Heavy metal contents, soil-to-plant transfer factors, and associated health risks in vegetables grown in western Iran

This study estimated the concentrations of heavy metals in regularly consumed sour, sweet and homemade traditional yogurts in Bangladesh. A total of 300 yogurt samples (sour, sweet and homemade traditional); 100 yogurt samples of each category were considered for this assay. To assess the health risks, the daily yogurt consumption rate and the value of target carcinogenic and non-carcinogenic risks of these yogurt samples were also determined. In sour yogurt samples, detected heavy metal contents were 0.398±0.121 mg/kg, 0.774±0.372 mg/kg, 0.087±0.021 mg/kg, 0.131±0.026 mg/kg, 0.011±0.006 mg/kg, 0.031±0.005 mg/kg, 0.445±0.267 mg/kg and 0.029±0.024 mg/kg while in sweet yogurt samples, detected heavy metal contents were 0.410±0.146 mg/kg, 0.704±0.324 mg/kg, 0.082±0.028 mg/kg, 0.146±0.025 mg/kg, 0.010±0.005 mg/kg, 0.030±0.007 mg/kg, 0.460±0.265 mg/kg, and 0.035±0.026 mg/kg and in homemade traditional yogurt samples, detected heavy metal contents were 0.410±0.147 mg/kg, 1.502±0.367 mg/kg, 0.085±0.020 mg/kg, 0.120±0.024 mg/kg, 0.011±0.005 mg/kg, 0.020±0.005 mg/kg, 0.251±0.174 mg/kg and 0.025±0.021 mg/Kg for Iron (Fe), Copper (Cu), Manganese (Mn), Zinc (Zn), Lead (Pb), Cadmium (Cd), Chromium (Cr) and Arsenic (As) respectively. Among the analyzed heavy metals, highest concentration of Cu and lowest concentration of Pb was detected in all yogurt types. The values of estimated daily intake (EDI), Target hazard quotient (THQ), Total THQ (TTHQ) and Target Carcinogenic risk (TCR) confirmed that, there have no chances of any kind of carcinogenic and non-carcinogenic risks from these yogurt samples.

According to the field investigation, collecting five kinds of dominant plant from tin ore tailing reservoir of Gejiu and tailing reservoir soil samples by flame atomic absorption spectrometry for the determination of five kinds of dominant plant roots, stems, leaves and its growth soil’s Pb, Zn, Cu and Cd contents, and analyzes five kinds of plant transfer and accumulation coefficient. The results showed that: soil heavy metal pollution is serious, especially Cd pollution; Lactuca indic L、Cattail、Alopecurus aequalis and Cyperus rotundus L. plants of heavy metal contents are the same, all is Zn﹥Cu﹥Pb﹥Cd, but four kinds of heavy metal contents are Pb﹥Zn﹥Cu﹥ Cd in Neyruadia plants; Lactuca indic L、Cyperus rotundus L、Alopecurus aequalis and Cattail to Pb, Zn, Cu and Cd four kinds of heavy metals accumulation ability is weaker. But from the root to the ground part organ transfer ability aspects: four kinds of heavy metal in Lactuca indic L is strong, Pb and Cd two elements in the Cyperus rotundus L is more stronger, Cd in Alopecurus aequalis is more stronger, Zn, Cu and Cd in Cattail is more stronger; the accumulation and transfer coefficient are larger than one, it was a better plant which removes Pb.

Heavy metals naturally are non-biodegradable constituents of the earth’s crust that accumulate and persist indefinitely in the ecosystem as a result of both human and natural activities. Their contamination of vegetables remains an issue of public health interest due to the frequency, and quantity of consumption. The over exposure to these heavy metals continues to pose serious health threat globally. This study was aimed to assess the heavy metal contents of staple vegetables [Telfairia occidentalis, Amaranthus hybridus and Ocimum gratissimum] within Enugu metropolis; the leaves were screened for heavy metals [Arsenic As, Lead Pb, Cadmium Cd, Nickel Ni, Chromium Cr and Cobalt Co], by atomic absorption spectroscopy (AAS). Results (Mean±SD, mgkg-1 ) showed that Amaranthus hybridus: contained [Pb-0.109±0.350, Cr -0.161±0.004]; Ocimum gratissimum: [Ni-0.179±0.028, Cd-0.033±0.006, Cr-0.176±0.036], and Telfairia occidentalis: [Pb-0.153±0.139, Co-0.198±0.148]; of which some values were slightly above WHO/FAO standards. Although, the estimated daily intakes (EDIs) were below referenced tolerable daily intakes (TDIs). The hazard quotients (HQs) were below 1 (HQ<1), but As and Cd, were exceptions; while the hazard index (HI) values were all above 1 (HI>1). The slightly above standard references of some of these heavy metals, and HI>1 values in this study are a concern, as potential health risks may arise amidst the population over a period of time, therefore, there is need to eliminate the likely sources of the latent contamination.

Vegetables growing in mining areas have become a serious food safety concern because of the high levels of heavy metals always associated with mining. In this study, water used for irrigation, soil, cabbage, green pepper and green beans grown in tin mine areas of Heipang District, Barkin-Ladi LGA of Plateau State were analyzed for lead, cadmium and zinc, using Atomic Absorption Spectrophotometer (AAS). The concentrations of the heavy metals in water, soil, vegetables were all in the order Pb, >> Cd > Zn. In the vegetables, the order was: Pb → cabbage > green beans > green pepper; Cd → green beans > cabbage > green pepper; Zn → cabbage > green pepper = green beans. The transfer factors for all the metals (heavy metal in plant / heavy metal in soil) ranged from 0.95 to 1.48. There were high levels of Pb and Cd in all the vegetables, which may be attributed to the metals in the water used for irrigation. Whilst the concentration of Zn in all the samples were lower than recommended limits, the levels of Pb and Cd in the water, soil and vegetables were higher than the WHO/FEPA standard recommended limits reported for vegetables. The Cd concentrations of the vegetables also exceeded the tolerance thresholds for animals and human beings and therefore consumption of vegetable from the area would endanger the health of the population.
