“…It is worthy to mention that flavedo and albedo are rich in pectin (Mamma and Christakopoulos, 2014) which can bind heavy metal ions (Kartel et al, 1999). Heavy metals are sorbed on their active functional groups (Marín et al, 2010). Thus, concentration of these metals in citrus segments seemed to be relatively low.…”

A UTOMOBILE exhausts are considered the main source of air pollution with heavy metals. Airborne pollutants are precipitated on soils surrounding highways causing serious ecological hazards. The current study aimed at evaluating levels of Pb, Ni, Co and Cd in surface (015-cm) and subsurface (1540-cm) soils nearby Cairo-Alexandria agricultural highway, and their accumulation in plants grown thereon. Seven locations were sampled at interval distances 50 meters on both sides of the highway road near Toukh city (Qualubya Governorate). Cabbage and citrus plants were also sampled and separated into its parts. Results revealed that the investigated soils are contaminated with Pb, Ni and Cd. These contaminants were brought to the subsurface layers of the soil at relatively high concentrations. Total and DTPA-extractable contents of Pb and Ni in the top surface soil decreased with increasing the distance from the high way on both sides of the road. Moreover, concentrations of these metals in the cabbage parts were significantly correlated with their total and DTPA-extractable contents. However, Co and Cd in soils seemed to be not affected by the exhausts of the cars on the highway. Heavy metals decreased in cabbage parts as follows: root > stem > outer leaves > inner leaves > core. Calculated BAF values for Pb, Ni and Co were very low indicating that cabbage might be an excluder for these metals whereas, their transfer from roots to shoots (transfer factor, Ts) were high. Heavy metal concentrations in citrus decreased as leaves > flavedo > albedo > segments. Generally, concentrations of heavy metals in plants particularly Pb exceeded the permissible limits. 19

“…Toxicity of zinc has several reversible and irreversible effects on natural flora and fauna. For example, very low exposure of zinc is responsible for gastrointestinal disturbance, i.e., irritability, nausea, loss of appetite, metal fume fever and muscular stiffness (Lesmana et al 2009;Bhattacharya et al 2006;Vilar et al 2007;Marin et al 2009). The level of zinc beyond a threshold concentration in soil affects the fertility of soil very adversely (Agorboude and Navia 2009).…”

“…The level of zinc beyond a threshold concentration in soil affects the fertility of soil very adversely (Agorboude and Navia 2009). The exposure to zinc also leads to lethargy, hyperamylasemia, pancreatitis, cholestatic jaundice, anemia, thrombocytopenia, pulmonary edema, renal failure, circulation and neurological disturbances (Klein 2000;Marin et al 2009). The concentration of 120-lM of zinc leads to the micronucleus induction in plant Vicia faba (Mishra et al 2010).…”

Massive industrialization and urbanization of civilization during the last few decades have made a thrust in heavy metal pollution in various water bodies. In past, various kinds of conventional metal ion remediation technologies, such as cementation, osmosis, reverse osmosis, ultrafiltration, etc., have been practised. However, most of these technologies are quite expensive, and lead to the generation of secondary chemical sludge. However, biosorption of heavy metal ions is significantly inexpensive and an eco-friendly technology. Among the series of heavy metals, zinc has gained the significant interest due to its toxicity and easy availability in water bodies. Biosorption of zinc in liquid phase by living, nonliving, conventional and non-conventional biosorbents has been practised extensively in the past. This literature review focuses on the recent trends practised in the field of biosorption of zinc from liquid phase. The present work provides deep insight into various aspects of biosorption of zinc by different mechanisms of biosorption, bioaccumulation, isotherm, kinetic and mechanistic modeling. An exhaustive comparison among different sorts of biomasses has also been given in the present work to enlist all the milestones of biosorption.

“…osmosis, electro coagulation and flocculation, reverse osmosis, solvent extraction, hydroxide precipitation, and membrane separation have been adopted to remove heavy metals across liquid phase [13,14]. In general, all these above mentioned technologies are expensive, lead to generation of secondary chemical sludge containing heavy metals, making the disposal of sludge questionable, and ineffective in removing heavy metals including Zn(II), Cd(II), Pb(II), Cu(II), and Cr(III) at low concentration levels ranging between 1 and 100 mg L À1 [10,[15][16][17][18][19]. Zinc is one of the elements of heavy metal series.…”

Bioremediation of Zn(II) by biosorption across aqueous phase on to surface of eucalyptus leaf powder has been investigated in present research work. The adsorptive potential of eucalyptus leaf powder was evaluated as function of pH, temperature, contact time, agitation rate and particle size. Maximum metal ion uptake and percentage removal capacity of eucalyptus leaf powder were 23.5 mg g À1 and 94%, respectively, at optimized pH 5, 20 AE 18C, contact time 6 h, particle size 0.5 mm and agitation rate 200 rpm. The biomass surface analysis revealed the fact that the biomass surface was heterogeneous and porous in nature. The functional groups like amine, amide, carboxyl, hydroxyl, and methyl groups, significantly important for metal ion binding were present on biomass surface in tremendous amount. Additionally, the Fourier transformation IR spectrum analysis of acid and base activated eucalyptus leaf biomass ruled out all the possibilities of the presence of surface functional groups mentioned above. The reaction rate was studied by applying two rate limiting models pseudo first and pseudo second order. Pseudo second order model was found to be more suitable (R 2 ¼ 0.998) in comparison to pseudo first order (R 2 ¼ 0.724). Adsorption equilibrium of batch stirred reaction data fitting shows the dominance of Langmuir isotherm (R 2 ¼ 0.99) against Freundlich isotherm (R 2 ¼ 0.887) model with equipartitional involvement of both film and intra particle diffusion as rate limiting steps at differential status of contact time.Keywords: Bioremediation; Intra particle diffusion; Langmuir isotherm; Pseudo second order reaction; Zn(II) ion IntroductionThe rapid and tremendous industrial development during last decade has increased the heavy metal pollution in environment [1,2]. Heavy metals are non-biodegradable and have tendency to get accumulated inside the human body via incorporation through food chain [3][4][5][6][7]. Major industrial operations unit like metallurgy, steel production, paint and pigment industry, copper smelting unit, acid mine drainage, electroplating, and metal finishing significantly contribute to heavy metal pollution in natural water streams [8][9][10][11][12]. Various remedial technologies/unit operations viz. osmosis, electro coagulation and flocculation, reverse osmosis, solvent extraction, hydroxide precipitation, and membrane separation have been adopted to remove heavy metals across liquid phase [13,14]. In general, all these above mentioned technologies are expensive, lead to generation of secondary chemical sludge containing heavy metals, making the disposal of sludge questionable, and ineffective in removing heavy metals including Zn(II), Cd(II), Pb(II), Cu(II), and Cr(III) at low concentration levels ranging between 1 and 100 mg L À1 [10,[15][16][17][18][19]. Zinc is one of the elements of heavy metal series. Though zinc is an essential element of life but its exposure beyond permissible limit, defined by United States Environmental Protection Agency, World Health Organization, Canadian Wate...
