title: Altered levels of urinary prostanoids in lead-exposed workers.
abstract: This paper describes the alteration of the urinary excretion of prostanoids in workers occupationally exposed to lead. For this purpose, the following groups were studied: Group 1 (n = 62): controls; Group 2 (n = 29): risk group; and Group 3 (n = 69): exposed group. Urine samples were collected for prostanoid analysis and lead blood levels were analyzed. Our results demonstrate that urinary excretion of prostanoids is already altered even at levels of lead in blood = 200 micrograms/l. Owing to their sensitivity, urinary prostanoids could be useful markers of early renal changes associated with lead exposure. However, underlying mechanisms should be elucidated and the health significance of such changes should be assessed before any conclusion is drawn.
