Background:
The chemical concentrations in the atmosphere from air quality monitoring stations of Map Ta Phut Industrial Estate, Thailand.
Objective:
This study aimed to compare blood levels of malondialdehyde (MDA) according to risk factors among participants in four occupations in the MTP-IE, Rayong Province.
Methods:
Interviews were conducted; urine samples were collected to analyze S phenyl mercapturic acid, 1,2 dihydroxy-4-(N acetyl) butane, and 1,2 dichloroethane twice on weekdays and weekends; blood samples were collected to analyze MDA in a sample of four occupational groups: traffic police, outdoor food vendors, public transport drivers, and fishery workers.
Results:
The study found that factors causing significantly different levels of MDA (p < 0.05) were 1,2 dichloroethane (mg/L) (weekend) (p < 0.006), BMI (kg/m2) (p < 0.028), occupation (p < 0.001), personal hygiene care (per week) (p < 0.001), and at-work physical activity (p < 0.021).
Conclusions:
To reduce blood MDA levels, it is recommended to monitor the health of workers in high-risk areas by examining MDA levels in the blood to assess the risk of cancer from exposure to 1,2 dichloroethane and to encourage workers to address personal hygiene.
