In 88% of the workplaces the air humidity is below the standard of 40 to 50%.
A quarter of the workplaces have too high concentrations of fungi and bacteria.
A good clean desk policy at the workplace translates to less dust and microbiological contamination on and around the workplace. 35% of the examined workplaces are below par.
75% of hospitals intend to implement improvements to the indoor climate in the coming 2 years.
The indoor environment is generally more polluted than the outdoor environment; not only with fine dust, but also with other substances. Sources of pollution can be: floor coverings, furniture, building materials, fireplace and kitchen (geyser, cooking and baking). Proper ventilation and airing is important here.
Small particles of particulate matter can be absorbed into the blood via the lungs and thus have an effect elsewhere in the body (heart and blood vessels). In addition, toxicological research shows that particulate matter particles can also enter the brain.
The quality of the indoor environment is also determined by the amount of carbon dioxide in the air, temperature, relative humidity and noise.
A too high temperature restlessness causes the concentration to decrease in girls and boys. To guarantee good air quality, the entire air content of a classroom with 30 pupils must be refreshed every 15 minutes.
