Relationship between radon exposure and oxidative damage in solar greenhouse workers / 中国职业医学

ABSTRACT

OBJECTIVE: To understand the relationship between radon exposure and oxidative damage in solar greenhouse employees.METHODS: A total of 216 solar greenhouse employees were selected as the study subjects by using cluster random sampling method.Radon concentrations in solar greenhouses were detected by using continuous radon measuring instrument,which were used to estimate the annual radon radiation dose in solar greenhouse employees.T-superoxide dismutase( T-SOD) and malondialdehyde( MDA) levels in venous blood were measured,which were used to present the oxidative damage effects in solar greenhouse employees.RESULTS: The annual radon radiation dose of solar greenhouse employees was 2.00 mSv in 2014.T-SOD activity was( 87.43 ± 15.77) × 10~3 U/L,and MDA concentration was( 4.36 ±0.62) μmol/L.Multivariate logistic regression analysis results showed that after excluding confounding factors such as gender,age,smoking,alcohol drinking,planting length and pesticide exposure score,the higher the radon exposure dose,the higher risk of abnormalities in T-SOD activity and MDA concentration( P < 0.05).CONCLUSION: There is a correlation between radon exposure and oxidative damage effects in solar greenhouse employees.
