Abstract:	The regular medical control established by law in professional lead exposure provides a number of investigations required for workers. Our study has included 97 subjects, occupationally exposed to inorganic lead. Clinical examination, blood tests and urine tests were made to all 97 subjects. The study shows that most subjects have increased values of lead in blood, beyond the limit tolerable organic. Urinary concentration of delta-aminolevulinic acid – an indicator of biological effects, has increased, which correlates with a high absorption of lead. Also, creatinine is not particularly important in lead intoxication, being normal or near normal in most cases. Analysing haemoglobin we have found that only a low rate of subjects had normal levels of haemoglobin, which entitles haemoglobin determination as a marker useful in assessing long-term exposure to inorganic lead. Regarding the clinical symptoms we have found that many subjects have at least one symptom related to intoxication / high absorption of inorganic lead but most of them having no symptoms, although elevated sanguine lead was recorded.
