Over the past two decades, soil ecotoxicologists have made strides in utilizing the basic concepts
and advancements in soil zoology and ecology. They have applied the existing tools, and
developed new tools to investigate how chemical contamination can affect soil ecosystems,
including the degradation or destruction of soil habitats, diminishment of below-ground biodiversity,
and negative impacts on complex food webs and the associated above-ground biotic
communities. Soil ecotoxicologists at present are applying a suite of standard protocols, originally
developed for laboratory soil toxicity testing, and further enhancing both the approaches and
protocols for the assessment of contaminated lands. The current challenge is how to integrate
species-specific sensitivities, the effects of physical and chemical soil properties, contaminant
bioavailability and toxicity, uptake and bioconcentration, and spatial and temporal variations in
abundance and diversity of soil organisms, into coherent toxicological assessments of soil
ecosystems amid contaminated lands. This overview will attempt to address the question that
usually confronts an ecotoxicologist in any assessment of a soil ecosystem: ?Which terrestrial
toxicity tests constitute an appropriate test battery?? There is a plethora of methods that focus
on the assessment of soils via spiking, or amendment, with chemicals or other test substances.
However, only those methods that contain procedures for assessing contaminated site-specific
soils (or those methods that can easily be adapted for that purpose) are recommended for such
a test battery, and those will be discussed in this overview. Important considerations that will be
addressed include: 1) a need for a greatly improved understanding of the potential effects of
chemical contaminants on the structure and function of soil ecosystems; and 2) ready availability
of reliable appropriate soil toxicity test methods that have been developed explicitly to assess
the toxicity of contaminated site soils. International soil toxicity test methods that have been
standardized, or those that are in the process of being standardized, will also be reviewed. MenosOver the past two decades, soil ecotoxicologists have made strides in utilizing the basic concepts
