“…Consequently, human health is directly affected by the consumption of these plants, since there is no effective mechanism of excretion [44]. The study by Latif et al (2018) [72] shows how vegetables irrigated with wastewater differ in their potential to accumulate metals, and have Cr concentrations above the limit allowed by FAO in spinach, pumpkins, eggplants, etc. In the town of E Portes Gil, several plant species are cultivated for human consumption, such as pumpkins, parsley, coriander, among others, so that the risks to which the inhabitants of this agricultural town are exposed, are probably greater than those estimated.…”

The health risks of Emilio Portes Gil’s population, for the exposition to the Atoyac River pollution in the State of Puebla, was evaluated. The objective was to determine the concentration of nine heavy metals by ingesting water from wells and spri ngs. The chronic daily water intake (CDI), hazard quotient (HQ), hazard index (HI), and carcinogenic risk index (CRI) in adults, teenagers, and children were estimated. The results showed that the concentration of Fe, Al, Ni, and Pb in some of the samples exceeded the recommended standards for human consumption and was significantly higher in the dry season. The hazard index (HI), due to the collective intake of metals, was higher in children (> 50% compared to adults), due to the consumption of spring water in the dry season. Risk of noncancerous diseases was not detected in the long term, since the indices did not exceed the unit (reference value). The carcinogenic risk from oral exposure to Cr (CRIchildren = 3.2 × 10−4), was greater than the acceptable limit (1 × 10−6) in the water spring, and Cr and Pb were the main metals that contributed to the potential health risk of the inhabitants. The study showed the risks by the intake of polluted water from the sources of supply in the region, and that the risk is higher in the dry season (> 100% compared with rainy season).

In order to assess the effects of green synthesized nanoparticles (GNPs) of Zn and Fe oxides on plant growth traits, photosynthetic capacity and nutritional quality of red radish (cv. Champion), two open field experiments were organised based on RCBD with four replicates. Treatments included: chicken manure, foliar application of ZnO + FeO (GNPs at a rate of 60 and 50 ppm, respectively), chicken manure plus ZnO + FeO (GNPs). This study revealed that growth and yield of radish plants significantly increased by ZnO + FeO nanoparticles application. The maximum vegetative growth, leaf pigments and root quality (diameter and weight) were recorded in plants treated with ZnO + FeO (GNPs) alone or in combination with chicken manure. Furthermore, the combined application of chicken manure with ZnO and FeO significantly improved the concentration of anthocyanins, phenols, tannins, flavonoids, crude protein and carbohydrates contents in radish root than single treatment. Similar trends were noted in photosynthesis rate, water use efficiency and values of Zn and Fe contents. In addition, health risk index for Zn and Fe were less than 1, which indicated to red radish plants supplied with ZnO and FeO GNPs were free of risks on human health. It was concluded that combination between chicken manure and ZnO + FeO GNPs can be considered as appropriate strategy for improving yield and nutritional status of red radish.

“…However, low levels of lead (as compared to those recommenended by FAO/WHO) were reported in all the vegetables. So it was concluded that there is a great need for regular monitoring of heavy metals in the vegetables grown in wastewater-irrigated areas [37]. Wastewater irrigation profoundly affects the heavy metal (HM) fractions, their contamination levels and bioavailability in the soil.…”

A study was conducted to determine qualitative and quantitative lead contamination in soil along two major roadsides (Motorway M-2 and National Highway N-5) of Thokar Niaz Baaig (TNB) in Lahore, and adjoining areas of the Hudiara drain in Pakistan by employing the digestion method using HCl/HNO 3 at 1:4. The characterization of lead (Pb) was performed by atomic absorption spectroscopy. High deposition of lead was observed along the soil of linking roads of rather populated towns of Lahore, Pakistan, and the soil irrigated by the wastewater of Hudiara drain. The lead contents originated mainly from vehicular emissions, urban pollution and industrial effluents, and may lead to a rise of lead levels in the vegetation of associated areas. The present study also explores a comparison of heavy metal (Pb, Cu, Cd, Zn, Ni, Fe, Mn, Cr, Ti) concentrations in different areas of Pakistan and its adverse effects on plant growth. There is a need to strictly monitor the water quality in the Hudiara drain; its wastewater should be avoided for irrigation purposes. Some fungal strains can also be used to control the heavy metal concentration in such polluted water. However, some beneficial effects of Hudiara drain wastewater as a nutritional source for plants have also been suggested. It is important to establish the proper nutrition conditions in areas of contaminated soil.
