Erythropoiesis, erythropoietin and blood lead levels.

In a previous study EPO values were significantly lower in exposed subjects (PbB > or =30 mcg/dl) than in controls (PbB" 20 mcg/dl). The aim of the study was to verify if high PbB cause the reduction of EPO in connection with the serum concentration of this hormone expected considering the Hct and hemoglobin (Hb) levels. Both in Pb exposed workers and controls blood levels of EPO, PbB, Hb, Hct were measured.

[Acute inorganic lead poisoning in workers employed on building renovation].

Background: Occupationally, there are a number of work processes that constitute a long-term risk as sources of exposure to lead. In these processes the presence of lead is not evident but represents a hidden risk of poisoning.

Objectives: Study of two cases of hidden exposure to lead that were discovered during renovation work on a historical building.
