ECMA (European Catalyst Manufactures Association, established in the early 1980's to provide a forum whereby environmental and safety aspects of production, storage, use and disposal of metal/metal oxide containing catalysts should be discussed), decided to establish what the catalyst industry was capable of achieving in their processes. Because currently available monitoring data for nickel ex-member companies, was insufficient, two nickel monitoring surveys were executed to obtain comprehensive and comparable data on exposure to nickel during catalyst manufacturing operations, from a large number of catalyst producers. ECMA compiled program details in order to ensure that a standard methodology was followed by all participants; the program consisted of personal dust sampling, urine-analysis and a questionnaire on process details. Relationship between airborne and urinary nickel levels was investigated using regression methods. Unlike the findings of some reports it was found that there was no simple correlation between the parameters, probably by the variance in type of nickel compound. The effect of using a dust mask, length of exposure, exposure to insoluble nickel and smoking habits on urinary nickel concentration was investigated by analysis of variance. Despite significantly lower atmospheric exposure to water soluble compared with insoluble nickel compounds, there was no significant difference in urinary nickel concentration. The efficacy of dust masks in reducing the body burden of nickel was confirmed. There was no significant difference between the urinary nickel concentration of smokers and non-smokers in the non-exposed groups.","PeriodicalId":77768,"journal":{"name":"Polish journal of occupational medicine","volume":"2 4","pages":"357-66"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13636705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the welding fume samples collected on a membrane filter, total chromium was determined with atomic absorption spectrophotometry (AAS). Glass filters with collected samples were divided into two parts. In one part of the sample, soluble and insoluble chromium was determined by means of AAS. The separation of soluble chromium III and VI was carried out on diphenylcarbazide resin. In the second part of the sample total chromium VI was determined by means of the colorimetric method with s-diphenylcarbazide. The difference in the results of these determinations allowed the calculation of the content of total Cr III, Cr III insolub. and Cr VI insolub. The results of determining chromium compounds in welding fumes samples collected in the welder's breathing zone and in experimental chambers are also presented in this paper. The content of total chromium in the fumes determined by AAS (from a membrane filtr) and that calculated from the sum of soluble and insoluble chromium (from a glass filter) were concordant and within the limits of the admissible error for the method. Total chromium content in welding fume samples collected individually was found to range from 2.4-4.2%. The percentage of particular chromium compounds as compared to total chromium (100%) amounted: total Cr III--34%, total Cr VI--66%, soluble chromium--66% and in this Cr III--20% and Cr VI--43%, insoluble chromium--34% and in this: Cr III--14% and Cr VI--20%.","PeriodicalId":77768,"journal":{"name":"Polish journal of occupational medicine","volume":"2 4","pages":"376-88"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13636707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five of the investigated dyes (Acid Blue 7, Acid Green 16, Direct Black 19:1, Basic Red 22, Basic Orange 28) possessed mutagenic activity with regard to test strains of Salmonella. In addition, all of them increased the frequency of micronucleated polychromatic erythrocytes in the bone marrow of mice. Three other compounds (Acid Blue 62, Direct Yellow 12, Direct Red 81), which were not mutagenic in the Salmonella/microsome assay, were genotoxic in the micronucleus test. The other two dyes (Reactive Blue 13, Acid Red 213), as well as tested surface active compounds, did not exert mutagenic and genotoxic effects, and therefore, it is most probable that they do not have carcinogenic properties. Besides, it was noted that Acid Blue 62, Direct Black 19:1, Direct Red 81 and Basic Orange 28 cause a significant decrease in the ratio polychromatic to normochromatic erythrocytes in the bone marrow of mice, which means that, at the doses used in the experiment, they are toxic to the erythrocyte series cells of bone marrow. The other compounds under consideration have no such effect.","PeriodicalId":77768,"journal":{"name":"Polish journal of occupational medicine","volume":"2 2","pages":"171-85"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13633360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results concern the three year period between 1985 and 1987, during which the observed annual average concentrations were stable and have been recognised as values corresponding to the steady state. They are presented and analysed assuming several possible values of the Authorized Limit of the exposure of miners to radon daughter products. The values: 1 WLM, 2.5 WLM, 3.5 WLM (Working Level Month) were considered and compared with the value of 5 WLM, which is currently the basic limit recommended by the International Commission on Radiological Protection (ICRP), and approved by the WHO, ILO and IAEA. Though the value of 3.5 WLM is presently adopted and officially authorized in Poland as the Authorized Limit of annual individual miners' exposure, the results presented in this paper lead to the conclusion that the value of 2.5 WML could be adopted instead of the current one. This means that the present limit could be decreased by about 30% and without causing any social, technological and economic problems in Polish metal-ore mines.","PeriodicalId":77768,"journal":{"name":"Polish journal of occupational medicine","volume":"2 1","pages":"76-86"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13635586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
