Presentamos un estudio de higiene ocupacional llevado a cabo en una empresa de metal duro, en la que para conocer la prevalencia de alteraciones respiratorias por exposición a polvo de metal duro, se realizaron mediciones de los niveles ambientales de cobalto y se evaluó clínica y funcionalmente y con pruebas de provocación a 65 de sus trabajadores (72% del total). Encontramos asma ocupacional en cuatro (6,1%), alteraciones radiológicas con profusión ≥ 1/1 en tres casos, sin correlación clínico-funcional en ninguno de ellos y síndrome restrictivo con difusión de monóxido de carbono disminuida en un trabajador asintomático y con radiografía de tórax normal. Por otra parte, siete trabajadores presentaron obstrucción al flujo aéreo, atribuible al hábito tabáquico en seis de ellos y a la presencia de asma bronquial no profesional en el séptimo.

We report an occupational hygienic study carried out in a hard metal factory. The purpose was to evaluate the prevalence of respiratory disorders associated with hard metal expossure. We measured environmental cobalt levels and obtained clinical histories, functional respiratory tests and bronchial challenge tests in 65 workers (72% of the total work force). We found occupational asthma in 4 (6,1%). Three workers showed abnormal radiographs with profusion ≥ 1/1 without clinical-functional correlation. One asymptomatic worker with normal X-ray showed a restrictive syndrome and decreased carbon monoxide diffusion. On the other hand, 7 workers showed airways obstruction related to smoking habit in 6 of them and to non occupational bronchial asthma in the other one.
