Abstract

A study of the nanoporosity of soils was conducted to determine the correlation between several soil properties and nanoporosity as measured by mercury-intrusion porosimetry. The volume of pores with diameters 104 nm and the surface area of these nanopores differed greatly among 16 soils. The volume and surface area of nanopores in some soils were mainly in pores of diameters < 100 nm. In others, the volume and surface area were associated chiefly with pores of 103-104 nm diameter. The volume was correlated with organic C content for pores of diameters of 103-104 nm and 102-103 nm (r values of 0.583 and 0.688, respectively) and clay content for pores with diameters < 102 nm (r value of 0.512). The surface area of the soils was correlated with volume of pores < 100 nm (r = 0.956). As a result of the abundance of nanopores and the large surface areas associated with them, we suggest that additional research be conducted to assess their importance in soil toxicology.
