Gas station’s operator is one of the jobs are high-risk exposure to lead for a long time. This study aims to determine the association of blood lead levels with incidence of hypertension among the gas station’s operators in Kendari.

The study was conducted at nine stations in Kendari and Forensic and Molecular Biology Laboratory, Faculty of Mathematics and Science, Haluoleo University, Kendari on 16 - 20 December 2016.
