“…According to WHO (2006), the concentrations of toxic chemicals vary from place to place, depending on their sources discharge of effluents into the wastewater and extent of treatment prior to heavy metal concentrations in the leaves and seeds of fibre crops grown on heavily polluted soil have been found to be lower than concentrations present in soil (Angelova et al, 2004). The differences in the concentrations in the lettuce irrigated with different water sources and that of the soils depends on the physical and chemical nature of the soil and absorption capacity of each metal by the vegetable and these are usually considered to be influenced by various factors such as the environment and human interference (Zurera et al, 1989). The high levels of heavy metals observed in the irrigated soils are an indication of the fact that the site where the study was carried out had been contaminated or polluted with heavy metals.…”

An assessment of some heavy metals concentrations in lettuce in irrigated with waste water in Tamale Metropolis in Ghana has been carried out. Analysis of water and lettuce samples revealed that the mean concentrations of Fe, Mn, Cu, Zn, Cd and Pb in lettuce were 0.436, 0.345, 0.068, 0.017, 0.04 and 0.038 mg/L and 0.167, 0.163, 0.104, 0.127, 0.142 respectively. With exception of Mn and Cd, the concentrations of heavy metals in the irrigation water, irrigated soils and irrigated lettuce, were within the FAO recommended levels. The mean concentrations of nutrients (NO 3 -N, SO 4 and PO 4 -P) in the wastewater-irrigated lettuce, and well water-irrigated lettuce were 15.36, 0.88, 0.28 and 19.09, 1.117, 0.0573 respectively. Though, heavy metals concentrations in the lettuce were low, regular monitoring are required to prevent heavy metal accumulation with their attendant health implications in the consuming public.

Gardens near the lead and zinc smelter plant "Zletovo" in the town of Veles, Republic of Macedonia, are the main suppliers with vegetables and fruits for the residents of this town. This area, was exposed thirty years to high environmental contamination with heavy metals (Cd, Pb and Zn). The smelter plant was a major source of heavy metals pollution in the environment, including the garden soils used for the production of vegetables and fruits. The aim of this study is to determine the level of contamination (especially with Cd, Pb and Zn) in green garlic (Allium sativum) and green onion (Allium scallion) produced on the contaminated soil and to determine its level of accumulation in the plants. The contents of 21 elements (Ag, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, Sr, V and Zn) in the vegetables and corresponding soils were analyzed by inductively coupled plasma -atomic emission spectrometry (ICP-AES) after microwave digestion. It was found that the contents of Cd, Pb and Zn in the vegetables from all of the four studied gardens is over the maximum permissible level according to the Macedonian regulations. The content of Cd in washed green garlic samples ranges from 0.60 to 2.70 mg kg -1 , for Pb from 4.30 to 6.14 mg kg -1 and for Zn from 11.7 to 29.9 mg kg -1 , while their contents in the washed green onion samples ranges from 0.77 to 2.66 mg kg -1 for Cd, from 3.98 to 5.35 mg kg -1 for Pb and from 21.2 to 38.0 mg kg -1 for Zn.

“…Waters of such rivers have often been reported to be polluted by heavy metals (Mashauri & Mayo 1990;Kashem & Singh 1999;Othman 2001). The extent of absorption of the elements by the plant depends on, among other things, the nature of the plant, chemical constitution of the pol-828 K. Gupta et al lutant, concentration of the element in the soil, pH and the interaction with other metals (Zurera-Cosano et al 1989). The risk of contaminants accumulating in soil, environment and crops due to sewage water, fertilizer and pollutants is of serious concern.…”

The present study was conducted to determine the culturable bacterial profile from Kestopur canal (Kolkata, India) and analyze their heavy metal tolerance. In addition to daily sewage including solid and soluble wastes, a considerable load of toxic metals are released into this water body from industries, tanneries and agriculture, household as well as health sectors. Screening out microbes from such an environment was done keeping in mind their multifunctional application especially for bioremediation. Heavy metals are major environmental pollutants when present in high concentration in soil and show potential toxic effects on growth and development in plants and animals. Some edible herbs growing in the canal vicinity, and consumed by people, were found to harbour these heavy metals at sub-toxic levels. The bioconcentration factor of these plants being <1 indicates that they probably only absorb but not accumulate heavy metals. All the thirteen Grampositive bacteria isolated from these plants rhizosphere were found to tolerate high concentration of heavy metals like Co, Ni, Pb, Cr, Fe. Phylogenetic analysis of their 16S rDNA genes revealed that they belonged to one main taxonomic group -the Firmicutes. Seven of them were found to be novel with 92-95% sequence homology with known bacterial strains. Further microbiological analyses show that the alkaliphilic Bacillus weihenstephanensis strain IA1 and Exiguobacterium aestuarii strain CE1, with selective antibiotic sensitivity along with high Ni 2+ and Cr 6+ removal capabilities, respectively, can be prospective candidates for bioremediation.
