Abstract: | BACKGROUND: Shooting with lead-containing ammunition in firing ranges is a well-known source of lead exposure in adults, and police officers may be at risk of lead intoxication. More stringent national lead regulations stimulated a survey of blood lead (PbB) in Swedish police officers with regular shooting habits. METHODS: Police officers considered as the most active shooters on and/or off duty responded to a questionnaire about health, lifestyle, shooting habits, and potential lead exposure. Blood samples were collected and analyzed for PbB and a multivariate regression analysis was performed. RESULTS: The mean PbB in male officers (n = 75) was 0.24 mumol/L (5.0 micrograms/dL); range 0.05-0.88 mumol/L (1.0-18.2 micrograms/dL), and in female officers (n = 3) it was even lower (0.18 mumol/L; 3.7 micrograms/dL). For both sexes combined, a positive correlation (r = 0.55; P < 0.001) of PbB with the number of bullets annually fired both on and off duty was observed, and this finding remained in a multiple regression analysis including age, smoking habits, and latency from last shooting exercise. DISCUSSION: In conclusion, occupational and recreational lead exposure from firing ranges still seems to be a source of lead exposure in Swedish police officers, but it no longer appears to be a health risk. Lead-free communication and well-ventilated indoor firing ranges may have been decisive for this encouraging finding. |
