“…Widely used ecotoxicological methods include organisms from all levels of the food-chain, e.g. aquatic organisms for waste-water or leachate assessment (Quilici et al 2004), earthworms for soil contamination assessment (Quilici et al 2004;García-Gómez et al 2014a;Curieses et al 2016), snails for contaminated area assessment (Dallinger et al 2004). One of the varieties of ecotoxicity tests is based on the use of plants, these are called phytotoxicity tests.…”

The study assesses the contamination, classification and phytotoxicity of foundry waste. The presented results are a part of the research on the agrotechnical use of foundry waste. Landfilled foundry waste (LFW) and dust samples were taken from one of the Polish foundries. An analysis of the waste and its leachate composition was conducted. Phytotoxicity tests were carried out using Lepidium sativum. The aim of the phytotoxicity study was to evaluate germination and root growth after 72 h and the accumulation of heavy metals after 7 days. LFW was least contaminated with heavy metals and metalloids compared to dust. The composition of the foundry dusts depended on the unit of the foundry, from which it was collected. It was found that electric arc furnace dust (EAFD) was the most polluted by heavy metals among the dust samples. According to the requirements of Polish regulations most of tested waste were classified as non-hazardous, and EAFD as hazardous waste due to high Pb concentration in leachate. Phytotoxicity tests have shown a low phytotoxicity of the leachate from most of the tested waste. The results of the accumulation test showed that an excess of metal and metalloids in leachate was not directly related to its accumulation in plants. A negative correlation between EC, Cu, Co, Fe, Pb, Cr, K, Na, sulfate, fluoride, ammonia, phenol and formaldehyde concentration in leachate and GI was found. It was stated that the Fe, Mn, As and Se in plants was significantly correlated with concentrations in leachate.

“…It has been reported that the proportion of the different cellular types of coelomocytes may be related to the health and the immune earthworm responses [23,28,35]. Thus, changes in cell proportions in the coelomic fluid of organisms exposed to different pollutants can be evaluated by means of this parameter as a reliable cytotoxic biomarker, as suggested elsewhere [15,37,38]. In agreement, it has been demonstrated that eleocyte proportions of another oligochaeta Dendrobaena veneta decreased after exposure to cadmium and copper [36].…”

The organophosphorus herbicide glyphosate (GLY) and the organophosphate insecticide chlorpyriphos (CPF) are key pesticides in modern management cultures worldwide. Sublethal toxicity of the commercial herbicide formulation Roundup® and the insecticide formulation Terfos® were evaluated on Eisenia fetida coelomocytes exposed under in vivo and ex vivo laboratory conditions. Induction of DNA single-strand breaks evaluated by the single cell gel electrophoresis assay and coelomocyte viability as well as alterations in coelomocyte trophic indexes were employed as endpoints for genotoxicity and cytotoxicity, respectively. Specimens were exposed at concentrations corresponding to recommended pesticide field application rate, and endpoints were evaluated after 7 and 14 days of treatment (in vivo exposure). In addition, coelomocytes were exposed to aqueous leachate of pesticide-contaminated soils during 1 h (ex vivo exposure). Earthworms exposed to Roundup® and Terfos® showed an increased frequency of DNA damage. Also, a decrease of coelomocyte viability and decrease of trophic indexes were observed in all treatments. The results demonstrate that either GLY-and CPF-based formulations exerted genotoxic as well as cytotoxic effects in coelomocytes of E. fetida exposed in vivo and ex vivo.

“…Zhang et al [62] described different inhibition effects on the luminescent bacteria Vibrio fischeri. Curieses and co-workers [63] assessed the toxicity/genotoxicity of foundry sands on the earthworm Eisenia fetida. A comprehensive toxicological evaluation of extracts of concrete containing WFS was performed on crustacean Daphnia magna, Allium cepa (onion roots) and Eisenia fetida [64].…”

Reuse or Disposal of Waste Foundry Sand: An Insight into Environmental Aspects

et al. 2022

From a circular economy perspective, the recovery and reuse of waste plays a fundamental role. Foundries purchase hundreds of millions of siliceous sands every year to create molds and cores that give shape to the casting. These sands, after several uses, become waste that must be properly recovered or disposed of; they are called waste foundry sands (WFS). The reuse of WFS leads to a reduction in: (i) the consumption of raw materials; (ii) the emissions into the atmosphere; and (iii) the amount of waste sent to landfill—on the other hand, the impact that their use generates on the environment and human health must be carefully assessed. Leaching tests are a fundamental tool for establishing the hazardousness of a waste and its release of contaminants into the environment. This paper presents an analysis of the scientific literature regarding the chemical characteristics of WFS and their release following leaching tests carried out in the laboratory; the environmental standards adopted by the countries that have issued guidelines regarding the reuse of WFS will also be presented.
