This technique has been applied to the concentration of organochlorine and organophosphorus insecticide [7,8] and various ethers, glycols amines, nitriles, hydrocarbons, and chlorinated hydrocarbons. Although this work was concerned with drinking water, it is a useful technique which may have application in seawater analysis. Cellulose acetate [9], ethyl cellulose acetate [6], and crosslinked polyethyleneinine [8] have been used as semi-permeable membranes.

Macroreticular resins, particularly the Amberlite XAD series, have been used extensively to isolate and concentrate trace organic compounds from drinking water (1-8). We have previously reported the use of an XAD cartridge for this purpose and have evaluated the system for the analysis of organophosphorus pesticides (OPs) (4), polynuclear aromatic hydrocarbons (PAHs) (5), phosphate triesters (TAAPs) (6), or-... 

The RMBC assessed its regional public-health priorities and developed the following nine demonstration projects on the basis of the needs of the community possible correlation of exposure to arsenic in drinking water and type 2 diabetes, a spot blood metals-analysis feasibility study, health-clinic samples for chemical-terrorism baselines, of relationship between urine arsenic and metal concentrations and drinking-water exposure, assessment of exposure to VOCs from subsurface volatilization, cotinine concentrations associated with environmental tobacco smoke, assessment of exposure to mercury from ingestion of fish, analysis of radionuclides in urine, and biomonitoring of organophosphorus pesticides in urine (Utah Department of Health 2006).

The use of a direct event for indication of analyte presence and concentration allow this detection technique to be used in real time. This, together with the broad nature of the detection protocols, makes the sensor system ideally suited for application as an early warning device. The surfaces can be used for repeated assays throughout their frmctional lifetimes and are exceptionally sensitive, with limits of detection for organophosphorus compounds below the current safe drinking water standards (75, 14, 17, 18, 44). In addition to detection of a variety of analytes in solution (70, 12-18), these enzyme based surfaces have been applied to the detection of GB vapor as well as gaseous carbon dioxide 16, 18).

Other stationary phases such as the SPD-608 and the DB-210 are recommended in Method 8141A. The cyanopropyl phase (DB-1701), however, can cause elevated baselines when used with the NPD, because of the nitrogen it contains. A normal calibration range for the organophosphorus pesticide standards is 200-1000 ng/mL. Method detection limits are in the low parts per billion for water and soil samples. USEPA Method 507 uses capillary GCNPD to determine the organophosphorus pesticides in drinking water (98).
