Laboratory Support and Methodology Studies (Task 6) Contact: F. Tomassini Through the coordinated efforts of the Central and Dorset Laboratories, the Laboratory Services Branch (LSB) continued to support the various APIOS programs. A summary of the total test load for the program is shown in Figure 22. The 1989/90 fiscal year was a productive year and the highlights are: A. INTERLABORATORY COMPARISON ANALYSIS a.

Eulerian Model Evaluation Field Study (EMEFS) 2. Precipitation - The LSB received 10 submissions (100 samples) for major ions, nutrients, physical parameters analyses in addition to a single submission for low level anions (chloride, nitrate and sulphate analyses). (Workload 2251 tests). Air Filters - In January 1990, a new study was initiated on air sampUng filters of nylon. Teflon and Whatman 41. The first submission of 72 filters was analyzed for ammonium, nitrate, sulphiu- dioxide 600 .Thousands. 80/81 81/82 82/83 83/84 84/85 85/86 86/87 87/88 88/89 89/90 Dorset lab only ^S Total APIOS tests Figure 22 Laboratory Workload Summary 55.
