  tnt
Using Bacillus subtilis SK1 as an example, it was demonstrated for the first time that 2,4,6-trinitrotoluene (TNT) transformation pathways change with TNT concentration.
      
subtilis SK1, delayed at 20 mg/l TNT (minimum toxic concentration), was resumed following TNT transformation.
      
Aromatic amines were predominant metabolites detected in the culture medium at early stages of TNT transformation.
      
The culture growth was completely inhibited by 200 mg/l TNT.
      
The sensitivity of Escherichia coli strains K-12 and 055 to 2,4,6-trinitrotoluene (TNT) was found to correlate with the structural and functional properties of the outer lipoprotein membrane.

TNT, BHC, DDT, Parathion and HgCl2 were used separately in acute toxicity tests on the Silver Carp, Hypophthalmichthys molitrix. Serum glutamic oxalocetie transaminase activity level in the treated fish was significantly increased. Glutamic pyruvic transaminase level was effected by Parathion. The degree of elevation of serum trausaminase activity is related to the concentration of mercuric chloride.The age and species of various Chinese freshwater Cyprinids, different types of water bodies, short term starvation, disturbance and cage culture all had no effect on serum transaminase activity.But a rise in water temperature or an impoverishment of dissolved oxygen content to a level below 1 ppm increased fish serum glutamic oxalocetie transaminase and glutamic pyruvic transaminase activity. Pish serum glutamic oxalocetie transaminase activity is correlated to water temperature.

以三硝基甲苯(INT)、六六六、滴滴涕(DDT)、对硫磷(E-605)、氯化汞分别进行白鲢鱼种的急性致毒实验,与对照组相比,鱼血清谷草转氨酶活性显著增加;对硫磷还引起血清谷丙转氨酶活性的升高。血清转氨酶活性增加的程度与氯化汞浓度相关。不同种类的我国淡水鲤科鱼类、不同鱼龄、不同水体以及短期饥饿、惊扰及网箱饲养对血清转氨酶活性没有影响,但水温升高或溶氧低于1ppm会使鱼血清谷草转氨酶活性升高。水温与鱼血清谷草转氨酶活性有相关性。

A projectile with ground-air rocket by the burst of TNT has been designed for dispersing metaldehyde (MA) into the clouds on a large scale. The threshold temperature of MA on ice nucleation in laboratory is around -1℃. The projectile is made of proper dosage, with TNT in its core and-MA in its outer layer. The result of the experiment for explosion shows that the number of MA particles dispersed by the burst of TNT reaches the order of 10~(12) I/gm and that of ice nucleation is 10~7~10~(10)...

The result of the experiment for explosion shows that the number of MA particles dispersed by the burst of TNT reaches the order of 10~(12) I/gm and that of ice nucleation is 10~7~10~(10) 1/gm in the temperature range of -1℃~-15℃. The quantitative analyses of collected products for explosion show that the loss of MA due to burning or decomposition augments with the increasing amout of TNT used, but its remains are more than 71%. The ability of forming ice of MA which has been stored for one year or more decrasses by about one order of magnitude. The result of the experiments of quick toxicity on account of ingested AM shows that the the L_(D50) for large rats counted by means of Horn's method is 316 mg/kg, the limit of 95% Confidence is 169~592 mg/Kg. For the sake of comparison, some experimemts of ice nucleation of AgI have been carried out in the laboratory, showing the number of ice crystals is 10~6 1/gm~10~(12) 1/gin within -5℃~13℃. In comparison with the ice nucleation ability of Agl-acetone solution, it is shown that MA is more efficient than AgI to modify the supercooled clouds above -6.5℃.

为了地面利用小火箭有效地对云大量撒播介乙醛,我们设计了一种用TNT分散介乙醛的药桂。室内实验测定介乙醛的成冰阈温在-1℃左右。选取合适的配方压制以TNT为内芯,介乙醛在外层的药桂。爆炸试验表明:介乙醛产生的微粒数达12~(12)个/克,在-l℃~15℃范围内产生的冰晶数为10~7个/克~10~(10)个/克以上。对爆炸后收集的产物分析表明:介乙醛因燃烧或分介的损失量随TNT用量的加大而增加,而其保存量均在71%以上。贮存一年以上的介乙醛,其成冰能力降低一个量级左右。介乙醛急性经口毒性试验表明:大白鼠用Horn氏法计算L_(D50)为316毫克,公斤,95%的可信限为169~591毫克/公斤。为了对比起见,对AgI的成冰能力也作了爆炸试验,实验表明,在-5℃~13.5℃范围内,AgI产生的冰晶数为10~6个/克~10~(10)个/克。将介乙醛与AgI-NaI-丙酮溶液的成冰能力相比较,发观温度高于-6.5℃时,作为冷云催化剂来说,介乙醛比AgI要更为有效。
