采用甘蓝叶表法对5种渗透剂进行了筛选,在此基础上,采用幼虫浸渍法和叶片药膜法测定了JFC-2、TX-10和FP-T等3种渗透效果较好的渗透剂对阿维菌素的增效作用,及它们分别与阿维菌素混配后对甘蓝叶片渗透量的影响.结果表明,当阿维菌素药液中含有渗透剂的浓度分别为50、100、200mg/L时,渗透剂JFC-2对阿维菌素浸渍法毒力的增效比分别为1.54、1.74和2.16,叶片药膜法毒力的增效比分别为1.60、1.90和2.18;TX-10的浸渍法毒力增效比分别为1.47、1.70和1.97,叶片药膜法毒力的增效比分别为1.48、1.63和2.00;FP-T的浸渍法毒力增效比分别为1.56、1.59和1.78,叶片药膜法毒力的增效比分别为1.58、1.52和1.86;同时,上述3种渗透剂还可提高阿维菌素对甘蓝叶片的渗透速度,缩短渗透时间.图1表3参11     

水中直链烷烃的光敏化降解

采用实验室模拟方法，研究了水中直链烷烃光敏化降解的途径，结果表明，经紫外光照射烷烃可被激发态的敏化剂抽取一个氢原子而形成烷基。在有氧条件下，它可形成烷氧自由基，进而被氧化成相应的酮。如果烷氧基中有γ－氢原子存在，它可通过类似于ＮｏｒｉｓｈⅡ型重排反应，而生成短碳链的甲基酮，烯烃以及小分子量的乙烯、环氧乙烷、乙二醇、丙酮、甲醛等。

改性大豆蛋白海上溢油凝油剂的制备与性能

大豆蛋白羟甲基化后，再用高级脂肪酸酰氯酰化，然后以多价金属离子盐处理，得到的凝油剂具有良好的凝油性能，可用于水面原油与燃料油的回收处理。进一步研究发现，三价金属离子形成的凝油剂的凝油性能比二价金属离子形成的凝油剂的凝油性能好；羟甲基大豆蛋白酰化时所用的酰氯的碳原子数越大，凝油速度越快；凝油剂对原油的凝油性能比对柴油的凝油性能更好；水的盐度对凝油剂的凝油性能无明显影响。

治理套外返污水的油井、水井

由于固井质量不合格或是套管破裂、错断引起的油井和水井套返污水，造成了吉林油田老油区普遍的环境污染。从１９９０年开始，通过反复的摸索和试验，提出并逐渐完善了两种切实可行的治理方法，即封堵剂法和封隔器法。实践证明，效果良好。     

Tributyltin distribution and producing androgenic activity in water,sediment, and fish muscle

This study investigated the concentrations of Tributyltin (TBT) in water, sediment, and fish muscle samples taken from Kaohsiung Harbor and Kaoping River estuary, Taiwan. TBT concentrations in water and sediment samples ranged from less than 18.5 to 34.1 ng Sn L^?1 and from 2.44 to 29.7 ng Sn g^?1 weight per weight (w/w), respectively. Concentrations in the TBT‐contaminated fish muscle samples ranged from 10.8 to 79.6 ng Sn g^?1 w/w. The TBT concentrations in fish muscle were higher than those in water and sediment samples. The fish muscle/water TBT bioconcentration factor (BCF) ranged from 590 to 3363 L kg^?1. Additionally, the water samples were assessed for androgenic activity with an MCF7‐AR1 human breast cancer cell line. The androgenic activity ranged from 0.94 to 3.1 ng‐dihydrotestosterone per litre water (ng‐DHT L^?1). Higher concentrations of TBT in water and sediment samples occurred in the dry season, but the androgenic activity had higher values in the rainy season.     

Converting wasteland into wonderland by earthworms—a low-cost nature’s technology for soil remediation: a case study of vermiremediation of PAHs contaminated soil

Earthworms in general are tolerant to many chemical contaminants including heavy metals and organic pollutants in soil and can bio-accumulate them in their tissues. Earthworms species like Eisenia fetida, Eisenia tetraedra, Lumbricus terrestris, Lumbricus rubellus and Allobophora chlorotica have been found to remove heavy metals (Cd, Pb, Cu, Hg, etc.) pesticides and lipophilic organic micropollutants like the polycyclic aromatic hydrocarbons (PAH) from the soil. They ‘absorb’ the dissolved chemicals through the moist ‘body wall’ in the interstitial water and also ‘ingest’ by mouth while the soil passes through the gut. They either ‘bio-transform’ or ‘biodegrade’ the chemical contaminants rendering them harmless in their bodies. Meanwhile the quality of the soil is improved significantly in terms of physical, chemical and biological properties as the worms thoroughly upturn and disperse the soil, ingest large volumes of soil and excrete nutritive materials (NKP and micronutrients) in the form of ‘vermicasts’ along with millions of beneficial soil microbes including nitrogen fixers.
