한강수를 수원(水源)으로 하는 수도수의 Trihalomethane 의 정량
손동헌,조경열,김귀자 한국물환경학회 1987 한국물환경학회지 Vol.3 No.1
서울시의 팔당 구의 뚝도 보광동 및 노량진의 수원지의 수도구를 거리별로 17지점을 선정하여 1984년 7월, 8월, 9월, 月 1回씩 수도수 中의 trihalomethane量을 head space法으로 정량한 결과 다음과 같은 결과를 얻었다. 1. 서울시 수도수 中의 total trihalomethane量은 7월, 8월, 9월의 평균값이 각각 32.2, 19.1, 9.8㎍/ℓ이였다. 8월 9월의 trihalomethane量과 비교하면 7월이 현저하게 높았다. 2. 水源池別 total trihalomethane 量은 뚝도 노량진 水源池계통의 수도수가 비교적 높은 값을 나타내었다. 3. 七月의 노량진 水源地의 水道水中의 CHCℓ₂Br의 平均값은 12.9㎍/ℓ로서 전체平均값 6.5㎍/ℓ의 2倍를 나타내고 있었다. From 17 tap water sampling points throughout the metropolitan Seoul supplied from paldang, Gueui, Bokwang, Noryang jin and Dukdo water treatment plant, using Han river as water source, trihalomethane concentration were measured 3 times during July, August, and September, 1984. Total trihalomethane were high in tap water samples from Noryang jin and Dukdo water treatment plant and low from Gueui water treatment plant. Average trihalomethane concentrations were 32.2㎍/ℓ, 19.1㎍/ℓand 9.8㎍/ℓfor July, August, and September respectively, and by comparing with the trihalomethane concentrations of August and September, that of July was obviously high. It is noted that average CHCl₂Br concentration of tap water supplied from Noryang jin water treatment plant in July was 12.9 ㎍/ℓ which were attained to about twice of total average concentration of 6.5㎍/ℓ.

To survey the background values and conditions of pollution originated from mercury compounds, water and fish samples were collected in 12 places of Keum river basin from August to September in 1989 and their total mercury contents were analyzed. Physico-chemical properties of water were determined at collection. The mercury in water sample was extracted with dithizone-benzene and fish samples were pretreated for direct combustion. Total mercury contents were detected by Quartz Tube Combustion-Gold Amalgamation Method using Flameless Atomic Absorption Spectrophoto-mery. Calibration curves were constructed by injection of standard solution for fish and standard addition method for water. Total mercury content of 10 species, 90 fish samples were averaged 0.126ppm and that of water was 0.188ppb. The fluctuation of the total mercury contents, their biologi-cal concentration ratios and physico-chemical properties of water would be discussed in this paper.

Environmental concerns are focussed on the soil and groundwater pollution by harzadous heavy metals which are exhausted from industries. Recently, the studies on the cereal pollution have been increasingly reported and especially, the pollution of rice on which most oriental people are subsisting is very important in environmental hygiene. In this study, the author investigated the contents of harzadous heavy metals (Zn, Cd, Pb, Mn, Cu, Ni, Co, Fe) and alkaline metals (Ca, Mg) in unpolished rice collected from nationwide of korea. The 97 samples of unpolished and polished rice were collected in fall, 1973, to be digested by plasma ashing device. Atomic absorption spectroscopy equipped with multiwavelength hollw cathode lamp was used to determine the analytes. The mean contents of heavy and alkaline metals in rice samples of korea were as follows; 15.96 ppm for Zn, 0.097 ppm for Cd, 0.43 ppm for Pb, 27.57 ppm for Mn, 2.61 ppm for Cu, 0.31 ppm for Ni, 0.13 ppm for Co, 10.75 ppm for Fe, 31.22 ppm for Ca, 870 ppm for Mg and 0.0193 ppm for Hg. Their distribution and comparison of existing levels with other reports are also described.

우리가 향유하고 있는 문명의 이기는 거의 기초과학의 산물인데도 우리나라 기초과학연구비는 전체 연구비의 15% 정도로 푸대접을 받고 있어 이 분야의 과감한 투자가 아쉽다. 또한 선진국의 교육제도를 과감하게 수용해서라도 21세기를 이끌어갈 엘리트를 길러내는 일도 시급하며 산업화사회를 지향하다가 자멸할지도 모를 우리 주변환경을 보존하기 위해서는 첨단과학의 헌신도 있어야 할 것이다.
