|
|
Objectives: This study was conducted in order to evaluate personal and area exposure to airborne total dust and endotoxin during harvest and planting tasks at cucumber, yellow melon and potato farms
Materials and Methods: Total dust was measured with NIOSH method 0500. Endotoxin were measured using a 37 mm glass fiber filter which was connected to an air pump calibrated to 2 LPM, and then analyzed with a Turbidmetric kinetic method.
Results: The average(arithmetic mean) concentrations of total dust in the personal samples were 0.10- 3.81 ㎎/㎥ for cucumbers, 0.21-1.19 ㎎/㎥ for yellow melon, and 0.08- 2.72 ㎎/㎥ for potato. There was a significant difference in the harvest task among the three farm types(p=0.019 of personal sample, p=0.048 of area sample), in which the air concentration for potatoes was higher than with cucumbers and yellow melons.
Conclusions: It was found that potatoes(planting and harvest) should be considered the first priority for studying and reducing total dust exposure.
