“…This signified that the abattoir soils in this study contained higher levels of heavy metals than the control site soil. This agreed with the work of Gupta, Tewari, Srivastava, Murthy, and Chandra (2005), who reported that earthworm tissue metal level is directly related to their proportion in a given soil. Similar pattern of metal bioaccumulation was observed by Suthar, Singh, and Dhawan (2008).…”

Abstract:The use of direct response of animals to environmental challenges by production of biomarkers is a better tool to assess environmental pollution than the conventional methods. This study aimed to measure Glutathione-S-transferase (GST) in earthworms as tools for assessing heavy metal pollution in abattoir soil. Five (5) replicates each of earthworm species (Libyodrilus violaceous, Eudrilus eugeniae and Alma millsoni), soil and rumen waste samples were collected from three (3) abattoir sites (Lafenwa, Gbonogun and Madojutimi abattoirs), and a control site located within Federal University of Agriculture Abeokuta, beside an undisturbed stream with no rumen waste. Heavy metal (Cu, Zn, Pb, Cd, Co, Cr, Ni and Mn) concentrations in rumen waste, abattoir soils and earthworm tissues were determined using Atomic Absorption Spectrophotometer. The pH and organic matter (OM) concentrations of the rumen waste and abattoir soils were determined by standard methods. GST activities in the earthworm tissues were determined through the conjugation of 1 mM reduced glutathione (GSH) with 1 mM 1-chloro-2,4-dinitrobenzene (CDNB). The rumen waste recorded significantly higher (p ≤ 0.05) % OM, heavy metal concentrations and pH level than in their respective abattoir soils. The mean heavy metal concentrations of Cu, Zn, Pb, Cd and Mn were highest in the tissue of earthworm species obtained from Lafenwa abattoir. A significantly (p ≤ 0.05) higher GST activities were recorded in the tissue of earthworm species obtained from Lafenwa and Gbonogun abattoirs. Libyodrilous violaceus obtained from Lafenwa abattoir recorded the highest GST activity (8.47±1.39) in their tissue followed by the ones from Gbonogun abattoir (8.21±0.85). A significant (p ≤ 0.05) positive correlations was observed between GST activities in earthworm tissues and heavy metal concentrations. GST activities can therefore be used to assess the level of heavy metal pollution in abattoir soils. Rev. Biol. Trop. 64 (2): 779-789. Epub 2016 June 01.

“…Some of the metals accumulated in body tissues and some was likely lost through leaching. Previous studies have revealed that earthworms can accumulate heavy metals in their tissues during the process of vermicomposting (Hartenstein and Hartenstein 1981;Graff 1982;Garg and Kaushik 2005;Gupta et al 2005). Garg and Kaushik (2005) reported a considerable loss in heavy metal contents from solid textile mill sludge mixed with poultry droppings.…”

“…They attributed the heavy metal loss from substrate to accumulation by earthworm body tissues. Gupta et al (2005) studied the vermicomposting of fly ash by mixing it with cow dung in different ratios and reported 30-50% loss in heavy metal content in different combination, at the end. They reported that heavy metals bioaccumulated in earthworm tissues.…”

The potential of the epigeic earthworm Eisenia fetida to stabilize sludge (generated from a distillation unit of the sugar industry) mixed with cow dung, in different proportions i.e. 20% (T 1 ), 40% (T 2 ), 60% (T 3 ) and 80% (T 4 ) has been studied under laboratory conditions for 90 days. The ready vermicompost was evaluated for its' different physico-chemical parameters using standard methods. At the end of experiment, all vermibeds expressed a significant decrease in pH (7.8-19.2%) organic C (8.5-25.8%) content, and an increase in total N (130.4-170.7%), available P (22.2-120.8%), exchangeable K (104.9-159.5%), exchangeable Ca (49.1-118.1%), and exchangeable Mg (13.6-51.2%) content. Overall, earthworms could maximize decomposition and mineralization efficiency in bedding with lower proportions of distillery sludge. DTPA extractable metal reduction in substrate was recorded between the ranges of 12.5-38.8% for Zn, 5.9-30.4% for Fe, 4.7-38.2% for Mn and 4.5-42.1% for Cu. Maximum values for the mean individual live weight (809.69 ± 20.09 mg) and maximum individual growth rate (mg wt. worm )1 day )1 ) (5.81 ± 0.18) of earthworms was noted in T 1 treatment, whereas cocoon numbers (69.0 ± 7.94) and individual reproduction rate (cocoon worm )1 day )1 ) (0.046 ± 0.002) was highest in T 2 treatment. Earthworm mortality tended to increase with increasing proportion of distillery sludge, and maximum mortality in E. fetida was recorded for the T 4 (45.0 ± 5.0) treatment. Results indicate that vermicomposting might be useful for managing the energy and nutrient rich distillery sludge on a low-input basis. Products of this process can be used for sustainable land restoration practices. The feasibility of worms to mitigate the toxicity of metals also reduces the possibility of soil contamination, which has been reported in earlier studies during direct field application of industrial wastes.

Exploring chemical analysis of vermicompost of various oil palm fibre wastes

The aim of this work was to study the physical and chemical properties of different oil palm wastes, viz. empty fruit bunch (EFB), oil palm frond (OPF) and oil palm trunk (OPT). A study (84 days duration) was conducted to evaluate the efficiency of an exotic earthworm species (epigeic-African Nightcrawler (Eudrilus euginae)) for the decomposition of different types of oil palm wastes (EFB, OPT and OPF) into valuable vermicompost. The decrease in earthworm's biomass gain for EFB, OPT and OPF may be due to exhaustion of worm feed in vermicomposters. The percentage of nitrogen, phosphorous and potassium in vermicompost was found to increase while pH and total organic carbon declined as a function of the vermicomposting period. The vermicompost obtained showed an increase in heavy metal content for all the reactors, but levels were still in the range of nutrient in the vermicompost. The data reveal that vermicomposting (using African Nightcrawler) is a suitable technology for the decomposition of oil palm wastes, especially EFB into value-added material.
