Resumen |
Recalls the trends in pneumoconiosis control in many countries. The article gives the maximum permissible dust levels in force in several countries (Italy, Australia, Belgium, France, Germany (Fed.Rep.), Japan, Republic of South Africa, Sweden, USSR, USA and Yugoslavia), which are compared in several tables. Description of an experiment carried out in Italy by the National Accident Prevention Institute (ENPI) in 120 undertakings presenting a silicosis hazard, in 60 of which dust levels exceeded the TLV fixed in USA by the American Conference of Governmental Industrial Hygienists (ACGIH). Results of clinical and radiological examinations on 5,164 workers in metal trades, 46 of whom showed symptoms of nodular silicosis and 459 had suspected silicosis. Most of the silicotic workers were employed in an environment where the silicosis hazard exceeded the ACGIH TLV. Although findings obtained from such a small sample could not be extrapolated, the author believes that a correlation exists between the fact that the hazard index has been exceeded and its biological evidence. |
