Traduction en anglais : Lead in drinking water. On determining a new limit value and the problems of lead tubes.
The problem of lead in drinking water with regard to sensitive groups of the general population (e.g. unborn, babies that are not breast-fed, infants and children) is discussed.
In respect of children in nurseries, the question regarding the relation of blood-lead levels to neurobehavioural deficits due to lead as well as a theoretical « tolerable » daily intake of lead is discussed.
A provisional daily intake of approx. 1.2-1.3 mug Pb/kg body weight for children and pregnant women is proposed.
For non-pregnant adults a double to three times higher intake may be tolerated (base: high blood pressure).
These doses are well three times below the still recognised Provisional Tolerable Weekly Intake of lead (PTWI-values, WHO), when related to daily intake.
