Potential of trees leaf/ bark to control atmospheric metals in a gas and petrochemical zone

Adsorption of Lead and Arsenic Ions from Aqueous Solution by Activated Carbon Prepared from Tamarix Leaves

“…Low‐cost adsorbents such as agricultural wastes, clay, and biomass have also been utilized in removal of heavy metal ions from aqueous solutions because of their observed high adsorption efficiencies . Activated carbon is one of the most widely used adsorbents in wastewater treatment researches, since it can be prepared from the leaves of plants . The activated carbon prepared from the leaves of Tamarix tree, which is applied in this work in wide range of operating conditions, can be considered as a new and natural bio‐adsorbent species.…”

Ficus retusa L. as possible indicator of air metallic pollution in urban environmentSahli Leila, Belhiouani Hadjer

“…In general, the trunk diameter and height of F. retusa were 19.5 to 30 cm and 3 to 3.5 m. For sampling, leaves with identical length, fully expanded, and with no spots, and abnormal or imperfection appearance (chlorosis, necrosis, insect infestation) were considered as sample. Trees with unusual leaf such as wrinkled or yellow leaf must be excluded (Safari et al 2018). Leaves sub-samples were bulked to obtain a representative sample for each investigated site.…”

“…Of the numerous air pollutants, HMs have received great attention because of their non-biodegradable, and persistent nature, as well as toxic and disruptive effects on living organisms even at low concentrations (Gholizadeh et al 2019;Gautam et al 2016). Over the past decencies, the use of plants for HMs pollution monitoring has drawn considerable attention of scientists' worldwide (Safari et al 2018;Birke et al 2018;Mukherjee et al 2016;Serbula et al 2013;Fowler et al 2009;Malandrino et al 2006;Gerdoll et al 2000;Tyler 1990). The use of plants as a passive sampler in biomonitoring has the advantage of high spatial and temporal distribution and a low sampling cost (Sawidis et al 2011).…”

“…However, in highly contaminated environments, particularly in urban areas where anthropogenic pressure is high, we often see the scarcity or even the total disappearance of these organisms. Thus, higher plants that persist can be used for air quality biomonitoring (Safari et al 2018;Allahabadi et al 2017;Mukherjee et al 2016;Al-Khashman et al 2011;Gratani et al 2008;Berlizov et al 2007;Malandrino et al 2006;Tomasevic et al 2005;Dongarra et al 2003;Pacheco et al 2002). In urban areas, trees acts as a real pollutant sink.…”

“…The leaves of trees have been widely used as indicators of air metallic pollution than other parts of the tree like barks, buds, owers, and needle, due to their ability to absorb pollutants through stomata and cuticles. 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.…”
