At the heavy metal concentration of 3-4ppm, our study on adsorption capacity, adsorption selectivity of montmorillonite, illite and kaolinite to Cu〓、 Pb〓、 Zn〓、 Cd〓、 Cr〓 shows that the adsorption capacity is mainly determined by the capacity of exchangeable cations and the adsorption capacity of the three clay minerals decreases in this sequence: montmorillonite ＞＞ illite＞kaolinite. It is found that clay minerals have obvious adsorption selectivity to various heavy metals. Montmorillonite exhibits a stronger affinity to Cr〓 and Cu〓 while kaolinite and illite sorb Cr〓 and Pb〓 more effectively. At the same heavy metal concentration, adsorption amount of clay minerals to heavy metals increase with increasing pH value of the solution.

The results show that the dissolution of Ag was restrained by forming of a silver suboxide film on the surface under low oxidant concentration and atmospheric pressure conditions (e.g., in NH_3-O_2-H_2O system); when the concentration of oxidant was high enough (e.g., in NH_3-H_2O_2-H_2O system), the leaching process was carried out without forming of the film and the rate of dissolution of Ag was controlled by a step of mass transfer.

结果表明，在常压下氧化剂浓度低时(如在NH_3-O_2体系中)，浸取反应受在Ag表面上生成的氧化物膜所阻碍；而在浓度足够高的氧化剂时(如在NH_3-H_2O_2体系中)，浸取过程可在不生成氧化物膜的条件下进行，此时Ag的溶解速度受传质步骤控制。

When the NP concentration exceeds 0.025 mg/L, the stability of DNA strands in shellfish will be affected and there will be a risk of carcinogenesis, mutagenesis and teratogenesis. Human health will also be affected due to seafood consumption. On the other hand, the DNA damage level and migration length show some difference among shellfish, oyster and clam exposed to the same nonylphenol concentration. This is because different shellfish species have different immunity to NP.

数据分析结果同时表明，在相同浓度的壬基酚处理组中，扇贝、牡蛎和文蛤血淋巴细胞的破坏率和迁移长度存在种间差异，这可能是由于这三种贝类对NP的免疫程度不同所致，但关于海洋生物对外界干扰因素存在不同免疫力的具体机制以及它们之间的差别，目前国内外的研究还不多见，具体研究还有待进一步的开展。

The results indicate seawater concentration has no effect on absorbency, pH, relative density, dry matter and water contents in Aloe vera leaves. While, seawater stress causes increased MDA and membrane penetration, decreased phytochroms, prolines and NO_3~--N. It is beneficial to plant growth when irrigation was done with 10% seawater, because of higher ratio of K~+/Na~+ and lower ratio of Na~+/Ca~(2+). In addition, the polysaccharide contents in Aloe vera leaves increase twice and triplication under 25% and 50% seawater irrigation respectively, the barbaloin contents increase over triplication in var. 75% seawater and over twice in var. 50% seawater and var. 100% seawater. However, when seawater concentration exceeds 25% the growth of plant was inhibited, biomass decreased, flowering time was deferred, Ca~(2+) content decreased caused by Na~+ accumulation in leaves.

结果表明：在海水胁迫下，库拉索芦荟全叶汁的吸光度、酸度、相对密度、总固形物和水分含量总体上受海水浓度的影响不大；但芦荟叶的丙二醛含量和质膜透性增加，叶绿体色素、脯氨酸和硝态氮含量减少；在10％海水浇灌下，芦荟叶细胞具有较高的K~+／Na~+比和较低的Na~+／Ca~(2+)比，对库拉索芦荟的生长有一定的促进作用；在25％海水和50％海水浇灌下，芦荟多糖含量提高了2-3倍；在75％海水浇灌下芦荟甙含量增加了3倍多，在50％海水和100％海水灌溉下，其含量也增加了2倍多；当海水浇灌浓度超过25％后，库拉索芦荟的生长明显受到抑制，生物量降低，抽苔期推迟，同时，海水浓度的增加也导致芦荟叶中累积大量Na~+，从而使得芦荟叶中Ca~(2+)含量降低，但Mg~(2+)并没有受到海水浓度的影响；用浓度低于75％的海水浇灌库拉索芦荟可以降低剖面深度在0-100cm之间的土壤盐度；其抗氧化保护酶中超氧化歧化酶的酶活力相对保持稳定，过氧化物酶的酶活力在10％海水浇灌下明显提高，随后则下降，而过氧化氢酶的酶活力则随海水浓度的升高而下降。

The type, initial feeding time and concentration of precursor for HV unit formation had great effects on PHBV production in shake flasks. Propionate was selected as the better precursor for HV fraction than valerate after comprehensive survey of these two precursors. The suitable PHBV shaking-flask culture conditions were obtained through the analysis of PHBV fermentation process, the investigation of several factors by using RSA method and the fed-batch experiments. Cell dry weight, PHBV content, PHBV concentration, HV fraction and yield coefficient of HV unit to propionate were 27. 7g/L, 80.7%, 22. 4g/L, 16. 1mol% and 0.50g/g, respectively.

在共聚物PHBV的摇瓶发酵过程中，PHBV中HV组分形成的前体物质的种类、初始加入时间以及加入量是影响PHBV发酵过程的重要因素；在综合比较丙酸和戊酸这两种前体的基础上，选择丙酸作为HV组分合成前体较适宜；通过对PHBV发酵过程曲线分析、影响PHBV发酵指标的各因素的响应面分析以及摇瓶发酵补料试验，得到了较适宜的PHBV摇瓶发酵补料条件，在此条件下，细胞干重、PHBV含量、PHBV浓度、HV组分含量和HV组分对丙酸的产率系数可分别达到27.7g/L、80.7％、22.4g/L、16.1mo1％和
