AbstractSoil contamination by metals is a common problem encountered in many industrialized countries. In this work we present a new approach for heavy metals detection by using surface-enhanced Raman scattering (SERS) spectroscopy. Zn(II) can be clearly determined by SERS in contaminated soil by using 4-(2-pyridylazo) resorcinol (PAR) as chelating molecule for the metal ion. The SERS spectra of PAR, of its metal chelates and of the soil extract-PAR mixture were recorded using a hydroxylamine reduced silver colloid. An excellent match of the PAR-contaminated soil extracts SERS spectrum to the Zn(PAR)2 SERS spectrum can be observed, demonstrating the presence of Zn(II) in the soil probes. Density functional theory (DFT) based calculations were also performed for a reliable assignment of SERS spectra.

ABSTRACT The ability of some halophytes to accumulate salts may make them helpful in remediating soil contaminated with produced water and drilling mud from oil and gas exploration and production. Three inland halophytes, Atriplex acanthocarpa (two accessions) and A. canescens, were grown in pot culture in salt-contaminated soil, soil contaminated with salt and hydrocarbons, and uncontaminated soil collected from a Webb Co., Texas, gas production site. Electrical conductivity and soluble sodium of the soil extract were determined prior to planting and re-analyzed following harvest. Total sodium content in mature leaves was determined following harvest. Mature plant survival for all species in all soils ranged from 90–100%. In the salt-contaminated soil, post-harvest electrical conductivity and soluble sodium were significantly lower in the planted soils than in the unplanted soil. For each accession, biomass and plant mortality were greatest in the salt-contaminated soil. In both contaminated soils, the local ecotype of A. acanthocarpa had the highest concentration of tissue sodium and produced the greatest decrease in both electrical conductivity and soluble sodium. Field studies are necessary to determine the effectiveness of in situ application.
