Determination of Pre-Harvest Interval, Pesticide Contamination and Consumer Awareness to Reduce Pesticide Residues in Vegetables: A Case Study in Local Market of Vavuniya, Sri Lanka | Chapter 1 | Challenging Issues on Environment and Earth Science Vol. 9

Pesticides are used to kill pests, but they are also dangerous to humans. Pesticide contamination is detected using a variety of methods, and the pesticide’s residual effect is reduced as a result of customer knowledge. The goal of this study was to identify pesticide residues in various vegetables based on their scent and appearance. In

Analytical Techniques for Determining Chloropyrifos in Fruits and Vegetables | Chapter 7 | Recent Trends in Chemical and Material Sciences Vol. 1

For the detection of chloropyrifos, highly sensitive spectrophotometric and gas chromatographic methods were established. The base was chloropyrifos alkaline hydrolysis to 1,2,4-trichloropyridine, followed by coupling with congored in the presence of nitric acid. At 605nm, the absorption maxima of blue colour formed at 800-900C. In the range of 0.5-5.7 ppm, Beer’s law was followed. 0.005
