Abstract: The study was analytic observational, and cross sectional design conducted in the sub Districts of Daha Utara and Daha Selatan. Blood sampling, measuring of CO, SO2, NO2 gases, metal fume and vapor, and Forced Vital Capacity (FVC), Forced Expiratory Volume1 (FEV1) and Mixed (FVC+FEV1) were conducted at Kandangan hospital, and Balai Hiperkes and keselamatan Kerja South Kalimantan Province, respectively. 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 Pearson correlation test, logistic regression, and test of Partial Least Square (PLS). Pearson correlation test showed a significant correlation exists due to exposure of CO, NO2, and metal fume. This was indicated by the FVC with p:< 0.05, although SO2 and metal fume was not significant. The results of logistic regression showed: (1) a significant correlation due to exposure of CO, SO2, NO2, metal fume, and vapor indicated by the FEV1 with p:< 0.05; (2) a significant correlation due to exposure of CO, SO2, NO2, metal fume, and vapor with the mixed disfunction (FVC +FEV1) with p:< 0.05. In conclusion, This study demonstrates the presence of a positive and significant correlation due to exposure of CO, NO2, and vapor leading to FVC, FEV1, and mixed type. Exposure of SO2 and metal fume gives positive and significant correlation with the occurrence of the FEV1, however there is not significant correlation with the occurence of FVC.

Keywords: CO, SO2, NO2, metal fume and vapor exposure, restrictive(FVC), obstructive (FEV1) and mixed.
