Comprehensive GC-MS analyses of the volatile oil from leaves of Ocimum canum Sims revealed the occurrence of eugenol as the major constituent, in addition to 28 other compounds. Since methyl cinnamate, camphor, citral and linalol chemotypes of 0. canum have previously been found, a new type is now b
The composition of the volatile leaf oil of Pinus ponderosa Dougl. Ex. P. Lawson was re-examined by fused silica capillary gas chromatography-ion trap mass spectroscopy. The leaf oil from Washington was high in ar-and bpinenes (9.1% and 37.9%), car-3-ene (19-3%), a-terpineol (6.2%). myrcene (4.1%) a

## Abstract **BACKGROUND:** An emerging innovation for the treatment of polluted air consists in using a liquidโsolid biphasic system, in which the sequestering phase contains inert polymer beads. The different polymers tested here for this purpose were; Hytrel^ยฎ^ G3548L, Hytrel^ยฎ^ G4078W, styrene
