“…Aunque no hay literatura disponible al respecto, se cree que estos contaminantes mutagénicos y cancerígenos pronunciados podrían permanecer persistentes en el medio ambiente después del compostaje de RSOU y la enmienda del suelo (Chen et al, 2018). Las materias primas utilizadas en la preparación del compost, proceden de una deficiente selección de residuos, debido a ello pueden tener un contenido significativo de metales pesados (Reyes-Pinto et al, 2020). Por otro lado, el compost, presenta en su composición fuentes enriquecidas con carbono, celulosa y sacarosa, los cuales son sustratos energéticos altamente disponibles para mejorar la actividad microbiana en sitios muy contaminados con metales pesados (Lipińska et al, 2019).…”

“…La contaminación medio ambiental específicamente por metales y metaloides, se debe principalmente a la actividad antropogénica, la creciente urbanización y el desarrollo industrial (Kumar et al, 2022). A todo ello, se suma una deficiente recolección en fuentes de residuos sólidos orgánicos urbanos que influyen en el proceso de compostaje incrementando los niveles de metales pesados por un manejo inadecuado de residuos (Reyes-Pinto et al, 2020). La eliminación de metales mediante el uso de diferentes técnicas es prioritaria, si se quiere utilizar el compost como abono orgánico en la agricultura (Ozdemir et al, 2020).…”

Fungal biomass potential: production and bioremediation mechanisms of heavy metals from municipal organic solid waste compost

The compost produced based on municipal/urban organic solid waste (RSOM/U), is a valuable resource as a biofertilizer for agriculture, gardening, forestry and especially for soil remediation, whose production contributes to sustainable development through recycling of organic matter and nutrients. However, due to the raw materials used, the compost can have a significant content of heavy metals such as: cadmium (Cd), lead (Pb), arsenic (As), mercury (Hg) and selenium (Se), and contaminants such as potentially toxic trace elements that harm human health. These components can accumulate in plant tissues by absorption, giving rise to the possibility of being bioavailable to humans and animals. The fungal bioremediation of heavy metals in RSOM/U compost is highly efficient, cost-effective, available and friendly to the environment, therefore the removal of metals through this technique is a priority, if the purpose is to use it in agricultural soils. This review summarizes the studies based on the potential of fungal biomass for the bioremediation of heavy metals in RSOM/U compost, reporting information on RSOM/U-based compost, fungal biomass production and mechanisms of bioremediation of heavy metals by fungal biomass. In conclusion, the bioremediation of heavy metals using the fungal biomass in RSOM/U compost, with adequate segregation of raw material, coupled with bioremediation, could improve the removal of heavy metals in RSOM/U compost, and could be an ecological and viable alternative, which must be valued by intensifying its use.

“…In these, it was found that anthropogenic inputs have overwhelmed the natural biogeochemical cycles of the trace elements on Earth [34]. This is partly due to the application of mineral and organic fertilizers, compost, and liming materials that contain certain amounts of metals [35][36][37][38][39]. In this research, the contents of Co, Pb, and Mo were not detected due to the higher detection limits (LOD) of the instruments (3 mg/kg for Co and Pb, and 2 mg/kg for Mo).…”

According to the Scopus database, over the last five years, 91 scientific papers with the keyword “pXRF” (portable X-ray fluorescence) were published in indexed journals in the domain of environmental science and agricultural science, which indicates more frequent applications of this technique in scientific research. The pXRF method is characterized by speed, precision, accuracy, and the possibility of a simultaneous analysis of a large number of elements, albeit with higher limits of detection (LODs) as a major disadvantage. The presence of metals in certain phosphate fertilizers is well established, though not to the same extent as in mineral nitrogen fertilizers. The aim of this research was to determine the metal content (As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Si, Sr, Th, U, Zn, Zr, and Y) in thirteen commercial mineral nitrogen fertilizers via the pXRF method. Six straight fertilizers (ammonium nitrate, ammonium sulphate nitrate, limestone ammonium, nitrate, and urea) and seven complex fertilizers (various NPK formulations), which are different even according to their production technology, produced in Croatia were analyzed using the handheld Vanta C (Olympus) XRF analyzer according to the loose powder method and “point and shoot” technique. Data quality control was performed by analyzing the reference fertilizer samples and certified and reference soil samples. The results revealed that the determined contents of Cd, Mn, and Th were relatively higher in the single-component fertilizers, while the contents of As, Cr, Fe, Ni, Si, Sr, Zn, Zr, Y, and U were relatively higher in the complex fertilizers. Due to the higher LODs of Co and Pb (3 mg/kg) and Mo (2 mg/kg), the pXRF method was not appropriate for the determination of these metals in the analyzed fertilizers. The quantified metal content in the analyzed fertilizers varied as follows: 2.0–8.0 mg As/kg; 11.5–31.3 mg Cd/kg; 29.8–118.5 mg Cr/kg; 7.8–26.3 mg Cu/kg; 16.5–2209 mg Fe/kg; 20.3–5290 mg Mn/kg; 6.2–27.8 mg Ni/kg; 1156–4581 mg Si/kg; 2.0–469.8 mg Sr/kg; 3.0–35.3 mg Th/kg; 2.0–82.8 mg U/kg; 1.4–166 mg Zn/kg; 9.7–15.3 mg Zr/kg; and 16.5–128.0 mg Y/kg. The results indicated that the pXRF method is particularly suitable for measurement and metal detection in complex nitrogen mineral fertilizers with higher amounts of metals, but it is not suitable for the detection and quantification of the lower amounts of As, Zr, Y, Cu, Ni, and Cr in single-component nitrogen fertilizers. Compared to all of the investigated fertilizers, the highest amounts of As, Cr, Cu, Fe, Ni, U, Zn, and Zr were quantified in the NPK 7-20-30 formulation.
