ジャーナル フリーForm of tidal river cycle and determination mdthod of water qualities were investigated at the tidal areas of river ran with industrial waste and domestic sewage, and the following results were obtained. 1. Direction of tide is changed by branching and by curve of river. 2. Stay of polluted substances could be removed by controlling discharge of waste water and sewage according to the direction of tide. 3. In the case of wide river containing sea water several sampling points must be settled across the river and aliquats from both upper and lower layers should be drawn out as test samples in accordance with water depth. 4. In the branches of tidal river no increase of chloride was observed at high tide, and this seemed to be check phenomenon by main stream.抄録全体を表示PDF形式でダウンロード (718K) -

ジャーナル フリーThe gas chromatographic analysis of 11 kinds of local anesthetics were reported in the preceding paper. Paper electrophoresis, thin-layer chromatography and paper chromatography impregnated with zirconium phosphate were studied for these local anesthetics. The effective solvent systems for separation and the suitable color reagents for detection of these anesthetics were also investigated. By combining these results, an analytical system which successfully achieved the separation and identification of each compound in a mixture of these anesthetics was established.抄録全体を表示PDF形式でダウンロード (521K) -

ジャーナル フリーGas chromatography was applied for the identification of 5 pharmaceuticals which contain bromisovalerylurea and other drugs. The gas chromatography of the standard compounds in ethanolic solution was performed by using a column containing 1.5% carbowax and 2.5% SE-30 as the stationary phase. The discrimination from each other of these 5 pharmaceuticals was successfully achieved by using above gas chromatographic method. The application of the method for forensic purposes was also reported.抄録全体を表示PDF形式でダウンロード (686K) -

ジャーナル フリーThe conversion of local anesthetics in human cerebro-spinal fluid was investigated in vitro and an improved method for analysis of the local anesthetics in cerebro-spinal fluid was proposed. When hexylcaine, procaine and tetracaine were incubated with cerebro-spinal fluid, ester bonds of the compounds were hydrolysed mainly due to the increase of pH of cerebro-spinal fluid on standing, while amide bonds of dibucaine, lidocaine and carbocaine were unchanged. In the analysis of local anesthetics in cerebro-spinal fluid, it is desirable to estimate the ultra-violet spectrum of the sample and to determine the aromatic carboxylic acid liberated, as well as the determination of the unchanged anesthetics.抄録全体を表示PDF形式でダウンロード (668K) -

ジャーナル フリーRapid determination of oxygen in atmosphere with detector tubes was studied. Detecting reagent was prepared by addition of alkaline pyrogallol solution to activated alumina particles and changed its color from white to brown by oxygen in atmosphere. Detector tube is a small glass tube packed with the detecting reagent, through which 50 ml of sample gas is passed in 100 sec. with a syringe. Two∼thirty per cent concentration of oxygen in atmosphere is easily measured by this method from the length of brown zone of detector tube colored by oxygen. The value obtained by the proposed method should be corrected by the correction table, if coexisting carbon dioxide concentration is above 5 %. The temperature of the detector tube gives no effect on the values determined by the proposed method within the range of 5∼40°C.抄録全体を表示PDF形式でダウンロード (593K) -

ジャーナル フリーInvestigation was carried out on some kinds of domestic wares containing natural radioactive substance. These articles, namely a pillow, a tile plate, a belt and so on, are produced in a particular factory and are sold in market with special advertisement for keeping health or for utilizing their weak radiation. The radioactive substance contained in these articles was prepared from a kind of ore called Monazite. The γ-spectrum of this sandy ore with Malti-channel Pulse Height Analyzer was quite identical to that of thorium, and the thorium content was 4.7∼23.7 percent by chemical analysis. We found considerable dose of radiation derived from these articles with Lauritzen electroscope as shown in TABLE I. It is very difficult to consider if these articles might be safe for life, because we can not know the actual dose of radiation during use of them. However, roughly speaking, these articles may not be safe for health, if they are used very freely. We are feeling that we should have a scientifically authorized safety limit or alarm level of the radioactivity for use of these domestic wares.抄録全体を表示PDF形式でダウンロード (1625K) -

ジャーナル フリーAir pollution in Tajimi city and Kasahara town, where many china factories are located, was observed by the filter paper method at 15 observation points from June, 1964 to May, 1965. In Tajimi city and in Kasahara town, 256 and 131 china factories exist, respectively, and heavy oil is used in most of these factories as fuel. From the results of this investigation, it was shown that sulfur oxide values in agricultural area were the lowest, 0.02-0.22 mg SO3/day/100 cm2 paper, and in commercial and industrial area, the values were 0.04-0.72, and 0.05-0.68 mg SO3/day/100 cm2 paper respectively. Sulfur oxide values were the lowest in September and October, but were the highest in November, December and January. Nitrogen dioxide values at these observation points were comparatively high, 0.01-0.09 mg NO2/day/100 cm2 paper, and increased in winter, too. Chloride ion values were very low, and fluorine values were relatively low.抄録全体を表示PDF形式でダウンロード (529K)
