“…The coking plant soil had been shown not to affect the survival of adult earthworms at concentrations below 60%, although reproduction was affected [Eom et al, 2007]. Figure 2 established from the results of the former study represents the percentage of decrease in cocoon and juvenile production after 28 and 56 days of exposure of earthworms.…”

“…Percentage of decrease of reproduction endpoints expressed by cocoon production after 28 days, and juvenile production after 56 days in earthworms exposed to different concentrations (10, 20, 40% d.w.) of the coking plant soil in the test medium. Results are expressed as the percentage of response in comparison to ISO controls (percentages are established from data of Eom et al [2007]). An asterisk denotes a significant difference compared with controls with P < 0.05 (data from the study of Eom et al, 2007).…”

“…The soil sample tested was toxic to earthworm reproduction, which was more severely affected than survival [Eom et al, 2007]. Although no effect on survival was recorded in earthworms exposed to concentrations of 20 and 40% of the contaminated soil in the test medium, a significant decrease of cocoon production after 28 days and of juvenile production after 56 days had previously been registered [Eom et al, 2007]. In this study, genotoxicity was investigated within the same concentration range, as that which impaired reproduction.…”

Polluted soil sampled from a former coking plant in Lorraine (France) was studied for its genotoxicity and reproductive effects on the Eisenia fetida earthworm. Genotoxicity was investigated by means of the single-cell gel electrophoresis (comet) assay on the coelomocytes of earthworms after 4 and 10 days of exposure to the soil. DNA damage and a decline in the number of coelomocytes extruded from earthworms were observed at coking plant soil concentrations of 20 and 40% (w/w) in ISO soil. These soil concentrations had previously been shown to significantly reduce cocoon and juvenile productions after 28 and 56 days of earthworm exposure, respectively. The results showed that genotoxic pollutants in the tested soil were still bioavailable despite the age of the contaminated soil. Similar values of the no-observedeffect concentration (NOEC) corresponding to 10% of the contaminated soil and of the lowest soil concentration tested inducing effects (LOEC) corresponding to 20% of the contaminated soil were obtained from reproductive and genotoxicity endpoints. Among the soil pollutants measured, polycyclic aromatic hydrocarbons (PAHs) appeared to be the most likely source of the genotoxicity recorded, although effects of metals could not be excluded. Measurement of genotoxicity in earthworms could complement the existing standardized tests used in the ecotoxicological assessment of the risk associated with contaminated soils. Environ. Mol. Mutagen. 50:60-67, 2009.

“…However, this method failed to obtain accurate results, due to the difference in sensitivity between various instruments and as the analysis included those chemical compounds that are not available to the biological system. Therefore, a biological approach is useful to integrate the effects of all the bioavailable contaminants and their interaction (Eom et al 2007;Ansari and Mali 2009), and the necessity of using biological monitors has arisen (Simkiss et al1982;Fernandez et al 2005). With increasing concerns as to the genotoxicity of hazardous chemicals and pollutants in water, air and soil, several plant system bioassays have been developed for detecting the genotoxicity of environmental pollutants.…”

The article presents the geochemical and biogeochemical characteristics of heavy metal elements within the soil-plant system in the Hetai mine-abandoned areas and wasteland, China. The cytogenetic toxic effects of gold mine wastelands environment on the chromosome and micronucleus were analyzed by genetic methods. The results showed that abundances of Au and Au-associated heavy metal elements such as Cu, As, Cd, Pb and Hg in soils, plants and the pigments in those abandoned mine areas were much higher than those in the background region. The cell structures of the plants in the abandoned mine areas were anomalous and aberrant, and there were many nano-metal particles diffused in the cells. Moreover, the heavy metal elements in those abandoned mine areas had entered the ultrastructure and caused toxicities to the organism.
