Abstracts

This study was conducted to investigate the residual of Chlorpyrifos (CPF) in coffee growing soil at Lam Ha district, Lam Dong province. Fifteen soil samples were collected from coffee intensive gardens in the Phi To, Nam Ha, Me Linh and Dong Thanh communes of Lam Ha district during the February 2023. The physico-chemical properties of the samples were analyzed such as pH, organic carbon, moisture content and mechanical composition of the soil while CPF was analyzed by gas chromatography-mass spectrometry. Soil samples with pH ranged from 3.48-4.45, moisture content 28.2-33.8% and OC 2.3-3.4%. Chlorpyrifos concentration of soil samples ranged from not detected to 954 µg/kg. The ecological risk of chlorpyrifos residual in soil was evaluated by using the risk quotient (RQ). The results of this study will be used to propose solutions to reduce pollution.

Keywords
