For decades, pesticides have been a fundamental tool in agriculture, used to control pests and safeguard crops from various harmful agents. Although this practice plays a crucial role in preserving large quantities of produce, it also has significant downsides. One of it huge impact on human should be mentioned is food poisoning. When food poisoning occurs, the contaminated samples are usually sent to specialized agencies for testing and analysis. Identifying the exact substance responsible for the poisoning can be a lengthy process, often taking several days or even weeks. Contributing to the matter, this study investigate the possibility of utilizing spectrometer on the fast detection of pesticide residue in tea sample. Initial results indicates that the absorbance value of samples can be used to detect the existence of and distinguished two different kind of pesticide with concentration as low as 100 ppm in tea sample at 430 nm (p = 0.014, p < 0.05).

摘要

For decades, pesticides have been a fundamental tool in agriculture, used to control pests and safeguard crops from various harmful agents. Although this practice plays a crucial role in preserving large quantities of produce, it also has significant downsides. One of it huge impact on human should be mentioned is food poisoning. When food poisoning occurs, the contaminated samples are usually sent to specialized agencies for testing and analysis. Identifying the exact substance responsible for the poisoning can be a lengthy process, often taking several days or even weeks. Contributing to the matter, this study investigate the possibility of utilizing spectrometer on the fast detection of pesticide residue in tea sample. Initial results indicates that the absorbance value of samples can be used to detect the existence of and distinguished two different kind of pesticide with concentration as low as 100 ppm in tea sample at 430 nm (p = 0.014, p < 0.05).
