Abstract

Barberry is well known and naturally adapted in Iran, and it has been extensively used as a medicinal plant in traditional medicine. The fruit of the barberry is used in medicine to treat liver, neck and stomach cancer, for purification of the blood and for breath freshness. Iran is the main center for distribution of genus  Barberry vulgaris and Barberry integerrima and one of the richest countries in the world as regards genetic resources of medicinal and wild unknown  plants that some of them are export  . We have studied on potential ability of Barberry integerrima residue potential as an adsorbent of heavy metal . B. integerrima barberry fruits were collected in 2015 from Qaen  in south Khorasan province in the north-east of Iran and put in contaminated soil samples by heavy metals. Aerial parts of growing coriander in every ten days in companion of B. integerrima  fruits residue in the soils  were separated in 30 days and digested by wet method according the standard protocol  for measuring Cadmium ,Chrome (III) and (VI)  , Nickel and Lead. Mean values were calculated, and analysis of variance (ANOVA) and Student’s t-test were performed. The results of present study revealed adsorption capacity of Cr (VI), Cr(III), Pb and Cd  by barberry residue was investigated in a batch system by considering the effects of various parameters like contact time, initial concentrations, pH , temperature, absorbent dose. The results of this study revealed that B. integerrima fruit barberry residue  can accumulate high level of lead, Cadmium and  Chrome (VI) and (III)   in a short time and their uptake rate by vegetable and edible plant is significantly affected by their concentrations in the contaminated soil (p<0.05). A contact time of 10 days   by B. integerrima was found to be optimum and 89.2% Cr (VI), 78.9% Cr(III), 95.6% Pb and 43.6% Ni  was remained in soil while a few amounts of these heavy metals being uptake by edible vegetable – coriander . Experimental results showed that low cost bio-sorbent was effective for the removal of pollutants from soil.

Introduction

Barberry family includes about 650 species of plants and shrubs which are often spiny. Root, stem, leaves and fruits are used in medicine and food industry. Zakaria Razi  introduced two species of barberry in his book; black barberry that grows in mountains with stronger medicinal properties and red one that grows in valleys. In Iran two important barberry species are B. Integerrima (abi) and B. Vulgaris (poloei). B. Integerrima is a thorny shrub with fragile branches to a height of 1 to 3 meters [1].

Barberry is an Iranian exclusive plant which is generally cultivated around Birjand, South Khorasan, Qaen, Tabas, Gonabad and Kashmar. The Berberis vulgaris fruit is very useful as tonic for liver and heart; it prevents chronic bleeding, reduces mucus, purifies blood, and also reduces triglycerides, cholesterol and blood pressure. In addition it is effective in treatment of gall bladder, bleeding hemorrhoids, antiparasitic liver, diabetes, gout, kidney stones, colon cancer, prostate inflammation, malaria, fever, asthma[2]  and neurological diseases [3].

B. Integerrima fruits are used to prepare juices. The use of barberry fruit as a natural food colorant rich in anthocyanins instead of harmful artificial ones was studied by researchers [4]. In natural fiber products barberry fruit’s extract used as a colorant shows a mild purple color [5]. Barberry bioactive compounds are widely used in medical and food industry [6]. Berberis integrrima (Syn: Berberis densiflora Boiss.&Buhse) is a medicinal shrub with yellow wood and obovate leaves, bearing pendulous yellow flowers succeeded by oblong red fruits. This plant belongs to the Berberidaceae and found in most regions of Iran, especially in northern and northeastern[7] .Due to having secondary metabolites such as Berberine, Oxyacanthine, Bermamine, Palmatine, Jateorrhizine, Columbamineand Berberubine, this plant has too much medicinal properties [7-9]. Barberis contain citric acid and malic acid and due to these possesses astringent, and anti scorbutic properties useful in inflammatory fevers, especially typhus, and scurvy, and in the form of a jelly, are very refreshing for irritable sore throat; syrup of berberis made with water is used as an excellent astringent gargle. The fresh juice of the fruit is also said to strengthen the gums and relieve pyorrhea when brushed on or applied directly to the gums. A decoction of the bark or berries has been found of service as a wash in aphthous sore mouth, and in chronic ophthalmia [10]. Various properties are listed for different parts of barberry plant and these properties have been confirmed in various research[11,13]. In addition to the antioxidant properties of Barberry fruit [11], a variety of alkaloids obtained from root and stem bark, which most important of them is Berberine [12]. Based on studies on barberry root extract and its main alkaloid (Berberine) these following properties are listed: Antioxidants [11],anti-inflammatory effects [12], hypoglycemia [13], hypolipidemic [14] ,collecting free radicals and finally reduction of oxidative stress [15]. However most of these studies performed in animal models and used of berberine (root and stem extract of barberry). Given that barberry fruits contain polyphenols, pectin and gum, vitamin C and malic acid [16],  the present study was designed to evaluate the effects of Berberis integerrima Bge. fruit aqueous extract on adsorbing heavy metals in contaminated soil and rescue soil for the optimum condition for growing edible vegetables and crops . Iran is the main center for distribution of genus Barberry vulgaris and Barberry integerrima . As Iran is one of the richest countries in the world as regards genetic resources of medicinal and wild unknown  plants that some of them are export  [17]. We have studied on potential ability of Barberry integerrima specie as its  endemic specie  found in some parts of Iran especially in in south Khorasan province in the north-east of Iran and its’ residue potential as an adsorbent of heavy metals in order to find an inexpensive adsorbent for the removal of Pb, Ni, Cd  and Cr from agricultural soils.

Current  research conducts adsorption of heavy metals by agricultural waste and by-product and follow low-cost environmentally friendly method for removal of heavy metals from contaminated soil.

Materials and Methods

integerrima (10 Kg) barberry fruits (ripped completely) were purchased in October 2015 from 5 gardens of Gaen in south Khorasan province in the north-east of Iran( figure 1) . To prepare the material barberry fruits were carefully purged of any branches, thorns, leaves, stones and other waste substances. Then cleaned fruits were packed in plastic bags and were kept at -18°C freezer Equipment.  To prevent discoloration and reduce effects of drying process fruits were dried in the oven at 50°C  for 48 hours for B. integerrima  fruits according to the  amounts of moisture.  Dried fruits were ground by Moulinex grinder. For 500 gram of barberry , 4liters of deionized water were added. Allowed the mixture to be soaked for about 12 hours and then boiled it for 3hours, first at 100°C  for 1 hour and then heating up to 80°C  . After cooling the heated mixture  its’ precipitations in  the extracted fruit juice of B. integerrima was filtered and  separated from colorful solution  by Quantitative Ash less Filter Paper: Whatman – Grade 41.The fruit residue were added to the studied composite  soils in 30 Coriander cultivated  vases .

Soil Sampling

A composite soil sample was collected from depth of 0-35 cm from a yard in the center of Tehran in order to simulate the conditions of soils in the contaminated lands with industrial sewages. 30, 15, 30, 25, 20, 15, 5, 20, 20,  30 and 30 mM/L of Pb(NO₃)₂, Cd (NO₃)_2,  KNO3, Zn NO₃ ,  MnSO ₄ , CrCl3,K₂ Cr₂ O_{7 ,}  K₂ SO ₄  . 5H ₂ O, CaHPO₄ and Ni SO₄ respectively and 200 g of  residue  of B. integerrima barberry fruits  and separating  (ratio 10 :1) were added. Composite soil samples (depth of 0-35 cm) were collected of Heavy metal contaminated soil by coriander  cultivated  grown   and not grown in it by different pHs after every 10 days in 30 day studying.   Metal contents were detected by Atomic Absorption Spectrophotometer by wet digestion method in Research Laboratory in Pharmaceutical Sciences Branch University.

At the beginning of study, soil profile characteristics were observed and recorded by a packet penetrometer (Cl-700A, soil Test Inc., USA). Soil samples were mixed, homogenized and separated into three parts, 1/3 of each samples was air-dried and pass through a 2 mm sieve in order to determine p and k content, pH and electrical conductivity and particle-size distribution. The other 2/3 was passed through a 2 mm sieve without drying and 1/3 of it used to determine heavy metals concentration by Atomic Absorption Spectroscopy (AAS) after digestion with aqua-regia. The samples were analyzed by an Atomic Absorption Spectrophotometer Model AA-6200 (Shimadzu, Japan) using an air-acetylene flame for heavy metals: Chrome, Nickel, Lead and Cadmium, using at least five standard solutions for each metal. All necessary precautions were taken to avoid any possible contamination of the sample as per the AOAC guidelines [18-20].

Sampling method

Aerial parts of coriander in every ten days in companion of B. integerrima  fruits residue  were separated in 30 days and washed and digested by wet method according the standard protocol  for measuring Cadmium ,Chrome (III) and (VI)  , Nickel and Lead. Bioaccumulation factors (BAF-s) were calculated for heavy metal content of plant parts (mg/kg) / heavy metal content of soil (mg/kg), for each metal [ 17].

All coriander samples were watered each day by tap water (Tehran tap water). The studied samples were managed by the same light situation and some circumstances in order to be compared with each other due to determine the ability of B. integerrima  in adsorbing  Lead, Cadmium and Nickel from soil and its potential to avoid transferring heavy  metals to coriander and keep  safe the eating vegetable .

Physical and chemical properties and concentrations of heavy metals (Cadmium, Nickel and Lead,) in soils, before and after adding B. integerrima fruit barberry residue  in the growth period of cultivated coriander were measured in every ten days.  In order to assess amount of heavy metals in the soil samples, heavy metal concentrations in soils of studied vases were determined by atomic absorption spectrophotometer [21-26].

Statistical analysis

The values reported here are means of five  values. Data were tested at different significant levels using student t-test to measure the variations between the contaminations in soil and coriander   parameters before and after treated by B. integerrima  fruit residue  . One way analysis of variance (One-ANOVA) was used for data analysis to measure the variations of metal concentrations  using SPSS 22.0 software (SPSS Inc, IBM, Chicago, IL).

Results and Discussion

Chemical extraction of the soil profile before adding specified amounts of heavy metals is shown in the table 1. Data is averages of the profiles.

Plant availability of certain heavy metals depends on soil properties such as soil pH and contain exchange capacity and on the distribution of metals among several soil fractions.  The fractionation of Pb, Cr, Ni, and Cd in coriander cultivated control soil and in soils treated by  B. integerrima fruit barberry residue  is  completely determined due to find out the adsorption ability of heavy metals by barberry residue in contaminated soil samples.

Results showed B. integerrima fruit barberry residue adsorption  for all heavy metals in treated soil were affected significantly by barberry  residue and  the residue    not only affected contaminated soil and can adsorb  lead, Cadmium , Chrome and Nickel after 10  days (p<0.001) more than other studied  but also adding barberry  residue have reduction and rescue  effect in taking up heavy metals especially in bio-adsorbing Cadmium and Nickel  more than other heavy metals studied and  it keeps edible vegetable safe for eating . In figure 2 the treating contaminated soil  trend by this residue fruit indicates that dried B. integerrima fruit parts in the soil which is enriched soil by mineral elements and vitamins, it  can be consider as a suitable method for rescuing soil  by its relatively large ratio of  biomass concentration of the contaminant  to the  soil concentration.

Chromium as a pure metal has no reported human or environmental toxicity effects. Both acute and chronic toxicity of chromium are mainly caused by hexavalent chromium compounds (Cr VI). Hexavalent chromium is considered the most hazardous of all forms, and in welding fume it is a suspected human carcinogen. DNA damage in welders has been associated with hexavalent chromium exposure [27] . This is consistent with the classification of hexavalent chromium as a human lung carcinogen [28-29]. The ratios of adsorbent/heavy metal contents  were calculated to indicate the translocation efficiency of Pb and Cr from soil  to the adsorbents while for the results of nickel translocation was not significant.  The Cr (III) concentrations in samples after 10, 20, 30 days are higher in soil  than Cr(VI), hence the translocation factor  ratios were less than one for Cr (VI) treated samples shows that this method is highly suitable for adsorbing Cr(III)  to the Cr (VI). Even though the Cr(VI), concentration of contaminated soil   of Cr treated samples in  10 days   treated samples  is higher compared to controls solutions,  the extent of metal accumulation and uptake efficiency of Cr(III) was lower than that of Cr(VI), in long term contaminated situation study.  Most of coriander vegetable samples in Cr (VI) samples deformed after 30 days remaining in contaminated soils.

The results of present study revealed adsorption capacity of Cr (VI), Cr(III), Pb and Cd  by barberry residue was investigated in a batch system by considering the effects of various parameters like contact time, initial concentrations, pH , temperature, absorbent dose. The adsorption was time and metal dependent and the maximum adsorption was observed at lead contamination. Moreover, contact time of different heavy metals in the contaminated soil showed significant (p <0.05) and positive correlation with contents of Pb (r = +89 to r = +96), Cr⁶⁺ (r = +74 to r = +81), Cr ³⁺ (r = +79 to r = +83), Ni (r = +30 to r = +36) in the contaminated soil and B. integerrima fruit barberry residue respectively. The amounts of lead adsorbed increased significantly with increase contact time (p<0.005). The results of this study revealed that B. integerrima fruit barberry residue can accumulate high level of lead, Cadmium and  Chrome (VI) and (III)   in a short time and their uptake rate by vegetable and edible plant is significantly affected by their concentrations in the contaminated soil (p<0.05). A contact time of 10 days   by B. integerrima was found to be optimum and 89.2% Cr (VI), 78.9% Cr(III), 95.6% Pb and 43.6% Ni  was remained in soil while a few amounts of these heavy metals being uptake by edible vegetable – coriander . Experimental results showed that low cost bio-sorbent was effective for the removal of pollutants from soil.

The present investigation shows that the B. integerrima residue is  effective and inexpensive adsorbent for the removal of Pb and Cr (VI) from soil.

This research conduct adsorption of heavy metals by agricultural waste and by-product and proved that this friendly method should  gain more attention and research interest for the removal of heavy metals from contaminated soil  due to its surface area, adsorption capacity and plenty abundant in nature must be followed seriously.

Also, this research suggests more investigations by other genera and families of cost-effective waste agricultural products applying as adsorbents for these heavy metals and other toxic metals such as cadmium, arsenic and Mercury.
