“…A preset microwave program of 15 minutes was adjusted in three steps, as follows: 5 minutes at 500 W, followed by 7 minutes at 400 W, followed by 3 minutes at 250 W. The samples were filtered and analyzed for heavy metals. Estimation of heavy metals was carried out as described by Marinussen et al (1997) . Extraction of organically bound and exchangeable forms of heavy metals in substrates was carried out as per the method described by Emmerich et al (1982) .…”

The effect of heavy metals on the activities of earthworm species Eudrillus eugineae was studied during vermicomposting of municipal solid waste (MSW) spiked with heavy metals. The activities of earthworms, in terms of growth and biomass production and number of cocoons produced, were monitored periodically, and the concentration of heavy metals in earthworms and substrates was determined at definite intervals. Laboratory-scale experiments were performed by mixing individual heavy metals in MSW. Copper, cadmium, chromium, lead, and zinc were selected for the study. The study concludes that heavy metals tend to accumulate in the body of earthworms; hence, the inherent concentration of heavy metals in the substrate before vermicomposting must be considered in view of composting of MSW and its application to soil. It was observed that copper and cadmium were toxic for the worms at 1.5 and 0.1 g/kg of the waste, respectively. The studies also suggest that earthworms are susceptible to the free form of heavy metals. Cadmium is the most toxic metal, followed by copper. Based on the investigation and observation, it was also found that earthworms should be separated from castings before the use of castings in soil amendments. Water Environ. Res., 80, 154 (2008).

“…However, level of these metals in the environment has increased tremendously in the past decades as a result of human inputs and activities. Motor vehicles introduce quite a number of toxic chemicals into the environment among which are Cd, Pb, Zn and Cu that are increasingly detected in vegetation and soil (Fatoki and Hill, 1994;Dudka et al, 1996) and in lower animals along major roads since organisms inhabiting contaminated soils are known to take up heavy metals (Marinussen et al, 1997;Nuorteva and Elberg, 1999).…”

The concentration of trace metals (Cd, Cu, Pb and Zn) in a total of 144 samples of grass, soil and lower animal (earthworm, Lybrodrilus violaceous) were collected and analysed for their metallic content. Levels of cadmium ranged from 0.01-0.07 microg g(-1); 0.01-0.12 microg g(-1) and from trace-0.05 microg g(-1) dry weight for plant, soil and animal samples respectively. Mean concentration of copper ranged 0.10-1.48 microg g(-1); 0.10-2.90 microg g(-1) and 0.01-0.08 microg g(-1) for samples in similar order as above. The levels of Pb varied from 0.01-0.14 microg g(-1); 0.02-0.23 microg g(-1) and from trace-0.07 microg (g-1) while that of Zn ranged from 0.19-1.80 microg g(-1); 0.51-3.35 microg g(-1) and 0.01-0.08 microg g(-1) also in the same order of samples as mentioned above. Levels of metals in soil samples were higher than the background levels with the exception of Zn but lower than European Union (EU) limits. The results generally revealed the presence of metals in plant and animal samples and metal dynamics up the food chain is highly possible. Acceptable recoveries of the spiking experiment validate the experimental protocol.

“…However, only a few studies describing the toxicity impact of chemical mixtures on earthworms have been published thus far, all of which focus on metals (Condor and Lanno 2000;Khalil et al 1996a, b;Marinussen et al 1997;Weltje 1998). In contrast, our study investigated the effect of a fungicide (carbendazim), an insecticide (dimethoate), and a herbicide (glyphosate) on the fecundity of earthworm species E. fetida.…”

We investigated the effects of three different pesticides (carbendazim, dimethoate, and glyphosate) and their mixture on the growth and reproduction of the earthworm species, Eisenia fetida. The study was conducted following the suggestion of the International Workshop on Earthworm Ecotoxicology. The results showed that the pesticide treatment had a marked negative impact on the growth and reproduction of earthworms. Carbendazim and dimethoate were found to cause greater harm to the selected earthworm species than glyphosate.
