3L PVC Niskin iype water samplers. Samples were drawn in triplicate into cleaned Pyrex glass (phosphate, nitrate) and plastic (silicate) tubes. In June 1987, samples were collected in duplicate in 125 ml polyethylene bottles. All samples were stored frozen (-18 "C) . On the first trip, samples were analyzed @2 by F. Zemlyak (Chemical Oceanography BIO) on the island approximately one week after collection. On subsequent trips, samples were returned to Sidney, B.C. and kept frozen until analysis approximately 2 months later.
3. ANALYTICAL METHODS 3.1 Chlorinated Hydrocarbons 3.1.1 Materials Solvents used were pesticide grade, distilled in glass (hexane and pentane supplied by Burdick and Jackson; dichloromethane and acetone supplied by BDH Omnisolve; methanol supplied by Caledon) . Acetonitrile (Burdick and Jackson) was redistilled through a 90 cm burle packed column at 5 mL min-I before use. Diethylether (Caledon) was fractionally redistilled before use and stored in the refrigerator. A solvent blank was determined for each new solvent by rotary evaporation of the amount used in procedure to 100 p1 and analysis of a 1 pL injection into the GC/ECS using standard conditions. Solvents were used only if blank gas chromatograms were free of interfering peaks. Florisil (Baker, 60 - 100 mesh) was washed with acetone and hexane, dried at 80°C for 48 h and then activated at 500°C for 24 h. After cooling, the florisil was deactivated with 3% (by weight) distilled water, and allowed to stand 48 h in a stoppered flask before use. Florisil (Baker, 60 - 100 mesh) used fqr samples from the third trip was prepared by washing with acetone and hexane and drying at 80°C for 48 h. The florisil was then activated at 600°C for 6 h, slowly cooled to 100°C, transferred while warm to a nitrogen flushed flask, and then cooled in the stoppered flask. After cooling, the florisil was deactivated with distilled water (1.2% by weight) and allowed to equilibrate for 48 h. Glassware was washed in laboratory detergent, rinsed with tap water, then distilled water, air dried, and baked overnight at 340°C in a forced air oven. After baking glassware was wrapped in aluminum foil for storage. Metal and teflon items were washed with laboratory detergent, rinsed with distilled water, dried with acetone, and then cleaned with dichloromethane and hexane immediately before use.
