They have close relationship as the former may provide new ideas and approaches for the later, while the later may be the simulation for the former and gives it helps in degradation products identification and mechanism explanation. It is necessary to choose a suitable system, which has high potential of treating EDs and close relationship to the natural environment, to combine the researches in the two aspects. Our group has been engaged in researches on the photochemical properties and application to water pollution control of different ferric species including Fe -OH complexes, Fe -polycarboxylate complexes, Ferric oxides and Fe -humic acid complexes. Fe -oxalate complexes system has higher efficiency than the other ferric species systems in photooxidation and degradation of organic compounds. This thesis is focused on the photodegradation of nine EDs estradiol (E2), estrone (E1), 17α-ethynyl estradiol (EE2), diethylstilbestrol , bisphenol-A , 4-Nonylphenol , 4-Octylphenol , di-n-butyl phthalate , and di (2-ethylhexyl) phthalate .

In order to overcome the shortage of conformable precision, polyamide affinity membrane modified by cibacron blue F3GA was introduced into the pretreatment unit to get rid of interferer from large molecule such as albumin in serum. The affinity membrane was combined with micro-fluidic chip by embedded and external methods and using external-combination pretreatment unit, average enrichment was 89.36 times, RSD was 4.37%.

为了提高测试的精密度，进而设计含膜复合式预处理芯片，探讨了不同预处理单元对血清样品中痕量盐酸多巴酚丁胺富集效率的影响，优化设计了外接式硅胶整体柱－亲和膜微芯片固相萃取预处理单元，复合式的反相硅胶整体柱对血清中微量盐酸多巴酚丁胺的平均富集倍数提高到89.4，RSD为4.37%。

Amounts of 2 furaldehyde and 5 hydroxymethyl 2 furaldehyde in wood vinegar from the treated wood were increased,but amounts of carboxylic acids,phenols,pyrocatechol,guaiacols,and maltol were almost constant.

与未处理材相比，处理材木醋液中糠醛及5 羟甲基糠醛的收量增加，而羧酸类、苯酚类、邻苯二酚、愈创木酚类及麦芽酚的收量几乎不变。

Even's air-drying method for meiotic preparations from germ cells of mammalian testes improved by our laboratory was used and dynamic change of division figure of prophase 1 in the mouse treated by testosteronic propionas and stilbestrol was observed.

采用本室改良的Evens哺乳动物睾丸生殖细胞减数分裂空气干燥法制片技术，观察了用丙酸睾丸酮和已烯雌酚处理小鼠第一次减数分裂前期分裂相染色体的动力学变化。

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 showed that in the growth period of R. glutinosa, soil ferulic acid, vanillic acid, and vanillin contents had a persistent increase, while β-hydroxybenzoic acid content increased first but decreased then. The addition of ferulic acid (8 μg·ml-1), vanillic acid (08 μg·ml-1), vanillin (12 μg·ml-1), and β-hydroxybenzoic acid (30 μg·ml-1) in water culture had stronger inhibitory effects on R. glutinosa root length, root mass, fresh plant mass, and plant height. Treating with test phenolic acids except β-hydroxybenzoic acid increased leaf chlorophyll content significantly, compared with the control. After treated with test phenolic acids, plant SOD and POD activities decreased after an initial increase, and plant malondialdehyde content increased. In the treatment of ferulic acid, root SOD and POD activities were the lowest, and roots were rotted and dead.
