Fluoride is widely found in industrial wastewater,pesticides,and fertilizers,posing significant threats to soil environments.The accuracy of soil fluoride measurement is affected by various factors,with blank value processing being a key one.This study examines the impact of blank value processing on environmental monitoring results in soil fluoride measurement.The results show that when using the ion-selective electrode method,subtracting 40.25 μg from the blank value causes measurements to fall below the true value range of 524±30 mg/kg or 610±6 mg/kg,while not subtracting it results in 509.5-529.5 μg and 605.5-609.5 μg,closer to the true values.These findings provide a reference for improving the accuracy of environmental monitoring data and emphasize the need for caution in blank value processing during fluoride measurement.
