Description |
The study entitled “Pesticide Residues and Nutritional Quality of Selected Fruits in Central Telangana Zone of Andhra Pradesh” was conducted to estimate the pesticide residues in mango, sapota, guava, banana and papaya in fresh form and after washing and the nutrient composition in fresh fruits. The other objective was to determine whether the pesticide residue levels, if any, of the selected fruits before and after washing were within the Maximum Residue Levels (MRLs). Comparison was made between recommended package of practices versus farmers’ practices in the usage of pesticides and nutrient composition against reference values. Ten farmers each of mango, sapota, and guava while seven banana and five papaya farmers were selected using purposive random sampling. The total forty two farmers were interviewed using the structured questionnaire that was prepared for the purpose. The questionnaire included information on the package of practices in relation to pesticide usage for different fruit crops, dosage/hectare, mode of application, sources for the procurement of seeds and pesticides, processing techniques which includes washing fruits before consumption and affect of pesticides on health. The pesticide dosage values hence found were compared against the recommendations specified by the Package of Practices of the Important Horticultural Crops of Andhra Pradesh (2010) recommended by Andhra Pradesh Horticultural University, in order to check whether the interviewed farmers adhered to the recommendations or if any deviations existed.Burning eyes, nausea and headache were the most common immediate symptoms experienced and most of them used masks, or gloves, very few used both. Nearly twenty four percent did not use any precautionary measure while pesticide application. The reasons for application of pesticides were quoted as higher yield, better quality produce and prevention of pests. The farmers were aware of the use of natural pesticides like neem oil and crude garlic oil instead of chemicals but are not practicing. Most of them did not feel the need for washing the fruits before consumption as they were unaware of the serious health effects of pesticides. The nutrient compositions of selected fresh fruits were comparable with the reference compositions with slight variations in moisture, reducing and total sugars. Whereas, β-carotene levels of mango and papaya samples were almost 26% and 90% less than the reference composition, while vitamin C content of guava sample was 52% less than the reference composition. Such variations could be attributed to varietal differences, soil conditions, seasonal variations, time of maturity and degree of ripeness. Pesticide residue levels in all the selected fruits before and after washing were below detectable limits (BDL). Pesticide residues in fruits were influenced by the time lag between pesticide spray and fruit harvesting, storage, transport, handling and processing techniques like washing and peeling before consumption of fruit. The lower dosages of pesticides applied by the farmers than recommended could have also contributed to the non-detectable levels of pesticide residues in the fruits samples. Thus, the results of the present study indicate that the pesticide residue levels in the selected fruits mango, sapota, guava, banana and papaya of Central Telangana Zone are within the MRL levels and are therefore safe for human consumption. Preprocessing techniques like washing with water or 3% salt water and peeling for obtaining edible portion further reduced the residual burden as the residues fell below detectable levels. |
