ANNUALLY THE UNITED STATESAPPLIES 1.2 BILLION POUNDS OF PESTICIDES 57% OF WHICH ARE HERBICIDES. ESTIMATES BY THE USDA INDICATE THAT ROUGHLY 50 MILLION AMERICANS MAY USE DRINKING WATER THAT IS POTENTIALLY CONTAMINATED WITH PESTICIDES. THOUGH PESTICIDES ARE PERTINENT FOR FOOD SECURITY AND PRODUCTION MIGRATION TO NON-TARGET CROPS ORGANISMS AND ECOSYSTEMS HAVE BEEN CONFIRMED. THOUGH THERE IS MUCH MORE TO BE UNDERSTOOD ABOUT THE ENVIRONMENTAL AND HEALTH RISKS OF NON-TARGET PESTICIDE EXPOSURE STUDIES HAVE SHOWN THAT EXPOSURE EVEN UNDER THE EPA-DESIGNATED TOLERANCE LEVELS MAY LEAD TO A VARIETY OF HEALTH RISKS INCLUDING LOW BIRTHWEIGHT ABNORMAL BRAIN DEVELOPMENT AND INCREASED CANCER.IN ORDER TO BETTER UNDERSTAND PESTICIDE EXPOSURE SENSING DEVICES MUST BE DEVELOPED TO MAP PESTICIDES REGIONALLY. SENSING DEVICES WILL BE MADE FOR EACH PESTICIDE THAT IS OF CONCERN IN THE MIDWEST USING LOW-COST MATERIALS. MULTIPLE SENSORS CAN BE USED SIMULTANEOUSLY TO DETECT A VARIETY OF PESTICIDES. THESE SENSORS CAN BE COMBINED INTO AN ALL-IN-ONE DEVICE. AFTER MANY VALIDATION METHODS THE DEVICE WILL BE USED IN REAL-LIFE APPLICATIONS INCLUDING SURFACE WATERS AGRICULTURAL FIELDS AND RIVERS.MONITORING THESE SYSTEMS ALLOWS FOR THE DEVELOPMENT OF ACCURATE PESTICIDE MAPPING. THE DEVELOPED SENSOR CAN BE USED IN VARIOUS LOCATIONS AND BYPASSES THE NEED TO TAKE SAMPLES BACK TO A HIGH TECH LAB. THIS ALLOWS FOR FARMERS TO OPERATE AN EASY-TO-USE DEVICE FOR MONITORING THEIR FIELDS. THE DEVICE CAN BE USED BY OTHER PERSONNEL TO MONITOR SURFACE WATERS AND RIVERS. THROUGH THIS ACCUMULATION OF KNOWLEDGE POLICYMAKERS WILL SEE A CLEARER PICTURE REGARDING THE MIGRATION OF PESTICIDES TO UNINTENDED FIELDS ORGANISMS AND ECOSYSTEMS. POLICIES CAN THEN BE ENACTED THAT PROMOTE AGRICULTURAL SUSTAINABILITY REDUCE PESTICIDE POLLUTION AND REDUCE THE RISK THAT PESTICIDES POSE TO HUMANS.
