“…The mean Cr concentration in sugarcane juice sampled in Réunion (0.05 mg kg − 1 FM) was lower than the levels measured by Bertoncini et al (2004) (0.5 mg kg − 1 FM) and by Mohamed (1999) (0.075 mg kg − 1 FM) at unpolluted sites. In stems, only two studies (Muchuweti et al, 2006;Segura-Munoz et al, 2006) reported Cr concentration ranges for metal-polluted sites: Cr concentrations in stems ranged from 11.9 to 232.9 mg kg − 1 (SeguraMunoz et al, 2006), whereas our findings ranged from 0.25 to 0.9 mg kg − 1 . For Pb and Ni, the few available data were higher than those measured in Réunion.…”

“…For the analysis of soil samples, the "Aqua Regia Metal Extraction Method" (HNO 3 :HCl, 3:1) was used in Teflon pumps. Approximately 1 g of each sample was weighed, and 10 mL of "Aqua Regia" were added [8]. For analysis of vegetables, about 2 g of vegetable in nature were weighed and 10 mL of nitric acid (Suprapur) added.…”

This study aimed to evaluate the viability of using treated residuary water from the Biological Wastewater Treatment Plant of Ribeirão Preto to grow vegetables, through the characterization and quantification of parasites, coliforms, and heavy metals. Three equal cultivation areas were prepared. The first was irrigated with treated/chlorinated (0.2 mg L(-1)) wastewater, the second one with treated wastewater without chlorination, and the third site with potable water, which was the control group. The presence of Hymenolepis nana, Enterobius vermicularis, nematode larvae, and Entamoeba coli was verified in lettuce (Lactuca sativa) samples. Although nematode larvae were observed in rocket salad (Eruca sativa L.), no significant differences were found between the number of parasites and type of irrigation water used. No significant differences were found between the number of fecal coliforms in vegetables and the different types of irrigation. However, the vegetables irrigated with treated effluent without chlorination showed higher levels of fecal coliforms. The risk of pathogens is reduced with bleach addition to the treated effluent at 0.2 mg/L. Concentration of heavy metals in vegetables does not mean significant risks to human health, according with the parameters recommended by the World Health Organization.

East Calcutta Wetland (ECW) is an example of wise use of cities solid and liquid waste through integrated resource recovery, mainly for pisciculture, vegetable as well as paddy cultivation and manure production. Amaranthus caudatus, Amaranthus blithum and Spinacia oleracea grown at ECW were analyzed for their accumulation of elements using Energy Dispersive X Ray Fluorescence (EDXRF) and compared to those grown in south eastern parts of West Bengal (Midnapur). The objective was to analyze the health hazard, if any, underlying the use of wastewater and solid waste for cultivation of green leafy vegetables at ECW. The following results were obtained upon comparing the data collected from the two different sites: (a) higher accumulation in ECW grown plants of elements like Ca, Cu and Pb in Amaranthus caudatus; of Ca in Amaranthus blithum; of Cl and Cu in Spinacia oleracea, (b) for the same species grown in non-ECW site, higher concentration of elements like Mn and Fe in Amaranthus caudatus; of Cl, Mn and Br in Amaranthus blithum; of Ca, Mn, Fe and Br in Spinacia oleracea. The net consumption of the aforementioned elements per person per day was calculated and found to be much below the Recommended Dietary Allowance (RDA) levels in all cases. Thus the vegetables grown out of integrated resource recovery mechanism at East Calcutta Wetland appear to be safe for human consumption. This further corroborated by the healthy appearance of these vegetables. This result has profound implications of far reaching significance for environmental management and health economics.
