Study on the Impact of Soil Fluoride Measurement on Environmental Monitoring Results
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.
