厦门西港海水质量对鱼卵胚胎发育畸形率的影响

以养殖场培育的花尾胡椒鲷受精卵为实验材料测试了厦门西域5个站位的表层水水样对花尾胡椒鲷受精卵的胚胎发育毒性，并运用GC－MS手段分析了水样中的美国EPA优控的16PAHs组分的含量。结果表明：3号站位（厦门市工业和生活污水主要排放口的外侧）和4号站位（厦门西港的港区）的水样对鱼卵的胚胎发育的毒性最强。8号站位（位于主航道并濒临嵩屿电厂）的水样对鱼卵胚胎发良的毒性次之，1号站位（湾口）和5号站位（内港）的水样对鱼卵的胚胎发育的毒性较小。水样中的PAHs含量分析结果表明，仅用水样中的PAHs含量不能全面地反映水样对鱼卵胚胎发育的毒性。最后，对本实验方法应用于海洋环境生物监测的有效性进行了探讨。     

长江南通段污染带影响因素研究

通过建立应用贴体坐标系和有限体积法求解的二维水流－水质方程的模型，对潮汐河口南通段污染带的影响因素进行研究。揭示了水深、水面比降、纵向及横向混合系数以及污染物的排放时段与污染带范围的相关关系，并进行了各影响因素的灵敏度分析，对灵敏度大小进行了排序：水深＞水面比降＞横向混合系数＞纵向混合系数＞排放时段。     

Fluoride distibution and the effect of some ions along Alexandria coastal Mediterranean seawater of Egypt

The coastal seawater of Mediterranean of Alexandria receives large amount of discharged waters containing industrial wastes, sewage, and agricultural and domestic drainage. Fluoride and some parameters were(chemical and physical) determined. The data gave indication that the content and the amount of the discharged water largely affect the chemical composition of the coastal water. Stepwise regression analysis was highly significant and the model was very fruitful, where the observed and calculated values were mostly concordant. This may indicated that there was a relation between fluoride content in coastal seawater and its content in the discharged water.

山东省森林资源与木材供需平衡模型的建立与应用

本文在对山东省森林资源和木材供需平衡状况进行系统分析的基础上，利用系统动力学方法建立了山东省森林资源与木材供需平衡模型，通过对不同方案的政策仿真和结果分析，试图提出解决山东省木材供需矛盾的最佳途径，为制定林业发展政策提供依据。     

海水烟气脱硫初探

分析了金山卫，定海，北仑港和台州等地的海水成份，测定了它们的缓冲能力，在鼓泡反应器中进行了海水吸收ＳＯ２的静态试验和使吸收液中ＳＯ３＾２－转变为ＳＯ４＾２－的氧化试验，试验结果表明海水具有用作烟气脱硫吸收液的可能性和吸收液经曝气后直接排海的可能性。     

Pitfalls in the prenatal diagnosis of peroxisomal β-oxidation defects by chorionic villus sampling

Variability in the level of expression of very long chain fatty acids (VLCFAs) is documented in cultured chorionic villus (CV) cells derived from two fetuses, one at risk for an unusual peroxisomal fatty acid β-oxidation defect, and the other at risk for the X-linked form of adrenoleucodystrophy (ALD). Cells from early subcultures of chorionic cells from both cases gave normal values for VLCFA ratios. The results for the fetus at risk for the β-oxidation defect were interpreted to indicate that the fetus was not affected; however, at birth, the infant was clinically and biochemically affected. In the case of the fetus at risk for X-linked ALD, although VLCFAs were normal in subculture 1, the levels of these fatty acids increased dramatically in subculture 3, suggesting an abnormal fetus. Termination of the pregnancy and subsequent biochemical and morphological follow-up confirmed that the fetus was indeed affected by ALD.
