Our bodies are composed of anywhere from 50 to 70 percent water, depending on age. Constant water intake is key to our health, as our bodies lose water throughout the day and night. An adult should normally drink an average of two liters of water daily.
All over the world, national public authorities and research institutes support the work of the World Health Organization (WHO). The German Environment Agency is a WHO Collaborating Centre for research on drinking-water hygiene.
The four Member States (MS) Germany, France, the Netherlands and the United Kingdom of Great Britain and Northern Ireland in 2011 have agreed on collaboration in the harmonization of tests for the hygienic suitability of products in contact with drinking-water. These 4MS-collaboration efforts have evolved successfully and now are termed “4MS-Initiative” (4MSI) in view of extension perspectives.
People are exposed to a wide range of environmental influences, such as noise or pollutants in air and water. These stressors may cause acute or chronic health effects.
