The amount of lead entering the human body is influenced by several factors: the physicochemical properties of lead compounds, specific host factors such as age, sex, physical conditions, etc. In humans the main routes of lead intake are the respiratory tract (RT) and the gastrointestinal tract (GIT). This paper states "an imponderable aliquot of lead can enter the GIT from unusual sources" and looks at the quantities of lead that can be found in a liquid following leaching from crystal recipients. It concludes that "crystal recipients represent only occasional sources of leaching when, as stressed in the article earlier, they are used incorrectly. Consequently, all primary prevention should be aimed at using these containers in the correct way.
