“…Similar observation was made by Liesch et al (2010) on the use of biochar containing potentially toxic micronutrients, including As, Zn, Cu, Fe, and on Eisenia fetida applied to an artificial soil, which caused loss of weight reaching 100% and the growth rate of earthworm loss reaching 100%. Other results confirmed, the results of Belmeskine et al (2012) study, which used the Eisenia andrei earthworm in their research. They found toxicity of PCDD/Fs mixtures to earthworms during 28-day exposure, there was less effect when earthworms were exposed to C1 (0.1 ng 2, 3, 7, 8-TCDD/g soil), while the worms exposed to C2 (1 ng 2, 3, 7, 8-TCDD/g soil) presented pronounced effects and were significantly different from the control.…”

Earthworms are key to the earth's ecosystem, which helps the soil increase its fertility and repair its existing elements, as well as remove contaminants. This study investigated the accumulation of Zn in the earthworm Aporrectodea caliginosa after 15 days of exposure. The worms were grown in media with different concentrations of Zn between 750 and 1500 ppm. Each treatment consisted of three replicates, containing 30 worms. A control group without Zn was also used. Data were analyzed by using Duncan Multi–Range. The results revealed that A. caliginosa had a strong ability to accumulate Zn in its tissue compared to the control group. It was noticed that the increase of the heavy metal in the worm´s tissue is associated with the elevation of the metal in its media. The results show a significant loss of weight in the worm´s body and loss in the growth rate; they also shown a decrease in specific growth rate. Moreover, there was a significant decrease in the worm length, showing a high effect, especially after 15 days of breeding with all concentrations used in this study. The researchers recommend using earthworms to purify the soil from contaminants because earthworm has a great ability to get rid of all pollutants, whether metals or pesticides or parasites, especially in industrialized countries and agricultural lands.

The importance and beneficial effects of earthworms on soil structure and quality is well-established. In addition, earthworms have proved to be important model organisms for investigation of pollutant effects on soil ecosystems. In ecotoxicological investigations effects of various pollutants on earthworms were assessed. But some important issues regarding the effects of pollutants on earthworms still need to be comprehensively addressed. In this review several issues relevant to soil ecotoxicological investigations using earthworms are emphasized and guidelines that should be adopted in ecotoxicological investigations using earthworms are given. The inclusion of these guidelines in ecotoxicological studies will contribute to the better quantification of impacts of pollutants and will allow more accurate prediction of the real field effects of pollutants to earthworms.

“…Polychlorinated dibenzo-p-dioxins (PCDDs) are known to be a series of highly toxic and persistent environmental contaminants that tend to accumulate in bio-tissues and induce numerous adverse effects, including immunotoxicity, neurotoxicity, hepatotoxicity, terotogenesis, and carcinogenesis (Alaluusua et al, 2004;Belmeskine et al, 2012;Chen et al, 2012). These hazardous compounds are widely dispersed in soils and sediments, water, organisms, and even in the human body (Chan and Wong, 2013).…”
