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.

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)...

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) 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。

For practical purpose,the photooxidative kinetics of TNT aqueous solution has been studied using static and flowing methods in the laboratory.The results of experiments show that.(1) By the action of UV-H2O2,the photooxidative reaction of TNT aqueous solution follows the equation.Inc/c0=-kt(1),where c0 is the con-centration of TNT solution at t=0,c is that of TNT solution at anytime t;t and k being the time elapsed and rate constant of the photooxidative reaction.In terms of(l),the time required for the photooxidized TNT solution to meet the effluent concentration limit can be estimated.(2) under the same conditions(Intensity of UV,radiation area,film depth and the concentration of H2O2),the photooxidative reaction rate constant of TNT solution k is relaled to the initial concentration of TNT solution by the equation;lnk=-mc0+B(2),where k,c0 are the same as in(1),m and B are empirical constants.By means of(2),the saving of electrical energy due to dilution of TNT solution can be estimated.(3) The rate constant k is independent of temperature.(4) The rate constant k depends upon the initial concentration of H2O2.An optimum Value of the initial concentration of H2O2 exists,and it inc- reases as the concentration of the TNT solution increases.Applicability of the above found macrokinetic regularity of TNT solution in industrial TNT wastewater treatment should await further studyData obtained through liquid chromatography and thin layer chromatography show that the photooxidative process of TNT aqueous solution is rather a complex reaction.Its mechanism is a topic awaiting further study too.

为了实用的目的,在实验室进行了静态法与流动法研究TNT水溶液光氧化动力学实验。 实验结果表明: (1)TNT水溶液在UV—H_2O_2作用下遵循lnc╱c_0=-kt(1)的动力学方程式,式中c_0为TNT水溶液原始浓度,c为t时浓度,t为光氧化时间,k为光氧化速率常数。用(1)式可估计TNT水溶液光氧化达排放标准所需时间。 (2)光氧化速率常数k,在相同条件(UV光强,光照面积,液层厚度和H_2O_2浓度),与TNT水溶液初浓度有关,遵循lnk=-mc_0+B(2)关系,式中kc_0与(1)式同,m和B为经验常数。用(2)式可估算将TNT水溶液稀释以节约电能的程度。 (3)光氧化速率常数k与温度无关。 (4)速率常数k与H_2O_2初浓度有关,存在一最佳H_2O_2初浓度,而且此最佳值随TNT水溶液原始浓度增加而增大。 由液相、薄层色谱分析知此光氧化过程是一复杂反应,其机理正在进一步研究中,上述宏观动力学规律是否适用于工业废水也待确定。
