So, a lot of fundamental research work needed to be done, including screening Daphnia, as a biomonitor, that is sensitive to toxicant but less to environment changing so as to decrease the environmental interferences for obtaining more accurate determination results; exploring the relationship between the phototactic behavior of Daphnia and pollutants such as nitrogen, phosphate, heavy metal, hormone and pesticide, especially their mixtures; studying the effect of environmental conditions such as temperature, pH and fish kairomones on the phototactic behavior of Daphnia.

口。。。口国。国里华典翩胭角嗓国但由于缺乏有效的研究方法，致使有关研究难于开展，人们不得不忽略有害物质之间的互相作用，把有害物质共同存在情况视为单一存在。因此，研究氮、磷和重金属对水搔趋光行为的影响规律，有益于认识富营养化水体和重金属污染的土壤中污染物之间的相互作用，弄清这些污染元素共存时产生的生物和环境效应，这些研究是治理土壤和水体污染之前必须解决的重大科学问题。

Results showed that there were significantly positive linear correlations between the toxic effects（probits of mortality and inhibition rate） of chlorpromazine on the two aquatic organisms and the concentrations of chlorpromazine, and the toxic intensity became higher as the exposure time increased. The LC50 values of chlorpromazine acting on Carassius auratus in 24, 48 and 96h were 1.11, 0.43 and 0.32mg·L-1, respectively; and its safe concentration for Carassius auratus was 19.5μg·L-1. The LC50 and EC50 （50% of the tested Daphnia magna inhibited） values of chlorpromazine acting on Daphnia magna in 24h were 0.65 and 0.57mg·L-1, and the LC50 and EC50 values in 48h were 0.36 and 0.28mg·L-1, respectively. Thus, chlorpromazine have high toxicity to Carassius auratus and Daphnia magna, and the latter is more sensitive to chlorpromazine.

结果表明：氯丙嗪对两种水生生物的毒性效应（致死率、抑制率概率单位）均与其浓度呈显著线性正相关关系（p.05），且毒性强度随作用时间的延长而增加；氯丙嗪对鲫鱼的24、48和96h的半致死浓度（LC50）值分别为1.11、0.43和0.32mg·L-1，通过计算求得氯丙嗪对鲫鱼的安全浓度为19.5μg·L-1；氯丙嗪对大型蚤的24h LC50值为0.65mg·L-1，24h EC50值（使50%受试大型蚤活动受抑浓度）为0.57mg·L-1；48h LC50值为0.36mg·L-1， 48h EC50值为0.28mg·L-1；对鲫鱼和大型蚤而言，氯丙嗪属极高毒性物质，大型蚤对氯丙嗪的敏感性大于鲫鱼。
