Abstract

This cross-sectional study aimed to investigate organophosphate and carbamate pesticide residues in hydroponic vegetables distributed in hydroponic vegetables retailed in Mueang District, Phitsanulok Province using the GT- Pesticide Residual Test Kit of the Department of Medical Sciences, Ministry of Public Health. A total of 48 study samples were composed of 4 types of hydroponic vegetable sampling; red oak lettuce, green oak lettuce, green cos lettuce, and red coral lettuce, sold in 3 retail stores and 1 hydroponic vegetable farm. The samples were collected from June to September 2021.


The results showed that pesticide residues were not detected in 62.5% of all study samples, and 37.5% were found in the range of safe levels. Moreover, red oak lettuce samples were found at the highest levels of acetylcholinesterase inhibition which accounted for 50.0% of all red oak lettuce samples, an average level of acetylcholinesterase inhibition was 7.61 ± 1.39, followed by green oak lettuce, green cos lettuce, and red coral lettuce samples. green oak lettuce samples were in the range of safe levels at 50.0% of all green oak lettuce samples, with a level of acetylcholinesterase inhibition was 5.79 ± 0.47. green cos lettuce and red coral lettuce samples were found in the range of safe levels at 25.0%, with the levels of acetylcholinesterase inhibition being 1.30 ± 0.14 and 1.31 ± 0.12, respectively. However, the detection of pesticide residues in vegetables may affect human health. Therefore, there should be monitoring and surveillance of pesticide residue to decrease the potential impact on health and consumers.
