Prototype Micro Sensors For The Detection Of Pesticide Residues On Blueberries, Guang Chen

Electronic Theses and Dissertations

The widespread use of pesticides on commercial food crops can result in short and long term health problems for both f m workers and consumers as well as serious impacts on the environment. Consequently, there is an increasing need to develop low cost portable detection systems that can be used to screen for pesticide residues on food products. Since phosmet (C1 IH12N04PS2) is one of the most commonly used organophosphorous pesticides within the state of Maine, it is selected as the target pesticide to detect in this thesis. Two sensing techniques were investigated. One is the quartz crystal microbalance (QCM), …
