Description
Diego Alejandro Riaño-Herrera and colleagues validate in 2026 a method for measuring 48 different pesticides at trace levels in tropical farm soils. Soil is a messy matrix, so the team adapted the QuEChERS approach, a quick extraction scheme, and paired it with tandem mass spectrometry. The method stayed linear across a wide range, from 5 to 600 micrograms per kilogram, and recoveries met the accepted 70 to 120 percent band in 91 percent of cases.
Precision also passed standard guideline checks, with nearly all repeat measurements within 20 percent variation. The validated method was then applied to real soils from Puerto Carreño in the Colombian Orinoquia, which proved sandy, slightly acidic, and poor in organic carbon. A dependable multi-pesticide soil test gives tropical agriculture regions numbers they can act on for food safety and environmental monitoring.
