乳浊液膜处理含酚废水

本文报道了一种用于分离废水中苯酚的新液膜体系。该体系是以TBP为流动载体，以LMS-2为表面活性剂组成的煤油液膜，在内外相OH-浓度梯度的推动下．苯酚由外相有效地向内相富集，从而达到分离苯酚的目的。该液膜与其它液膜相比，具有稳定性好，选择性高等优点，用此液膜分离苯酚，除酚率可达99％以上。

昆明盘龙江水质的突变性研究

应用紫露草微核技术对盘龙江水质进行监测，监测结果显示整条江水质呈现出轻重不一的污染段面，北仓、洪家村样点水质具有较高的微核率，微核率分别为６．８５％，７．５０％，城区河段致紫露草微核的潜在性污染物较轻，最低点为油管桥样点，微核率为４．３５％，但从整体来看，由松花坝微核率３．２０％至滇池的附近洪家村增至７．５％，水体的潜在性致突变物污染程度逐渐加重。这表明盘龙江水体可能存在致突变的危险性。

硼污染的个人暴露剂量及其代谢的研究

 以62名处于不同生活、工作环境下的人群为对象,研究了其通过空气粉尘、饭菜和饮水的日硼暴露剂量及通过尿液、粪便的代谢状况.结果表明,从事硼作业的53名工人日硼暴露均值11.8mg/d,是对照人群(1.52mg/d)的7.8倍;通过尿液代谢的硼占总代谢量的94%以上,且班后尿硼与24h全尿硼浓度的相关系数为0.952,班后尿样可代替全尿并反映硼的代谢水平;下班后尿硼浓度与日硼暴露剂量显著相关.多元线性回归可以反映不同暴露途径对尿硼水平的贡献,方程拟合度为43.0%,与实测值的平均相对偏差为23.6%.     

GC-MS法测定植物排放的萜烯类化合物

采用流动式采样与气相色谱-质谱联用法研究了意大利撒丁岛Noak’s Ark自然生态区四种主要灌木树种Juniperus phoenicea(腓尼基桧)，Pistacia lentiscus(黄连木)，Phillyrea angustifilia，Chamaerops humilis(欧洲矮棕)的排放速率和排放特征。结果表明，JuniPerus phoenicea(腓尼基桧)，Pistacia lentiscus(黄连本)，Phillyrea angustifilia主要排放萜烯类化合物，其中包括α-蒎烯、β-蒎烯、苎烯、戊花烃、莰烯、β-水芹烯、桧烯、β-香叶烯和3-蒈烯等；Chamaerops humilis(欧洲矮棕)主要排放异戊二烯。在标准条件下(温度30℃，PAR为1000μmo1．m^-2．s^-1)，四种树种的排放速率分别为0.15、2．10、0．20和1．87μg／g(DW)．h。     

Ultrasound evaluation of pregnancies at risk for homozygous α-thalassaemia-1

Twenty-six pregnant Chinese women who were at risk of giving birth to a fetus affected with homozygous α-thalassaemia-1 were examined serially by ultrasound. Six of these 26 pregnancies were affected. In one third of the affected pregnancies progressive fetal ascites appeared before 24 weeks gestation and these pregnancies were terminated. In the remaining two thirds abnormal estimated fetal weight-placental volume (EFW-PV) ratio and fetal growth retardation as evidenced by a falling biparietal diameter (BPD), femur length (FL) but a normal abdominal circumference (AC) was apparent by 28 weeks gestation. Increased transverse cardiac (TC) diameter was another consistent finding but appeared late. All these features appeared before the onset of fetal ascites. A normal EFW-PV ratio and fetal growth until 28 weeks gestation was a reassuring sign of normality. Abnormal EFW-PV ratio was the earliest sign to appear in affected pregnancies and a normal ratio until 28 weeks gestation had a 100 per cent predictive value.

Effect of TiO2 surface properties on the SCR activity of NOx emission abatement catalyst

NOx emission abatement catalysts V2O5 supported on various TiO2 including anatase, rutile and mixture of both were investigated with various physico-chemical measurements such as BET, NH3-TPD, NARP, XRD and so on, and the effect of TiO2 surface properties on the SCR (selective catalytic reduction) activity of V20s/TiO2 catalysts was studied. It was found that the TiO2 surface properties had strong affect on the SCR activity of V2Os/TiO2 catalysts. The stronger acidic property resulted in the higher exposure of active sites as well as the higher SCR activity.
