hydrofluoric acid in Korea. Gaseous hydrogen fluoride dispersed was suspected to have
contaminated the surrounding soil environment. Total and water soluble F concentrations in
soil within a 1 km radius of the spillage were determined. Total F concentrations (mean=
222±70.1 mg kg− 1) were lower than the Korean limit value (ie, 400 mg kg− 1) and several
reported measurements of background F concentrations in soils except for a single outlying …
