      <subfield code="a">The aim of the present study was to investigate the peak expiratory over a 12 hour period from the start of work on a Monday, to determine if significant reversible airways obstruction occurred in temporal relation to welding. A group of welders and a comparison group of non-welders were studied</subfield>
