This study was conducted to determine the soil contamination and the accumulation of arsenic (As) and heavy metals including chromium (Cr), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) in 15 native and cultivated plant species in a Pb recycling area of Dong Mai village, Hung Yen Province, Vietnam. The analysis of 32 soil samples collected from seven different sites in the study area revealed that the contents of Al, Fe, As, Cr, Cu, Zn, Cd, and Pb in the soils ranged from 6200–32,600, 11,300–55,500, 5.4–26.8, 24.9–290, 66.0–252, 143–455, 0.71–1.67, and 370–47,400 mg/kg, respectively. The contents of As, Cr, Cu, Zn, Cd, and Pb in rice grains and the shoots of 15 plant species ranged from 0.14–10.2, 1.00–10.2, 5.19–23.8, 34.7–165, 0.06–0.99, and 2.83–1160 mg/kg-dry weight (DW), respectively. Hymenachne acutigluma (Steud.) Gilliland, a potential hyperaccumulator of Pb (1160 mg/kg–DW), is considered the best candidate for phytoremediation of Pb-contaminated soil. The cultivation of rice and vegetables, and the use of some native plants for food for humans, pigs, and cattle should be managed with consideration of the accumulation of Pb in their aboveground biomass.

The Impact

Two plant species including Polygonum hydropiper L. and Hymenachne acutigluma (Steud.) Gilliland were investigated in their resistance to lead (Pb) and cadmium (Cd) pollution in the soil. Lead-contaminated soil samples were collected from the lead recycling village Dong Mai, Chi Dao commune, Van Lam district, Hung Yen province, Vietnam that had Pb level up to 192,185 mg.kg-1, dry weight (DW). Cadmium-contaminated soil samples were due to supplement of CdCl2.21/2H2O to alluvial soil. Results showed that both species were highly resistant to Pb, however P.hydropiper was better. Similarly, the Cd resistance was higher for P.hydropiper than for H.acutigluma. No morpho-abnormalities of P.hydropiper regarding the impact of lead were recorded, whereas for H.acutigluma, the young leaves had white colour after two months of planting in soil containing lead levels of 192,185 mg.kg-1. The response of both species with Cd in soils included yellowing leaves, withering branches and even dying after 5-15 days exposed to Cd. Lead contents accumulated in above-ground parts of both plants were up to 4,650 and 3,161 mg.kg-1, DW, corresponding to P.hydropiper and H.acutigluma. From the research results on lead resistance and accumulation of two plant species studied, it is suggested that the two species are lead hyperaccumulators can be used for phytoremediation technology to clean contaminated soil.

Levels of lead, cadmium, and nickel in roadside soils and vegetables along a  major highway in Gazipur, Bangladesh were investigated. Soil samples were  collected at distances of 0, 50, 100, and 1000 m (meter) from the road. The  concentrations of lead (Pb) and nickel (Ni) in soil and vegetables (bottle gourd  and pumpkin) decreased with distance from the road, indicating their relation to  traffic and automotive emissions. The concentration of cadmium (Cd) was found  to be independent of distance from road. There were significant differences in  the concentrations of lead, cadmium, and nickel for different plant species and  soils at various distances. The heavy metals contents both in the soils and  vegetables for every distance from the road was found in the order  nickel>lead>cadmium. DOI: http://dx.doi.org/10.3329/bjar.v37i1.11170 Bangladesh J.

Metal Levels

Various industrial activities contribute heavy metals to terrestrial ecosystems. In order to evaluate the soil quality of industrial areas and to identify the potential phytoremediator from the native plant species, we collected 45 surface soil samples and 21 plant species in a typical industrial area of northwestern China. The results showed that the average values of the Cd, Cr, As, Pb, Cu, and Zn in the soils were 36.91, 1.67, 7.20, 1.38, 1.27, and 6.66 times, respectively, compared with the corresponding background values. The average single factor pollution index for heavy metals decreased in the order of Cd > As > Zn > Cr > Cu > Pb. The study area was seriously polluted by Cd and As, slightly polluted by Zn, and had relatively little contamination by Cr, Pb, and Cu. In terms of the average Nemerow synthetic pollution index in every sampling site, 97.78% of the samples were seriously polluted and 2.22% of the samples were moderately polluted, which indicated that almost all of the samples in the industrial area were seriously polluted. The results of the biomass, heavy metal concentrations, bioconcentration factors (BCF), and translocation factors (TF) for the native plants showed that Achnatherum splendens for metal Cr presented a phytostabilization potential, Artemisia scoparia and Echinochloa crusgalli for metal Cu and Halogeton arachnoideus for metal Zn presented a phytoextraction potential, and all of the studied plants were limited as phytoremediators for Cd or Pb contaminated soil.

Assessment of heavy metal content in litchens and soil samples from various localities of Hosur Road, Bangalore south was undertaken. Topsoil samples (0-10 cm) were taken at various locations, the metals analysed were Cr, Pb, Fe, Zn, Ni and Cu. The geoaccumulation index of these metals in the soils under study residential areas indicated that they are uncontaminated with Ni, Zn, and Fe and moderately contaminated with Cr and Pb. In Industrial areas and traffic junctions the concentration of Fe, Pb and Ni was maximum. Heavy metal accumulation in few prominent lichens of some localities was analysed. Cr and Pb were maximum inChrysothrix candelaris(L.) Laundon, at the gardens of Madiwala and Silk Board junction with 95.29 and 623.95 µg g–1dry weight respectively. Fe and Cu were maximum inBulbothrix isidiza(Nyl.).

Abstract The paper presents the research results for the soils sampled from the area located in the eastern part of the Chodzieskie Lakes, between the Middle Noteć River Valley and the Wełna River Valley, the right tributary of the Warta River. The research involved 7 soil samples from the surface horizons, allocated to the cultivation of various plant species (cereals and vegetable crops). The following were determined in the soil material: the content of phytoavailable forms of selected heavy metals Zn, Cu, Pb, Ni, Fe and Mn, active and available to plants phosphorus against the activity of selected oxydo-reduction and hydrolytic enzymes. The soil under the vegetable crops showed a very high richness in phosphorus available to plants, which must have been related to an intensive fertilisation. There were identified relatively low contents of the available forms of the heavy metals investigated, the fact that points to their natural content in soil, which triggered the inhibition of neither the oxydo-reduction nor hydrolytic enzymes.

The studies conducted from 1997 to 1999 in a vegetation hall were performed as a pot experiment on ordinary silt soil. Jerusalem artichoke, maize, Sida hermaphrodita Rusby, amaranth and hemp were used as indicator plants. The results confirmed, great diversification of the element contents which depends not only on the species but also on the part of individual plants. Analysis of the data revealed also another dependence: increased concentration of heavy metals in the soil corresponded to a higher content of heavy metals in the plants. Significant differences in this respect were observed for the plant species grown in unpolluted or differently contaminated soil.

This paper considered the toxicity assessment of some crude oil contaminated soils in Niger Delta areas. The soil samples were collected from different horizontal distances, vertical depths and contaminated soil of different ages. The heavy metals in the contaminated soils were digested and extracted using di-acid digested and DTPA extraction methods respectively. The physiochemical parameters (moisture content, pH, N, P and heavy metals (Ni, Pb and Cd) were analysed with APHA method. The heavy metals concentration was determined using atomic absorption spectrophotometer (AAS). The results show that the metals concentration decreased with the age of the contaminated soil and with increased vertical depths. However, the metals concentrations were almost constant at different horizontal distances. Similar trend was observed for the moisture content, pH, N, P and K.

We compared the effects of the invasive plant Alliaria petiolata (garlic mustard) and 2 native plants on soil bacterial communities in a mature mesophytic forest. Soil samples were collected from plant patches containing either Alliaria or the native plants Allium tricoccum (wild leek) and Gallium triflorum (bedstraw). Since Alliaria litter contains secondary compounds that have reported antimicrobial properties, soil was collected outside the root zone of the plants but within the plant patches such that the soil would have been influenced by the litter of the respective plant species but not by plant roots. DNA was extracted from the soil samples and used to amplify the 16S rRNA gene region using bacterial specific primers. Terminal restriction fragment length polymorphism (TRFLP) profiles of each bacterial community were used to examine differences in bacterial communities among the plant species and between August and April sampling. Bacterial richness, evenness, and diversity were not significantly affected by plant species. Non-metric multidimensional scaling (NMS) suggested that differences existed between August and April sampling, but that plant species litter exerted a much weaker effect on soil bacterial communities. Soil physiochemical conditions were significantly correlated with soil bacterial communities and may underlie the observed seasonal changes in bacterial communities.
