[Human biomonitoring investigations of organochlorine compounds -- PCB, DDE, HCB, beta- and gamma-HCH, PCDD/PCDF, Dioxin-like PCB's and polybrominated biphenyl ethers]. / Humanbiomonitoring-Untersuchungen von Organohalogenverbindungen -- PCB, DDE; HCB, beta- und gamma-HCH, PCDD/PCDF, koplanaren PCB sowie polybromierten Biphenylethern.

Although PCB and PCB-containing materials are not processed for a long time, PCB is under discussion again and again caused by the pollution of indoor environments. To objectify the discussion, the dates of the PCB-biomonitoring, the organochlorine-compounds (DDE, HCB, beta-/gamma -HCH, PCDD/PCDF) and the polybrominated biphenyl ethers concerning the investigations within the project "Sentinel Health Departments" in Baden-Wurttemberg are represented. Additionally results from children from Kazakhstan (Aral-Sea area) and from teachers which are working in PCB polluted schools as well as from a long term investigated test person are reported. Blood concentrations of the following compounds decreased from 1996/97 to 2002/03: the sum of the concentration of PCB 138,153 and 180 decreased from 0.46 microg/L to 0.20 microg/L, DDE from 0.32 microg/L to 0.17 microg/, HCB from 0.20 microg/L to 0.08 microg/L, beta-HCH below the level of detection, I-TEQ NATO to 4.8 pg/g blood fat, TEQ WHO (without PCB) to 5.5 pg/g blood fat, PCB 126 to 18,8,pg/g blood fat and PCB 169 to 12.8 pg/g blood fat. The influence of breast feeding and the gender on the level of the pollution is conspicious. No local correlations were found in Baden-Wurttemberg, but they were found in comparison with the results of Kazakhstan (Aral-Sea area). The difficulty to produce time series while the analyzing pollutants are more and more decreasing, as well as the change of the calculation base of the summation of parameters like I-TEQ NATO to TEQ WHO are discussed.

[Determination of mold concentrations in homes and schools in Baden-Württemberg]. / Bestimmung der Schimmelpilzkonzentration in Wohnungen und Schulen Baden-Württembergs.

So far there have been rather few reliable and comparable data available on indoor pollution with mould. Following the publication of the Federal Environmental Agency and the Health Agency Baden-Württemberg which supports the assessment of mould pollution of indoor air, it seemed advisable to investigate as to how far these criteria can be used for the assessing the mould pollution in daily practice. The results of investigations of 130 homes and 117 classrooms in Baden-Württemberg. will be represented.

[10 years of observation by public health offices in Baden-Württemberg--assessment of human biomonitoring for mercury due to dental amalgam fillings and other sources]. / 10 Jahre Beobachtungsgesundheitsämter in Baden-Württemberg--Beurteilung der Human-Biomonitoring-Untersuchungen bezüglich der Quecksilber-Belastung durch Amalgamfüllungen und andere Quellen.

Since 1992, in Baden-Württemberg, ten-year old children have been surveyed in the project "Sentinel Health Departments" to study their exposure to environmental pollutants and possible health effects. In the four study areas 1200 children have been investigated every year initially, since 1996 every second year. The data for mercury in body fluids are reported here. The decrease in the body burden of mercury as a result of the declining usage of dental amalgam fillings, was been verified. In 1992/93, of all the children who had been surveyed, the 95 percentile for the body burden of mercury was 3.1 microg/l and in 2000/01 1.35 microg/l. Also to be discussed is the reason why mercury-based cosmetic ointments seriously exceed the HBM-II-intervention-value. Because of using these ointments, concentrations of mercury in urine up to 1400 microg/l were found. A study within the project "Sentinel Health Departments" compared the concentrations of mercury in the urine of adults with those in blood and salvia. The results support the opinion that mercury in urine is appropriate for estimating the mercury uptake from dental amalgam fillings. It can be assumed that these results reflect the situation in the entire Federal Republic of Germany. The ten years' experience confirms that the concept of the "Sentinel Health Departments" is excellently suited to obtain data relevant for environmental health of children. Environmental health protection and the essential gathering of data for future health observation in Baden-Württemberg.

[Freud's letters as a historical source]. / Freuds Briefe als historische Quelle.

This article introduces the project of a "concordance of letters to and by Freud". It should make the broadly scattered Freud-correspondence more accessible to the historian. (Since the death of Freud, almost 3200 letters written by him and nearly 1200 letters to him have been published.) At the same time principles of methodology are discussed which have to be observed in using letters as historical source material.

[Freud's letters considered as a historical source]. / Les lettres de Freud en tant que source historique.

Freud's epistolary activity shows him to have been extraordinarily productive in this genre throughout his life. His letters, even more than his works, bear witness to his mastery of style. They have been extensively published in biographical, historical and scientific accounts because of the historical evidence they contain, but they have rarely been the object of a proper methodological analysis. This essay presents the project of a "concordance of the letters to and by Freud" which should facilitate the approach by historians of this extremely scattered epistolary work. 3200 letters of which Freud was the author have already been published since his death, and almost 1,200 letters that were addressed to him. This article also includes a discussion of the methodological principles that must be taken into consideration when using these letters as so many historical sources.
