But also from European countries, including Germany, permanent harmful products to hit the market. Some examples to show where the problem lies mainly:
Dataloggers measure the room climate
– The climatology is one of the most difficult areas of science. Air, temperature and electric climate influence each other more or less – and these factors are in turn influenced indoors of building materials, construction and electrical installation. Although cooperating the individual components of indoor climate, it will be discussed for better presentation separately. Now read which components affect our indoor climate.
film strip system
The laboratory team of the Environmental Mycology in Berlin is always good for an innovation. Under the direction of Dr. Christoph Trautmann and Dr. Ingrid Dill the mold experts developed a test strip system for mold detection handling surface contact samples. Their motivation is obvious: The more accurate the building biologist working at the sampling, the safer is the analysis result. Unprofessional sampling, however, prepare the laboratory team a considerable overhead. Continue reading
formaldehyde in an office
Six months ago Anne Hopf took up her new job in a public authority in North-Hesse/Germany. She is sitting in an office space of twenty square meters, together with a colleague.

The temptation is great. A young family in northern Bavaria discovered a beautiful home in a great location with the right plan at an affordable price. The prefabricated wooden house was built in the seventies. Manuela Brenner has read of problems with these types of houses and caused a dust sample before buying. Laboratory analysis gives a value of 1 mg of pentachlorophenol (PCP) per kilogram of house dust. How is the health risk to be assessed? If the family to buy the house?
daylight in the workplace
Daylight in the workplace promotes the health and performance of employees. Scientific studies have shown a number of advantages for the physical and mental well-being: control of day and night rhythm, strengthening it immune system, release of serotonin, vitamin A and D synthesis, protection of the eyes, and others. In technical terms, the boundary conditions at the workplace are called hygiene factors. Reason enough to become familiar with the most important parameters for the lighting of work.
health problems disappeared after dismantling of a mobile phone base station
The German journal “Environmental Medicine Society” published in issue 12/2014 a mobile study of a Japanese research team. 107 residents of a skyscraper in Okinawa participated in 2009 in a clinical study in conjunction with a questionnaire. The response rate to the questionnaire was 88%.
In the eight-storey high-rise building was attached in 1998 a mobile antenna in the range of 800 MHz. In March 2008, two additional transmission facilities were put into operation. They were broadcasting in the range of two GHz. The first health examination was carried out in January 2009, i.e. eleven months after the start of broadcasting in the 2-GHz-conditioning and eleven years after the start of the 800-MHz antenna. The second study was conducted in November 2009. At this time, both systems were already five months and nine months no longer in operation. Continue reading
A family from the Bavarian Forest (Germany) has made unpleasant experiences with the longevity of formaldehyde. Two years ago they bought a prefabricated house built in 1975.
