The present descriptive and prospective study was conducted in "Tasajeras" Zeolite Mine-Plant, located in the municipality of Ranchuelo, province of Villa Clara, from September, 1998, to September, 1999, aimed at evaluating the ventilatory function in a group of workers exposed to zeolite dust. 37 workers with 2 or more years in the center answered a questionnarie. 2 sperimotric studies were carried out with a one-year interval. The information was analyzed and the results were the following: the number of patients undergoing the pathological ventilatory functional test was increased from 16, in 1998, to 24, in 1999. 64.8% of those with spirometric affectation have been exposed between 6 and 10 years to zeolite dust and 58.3% are smokers. The obstructive spirographic pattern prevailed (56.8%). A reduction of the forced expiratory flow to 25% (Vmax 25/H/L/T) was observed in 62.1% of the studied individuals
