Assessment of Soil Fluorine Spatial Distribution around Brick Kilns Using GIS Application

摘要

Soil fluorine is naturally occurring micronutrient and also considered as essential element for health of humans and animals. But higher concentration of soil fluorine leads to water pollution and cause damages to plants. Brick kilns are one of main source of Fluorine emission in form of Hydrogen Fluoride which accumulate in the surrounding soil. So it is need to identify soil fluorine pollution hotspots necessary for improved and better management. ArcGIS is very useful application for analyzing spatial variation and mapping of pollution. In present study cluster and outlier analysis based on Local Moran Index was used to know the geo-statistically significant hotspots area. For interpolation and prediction, Inverse Distance Weighting method was used to analyze the spatial distribution patter of fluorine in soil around brick kilns.
