      <subfield code="a">To protect the health of workers in industry, and to monitor and control the general environment, it is important to know the concentrations of chemical pollutants in the air. In this study, two porous polymer sorbents (Chromosorb 106 and Tenax TA) were used to sample a number of polar and non-polar organic solvent vapours at concentrations up to twice the OSHA PEL concentration</subfield>
