.

Progressive muscular dystrophy is a primary degenerative disease of skeletal muscles without evidence of regeneration. This group of diseases is characterized by symmetric distribution of muscular atrophy, intact sensation and reflexes, and a heredofamilial incidence. Etiology is unknown but is generally accepted as hereditary. Boys are attacked much more frequently than girls and it is now recognized as an sex-linked recessive disease. Usually the first symptom to attentation is insecurity in standing or in walking. Diagnosis is confirmed by measurement of serum enzymes, by electromyography and by muscle biopsy. Diagnosis can be established at birth by measurement of CPK level. There is no effective treatment and the children should be kept active and in as ambulatory state as long as possible. This paper presents two cases of progressive muscular dystrophy (Duchenne type) which occurred in brothers and literatures were reviewed briefly.
