      <subfield code="a">The environmental findings of a combined occupational hygiene and medical study of exposure to airborne contaminants from a welding process are reported. It is clear that occasional sampling of a few welders in a group may give little indication of long-term individual or group exposure. There is need for a simple, easily worn and reliable sampling package for measuring concentrations of gases and fume in the breathing zone of welders</subfield>
