ABSTRACT

Objectives: The aim of this research was to detect the effects of the steel-welding inert-gas protected exposure in the pulmonary function measuring the activity’s influence, nicotinism habits and seniority. Introduction: In the last years many studies have been carried out concerning steel welding fumes effects on welder’s health. The respiratory function has been one of the many studied effects, although the results have not been consistent. Material and methods: The study was carried out in a male-welder population. The subjects were employees in the heavy-machine spare-parts manufacture in Monterrey, Nuevo Leon, Mexico. The pulmonary function was evaluated by a MasterLab-Body; Erich Jaeger GmbH&CoKG 1992, 1993; following the acceptability and the reproducibiliness criterion acknowledged by the American Thoracic Society. Result: The bidirectional analysis showed a significative effect in nicotinism contrary to exposure antecedents. The comparison of parameters of pulmonary function between groups of welders against the standard showed significative differences. Conclusions: The result of this study does not corres-pond with the ones developed in other countries, where the labour-exposure effects in pulmonary function impairment seems not evident. The decrement of the pulmonary function registered in the welders studied is probably due to the noxious substances in the respiratory tract.
