Abstract

Lead exposure in automotive workshop environments is a significant occupational health problem because it can lead to heavy metal accumulation in the blood and affect various organ systems. Workshop workers are at high risk of lead exposure through inhalation and direct contact during vehicle maintenance and repair activities. This study aims to analyze lead levels in blood specimens from automotive workshop workers measured using atomic absorption spectrophotometry. The study used a cross-sectional, observational, analytical design. The research subjects were automotive workshop workers in Banjar Karangsari who met the inclusion criteria. Nine blood samples were taken according to clinical laboratory procedures and measured using an atomic absorption spectrophotometer. The data were analyzed descriptively and analytically to describe the distribution of lead levels and their relationship with respondent characteristics. The results showed that automotive workshop workers had varying blood lead levels, with a tendency to increase in individuals with longer working hours and higher exposure intensity. The findings indicate that there are health risks due to lead exposure in the workshop work environment, which need to be addressed by increasing understanding of occupational safety and health in the informal sector.
