Abstracts

Thirty soil samples from 4 communes of Lam Ha district were collected in May and November 2023. The pH, moisture content, organic carbon and mechanical composition were investigated. Two group of pesticides were analyzed including Organophosphorus (Diazinon, Chlorpyrifos, Profenofos, Fenitrothion, Ethoprophos, Glyphosate) and Carbamate (Carbaryl, Mancozeb, Carbosulfan). Maximum concentration of Chlorpyrifos, Profenofos and Carbosulfan founded in soil samples were 391, 63 and 41 µg/kg, respectively. The risk quotient (RQ) of pesticides in coffee growing soils were evaluated for ecological risk assessment. In this study the order from very low to high risk in ascending order from Phi To, Nam Ha, Dong Thanh and Me Linh, respectively.

Keywords
