An investigation was carried out on 927 workers. A high rate of allergic disease was reported, especially at the respiratory system. 11 to 12 year long occupational ages are the most vulnerable ages with a highest rate of positive reaction to cotton dusty allergen. Mean value of pulmonary air flow volume decreased among all age groups in comparing with normal value.

Our research was carried out on 133 occupational carbon monoxide exposed workers in a metallurgical factory. The results showed that carbon monoxide concentration in some working places was higher than the allowance limit from 1.4 to 5.3 times. 77.2% indoor environment was polluted by substances coming from factory. This pollution had influenced on the health of 35.3% of workers (influence on nervous, circulatory, respiratory, digestive systems and anemia,..) 16.5% of the cases suffered from occupational carbon monoxide chronic clinical poisoning. The occupational acute carbon monoxide poisoned anamnesis at the factory was 7.3%.

The investigation was done in 74 occupational carbon monoxide exposed workers in a coke factory. The result showed that carbon monoxide concentration in some work places was higher than the allowable limit from 1,2 to 5 times. 70,3% workers' indoor environment was polluted by substances coming from factory. These pollution had influence on the health of 47,2% workers (influence on nervous, circulatory, respiratory, digestive systems and anemia etc.). 1,4% of the cases suffered from occupational carbon monoxide chronic clinical poisoning.

A survey on working environment at 35 facilities discovered some types of dusts, harmful factors such as the noise at high level in some working places (94-100 dBA), tiny dusts, over standard petrol gas. 14/760 workers were examined periodically had tetraetyl lead level in urine during 24 hours. Among 54 cases of lead comtanination, the clinical symptoms of arterial blood pressure - pulse accounted for 42,5%; headache, in somia, much sweating on arms and legs were high, 60 cases suffered from occupational skin gray.
