Abstract
A NEED EXISTS IN THE AREA OF HEALTH EFFECTS INSTRUMENTATION TO DEVELOP AN AUTOMATED SAMPLING SYSTEM THAT CAN RECORD THE DRY DEPOSITION OF FINE PARTICLES ( 2.5 ). THE RECENT SYMPOSIUM ON PRECIPITATION SCAVENGING, DRY DEPOSITION AND RESUSPENSION, PUBLISHED IN THE PROCEEDINGS OF THE FOURTH INTERNATIONAL CONFERENCE, SANTA MONICA, CA NOV-DEC '82, HAS CLEARLY ELUCIDATED THREE POINTS: (1) THE PAUCITY OF RELIABLE AND WIDELY APPLICABLE DATA AND THE LARGE RANGE OF VALUES FOR SAME, ESP. DEPOSITION VELOCITIES; (2) THE WIDE ARRAY OF CURRENTLY IN-USE INSTRUMENTATION AND THE LACK OF AGREEMENT AS TO THE BEST TECHNIQUES AND; (3) THE CLEAR NEED FOR BETTER PARTICLE MONITORING INSTRUMENTATION (IN TERMS OF THE SPECIFIC MEASURING TECHNIQUES) EG. RESOLUTION, RESPONSE TIME, ETC. FROM A FEDERAL AGENCY MONITORING STRATGEGY VIEWPOINT, THE REQUIREMENT NECESSITATES THE ACCURATE COLLECTION OF THE SPECIES OF INTEREST (TO ALLOW FOR SUBSEQUENT CHEMICAL ANALYSES) WHICH CONTRIBUTE SUBSTANTIALLY TO THE OVERALL ACIDIFICATION PROCESS AS WELL AS A RELIABLE, COST EFFECTIVE APPROACH. IT MAKES NO SENSE TO DESIGN A NATIONAL MONITORING NETWORK UTILIZING INSTRUMENTATION COSTING $25K/SITE TO REALIZE A FACTOR OF TWO INCREASE IN ACCURACY. THE AUTOMATED DRY DEPOSITION MONITOR PROPOSED HEREIN REPRESENTS THE MODIFICATION OF A TESTED AND PROVEN AUTOMATIC PARTICLE SAMPLING SYSTEM TO PROVIDE FOR THE DETERMINATION OF NITRIC ACID FLUX VALUES AND ULTIMATELY OTHER IMPORTANT ATMOSPHERIC CONSTITUENTS SUCH AS ACID SULFATES AND SULFURIC ACID. THE SYSTEM ALLOWS FOR THE FILTER COLLECTION OF UP TO NINE SAMPLES/STATION, SAMPLING DURATION PROGRAMMABLE FROM 1-24 HR. IN ONE-HOUR INCREMENTS WITH VARIABLE, SELECTED TIME INTERVALS BETWEEN SAMPLES. THE UNIT WILL PROVIDE THE AGENCY WITH SOUND, RELIABLE TECHNOLOGY AT A COST NOT TO EXCEED $5,000/UNIT.
