In most water disposal, it pay attention to pollution, and color and Ultimate oxygen demand. But, some like Hydrargyrum, Cadmium and other minim-element, because of minuteness content, it has difficulty to inspect. But super-scale minim-element has harm to body's health. In an more and more pollution society, to inspect the minim-element is especially importance.
在处理自来水的过程中,大多只注重了水中的污染物,色度和部分有机物,对于水中含有的各种微量元素,例如:汞,镉,锌等,通常由于其含量微小,而对其进行常规监测有一定的难度,但是微量元素超标对人体健康有着极其的危害,在社会污染日趋严重的今天,对微量元素的监测显得格外重要了。

Methods (1) The device for study was determined by comparing the fluorescent images obtained by laser scanning confocal microscope and CCD fluorescent microscope respectively. The mercury-arc lamp of fluorescent microscope was studied to value its possibility to be used as the irradiation light source. Various image analyzing and processing methods were compared to determine which one was the best to be applied in this study.
(1)实验系统的建立:分别利用激光扫描共聚焦显微镜和CCD荧光显微镜采集ECV 304细胞的DCF荧光图像,并比较两者的成像质量,实验可操作性等技术指标;主要测量输出功率、功率稳定性以及光斑直径这三个指标,考察荧光显微镜的高压汞灯作为本研究中照射光源的可行性;比较并选择合适的荧光图像的分析与处理方法。

Results (1) CCD fluorescent microscope was superior to laser scanning confocal microscope in collecting the fluorescent image of DCF. CCD fluorescent microscope was chosen to be the system applied in this research with the consideration of operation, cost and et al. The mercury-arc lamp of fluorescent microscope was fit for the requirement of our study. The wavelength range of the light output was 460-490 nm and the power density was about 100mW/cm in the condition of our study. Organelle-cell fluorescence intensity ratio analysis was more suitable than other methods.
结果:(1)CCD荧光显微镜采集到的DCF荧光图像的质量优于共聚焦显微镜,同时综合考虑包括采图质量、光照射剂量的可控性、实验成本和操作简便性等诸多因素,最终确定了CCD荧光显微镜作为实验研究的工具;荧光军医进修学院硕士学位论文中文摘要显微镜的汞灯输出功率稳定,光斑均匀,经本实验所选取的光路系统后输出波长范围为460一490nm,功率密度约为1 00 mw/cm;细胞器一细胞荧光强度比值法对于荧光分布位置的确定优于其他方法。

Thesources of self-pollution in agriculture production of Shanghai suburbs are mainlythe agriculture pesticides,chemical fertilizers,urine and excrements of fowls and animalsand the agriculture plastic films at present. Before the seventies,organic mercury pesticides and organic chlorine pesticides wereused in Shanghai suburbs.It influenced the environment greatly. During the eighties,thepesticides making great influence were mainly organic phosphorus and tyiethroids;the fer-tilizer causing great influence ...
上海市郊农业生产中的自身污染,目前主要有农药、化肥、畜禽粪尿和农用塑料薄膜。70年代以前,上海曾施用过有机汞、有机氯等农药,对环境的影响较大。80年代以来,影响较大的农药主要是有机磷和菊酯类;化肥主要是氮肥施用过多,导致蔬菜硝酸盐含量过高;畜禽粪尿已成为郊区突出的新污染源,造成水体的严重污染;各类农用塑料薄膜也是必须重视的新潜在污染物。
