den stigende anvendelse af vaske - og rengoeringsmidler er en af aarsagerne til forureningen af det naturlige miljoe i almindelighed og vandforureningen i saerdeleshed , en af foelgerne af vaske - og rengoeringsmidlers vandforurening , nemlig skumdannelse i store maengder , begraenser kontakten mellem vand og luft , vanskeliggoer iltningen , udgoer en gene for sejladsen , nedbryder den for vandfloraen noedvendige fotosyntese , har en uhelig indvirkning paa de forskellige faser af spildevandsrensningsprocesserne , skader rensningsanlaeggene for spildevand og udgoer en indirekte mikrobiologisk risiko som foelge af en eventuel viderefoerelse af bakterier og virus ,
Whereas the increasing use of detergents is one of the causes of pollution of the natural environment in general and the pollution of waters in particular; Whereas one of the pollutant effects of detergents on waters, namely the formation of foam in large quantities restricts contact between water and air, renders oxygenation difficult, causes inconvenience to navigation, impairs the photosynthesis necessary to the life of aquatic flora, exercises an unfavourable influence on the various stages of processes for the purification of waste waters, causes damage to waste water purification plants and constitutes an indirect microbiological risk due to the possible tranference of bacteria and viruses;
