“…The results indicated that sewage wastewater use in irrigating these vegetables caused a significant increase in Pbcontent in their edible portions. These results are in an agreement with those of Rattan et al (2005) and Ismail et al(2014). Also, Eissa.…”

“…Thus, levels of Ni in the edible parts of these plants were higher than its permissible limit level. These results are in the same line with those of Rattan et al (2005) and Ismail et al (2014). The prolonged application of treated and untreated wastewatersresults in significant buildup of heavy metals in the soils (Khan et al, 2008;Ullah et al, 2011;Gosh et al, 2012) and grown vegetables and cereals which are subsequently transfer to the food chain causing potential health risk to consumers (Sharma et al, 2006;Singh et al, 2010;Gupta et al, 2011).…”

“…The increasing of population and human activities enlarged the volume of sewage wastewaters (SW) (Qadir et al, 2007;Ismail et al, 2014).

Nowadays, using sewage wastewater in the irrigated agriculture causes hazardous environment impacts. Assessment of these negative effects is vital issue to prevent heavy metals to be introduced in the food chain. Field and laboratory studies were conducted at Ellwan, Mangabad and El-Madabegh villages, Assiut Governorate, in order to evaluate heavy metals concentrations in the edible parts of carrot, turnip and onion plantswhich were irrigated with sewage water (SW). The obtained results indicated that, the soils of the studied villages were contaminated by heavy metals. The concentrations of Zn, Cu, Pb, Cd and Ni concentrations in the edible portion of thesevegetables plants ranged between 45-70, 13-19, 3.8-6.2, 2.85-3.85 and 2-6 mgkg -1 , respectively. The obtained results showed that the concentrations of Pb, Cd and Ni in the edible plants were higher than the permissible limit levels but those of Zn and Cu were within the safe limit levels. It is worthy to mention that the irrigated edible vegetable crops especially onion, turnip and carrot with SW should be avoided. This study highlights the potential hazard for human health due to uptake of high concentrations of heavy metals especially Ni, Cd and Pb by the studied vegetable crops.

“…Nickel (Ni) is a trace mineral element required for the normal growth and maintenance of human body but the excessive doses of Ni may result in carcinogenicity, neurotoxicity, reproductive disorders and may also result in oxidative stress (Ismail et al, 2014;. Significant differences were observed in the Ni concentration of oil samples collected from different zones of Multan city.…”

Cooking oil has become a part and parcel of modern food system and therefore its safety is of prime significance for health agencies around the globe to ensure good health among the community. Current study was designed to investigate the physicochemical properties including free fatty acids, peroxide value and conjugated dienes; minerals (nickel & cobalt) and heavy metals (lead and cadmium) in oil samples collected from different areas of Multan city of Pakistan. The findings of this study revealed that free fatty acid percentages, conjugated dienes, cobalt and nickel concentrations were in normal ranges while the peroxide values, lead and cadmium concentrations were recorded above the norms. Strict regulatory measures need to be adopted to ensure good quality oil supply and to protect the people from health implications of physicochemical and metallic hazards prevailing in fried oils and fried foods.

Beans and vegetables are consumed with cereals in India on daily basis. The aim of the study was to assess carcinogenic and non‐carcinogenic risk of heavy metals in cooked beans and cooked vegetables consumed by adults (18–59 years) and elderly (≥60 years) subjects from two districts (Ludhiana and Bathinda) of Punjab. A total of 150 households were selected from 30 different locations covering both rural and urban areas. The mean daily consumption of beans and vegetables in Ludhiana was recorded as 35.09 and 215.93 g, respectively. The corresponding figures in Bathinda were observed as 26.85 and 230.54 g. The average amounts of arsenic, cadmium, lead, and mercury were 1.44 × 10−5, 8.21 × 10−5, 1.30 × 10−3, and 2.61 × 10−7 mg/kg for cooked vegetables in urban households of Ludhiana district, respectively. The corresponding values for rural households were 1.53 × 10−5, 5.58 × 10−5, and 2.98 × 10−4 mg/kg while mercury was not detected. The mean chronic daily intake (CDI) of arsenic from cooked beans was significantly (p ≤ .001) higher in urban adult males of Ludhiana (7.74 × 10−9 mg/kg/day) and Bathinda (5.31 × 10−9 mg/kg/day) compared to their rural counterparts. Similar trend was observed in CDI of heavy metals from vegetables. The mean CDI of cadmium from cooked vegetables in urban adult females of Ludhiana (3.76 × 10−7 mg/kg/day) was significantly (p ≤ .001) higher than their rural counterparts and both urban and rural adult females of Bathinda. The study concluded that the subjects of both districts were found safe from non‐carcinogenic and carcinogenic risk associated with heavy metals present in cooked beans and vegetables, except for urban subjects and rural adult subjects of Ludhiana district who had cancer risk due to cadmium present in cooked vegetable samples.
