Integrated Resource Recovery at East Calcutta Wetland: How Safe is These?
TLDR
In this article, the authors analyzed the health hazard, if any, underlying the use of wastewater and solid waste for green leafy vegetables at East Calcutta Wetland (ECW) and compared to those grown in south eastern parts of West Bengal (Midnapur).Abstract:
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.read more

Accumulation of heavy metals by vegetables grown in mine wastes.
TL;DR: In this paper, the metal concen- trations were found to be heterogeneous in mine wastes and in soils mixed with mine wastes, and four plant species, namely iceberg lettuce, Cherry Belle radishes, Roma bush beans, and Better Boy tomatoes, were investigated.

Influence of fertilizer and sewage sludge compost on yield and heavy metal accumulation by lettuce grown in urban soils.
TL;DR: Comparing garden vegetables and soil as potential sources of Pb risk to children, it is clear that the risk is greater through ingestion of soil or dust thanThrough ingestion of garden vegetables grown on the soil.

TL;DR: The results of this study indicate that sugar cane is a crop that is able to grow in areas where metals in soils are accumulated, and metal levels in stems were 80-90% of those found in roots, while the concentrations detected in leaves were significantly lower than those in roots.
