The Effect of Arsenic on the Free Amino Acid Composition in Soil
Laboratory experiments were performed to evaluate the effect of arsenic on the free amino acid composition in soil. The samples were contaminated with arsenic in the form of sodium arsenate(V) at different concentrations (0, 0.1, 1, 5, 50, 200, 1200, 4000 mg/kg As). There were no changes in the amin...

| Summary: | Laboratory experiments were performed to evaluate the effect of arsenic on the free amino acid composition in soil. The samples were contaminated with arsenic in the form of sodium arsenate(V) at different concentrations (0, 0.1, 1, 5, 50, 200, 1200, 4000 mg/kg As). There were no changes in the amino acid composition for the concentrations of 0.1–0.5 mg/kg As(V). The amino acids content in-creased at the concentrations of 50 and 200 mg/kg As(V). After the addition of 1200 mg/kg arsenic, the content of polar uncharged amino acids decreased as compared to the control sample. |
