Abstract

The objectives of this study aim to examine the silica dust contamination in working areas of clay brick production and to conduct a health risk assessment of workers in clay brick production factory in Phra Nakhon Si Ayutthaya province. The amount of particulate matter less than 10 micrometers was determined by using personal air sampling pump attached with the workers in 3 areas: raw material preparation area, baking area and post-baking area. The amount of particulate matter (PM) was examined; the total suspended particulate matter and the particulate matter less than 10 micrometer were analyzed by NIOSH methods 7601 with UV-Vis spectrophotometer. The health risk assessment from exposure to respirable dust were determined by risk assessment questionnaire of the U.S. Environmental protection agency. Samples were recruited from the clay brick factory workers in Phra Nakhon Si Ayutthaya province working in preparation area, baking area, or post-baking area. The results revealed that the silica dust concentration in summer was higher than those in rainy season, with the average concentration 0.214 milligram per cubic meter and 0.010 milligram per cubic meter respectively. Regarding health risk assessment, the workers who had worked in the preparation area, both in summer and rainy season, had the highest risk for silica dust exposure compared to the other areas (HQ = 1.91, 0.09) and it will lead to harmful effect mostly on lungs.
