[Risk of abnormal absorption of lead in glass decoration workers]

Following the observation of an abnormal lead absorption (PbB 72 micrograms/100 ml) in a young female glass decorator on a routine laboratory test, blood lead levels were measured in glass decorators of the entire area of the Local Health Unit of Treviso (Northern Italy). Abnormal lead absorption was found in a large number of glass workers, the source of exposure being the high content of inorganic lead in the "low-melting" paints that were used (brush and spray painting). Most of the exposed workers were females of fertile age, for whom even a moderate exposure to inorganic lead may constitute a risk during pregnancy. Attempts to reduce lead exposure levels by means of a health education programme and environmental improvements at the workplace were unsuccessful. In conclusion, a reduction in lead absorption in female glass decoration workers can only be achieved by using "low-melting" paints with a lower lead content.
