With the aid of the bibliographic standard literature on industrial, social and preventive medicine, all experimental investigations of this subject and published since 1970 were considered. The important results and findings are presented in tabulated surveys broken down by the substances contained in smoke. The present results of investigation are discussed with respect to a practical workplace model whose air-hygienic conditions are determined by legal prescriptions for workplaces. The measured concentrations of the particulate mass and of the most important individual constituents of smoke, carbon monoxide, nicotine and aldehyde make it highly unlikely that passive smoking at the workplace causes injury to health if the prevailing regulations governing the workplace are complied with. Particular attention has to be given to the occupational problems existing in night bars, restaurants and discothecs.</p>","PeriodicalId":76867,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

Its reduced virulence for the chick embryo, for experimental animals and for man is a particularly characteristic feature. With the exception of chick embryo fibroblasts, the MVA virus grows in cell cultures only abortively. This applies particularly to cells of human origin in which the cytopathic effect and plaque formation are completely missing. The restriction analysis of the DNS of the MVA virus demonstrates that its genetic structure differs from that of the CVA basic virus and other orthopox viruses. In contrast to the WHO reference strain Elstree, the MVA virus has a genome shortened by about 9 per cent. The use of the MVA virus for human vaccination is particularly indicated in persons to be vaccinated for the first time and likely to entail a risk (on account of allergies etc.) because it brings about a state of revaccination without complications. The MVA virus can be administered in intracutaneous, subcutaneous or intramuscular injections. Innocuoursness and successful vaccination have been demonstrated in more than 120000 persons. While other Vaccinia strains, such as the Elstree virus, experience a drastic increase of virulence in the immunosuppressed organism (subjected to whole-body irradiation), the MVA virus cannot be activated not even in this situation.</p>","PeriodicalId":76867,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

The standard of assessment was taken from the German Drinking Water Regulation of 1975 which establishes a max. permissible mercury content of 4 ppb Hg for drinking water. In 70 per cent of the samples no mercury was detected. Of the remaining 30 per cent of the samples, about 90 per cent proved to have mercury below 1 ppb.
