Abstract

|
|
The objective of this study was to evaluate associations between airborne manganese and blood manganese in a general
population of South Korean adults. The concentrations of airborne manganese in total suspended particulate (TSP) were
calculated from data obtained from ambient air-monitoring stations (AAMSs) located in South Korea. Blood manganese data obtained Korean National Health and Nutrition Examination Survey (KNHANES) using a rolling sampling design involving a complex, stratified, multistage, probability cluster survey of a representative sample of the non-institutionalized civilian population of South Korea. Airborne manganese geometric means was 46.10 ng/㎥, blood manganese geometric means were1.19 ㎍/㎗ for male and 1.40 ㎍/㎗ for female. In multiple linear regression analysis of log transformed blood manganeseas a continuous variable on airborne manganese, after adjusting for covariates including gender, age, job, smoking and drinking status, education level, BMI (body mass index). Airborne manganese was positively associated with blood manganese with statistical significance. The present study confirms that airborne manganese is a possible contributor to the increase of blood manganese in the adult general population.
