Prenatal diagnosis of mosaic 4p – in a fetus with trisomy 21

Mosaicism for the Wolf-Hirschhorn syndrome, del(4)(p16), is extremely rare and has not been reported in association with a numerical chromosome abnormality. We report the prenatal diagnosis of mosaic del(4)(p16) and non-mosaic trisomy 21 in a 16-week female fetus. The pregnancy ended in spontaneous abortion at 34 weeks secondary to fetal demise. The fetus had features of both 4p – and trisomy 21.

战略环境评价及其应用初探

概述了战略环境价的概念、产生原因、研究现状及其工作程序，结合川南矿肥工程项目对它进行了应用初探，提出了计划、规划层次ＳＥＡ的方法和指标，并对我国环评工作提出了建议。     

沉淀物和生物中U,Th和226Ra的联合测定

用放射化学法对U,Th,~(226)Ra等核素进行联合测定,国外已有不少报道,只是所用的分离方法和所测的介质不同而已。我国学者也做过一些这方面的工作。本工作建立了用三正辛胺-二甲苯萃取分离法对沉积物和生物样中U,Th和~(226)Ra的联合测定方法。 二、主要仪器与试剂     

戴明循环理论在规划环评工作程序中的应用初探

通过分析现阶段我国规划环评的现状和存在的问题,结合国内外规划环评及其工作程序的研究成果,提出使用戴明循环理论对现阶段的规划环评工作程序进行改进,使程序层次化、工作细分化,增强整个规划环评工作的可操作性,使规划环评工作落实到单位和人,明确责任,减少部门间冲突.戴明循环理论的引入,提高规划环评的评价效果和效率,为规划环评提供了一个有效科学的评价方法,有助于规划环评的顺利开展,使环境问题从源头上得到控制,适应建设和谐社会的需要.     

Toxic effects of wastewater from various phases of monosodium glutamate production on seed germination and root elongation of crops

To make a comprehensive assessment on monosodium glutamate (MSG) wastewater pollution, a pollution exposure experiment was carried out on the seed germination and root elongation of wheat, Chinese cabbage and tomato by using the wastewater discharged from different processing phases of MSG production. The results showed that there were significantly positive linear relationships between the inhibitory rates of wheat seed germination and root elongation and the COD_cr of the mother liquor scraps. The toxicity of MSG wastewater to the test crops was in the order of tomato > Chinese cabbage > wheat, indicating that tomato was the most sensitive to the wastewater, and could be considered as an ideal toxic bioindicator. The half-effect concentrations (IC₅₀) based on the seed germination and root elongation of the test crops exposed to the wastewater discharged from various processing phases of MSG production was 22.0–32 432 and 17.3–3320 mg/L, respectively.

生物砂滤池对有机物和氨氮的去除

当在常规工艺前加生物预处理并取消预加氯时,砂滤池就成为生物砂滤池。与普通砂滤池相比其对有机物、氨氮和浊度的去除率都有很大的提高。实验以珠江源水为水源研究了生物砂滤池对高锰酸盐指数、NH3-N、NO2--N和浊度的去除,在实验期间生物砂滤池出水高锰酸盐指数、NH3-N、浊度平均值分别为1.32mg/L、0.098mg/L、0.171NTU,其相对于沉淀池出水的高锰酸盐指数、NH3-N、浊度的平均去除率分别为18.52%、72.93%、64.45%,而砂滤池出水NO2--N几乎检测不出来。滤池进水与出水溶解氧的变化也证明了砂滤池中生物的存在,并且生长状况良好。
