    When fossil fuels are burned with air, some of the oxygen and nitrogen present combine to form nitrogen oxides. Their concentrations depends upon variables such as flame temperature, oxygen concentration and nitrogen content in fuels.
    Because of the absence of practically available techniques for removing nitrogen oxides from flue gases, the efforts are focused to the combustion modification techniques for eliminating the nitrogen oxide emissions. The present status of their development, such as two stage combustion, flue gas recirculation, off-stoichiometric combustion and etc., are described in this paper.
    Some problems for the determination of nitrogen oxides in flue gases are also described here.

  • Respiratory Effects of Nitrogen Dioxide and Ozone in the Industrial and Urban Community Atmospheres
    Eiji Yokoyama

    Review of the respiratory effects of experimental, occupational, and community exposure to nitrogen dioxide (NO2) and ozone (O3) is presented. NO2 and O3 can penetrate the respiratory upper airway more readily than can SO2, and this difference in the penetration rate may be one of the causes for that the pulmonary damages with relatively high concentrations of NO2 and O3, deep irritant, are different from those with SO2. More detailed researches are required for evaluation of lower concentration effect of these gases, but it is emphasized that in addition to its own deleterious effect on the lung, NO2 is a causative agent of photochemical oxidants.

  • Catalytic Removal of NOx in Gases

    Recently NOx has been very much in the newspapers as the main cause of photochemical smog, and is spoken as the representative of environmental pollution, together with SO2.
    As is generally known, NOx appears as simple substance, compound or polymer, changing its shape and form, according to the time and circumstances. Accordingly, it is one of the most difficult tasks to analyze the quality of each substance, since it concerns with all the aspects.
    I have devoted myself to the study of this field for a long time, and here listed, for your reference, some of literatures about NOx to the limit of paper space, which I have collected so far.

  • Analytical Method of Polynuclear Hydrocarbons in Petroleum
    Hidetsuru Matsushita

    This Paper describes on the analytical methods for polynuclear hydrocarbons in petroleum. Special emphsis was put on the microanalytical method which was composed of extraction of polynuclear hydrocarbons by liquid-liquid partitions, separation of the extract into each component by two-dimensional dual band thin layer chromatography, and Identification and determination of the isolated hydrocarbons by spectrofluorometry.
    Polynuclear hydrocarbons detected from several petroleum such as kerosine, fuel oil, residuum oil, catalytically cracked residuum oil, petrolatum, and wax were listed. Contents of several polynuclear hydrocarbons including benzo (a) pyrene, a potent carcinogen, in some petroleum were also given.

  • About the Propriety of Dispersing Method for Spilled Oil on Sea
    Goro Kondo, Takeshi Hashimoto, Osami Nishida

    At the treatment of spilled oil on sea, dispersing method using oil dispersers is frequently applied and the toxicity of oil disperser has been called in question. We studied on the toxicity of marketed oil dispersers and some of them were found to be almost non-toxic.
    We also studied on the toxicity of oil itself and found the oil in floating state had low toxicity for fishes, nevertheless dispersed oil droplets had high toxicity and the toxicity of oil dued to the aromatic and naphthenic component contained in oil.
    We compared the damage of environment caused by both floating oil layer and dispersed oil droplets and deduced as follows;
    1. Spilled oil when abandoned as floating oil layer has low toxicity for fishes, but gives heavy damages to marine life on sea surface (laver or sloke) and the pollution of environment will continue for long period.
    2. Spilled oil when treated by oil dispersers comes into sea water as fine oil droplets which have high toxicity for fishes but the damages of marine life on sea surface are controlled locally and the pollution of environment will discontinue in short period by natural digestions.
