This work was conducted in an iron and steel factory (Menoufiya governorate) to study auditory and respiratory disorders which may arise among workers in that industry.This study included an exposed group of iron and steel workers (106)br>who accepted participating in the study and a control non exposed group (100) from the worker s relatives. Both groups were matched for age, sex, residence, marital status, income and educational level.The exposed group and controls were interviewed using a predesigned questionnaire about respiratory and auditory symptoms. Also, they were examined generally and locally for chest and ears. Spirometric measurements as well as Audiometry were carried out for both exposed group and controls aiming to assess pulmonary functions and hearing thresholds; respectively.Environmental studies were done by NRC periodically via air sampling (using gas analyzer from the respiratory zone of the workers),assessment of noise at the level of workers ears (using sound level meter)and measuring heat levels (using portable heat stress monitor).The following results were obtained:The environmental measurements of the exposed group were lower than permissible exposure limits (PEL) for CO, NOx and FeO, but noise level was higher than the PEL.
