Abstract Second edition of the study analyzed under CIS 01-847. The objective of this thesis work was to examine the working environment and health of electroplating workers, and to establish relationships between the concentration in air of various chemicals, their urinary concentrations and observed nasal injuries. 461 workers employed at 22 electroplating plants using various coating processes were studied. Ambient concentrations of acid vapours as well as of chromium, zinc and nickel were measured, together with the urinary concentrations of these metals among exposed workers. Although the ambient levels were far below the threshold values accepted in Brazil, rhinoscopic examination revealed that 35.5% of workers showed moderate or serious injury of the upper respiratory tract (ischaemia, ulcerations or perforations of the nasal septum) and 40.1% showed signs of initial phases of injury or non-specific injury. These results show that the accepted limits in Brazil are insufficient to ensure adequate protection of workers' health.
