Knowledge about gender-relate exposures is rare. Therefore, based on a patient collective in environmental medicine gender specific aspects of surrounding exposures were investigated. Questionnaire data of 656 women and 501 men, who have to be affected by environment-related health disorders were retrospectively analyzed. Gender specific differences and risk factors were determined by frequency distributions. Significant differences between women and men could be shown for exposures at home and workplace, for behavioral risk factors, and for health effects.

Since 1987, in Germany advisory centers for environmental medicine were founded. In the present study the relevance of indoor air problems in a patient collective in environmental medicine was investigated. Questionnaire data of 772 patients, who consulted the former Consulting Center of Environmental Medicine (CEM) of the Medical Institute of Environmental Hygiene at the Heinrich Heine-University Duesseldorf because of the suspicion of environment-related health disorders, were retrospectively examined regarding exposures and health effects.

There are several factors that affect the hygiene in the surgical operating theatres. The HVACairside system plays an important role to maintain the adequate hygiene level in the operatingtheatres. The present paper displays comparisons between different HVAC airside designs toassess their impact on the surgery staff and patient health and comfort. The present workutilizes a numerical modelling technique to predict local flow field characteristics, heattransfer and air distribution profiles.

The relationship between psychosocial characteristics and sick building syndrome(SBS) was explored among 348 employees occupying two buildings engaged in thepublic sector in Pretoria, South Africa. One building was characterized as sick(building B), whilst the other was not a known sick building (building A).

Correlation analysis of subjective responses of tropically acclimatized office workers in a fieldstudy conducted over nine continuous weeks using a 2 2 balanced design with temperatureand fresh air ventilation rates as control variables revealed that several related SBS symptomsare highly correlated. Thermal comfort and acceptability of air quality exhibit a strongcorrelation, whereas perceived indoor environmental variables have poor correlations amongthemselves. Principal component analysis further improved measures to variability bycombining coherent variables into six factors.

In January 2002, a new European project named HOPE (Health Optimization Protocol forEnergy-efficient Buildings) started with 14 participants from nine European countries. Thefinal goal of the project is to provide the means to increase the number of energy-efficientbuildings, i.e. buildings that are at the same time healthy and low energy users. Reducingenergy use by buildings also reduces CO2 emissions from primary energy used for ventilation,heating and humidity control.

Current remedial actions to buildings with indoor-environmental problems do not seem to decrease efficiently residents’ symptoms typical of the sick building syndrome (SBS). Apart from potentially unsuccessful renovations (cases), the cause could be that

After moving into a new office building, employees complained about irritation of eyes, sorethroat and unspecific symptoms. A working group was appointed to investigate indoor airpollution.Air samples and floor dust samples for the analysis of organic compounds were collected inoffice rooms. Within 8 months, several measurement campaigns were conducted to assess thetrends of the concentrations of air pollutants.

A sample of 269 workers, selected randomly from 1600 employees of a sealed 42-storeyoffice building of a major bank in Rio de Janeiro, Brazil, responded to the standard RoyalSociety of Health Advisory Group questionnaire about Sick Building Syndrome.Upper airways respiratory symptoms occupied a prominent position, with a prevalence ofaround 40%, whereas the lower airways manifestations frequencies were below 20%.

In order to determine the a etiological factor of Sick House Syndrome (SHS), indoor airquality of 35 houses in Miyagi prefecture of Japan, where occupants are suspected ofsuffering from SHS, had been investigated during the summers in 2000-2002. Theinvestigation included the measurement of indoor chemical substance concentration and aquestionnaire regarding residential environment and subjective symptoms.As a result, the formaldehyde concentrations in 71% of all houses exceeded the guideline ofJapan.
