    Description / Table of Contents: Zusammenfassung Die Situation bei potentiell cancerogenen Chromverbindungen in der Liste der maximalen Arbeitsplatzkonzentrationen (MAK-Werte) 1978 wird geschildert. Ein empirisch-kasuistischer Bericht über 27 Fälle von Lungenerkrankungen nach Exposition gegenüber verschiedenen Chromverbinduneen schließt sich an. Zur Auswertung gelangten dabei Unterlagen der Berufsgenossenschaft der Chemischen Industrie aus sieben Firmen mit Expositionszeiten zwischen 1899 und 1968. In tabellarischer Form werden Angaben fiber 14 Fälle von Bronchial-carcinom nach Exposition gegenüber Chrom-VI-Verbindungen, drei Fälle von Bronchialcarcinom nach Exposition gegenüber Chrom-III-Verbindungen, acht Fälle von Lungenerkrankungen ohne Carcinom und zwei weitere Fälle gemacht. Unter Bezug auf these Daten und die neuere Literatur erfolgt eine Diskussion anhand von Kriterien zur Anerkennung bösartiger Neubildungen als Berufskrankheit. Die Wahrscheinlichkeit bzw. Möglichkeit von Ursache und Wirkung wird diskutiert. Die Bedeutung von arbeitsmedizinischen Vorsorgeuntersuchungen am entsprechend exponierten Arbeitsplatz and besonders die Chrombestimmung im Urin als Nachweis einer Einwirkung wird hervorgehoben.
    Notes: Summary The present situation concerning potentially cancerogenous chromium compounds listed in the table of threshold limit values (TLV's) is described, followed by an empirical case report on 27 cases of diseases of the lung after exposition to various chromium compounds. A documentation of the ‘Berufsgenossenschaft der Chemischen Industrie’ (Association of the Chemical Industry) covering seven companies with exposition times between 1899 and 1968 was evaluated for this report. Information on 14 cases of bronchial carcinoma after exposition to chromium-VI compounds, on three cases of bronchial carcinoma after exposition to chromium-III compounds, eight cases of lung disease without carcinoma, and two additional cases is presented in the form of tables. A discussion concerning the criteria of confirmation of new malignancies as occupational diseases, based on the data presented and on recent literature, follows. The probability, and/or the possibility of cause and effect is discussed. The importance of preventive check-ups in the field of occupational medicine at the working locations, correspondingly exposed, and particularly the determination of chromium in the urine are emphasized.

    Notes: Summary Twenty glass industry workers from three plants exposed to different atmospheric HF-levels have been studied with respect to their renal fluoride excretion. Analyses have been carried out on preshift and post-shift urine samples as well as on 24-hour urine. In addition, the fluoride concentration of the working atmosphere has been determined. Intake — excretion balances showed that the total renal fluoride excretion was between 10 and 60 % of the inhaled HF. The results lead to the conclusions: 1. There exists a direct correlation between atmospheric fluoride concentration and renal fluoride excretion (r = 0,8615). 2. There exists a significant correlation between total daily elimination of fluoride and the fluoride concentration in post-shift urine-samples (r = 0,9324). 3. As the atmospheric HF-concentration increases there appears to be a decrease in the amount of fluoride renally eliminated. 4. There is no evidence for a statistical relationship between urine fluoride concentration and long term exposure. 5. Urine fluoride analyses of post-shift samples present a suitable monitoring method for persons exposed to HF. An assessment of a dose and response relationship is dependent upon the knowledge of the specific exposure at the working place. The physical and chemical state of the inhalation noxious (e.g. gaseous HF or fluoride containing dust) ist important. Thus the results from studies in the aluminium-industry (dust) cannot be compared with those obtained in the glass industry (gaseous HF).

    Description / Table of Contents: Zusammenfassung Auf der Basis des Belastungs-Beanspruchungs-Konzepts wurden Pilot-Untersuchungen an zwei beruflich PCP-belasteten Kollektiven durchgeführt. Ein Kollektiv ist mit der Herstellung PCP-haltiger Holzschutzmittel beschäftigt (n = 18), die andere Gruppe wendet dieses Mittel an (n = 23). Das Untersuchungsprogramm beinhaltete sowohl Messungen zur externen (PCP in der Luft) bzw. internen Belastung (PCP im Urin und Serum) als auch klinisch-chemische und immunologische Bestimmungen zur Erkennung von Wirkungen auf das Zielorgan Leber. Die PCP-Luftkonzentrationen an den einzelnen Arbeitsplätzen lagen im Mittel um den Faktor 30 (Herstellung) bzw. 200 (Anwendung) unter dem derzeit gültigen MAK-Wert von 500 μg/m3. Die PCP-Plasmakonzentrationen betrugen 0,02 bis 2,4 μg/ml. Die PCP-Ausscheidungen im Urin variierten von 6 bis 2111 μg/g Kreatinin. Diese Werte liegen deutlich oberhalb der fur das Vergleichskollektiv ermittelten Werte. Kein Zusammenhang bestand zwischen Dauer und Ausmaß der Exposition und Konzentration von PCP im biologischen Material. Die Ergebnisse der immunologischen Untersuchungen ergeben bei sechs Personen auffällige Befunde. Für diesen als erhöhte mesenchymale Aktivität interpretierten Anstieg der Immunglobuline war kein Dosis-Wirkungs-Zusammenhang wahrscheinlich zu machen. Bei den klinisch-chemischen Untersuchungen konnten deutlich erhöhte Serum-GLDH-Aktivitäten in beiden PCP-Kollektiven nachgewiesen werden. Im Kollektiv, das mit der Herstellung PCP-haltiger Holzschutzmittel beschaftigt war, wiesen ca. 40% eine isolierte Erhöhung der Serum-GLDH-Aktivitat auf, ohne daß wahrscheinlich alkoholische, durch Verunreinigungen bedingte oder virale Einflüsse eine Rolle spielen.
    Notes: Summary Based on the concept of dose and effect, pilot studies were carried out on two groups of persons occupationally exposed to pentachlorophenol (PCP). The members of the first group are engaged in the production of wood preserving agents containing PCP (n = 18), the persons of the second group are applying these agents (n = 23). The program of investigations involved measuring the external (PCP content of the ambient air) and the internal PCP-dose (PCP levels in urine and plasma) as well as determining clinical-chemical and immunological data for evaluation of eventual effects on the liver as a target organ. The concentrations of PCP in the ambient air at the workplaces were on the average a factor of 30 (group engaged in the production), and a factor of 200 (group using these agents) lower than the presently accepted MAK-value of 500 μg/m3. The concentrations of PCP in the plasma ranged from 0.02 to 2.4 μg/ml. The renal-excretion of PCP varied between 6 and 2111 μg/g creatinine. These values are markedly higher than the values found in the controls. No correlation was revealed between the duration and the extent of exposure to PCP and the concentrations of PCP in the biological materials. In six persons the immunological investigations yielded significant findings. For this rise of the immunoglobulines, which was interpreted as the result of an increased mesenchymal activity, no dose/effect relationship was conclusively proven. During the clinical chemical investigations, markedly elevated serum GLDH-activities were demonstrated in both groups of persons exposed to PCP. In the group of persons engaged in the production of wood preserving agents containing PCP, approx. 40% of the persons exhibited an isolated elevation of the serum GLDH-activity. The simultaneous influence of alcohol, contaminants in the wood preserving agents, or viruses were unlikely.
