We performed chromosomal aberration assay in Chinese Hamster Lung (CHL) cells in vitro to evaluate theclastogenicity of 11 synthetic chemicals which were listed in Toxicity Evaluation Program of Ministry of Environment of Republic of Korea in 1996. All of the chemicals were carried out MTT assay to determine the 50% cell growth inhibition concentration. All compounds were tested with and without metabolic activation system. Benzoyl chloride revealed positive result at $43\;\mu\textrm{g}/m{\ell}$ in the presence of metabolic activation system, and at 30.8, 61.5 and $123\;\mu\textrm{g}/m{\ell}$ in the absence of metabolic activation system. And p-phenoxy ethanol was observed as positive with the metabolic activation system, but negative without metabolic activation system. Especially 2-propyn-l-ol showed high frequency of pulverization and showed critical difference of cytotoxicity between with and without S9 mixture. Pulverizatiuon is not included in the frequency of structural aberration in our criteria. Dicyclopentadiene, methacrylic acid, aa-dimethylbenzyl hydroperoxide, benzylbutyl phthalate, and p-chlorophenal were revealed negative results.esults.

상업적으로 이용되는 폴리스티렌계 이온교환막은 제조 공정이 쉽고 간단하지만 막이 가지는 취성 때문에 내구성이 약하다는 단점을 가지고 있다. 이를 보완하기 위하여 친수성 그룹인 poly(ethylene glycol)을 곁사슬로 가지고 있는 poly(ethylene glycol)methyl ether methacrylate를 공중합시켜 음이온 교환막을 합성하였다. 지지체로는 내화학성 및 기계적 강도가 우수한 다공성 PE 지지체를 사용하였고, 여기에 다양한 조성의 vinylbenzyl chloride, styrene, poly(ethylene glycol)methyl ether methacrylate, divinylbenzene, benzoyl peroxide를 녹인 단량체 용액을 지지체 기공에 채운 뒤 열중합 가교시켜 trimethylamine을 이용하여 음이온 교환기를 도입해 세공충전 음이온 교환막을 합성하였다. 또한 poly(ethylene glycol)methyl ether methacrylate의 곁사슬 길이와 각 단량체가 차지하는 비율의 변화가 음이온 교환막의 전기화학적 특성에 미치는 영향을 알아보았다.
