Studies were carried out on the speciation of heavy metals (Zn, Cu, Mn, Fe, Ni, Pb, Cd, and Cr) during rotary drum composting of water hyacinth (Eichhornia crassipes) for a period of 20 days. Five different proportions of cattle manure, water hyacinth and sawdust were prepared for composting. This study concluded that, rotary drum was very efficient for the degradation of organic matter as well as for the reduction of mobility and bioavailability of heavy metals during water hyacinth composting. The results from the sequential extraction procedure of heavy metals shows that rotary drum composting changed the distribution of five fractions of Zn, Cu, Mn, Fe, Ni, Pb, Cd, and Cr. The highest reduction in the bioavailability factors of Pb and Cd was observed during the process. The total concentration of Cu, Cr, and Cd was very low compared to the other metals (Zn, Mn, Fe, Ni, and Pb); however, the percentage of exchangeable and carbonate fractions of these metals was similar to other metals. These results confirmed that the bioavailability of metals does not depend on the total concentration of metals. From this study, it can be concluded that the addition of an appropriate proportion of cattle manure significantly reduced the mobile and easily available fractions (exchangeable and carbonate fractions) during water hyacinth composting in rotary drum.

“…Singh and Kalamdhad (2013) found similar concentrations of Zn, Mn, Cu and Fe after 45 days of vermicomposting. Nevertheless, a high pH reduce bioavalibility of these metals (Ingelmo et al 2012). The concentrations of Co and Cu in the three treatments were below the upper limits reported by the European Comission (2014) and WRAP (2014).…”

Aquatic weeds, such as Eichhornia crassipes (Mart.) Solms (water hyacinth) can be used as raw material for vermicompost. Vermicompost is the product of microbial decomposition of organic waste through the digestive tracts of earthworms. The aim of this work was to use water hyacinth to obtain stable and mature vermicompost. Three treatments were performed for vermicomposting, treatment one with 100 % of water hyacinth, treatment two with 100 % of cow manure and treatment three with 50 % of water hyacinth and 50 % of cow manure. The earthworm used was Eisenia fetida Savigny. Vermicompost was characterized physically, chemically and microbiologically, and measured by indexes of stability and maturity, as well, metal concentrations were detemined. Germination index was obtained with four different seeds: radish (Raphanus sativus L.), lettuce (Lactuca sativa L.), cucumber (Cucumis spp.) and zucchini (Cucurbita pepo L.). The three different treatments for vermicompost were stable and mature after 110 days with 90 % of E. fetida survival in each treatment. The vermicompost with water hyacinth and water hyacinth plus cow manure had a high pH and electrical conductivity. Radish had the best performance in germination index and the three vermicompost were rich in metals. We conclude that vermicomposting is suitable for managing water hyacinth because it can produce a stable, mature, and rich in nutrients vermicompost, which is useful as organic fertilizer or soil improver. 426descomposición de desechos orgánicos por medio de los microorganismos del tracto digestivo de las lombrices. El objetivo de este trabajo fue utilizar el lirio acuático para obtener un vermicompost estable y maduro. Se realizaron tres tratamientos: uno con el 100 % de lirio acuático, el dos con 100 % de estiércol y el tres con 50 % lirio acuático y 50 % de estiércol, la lombriz utilizada fue Eisenia fetida Savigny. Los vermicompost se caracterizaron física, química y microbiológicamente, además se midieron índices de madurez y estabilidad, así como la concentración de metales. El índice de germinación se realizó con cuatro semillas diferentes: rábano (Raphanus sativus L.), lechuga (Lactuca sativa L.), pepino (Cucumis spp.) y calabacita (Cucurbita pepo L.). Los tres tratamientos resultaron ser estables y maduros después de 110 días de vermicompostaje con un índice de supervivencia de E. Fetida de 90 %, los vermicompost con lirio acuático y lirio acuático más estiércol tuvieron un pH y una conductividad eléctrica altos. El rábano mostró un buen desempeño en el índice de germinación, los tres vermicompost resultaron ricos en metales. Se concluye que el vermicompostaje es adecuado para el manejo del lirio acuático, debido a que se obtiene un vermicompost estable, maduro y rico en nutrientes, que puede utilizarse como fertilizante orgánico o mejorador de suelos.

“…The heavy metal composition of composts varies widely depending on the geographical location, sources and composting process (Faridullah et al, 2014). Ingelmo et al (2012) reported on digested sewage sludge (collected from Spanish farms), during the compost process. They found that the heavy metal content varies and total Zn, Pb, Cu and Ni content increased during the composting process.…”

The aim of this review is to focus the attention on the nutrition ecology of the heavy metals and on the major criticisms related to the heavy metals content in animal feeds, manure, soil and animal-origin products. Heavy metals are metallic elements that have a high density that have progressively accumulated in the food chain with negative effects for human health. Some metals are essential (Fe, I, Co, Zn, Cu, Mn, Mo, Se) to maintain various physiological functions and are usually added as nutritional additives in animal feed. Other metals (As, Cd, F, Pb, Hg) have no established biological functions and are considered as contaminants/ undesirable substances. The European Union adopted several measures in order to control their presence in the environment, as a result of human activities such as: farming, industry or food processing and storage contamination. The control of the animal input could be an effective strategy to reduce human health risks related to the consumption of animal-origin products and the environmental pollution by manure. Different management of raw materials and feed, animal species as well as different legal limits can influence the spread of heavy metals. To set up effective strategies against heavy metals the complex interrelationships in rural processes, the widely variability of farming practices, the soil and climatic conditions must be considered. Innovative and sustainable approaches have discussed for the heavy metal nutrition ecology to control the environmental pollution from livestockrelated activities.
