, Description:FIELD OF THE INVENTION:
The present invention relates to pesticide in fresh fruits and vegetable available in market. The present invention more particularly relates to a IOT based solution for monitoring of pollution through pesticide in fresh fruits and vegetable available in market .
BACKGROUND OF THE INVENTION:
Pesticides are chemical substances applied to crops at various stages of cultivation and during the post-harvest storage of crops. The use of pesticides is intended to prevent the destruction of food crops by controlling agricultural pests or unwanted plants and to improve plant quality. Pesticide use in commercial agriculture has led to an increase in farm productivity. Despite the wide ranging benefits of using pesticides in agriculture, several incorrect applications can result in high and undesirable levels of the compounds in the produce that reaches consumers. These include inappropriate selection of pesticides used on foodstuffs, over use of pesticides and harvesting the crops before the residues have washed off after application. Monitoring of pesticides in fruit and vegetable samples has increased in the last years since most countries have established maximum residue level (MRL) for pesticides in food products.

With the gradual advance of urbanization construction, the procurements of vegetables and fruits are most in markets and supermarkets. However, these procurement locations almost have no pesticide residues detection devices. Gas chromatography (GC), or combinations (GC-MS or LC-MS/MS) are traditional analytical techniques for identification and quantity determination of pesticides residues. Although these methods offer quantitative analysis with sensitivity and selectivity, they are slow, expensive, laborious and not convenient to popularize and promote. Moreover, they don’t have the ability of information sharing and remote control. Therefore, they are not suitable for rapid detection and agricultural products traceability. Biosensors account for an easy method to determine pesticides in environmental and food matrices. The use of biosensors as screening devices is cost effective and decreases the number of samples to be analyzed by traditional analytical techniques mentioned above. With the explosive growth of smart phones, wireless technologies and sensor technologies have become a fundamental tool for everyday life around the world.
International Journal of Scientific & Engineering Research Volume 10, Issue 3, March-2019 761. The IoT we used in this pesticide residues detection system based on the pesticides detection . Due to the above, the purpose of this investigation is to design a system for pesticide residues detection and agricultural products traceability. This system can be used in supermarkets, markets and plantations. Moreover, this system also can be used in the areas of purchasing, storage and transportation, and in house.
Increase in the population of India, results in higher demand for food as well as decrease in land for farming. Hence to fulfil the increased demand, food is adulterated to get more quantity in short period of time. Moreover, pesticides in crops are using above the legal maximum residue limit by farmers to gain more profit in lesser time. Although pesticides are highly effective on pests but they can reside in an environment. Among the class of organophosphate pesticides, chlorpyrifos is widely used in vegetables. Chlorpyrifos has toxic effects on the human body particularly on brain and nervous system.

In another embodiment, enzyme sensor for pesticides detection: Modern biosensors can be miniaturized, mass produced and easily transported. Biosensors can also measure analytes in real-time, which is extremely useful for monitoring rapid changes in biological fluids.A biosensor is universally defined as “a self-contained analytical device that combines a biological component with a physicochemical device for the detection of an analyte of biological importance”. It consists of a biological recognition element which is able to specifically interact with a target molecule and a transducer able to convert this interaction into a measurable signal.Chemical biosensors are based on the presence of a biological element, which is specific for the analyte, and stable under normal conditions of use and storage . Numerous recognition elements have been used in biosensors, such as receptors, nucleic acids, whole cells, antibodies and different class of enzymes.Biosensors are normally classified according to the transduction method they use. In biosensors, the transducer converts a wide array of chemical, physical or biological reactions into an electrical signal . On this basis, optical, calorimetric or acoustic biosensors have been built and characterized, but the most widely used biosensors rely on the electrochemical proprieties of transducers and analytes. Electrochemical biosensors have been studied since the early 1960s when the first glucose oxidase biosensor was developed . Electrochemical biosensors can be impedimetric, potentiometric or amperometric biosensors, where the biochemical signal is transduced into a quantifiable amperometric signal . Enzyme-based amperometric biosensors, in which the production of a current is monitored when a fixed potential is applied between two electrodes, have been widely studied over the last few decades as they are easy to miniaturize, robust and can operate with small sample volumes of rather complex matrices .Designing biosensors requires consideration of both the target analyte and the complexity of the matrix in which the analyte
