云南小水泥粉尘污染及治理探讨

进入九十年代后，由于盲目上马，布局失控，云南省小水泥迅速发展。落后的工艺技术和管理使水泥粉尘排放量剧增，对大气造成了严重污染。应积极推进小水泥结构调整，加强管理，综合治理，才能减少粉尘排放量，改善大气环境质量     

生物处理港口含油污水

着重讨论两种生物处理工艺对港口含油污水的处理效果，试验结果表明；经ＰＡＣ絮凝──生物接触氧化工艺处理，出水ＣＯＤ＜１００ｍｇ／Ｌ，达到排放标准。     

碱性条件下化学法处理大同齿轮厂混合电镀废水

针对大同齿轮厂电镀车间外排废水中既含CN- 离子 ,又含Cr6+及Ni2 +、Zn2 +、Cu2 +等重金属离子的现状 ,在碱性条件下 ,采用先氧化破氰 ,再还原六价铬至三价铬 ,最后混凝沉淀的处理工艺 ,使处理后出水达标排放     

A 1 and 6 month follow-up of prenatal diagnosis patients who lost pregnancies

This paper reports results of an exploratory study of prenatal diagnosis patients who experienced voluntary terminations of pregnancy following the detection of an abnormality or spontaneous miscarriages. The 121 participants were part of the national collaborative Chorionic Villus Sampling and Amniocentesis Study. They completed semi-structured telephone interviews and mailed questionnaires at 1 month and 6 months after the pregnancy losses. Scores on the Profile of Mood States showed that mood levels improved significantly over time. However, there were some declines in loss-related support from partners and others. The persisting distress and difficulties of a minority highlight the variability in women's responses to pregnancy losses. Women who lost pregnancies later in gestation, showed the greatest mood disturbances at initial assessments, used professional mental health assistance after the loss, or reported less satisfactory loss-related support from significant others showed the greatest levels of mood disturbance at the six-month assessment. Follow-up contacts with patients who lose pregnancies should be used to inform women about the variation in possible grief reactions, to assess the extent of support the women are receiving from their partners and significant others, and to provide additional follow-up or referral of those experiencing the greatest distress.
