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.
