The abstract provided by the Pentagon follows: The U.S. Environmental Protection Agency is developing Ecological Soil Screening Level (Eco-SSL) benchmarks for ecological risk assessment of contaminants at Superfund sites. Benchmarks for invertebrates were developed from existing literature. Insufficient information for barium (Ba), beryllium (Be), manganese (Mn), and antimony (Sb) to generate Eco-SSLs necessitated standardized toxicity testing to fill the data gaps. We used the Folsomia Folsomia candida (F. candida) Reproduction Test in this study. This test was selected on the basis of its ability to measure chemical toxicity to ecologically relevant test species during chronic assay, and its inclusion of at least one reproductive component among the measurement endpoints. Tests were conducted in Sassafras sandy loam soil, which supports relatively high bioavailability of metals. Weathering/aging procedures for spiked treatment soil were incorporated into the study to better reflect the "real world" exposure conditions.« less
