Multi-matrix environmental monitoring to assess heavy element distribution around a municipal solid waste landfill in Italy

Abstract

Multi-matrix environmental monitoring was used to evaluate the influence of a municipal solid waste landfill (Ginestreto, Emilia Romagna, Italy) on the level and distribution of heavy elements in the surrounding environment (air, soil and soil biota). Concentrations of As, Cd, Co, Cr, Cu, Hg, Ni, Pb, Sb, Tl and Zn were measured by inductively coupled plasma-mass spectrometry in transplanted lichens, topsoils and isopods. The highest accumulation levels found for Cd, Cr, Pb, Sb and Zn in lichens transplanted within the Ginestreto landfill. However, similar concentrations of these heavy elements were also found in lichens exposed in monitoring sites influenced by other man-made sources, such as vehicle traffic and truck movements. The fallout of heavy elements emitted by the landfill had low impact on their levels in topsoil: Cd, Cr, Pb, Sb and Zn showed higher contents in topsoil collected close to the landfill and a slight decrease in concentrations with increasing distance from the landfill. There was no variation in heavy element accumulation in isopods in relation to distance from the landfill. The results of this study indicate that the Ginestreto municipal solid waste landfill had limited impact on the environmental distribution of heavy elements, since accumulation and enrichment in lichens and topsoils were only detected close to the landfill, up to about 100 m from its border

“…The first phase was to develop a sampling plan and work protocol inspired by previous studies, where samples were collected at variable distances from the stress source (Mazzeo et al 2013 ; Nannoni et al 2015 , 2017 ).…”

Distribution Characteristics, Pollution Assessment, and Source Identification of Heavy Metals in Soils Around a Landfill-Farmland Multisource Hybrid District

“…It can be seen in Table 1 that the average contents of Cr, Cu, Ni, Pb, and Zn (67.77, 23.32, 27.62, 24.71, and 63.07 mg kg -1 , respectively) in soils around the landfill studied (4300 t/d) were significantly higher than those near a landfill in Vientiane, Laos (300 t/d) (Vongdala et al 2019), which might be associated with the greater daily waste disposal capacity of the landfill studied herein. In addition, soil near the landfill studied (8 years in operation) contained lower concentrations of Cr, Cu, and Ni than soils around a municipal solid waste landfill in Pilsen, Czech (21 years in operation; 77.16, 48.41, and 41.47 mg kg -1 , respectively) (Adamcova et al 2016), the Laogang Landfill in Shanghai, China (23 years in operation; 86.00 and 34.00 mg kg -1 for Cr and Ni, respectively) (Liu et al 2013b), and the Ginestreto municipal solid waste landfill in Italy (22 years in operation; 89.00, 25.50, and 54.80 mg kg -1 , respectively ) (Nannoni et al 2017), which might be a result of the shorter time in operation. A previous study (Chang et al 2007) reported that heavy metal pollution tends to be more serious in landfills that have been operating for longer periods of time.…”

“…Atmospheric deposition is a significant factor affecting the distribution of Hg (Gan et al 2019). Due to its high volatility, Hg easily migrates to topsoil through atmospheric deposition (Nannoni et al 2017;Lv 2019). Thus, factor 4 may be associated with atmospheric deposition of landfill gas.…”

“…First, heavy metals could migrate with surface runoff (Yusof et al 2009), such as seeping into surrounding soils. Heavy metals in waste gases derived from landfills could also migrate into topsoil via atmospheric sedimentation (Nannoni et al 2017).…”
