CORRELATION OF METAL FUME AND VAPOR WITH TOTAL IgE SERUM OF THE BLACKSMITH

Sari

Blacksmith centers which produce agricultural tools, household appliances, carpentry tools, souvenirs, wheels and other vessels are located in the sub District of Daha Utara and Daha Selatan, and District Hulu Sungai Selatan, South Kalimantan Province. The Blacksmiths during their works did not use personal protective equipment, they were always exposed to metal fume and vapor, and other particles such as Diesel Exhaust Particles (DEP), and compounds resulting from the combustion process in a high temperature with results in total IgE  levels. The objective of the investigation  was to assess the correlation between exposure of metal fume and vapor with the total IgE levels.

The study was analytic observational, and cross sectional design conducted in the sub Districts of Daha Utara and Daha Selatan. Measuring of metal fume and vapor, Blood sampling were conducted at Kandangan hospital, and Balai Hiperkes and keselamatan Kerja South Kalimantan Province, respectively. Whereas determination of total IgE levels was carried out at Prodia laboratory Jakarta. The population of studies was  the entire blacksmiths  in sub districts of Daha Utara and Daha Selatan. The sampling procedure was based on purposive sampling predefined by inclusion and exclusion criteria with a sample of 38 units and 38 blacksmiths.

Result were analyzed observational, and cross sectional design using test of Partial Least Square (PLS). The Partial Least Square (PLS) indicated the presence of a significant correlation metal fume, and vapor with the increased of total IgE levels with R²: 0.1569.

In conclusion, This study demonstrates the presence of a positive and significant correlation due to exposure of metal fume and vapor leading to as an increased of total IgE  levels.
