    Soil from a site heavily contaminated with polychlorinated biphenyls (PCBs) was treated with a pilot-scale, solvent extraction technology. Bioassays in earthworms and plants were used to examine the efficacy of the remediation process for reducing the toxicity of the soil.

Earthworm bioassays are a widely recognized tool for evaluating the toxicity of contaminated soils. The earthworm bioassay described in this document is intended to be used in screening level assessments of soil toxicity at hazardous waste sites being investigated under the Washington Model Toxics Control Act Cleanup Regulation.

Earthworm Bioassay. Earthworm Bioassay. Contaminant bioaccumulation and toxicity are often poorly related to total soil contaminant content.

Contaminant bioavailability may be a better predictor. Soil properties and site remediation may affect metal bioavailability to ecological receptors. Earthworms have been used as a model organism for soil toxicity studies due to their high rates of consumption of organic matter in soil and direct contact with soil constituents, and have been useful in correlating laboratory with field study findings (Environment Canada, ).Cited by: This Test Guideline includes two methods: a paper contact toxicity test and an artificial soil test.

The recommended specie is Eisenia foetida (Michaelsen). The initial screening test (filter paper contact test) involves exposing earthworms to test substances on moist filter paper in order to identify potentially toxic chemicals to earthworms in soil.

Summary. Three different laboratory earthworm protocols for assessing the potential toxicity of environmental samples were evaluated using Eisenia h Contact Test (CT) is a short test and may indicate the presence of water-soluble by: Bioassays in earthworms and plants were used to examine the efficacy of the remediation process for reducing the toxicity of the soil.

Domínguez-Rodríguez, Randy H. Adams, Fabián Sánchez-Madrigal, José de los S. Pascual-Cha. We describe a novel bioassay, the “dispersal assay,” that is a simple and rapid technique for field‐based soil quality evaluations. It is based on the premise that earthworms prefer optimal soils if given the choice.

Thus, assay tubes containing a reference soil were inserted in target sites, and earthworms were placed into these : Shin Woong Kim, Dokyung Kim, Jongmin Moon, Yooeun Chae, Jin Il Kwak, Younsu Park, Seung-Woo Jeong, Y.

Earthworm acute toxicity, plant seed germination/root elongation (SG/RE) and plant genotoxicity bioassays were employed to evaluate the remediation of a lead-contaminated soil. The remediation involved removal of heavy metals by a soil washing/soil leaching treatment process. A portion of the soil after remediation was rinsed with water in order to simulate exposure to rainfall.

The toxicity tests on earthworms () were conducted in natural soil gathered from the top 15 cm of a seldom disturbed mountain area (°57'"E, 32°8'"N) at Qixia District, in Nanjing, Jiangsu province, east is a typical yellow brown soil classified as Alfisols according to the USDA soil classification with a pH (in water) ofa clay content Cited by: Unfortunately, many property owners in southeastern Mexico do not trust environmental authorities, and the de facto method they use to evaluate the progress in environmental remediation projects is soil smell.
