In the present work, a chemometric-assisted spectrofluorimetric method has been developed for the simultaneous determination of natural fluorescent pesticides, carbaryl, carbendazim, and thiabendazole, in orange and banana. Only a simple extraction with methanol was required as sample pretreatment.

Bioactive Molecules in Food pp Cite as. Fruits and vegetables play an important role in human nutrition and health; they constitute an important part of our daily diet. They are important sources of carbohydrates, vitamins, trace minerals, and antioxidants. Therefore, they can be contaminated by pesticides used for the protection of their culture. The use of pesticides to control pests in fruits and vegetables can lead to the presence of pesticide residues.

This project is a bonafide piece of work carried out with the consultation of supervisor. Pal and Mrs. Bala for their guidance and advices to complete my work successfully. I also thank our principal for providing me all the facilities to finish the project on time. I also take this opportunity to thank my Parents for the countless blessings showered on me while doing the work and for encouragement and support in my humble venture. In the past decade there has been a tremendous increase in the yields of various crops to meet the demand of overgrowing population, achieved by using pesticides and insecticides.
To the filtrate add 1ml freshly prepared ferrous sulphate solution and warm the contents. Then, add drops of ferric chloride solution and acidity with the dil. Hydrochloric acid if a blue or green precipitate or colouration is obtained, it indicated the presence of nitrogen containing insecticide.
Pesticides are substances that are meant to control pests. As an example - The fungus Alternaria is used to combat the Aquatic weed, Salvinia. In general, a pesticide is a chemical such as carbamate or biological agent such as a virus , bacterium , or fungus that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens , weeds, molluscs , birds , mammals , fish , nematodes roundworms , and microbes that destroy property, cause nuisance, or spread disease, or are disease vectors. Along with these benefits, pesticides also have drawbacks, such as potential toxicity to humans and other species.
To Study the presence of insecticides or pesticides Nitrogen Containing in various fruits and vegetables. In the decade, there has been a tremendous increase in the guilds of various crops to meet the demand of our growing wrold population. This great feat has been achieved by adopting new methods of forming and by expensive use of fertilizers and insecticides. A pesticide is any substance is mixture of substance intended for preventing, destroying repelling or mitigating any pest. A pesticide may be a chemical substance, biological agent antimiolbal disinfectant or device used against any pest.
A basic aim of using chemical products for plant protection pesticides in farming is the quantity increase and quality improvement of agricultural crops. Pesticides are destined, inter alia, to control any kinds of pests, weeds, pathogenic organisms and other factors which cause plant damage. Therefore, the use of these substances, which have biocidal effects, is deliberately introduced on crops and get through them to people.
