• 中文摘要： 在實驗室中，以培養液培養銅誘微囊藻，觀察在不同培養時間或不同生長時期，培養液中所產生之總有機碳及過濾培養液之溶解性有機碳增加情形，並於培養液及過濾培養液加氯後分別檢驗其三鹵甲烷生成潛能及可吸附性有機鹵生成潛能。對於溶解性有機碳，以膠體層析法依分子量分為四個族群，以瞭解溶解性有機碳在不同生長時期增加情形。實驗結果顯示，培養液中之諸參數，如總有機碳、溶解性有機碳、三鹵甲烷生成潛能、可吸附性有機鹵生成潛能等，均隨培養時間增加而增加，在死亡期之生產尤劇。四個不同分子量族群之溶解性有機碳亦隨培養時閒增加而增加，而在死亡期最低分子量者(G IV)有顯著增加，其次為最高分子量者(G I)。
• 英文摘要： The objective of this research was to examine the production of TOC (Total Organic Carbon) andDOC (Dissolved Organic Carbon) in culture medium, which resulted from the growth of Microcystisaeruginosa under different cultivation times or growth phases. Furthermore, the formation of THMFP,AOXFP and THM FP, AOX FP is discussed during chlorination experiments, conducted using unfilteredculture solutions (for THMFP, AOXFP) and filtered culture solutions (for THM FP, AOX FP) is discussed.DOC was divided into four groups, according to molecular weight distribution, which was determinedby gel chromatography, in order to study the variation of the DOC of the different molecular weight groups. The results showed that all of the parameters, such as TOC, DOC; THMFP, THM FP, AOXFP, andAOX FP, increased with cultivation time, especially in the death phase, indicating that the growth ofMicrocystis aeruginosa had an adverse effect on water quality. The DOC of the four different molecularweight groups accumulated with cultivation time. Especially in the death phase, the most significantaccumulation was in the group with the lowest molecular weight (G IV) and that in the group with thehighest molecular weight (G 1) was next.
