Vegetables production nowadays depends heavily on new technologies and pesticides usage is almost unavoidable to confront with more insect and disease problems. Farmers have to use agrochemicals including pesticides to produce fresh looking vegetables with no visible rashes or holes caused by pests and diseases. This practice has unfortunately created numerous problems associated with pesticide abuse such as accidental poisoning to man upset of natural environment balance and toxic residues that are hazardous to health in the environment. Therefore constantly monitoring of vegetables for pesticide residues is absolutely needed to protect the consumers. The development of fiber optic sensor measuring device for chemical detection and measurement is part of its application in instrumentation technology. This Fiber optic instrument is much reliable and cost effective compared to other commercial instrument such as spectrophotometer. In this study we have analysed organophosphate pesticide residues using our new locally assembled fiber optic measuring device which could detect color changes in biological reaction such as in enzyme and substrate interaction in the presence of different treatment of pesticide residue concentrations. Preliminary results produced from random vegetable samples taken from several farm at different location in Cameron Highland and wholesale markets at Selayang indicated that this instrument could be used to monitor pesticide residue in vegetables.

Abstract

Vegetables production nowadays depends heavily on new technologies and pesticides usage is almost unavoidable to confront with more insect and disease problems. Farmers have to use agrochemicals including pesticides to produce fresh looking vegetables with no visible rashes or holes caused by pests and diseases. This practice has unfortunately created numerous problems associated with pesticide abuse such as accidental poisoning to man upset of natural environment balance and toxic residues that are hazardous to health in the environment. Therefore constantly monitoring of vegetables for pesticide residues is absolutely needed to protect the consumers. The development of fiber optic sensor measuring device for chemical detection and measurement is part of its application in instrumentation technology. This Fiber optic instrument is much reliable and cost effective compared to other commercial instrument such as spectrophotometer. In this study we have analysed organophosphate pesticide residues using our new locally assembled fiber optic measuring device which could detect color changes in biological reaction such as in enzyme and substrate interaction in the presence of different treatment of pesticide residue concentrations. Preliminary results produced from random vegetable samples taken from several farm at different location in Cameron Highland and wholesale markets at Selayang indicated that this instrument could be used to monitor pesticide residue in vegetables.
