Toxicity of a Hydrogen Peroxide-Based Decontamination Solution (Decon Green) in Water and Soil Extracts
Abstract
The U.S. Army has developed a hydrogen peroxide-based decontaminating solution, Decon Green (DG). The components of the decon solution are less hazardous to the end-user and the environment than standard decon solutions that are in the current inventory. Toxicity studies were conducted as direct amendments of DG into water, and into soil. Aquatic organisms were exposed directly to water amended with DG. Soils amended with DG were subjected to an Adapted Toxicity Characteristic Leaching Procedure (ATCLP) in order to produce exposure solutions. In addition, we performed corresponding toxicity investigations using DG solution tat was allowed to age. Overall, Vibrio fischeri was less sensitive to DG than D. magna and C. dubia by approximately one order of magnitude. Provisional data indicate that 5-min EC50 for Vibrio fischeri was 200 ppm (vol/vol), and the 48-hr EC50 for D. magna and C. dubia were 26 and 25 ppm (vol/vol), respectively; IC50 for C. dubia exposed to DG directly amended into water was 28 ppm (vol/vol), while IC50 for C. dubia exposed to extracts of soils amended with GD was 2400 ppm (mass/mass; in soil). Based on acute aquatic toxicity, DG was substantially less toxic to these organisms than traditional decontamination solutions.
