The second sampling system, consisting of a particulate filter and several XAD traps, was used for the collection of particulate and semi-volatile compounds.
5] For the collection of filter and XAD samples for chemical analysis, a large supplemental secondary dilution tunnel that permitted the use of an 203x254-mm (8x10-inch) Zefuor[TM] filter followed by four 10.

The tiny particles of the Fine XAD
Sorbent Coating adhere to materials, such as glass, plastic, metal, and fabric because of the molecular attractive forces between the particles and the molecules--no adhesive substance is necessary other than the coating itself.

The adsorption of direct red by banana peel and the adsorption of phenol by activated palm seed coat and XAD
resin show similar behavior [40, 6, 41].

For the mutagenicity tests, the XAD
extracts were dissolved in dimethyl sulfoxide.
20 ml of pooled urines from each group was passed through XAD
column to concentrate weakly anionic compounds (Yamasaki and Ames, 1977).
