“…The concentration of MTE accumulated by Nerium oleander in Setif Province, Nigeria shows the rank in concentration of the elements Mn> Sb> Bi> Pb> Fe> Cu> Cd. Other studies on the concentration of MTE in the leaves of N. oleander have revealed similar results (Espinosa and Oliva 2006;Mingorance and Oliva 2006;Mingorance et al 2007;Santos et al 2019;Fliou et al 2020;Ibrahim and El Afandi 2020a).…”

“…This species is native to Algeria and popular in the urban area. The selection of N. oleander is based on a previous study on the bioaccumulation of heavy metals in this species (Santos et al 2019;Belguidoum et al 2020;Ibrahim and El Afandi 2020a and b). The selected plant is a common and typical shrub and is planted for landscape purposes in Setif.…”

“…It can survive in soils polluted by heavy metals due to its strong exclusionary behavior (Franco et al 2012(Franco et al , 2013. Showing a good capacity for bioaccumulation of Pb, Cu, Cd, Sb, and Mn (Aksoy and Ozturk 1997;Espinosa and Oliva 2006;Mingorance and Oliva 2006;Mingorance et al 2007;Santos et al 2019;Ibrahim and El Afandi 2020a and b), it is used as a biomonitor of heavy metals in Mediterranean areas. In Algeria, this species is widely distributed in urban areas.…”

Heavy metals accumulation in Nerium oleander leaves across urban areas in Setif region, Algeria

Abstract. Koucim MA, Belguidoum A, Lograda T, Ramdani M. 2021. Heavy metals accumulation in Nerium oleander leaves across urban areas in Setif region, Algeria. Biodiversitas 22: 3083-3091. Pollution by Metallic trace elements (MTE) has become one of the most serious environmental problems resulting from human activity. Plants, which are the base of the food chain, can take up MTE from the soil solution; hyper-accumulators can store high levels of heavy metals in their aerial parts at high concentrations. These plants can be used in phytoremediation. This study aimed to investigate the accumulation of MTE in the leaves of Nerium oleander to monitor environmental pollution of several areas in the province of Setif, Algeria. The samples of N. oleander leaves were collected from 20 urban areas in Setif Province. The concentrations of seven metallic trace elements (Cd, Mn, Pb, Sb, Cu, Bi and Fe) were determined using Flame Atomic Absorption Spectrophotometry (AASF). The results show that the concentrations of heavy metals in the leaves of N. oleander, in general, were very high, far exceeding the certified standard ranges. The order of MTE in the leaves was found as follows: Mn> Sb> Bi> Pb> Fe> Cu> Cd. Our findings indicate that although N. oleander showed a significant capacity to accumulate MTE, the urban areas of Setif province were highly polluted by heavy metals. The presence of metal ions in the aerial parts of the plant indicates that N. oleander is a hyper-accumulator of metals with tolerance to Mn, Sb, and Pb, and can be used as a bio-monitor. This opens up prospects for its application for soil phytoremediation.

“…The soil samples were dried, homogenized and sieved with a 325 mesh (44 μm). Next, 500 mg soil aliquots were pressed at a pressure of 2.32 x 10 8 Pa for 15 minutes in order to obtain tablets of 2.5 cm in diameter, 1.0 ± 0.5 mm thickness and at a density of 100 mg/cm 2 (Anjos el al., 2000; Santos et al, 2019).

Chemical Elements Analysis of the Soil at an Urbanization Gradient in the Atlantic Forest

The Atlantic Forest is home to the largest urban centers in Brazil, which modify various aspects of the natural quality of this forest. Soil chemical elements from three different sites in the Atlantic Forest in the state of Rio de Janeiro were analyzed: (1) the best-preserved remnant of Atlantic Forest in the state; (2) the largest urban forest in the world; and (3) an arboretum along the main vehicle route in the second-largest city in Brazil. Energy dispersive X-ray fluorescence (EDXRF) analysis detected sixteen chemical elements including nutrient components and potentially toxic elements. The urban soil had a higher concentration of heavy metals. There was a significant concentration gradient of copper and lead from the urban site to the furthest forest site. We emphasize that the results indicate potential negative consequences for the conservation of forests and wildlife of state of Rio de Janeiro.

“…They intercept pollutants from atmospheric deposition, both wet and dry, but also accumulate those from the soil (Safari et al 2018;Allahabadi et al 2017;Mukherjee et al 2016;Baldantoni et al 2014). Numerous researchers, for example, have used Nerium Oleander L. leaves (Santos et al 2019;Fernandez Espinosa and Rossini 2006), Robinia pseudoacacia leaves (Alahabadi et al 2017; Cicek and Koparal, 2004), Pine needles (Turkyilmaz et al 2018;Pająk et al 2017), etc. In Algeria, studies were carried out on HMs accumulation by Platanus acerifolia.Wil and Cupressus sempervirens L. (Maatoug et al (2007), Casuarina equisitifolia L. (Lakhdari and Benabdeli, 2012), Tamarix gallica (Krika et al 2013), Eucalyptus cladocalyx and Cupressus.…”

The tree species differed by their capacity to capture air-borne dust and to allocate trace element from contaminated soil. The aim of this study was to explore the accumulation potential of heavy metals (HMs) by F. retusa L. and its possible use for air pollution biomonitoring in urban areas. Plant material was sampled along the national roads in Constantine city (NE-Algeria), characterized by an intense traffic load. The concentrations of cadmium, copper, lead and zinc were determined in the washed and unwashed leaves. The mean concentrations of HMs decrease in the following order: Zn > Pb > Cu > Cd for both studied leaves, and were about 0.68 and 0.98 µg/g for Cd, 7.26 and 8.74 µg/g for Cu, 20.35 and 37.61 µg/g for Pb and 63.33 µg/g and 75.94 µg/g for Zn, for washed/unwashed leaves respectively. The studied metal contents were significantly higher than those cited in the literature; this indicates the traffic road impact on HMs emissions and uptake by plants. Higher values of metal accumulation index (MAI) indicate the effectiveness of the studied species for monitoring air metallic pollution in urban areas, and its usefulness for phytoextraction of HMs from the polluted soils and/or air. Results of this study could be beneficial as preliminary reference values for HMs uptake by F. retusa in urban environments.
