“…The composting process is affected by the physicochemical properties of raw materials. In this study, the high heavy metal content in original tannery sludges decreased sharply during the composting process, like in studies developed by Gonçalves et al [7]. The presence of heavy metals in the composted residues proved to be much lower than the limits established in national legislation [21], being possible for their application to the soil as organic fertilizers.…”

“…Eco-friendly technologies for managing these solid wastes, such as composting, are being widely promoted as effective and environmentally friendly processes for solid waste management [12,13]. Composting has been used to process sludge of different origins, such as textile sludge [7,14], and is considered an efficient method for tannery sludge recycling before its application to the soil [15,16]. Composts can be used as fertilizers because during composting, organic matter decomposes to produce a high nitrogen content [5] and reduce pathogens and toxic organic compounds [16 -18].…”

Background: Tannery industry produces high amounts of nutrient rich sludges that can be used as organic fertilizers. Objective: The aim of this study was to evaluate the fertilizing potential of composted tannery sludge. Methods: A pot experiment was carried out with ryegrass (Lolium perenne L.) to test two different composts: 2.0 kg dry matter (DM) tannery fatty sludge + 1.5 kg DM sheep manure + 1.5 kg DM wheat straw (Compost 1) and 2.0 kg DM tannery sludge + 1.5 kg DM sheep manure + 1.5 kg DM wheat straw (Compost 2). Five treatments, with three replicates each, were assigned: Control (C); Compost 1 at 6 t (C1-6) and 12 t (C1-12) DM ha-1; Compost 2 at 6 t (C2-6) and 12 t (C2-12) DM ha-1. Each treatment was applied in a pot and mixed with 5 kg of sieved soil (<2 mm). Results: Results showed that production of DM ranged between 1.2 t DM ha-1 for C1-6 and 2.4 t DM ha-1 for C2-12. The highest B, Na and N levels in ryegrass was observed in C2-12, with 175 mg kg-1 DM, 9 g kg-1 DM and 30 g kg-1 DM, respectively. At the end of the experiment no differences were observed between treatments for C, N, P2O5, and K2O levels. Differences were observed at Zn level ranged between 101 mg kg-1 DM for C1-6 and 71 mg kg-1 DM for C2-12. Conclusion: The C2-12 treatment was the best because induces higher DM production and nutrients in ryegrass and without dangerous concentration of heavy metals in soil. Composted waste from the tannery industry is a good source of nutrients for agriculture.

“…According to Tiquia et al (1996), there is no indication of toxicity when the GI value is greater than 80%, whereas a GI value below 30% already indicates high toxicity. Furthermore, test substances that induce a GI of less than 60% cannot safely be used in agricultural soils (Gonçalves et al 2020). 2018), the sensitivity of lettuce, regarding its root elongation inhibition parameter, is higher when compared to other plant species.…”

“…According to Leme and Marin-Morales (2009), MN formation is due to damage not repaired during cell division, or even repaired erroneously. The presence of micronucleate cells is considered an important marker of a mutagenic event, and for this reason, the MN assay is widely used for the detection of environmental mutagens (Sommaggio et al 2018;Gonçalves et al 2020). MN are structures similar to the nucleus, though of reduced size (Fig.…”

Among the compounds present in necro-leachate, a liquid released during the process of decomposition of the human body, are the biogenic amines cadaverine and putrescine. Although some studies on necro-leachate have indicated a potential ecotoxicological and public health risk associated with it, the research on this type of contamination is still rather limited. This study presents information about the phytotoxic and cytogenotoxic potential of cadaverine and putrescine, evaluated separately and within a mixture. Phytotoxicity was evaluated through a germination test, the initial growth of seedlings with Lactuca sativa, and cytogenotoxicity through chromosomal aberration and micronucleus tests with Allium cepa. The L. sativa results showed a phytotoxic effect for the evaluated amines, by reducing root (>90%) and hypocotyl (>80%) elongation. The co-exposure of cadaverine and putrescine potentiated cytogenotoxic activity by aneugenic action in the meristematic cells of A. cepa. From this result, it is possible to infer the eco-toxicogenic potential of cadaverine and putrescine amines and to emphasize the importance of further research in order to assess the risks of contamination generated in cemetery environments.

“…Allium cepa represents one of the main plants used in ecotoxicological tests since it can demonstrate the ability of different substances to alter DNA (Leme and Marin-Morales, 2009 ), germination, and the initial development of an organism (Fiskejö 1985 ). Notably, it has been used for the detection of contamination caused by pesticides (Souza et al 2017 ; Verma and Srivastava 2018 ; Fioresi et al 2020 ; Mota et al 2022 ), medicinal drugs (Gupta et al 2020 ; Das et al 2021 ; Eckert et al 2022 ), wastewater (Yadav et al 2019 ; Furtado et al 2020 ; Sharma et al 2021 ), and sewage sludge (Sommaggio et al 2018 ; Abreu-Junior et al 2019 ; Moraes Cunha Gonçalves et al, 2020 ).…”

Environmentally realistic concentrations of eprinomectin induce phytotoxic and genotoxic effects in Allium cepa

Eprinomectin, a veterinary drug within the family of avermectins, is widely used in the agricultural sector to combat a variety of parasites, mainly nematodes. However, only 10% of the drug is metabolized in the organism, so large quantities of the drug are released into the environment through urine and/or feces. Soil is the first and main environmental compartment to be contaminated by it, and nontargeted organisms can be affected. Thus, the present study aims to evaluate the phytotoxicity (through the evaluation of germination, root development, and germination speed) and genotoxicity (through an assessment of the induction of micronuclei and chromosomal aberrations) of eprinomectin. For the analyses, Allium cepa seeds were germinated in soil contaminated with a range of concentrations of eprinomectin: from 0.5 to 62.5 μg/g for the genotoxicity test and from 0.5 to 128.0 μg/g for the phytotoxicity test. The results showed that seed germination was not affected, but root development was affected at concentrations of 0.5 μg/g, 1.0 μg/g, 4.0 μg/g, 8.0 μg/g, 64.0 μg/g, and 128.0 μg/g, and germination speed was significantly changed at concentrations of 1.0 μg/g, 4.0 μg/g, 16.0 μg/g, 32.0 μg/g, and 64.0 μg/g. Significant differences in the mitotic index and genotoxicity index were observed only at concentrations of 2.5 μg/g and 12.5 μg/g, respectively. Only the 0.5 μg/g concentration did not show significant induction of micronuclei in the meristematic cells, but the damage observed at other concentrations did not persist in F 1 cells. According to the results, eprinomectin is both phytotoxic and genotoxic, so the release of eprinomectin into the environment should be minimized.
