BookPublisher: 2013Subject(s): Institute of Biochemistry & BiotechnologyDDC classification: 1510,T Dissertation note: Pesticides are the chemicals which are used to kill or repel the unwanted objects such as pests. Different types of pesticides are present which undergo a different mechanism and kill the pests. Four different types are being used in Pakistan such as organophosphate, organochlorine, pyrehtroid and carbamates. Use of organophosphate and organochlorine become less due the presence of residues. Use of pesticides is increased for a number of purposes such as to increase the rate of production, to decrease the damage of crops and to increase the saving time of different vegetables.
Vegetables are the main source of income of Pakistan, and vegetables are common in our use. Vegetables contain different nutritional elements of our diets. That's why vegetables play an important role in the nutritious diet of a person. The spray of different chemicals on vegetables not only decreases the nutritional elements but also increase the risk of different diseases.
As pesticides leave their residues in vegetables, different techniques can be used to detect the residues and their maximum residue limit, at which limit these pesticides are harmful for humans. Pesticides can also act on unintended individual such as human beings and cause different acute and chronic diseases.
Different vegetables were selected for analyses that are common in use and available in every season. Pesticides which were selected are that which are common in Pakistan and from different pesticide classes.
In present study vegetables of different areas of Lahore were collected and analyzed through HPTLC and GC/MS. HPTLC was used to analyze and calculate the concentration and GC/MS was used for the confirmation of results, and it was concluded that which vegetable contain the high concentration of pesticides. It was studied that which vegetable absorb large amount of pesticides. Potato, tomato, egg plant, okra and cucumber of different markets of Lahore contain high concentration of pesticides as compared to the other vegetables.
