Elevated blood lead in a population near a lead smelter in Kosovo, Yugoslavia.

A survey of residents of a community surrounding a lead smelter has revealed an alarming incidence of elevated blood lead and erythrocyte protoporphyrin concentrations. In particular, children who were less than 3 yr of age were severely affected. Of those children tested in December, 1980, 35% had blood lead concentrations between 50-69 microgram/dl, while an additional 12% had concentrations greater than or equal to 70 microgram/dl, and are, therefore, at risk for severe neurological sequelae.

The paper deals with a patient with secondary erythrocytosis as concequence of renal carcinoma. Although the diagnosis was clear, it was confirmed by bone marrow culture. The colony-forming results were in accordance with secondary erythrocytosis. This case is a good example of high sensitivity of the above mentioned method. The second reason for this paper was the assertion that bone marrow culture can be used as a sensitive follow-up method.
