Abstract:
Objective To analyze the effect of smoking behavior on the exposure levels of lead and cadmium in outdoor traffic policemen, and to provide a scientific basis for controlling the exposure levels of lead and cadmium. Methods A total of 115 male outdoor traffic police officers from a traffic police brigade in Wuhan were taken as the subjects in this study. Their frequencies and years of smoking were collected, and the concentrations of lead and cadmium in their blood and urine were detected. Linear regression model was used to analyze the correlation between smoking frequency, smoking years, and cumulative smoking amount (smoking frequency × smoking years) and the concentration levels of blood lead, urine lead, blood cadmium and urine cadmium. Results The concentrations of blood lead, blood cadmium and urine cadmium in the smoking group were significantly higher than those in the non-smoking group (P<0.05), but there was no significant difference in urine lead concentration (P<0.05). In addition to urinary lead, the concentrations of blood lead, blood cadmium and urine cadmium were significantly positively correlated with smoking frequency, smoking years, and cumulative smoking amount (P<0.05) , and showed a significant upward trend with the increase of smoking frequency, smoking years and cumulative smoking amount (Ptrend< 0.05). Conclusion Smoking is a risk factor of lead and cadmium exposure in outdoor traffic policemen. Quitting smoking and controlling smoking may be effective ways to control exposure levels of lead and cadmium.
