Behaivior of some metal complexans in pollutedwater and its control.

表面活性剂是一种配伍性好的络合剂，广泛应用于各种工业领域。人造络合剂的使用范围很广，包括乳化、家用洗涤、机洗和化肥。洗涤剂的消耗量逐年增加。它们对水质、农产品、鱼类、贝类、水生植物等都有影响。(1)24小时人类活动中洗涤时间的影响证实了城市河流水体中金属络合物浓度和分布在一天内的变化。此外，阴离子表面活性剂的浓度与工厂的工作时间或不工作时间有相关性。(2)水生植物体系中金属络合物、阴离子表面活性剂对植物金属积累的影响。表面活性剂的积累量取决于暴露浓度和暴露时间。十二烷基硫酸钠、十二烷基硫酸钠、十二烷根组织对十二烷基硫酸钠的敏感性高于茎。(3)磁力微能降低微能对日本国内产生饮用水霉味、有机物污染的绿藻生长的抑制作用。(4)研究了铁形态对四种蓝藻生长的影响。在不含EDTA的CT培养液中，由于不能利用胶体铁和铁氧化物生长，几乎被认为是蓝藻。这些结果表明，某些络合物对水生植物和水生动物的生长和积累有一定的影响。

The surfactans are complexing agents with high compatibility used in many kinds of industries. The range of used of man-made complexing agents is very wide and includes emulsigying, domestic washing, machine washing, and fertilizer. The comsummption volumes of detergents keeep on increasing year by year. They affected water quality, agricultural products, fish, shellfish, and water plants etc. This research was mainly composed next of three subject. (1) Change in concentration and distribution of metal complexan in city river waters affecting domestic area through a day was confirmed by the effect of wasshing time in the 24 hours human activity. Also, the concentration of anionic surface active agents was coresponding with or without working time of factory. (2) Effect of metal complexan, anionic surface-active agents on the metal accumulation of plant in water-plant system. The amount of accumulation of surface-active agents was depend on the exposure concentration and exposure time in weater. Also, the order of cencentration of sodium lauryl sulfate, SDS was root>stem of plant exposered with SDS containing water. The root tissue was more sensitivity to SDS comparedwith that of stem of plant. (3) Effect of micro-energy with magnetic power on the decreasing of micro-energy with magnetic power on the decreasing of growth of geen algae which produce the some kind of musty odor of drinking water, organic substances polution in domestic area in Japan. (4) The effecs of iron forms on the growth of four cyanobacteria were studied. Almost cyanobacteria was supposseds in the EDTA free CT medium because of no ability to utilize colloidal iron and iron oxides for its growth. These results suggested that some kinds of complexans affected to aquatic plants and aquatic animals for the growth and its accumulation.
