“…From the above data, it is apparent that the consumption of the examined vegetables do not expose local inhabitants to a potential health risk from dietary Cd, Co, Cr, Cu, Ni, Pb and Zn. The results obtained in the present study did not concur with THQ values recorded by Zheng et al (2007), Zhuang et al (2009) and Hu et al (2014). Among the metals THQ values, the greatest values were obtained for Pb for the consumption of wastewater-irrigated vegetables at 5 sub-city administrative areas and were in the order: Chirkos (0.298) > Nefas Silk Lafto (0.244) > Bole (0.243) > Akaki Kaliti (0.197) > Kolfe Keraniyo (0.194).…”

“…Comparing sub-city administrative areas, the TTHQs of the metals decrease in the order of Chirkos > Nefas Silk Lafto > Akaki Kaliti > Bole > Kolfe Keraniyo. The present result indicate that Pb and Cd were the major component contributing to the TTHQs, in agreement with separate assessments for areas near Huludao Zinc plant in Huludao, China (Zheng et al 2007) and in the vicinity of Dabaoshan mine in Shaoguan city, China (Zhuang et al 2009). In the studied sites, the consumption of all analyzed vegetables resulted in TTHQ values of less than 1, compared to the high TTHQ values obtained from emerging economies (Abbasi et al 2013;Qureshi et al 2016).…”

“…The THQ has been recognized as a useful parameter for the evaluation of risk associated with the consumption of contaminated (metals) food crops (Zheng et al 2007;Zhuang et al 2009). Target Hazard Quotient value of less than 1 indicates a relative absence of health risk associated with the consumption of metal contaminated food crops (USEPA 2007).…”

Background: Wastewater irrigation for vegetable production is a highly prevalent practice in Addis Ababa and a number of articles have been published on wastewater-irrigated soils and vegetables contaminated with heavy metals. However, to the best of our knowledge, an insight into assessment of human health risks associated with the consumption of vegetable crops grown on wastewater-irrigated soils is non-existent in the city. Long-term effect of wastewater irrigation on the build-up of heavy metals in soils and selected vegetable crops in Addis Ababa urban vegetable farming sites (10) was evaluated. By calculating estimated daily intakes (EDIs) and target hazard quotients (THQs) of metals, health risk associated with the consumption of the analyzed vegetables was also evaluated. Results: The heavy metal concentrations in irrigation water and soils did not exceed the recommended maximum limits (RMLs). Moreover, Cd, Co, Cr, Cu, Ni and Zn concentrations in all analyzed vegetables were lower than the RML standards. In contrast, Pb concentrations were 1.4-3.9 times higher. Results of two way ANOVA test showed that variation in metals concentrations were significant (p < 0.001) across farming site, vegetable type and site x vegetable interaction. The EDI and THQ values showed that there would be no potential health risk to local inhabitants due to intake of individual metal if one or more of the analyzed vegetables are consumed. Furthermore, total target hazard quotients (TTHQs) for the combined metals due to all analyzed vegetables were lower than 1, suggesting no potential health risk even to highly exposed local inhabitants. Conclusions: There is a great respite that toxic metals like Pb and Cd have not posed potential health risk even after long term (more than 50 years) use of this water for irrigation. However, intermittent monitoring of the metals from irrigation water, in soil and crops may be required to follow/prevent their build-up in the food chain.

“…Based on the questionnaire survey, it was found that children at 10 years had less food (staple food and vegetables) for one day, compared to other groups with different ages (P b 0.05). Thus, it might pose less risk of lead exposure to the 9-aged children, since food exposure via ingestion pathway was the largest contributor (accounted for 66% to 80%) to the children's average daily dose of lead exposure (Dong and Hu, 2011;Qu et al, 2012;Zheng et al, 2007). Moreover, seldom children aged 10 years showed a behavior of touching activity.…”

Lead exposure in the environment is a major hazard affecting human health, particularly for children. The blood lead levels in the local children living around the largest coking area in China were measured, and the source of blood lead and the main pathways of lead exposure were investigated based on lead isotopic ratios ( 207 Pb/ 206 Pb and 208 Pb/ 206 Pb) in blood and in a variety of media, including food, airborne particulate matter, soil, dust and drinking water. The children's blood lead level was 5.25 (1.59 to 34.36 as range) μg dL −1 , lower than the threshold in the current criteria of China defined by the US Centers for Disease Control (10 μg dL −1 ). The isotopic ratios in the blood were 2.111 ± 0.018 for 208 Pb/ 206 Pb and 0.864 ± 0.005 for 207 Pb/ 206 Pb, similar to those of vegetables, wheat, drinking water, airborne particulate matter, but different from those of vehicle emission and soil/dust, suggesting that the formers were the main pathway of lead exposure among the children. The exposure pathway analysis based on the isotopic ratios and the human health risk assessment showed that dietary intake of food and drinking water contributed 93.67% of total exposed lead. The study further indicated that the coal used in the coking plant is the dominant pollution source of lead in children's blood.

“…In another study Al Jassir et al [35] studied 6 washed and unwashed green leafy vegetables from Saudi Arabia and observed the concentration of Pb in the coriander (0.171 mg · kg -1 ) and purslane (0.226 mg · kg -1 ). Several pathological conditions are associated with Pb intoxication in children and adults such as nervous and immune systems disorder, anemia and reduced hemoglobin synthesis, cardiovascular diseases and bone metabolism, and also renal and reproductive dysfunction [36,37]. Nickel was found in the range of 0.98 to 2.93 mg · kg -1 and 0.08 to 2.61 mg · kg -1 in wastewater and tube well irrigated vegetables of the studied area respectively.…”

Abstract:Vegetables are important source of nutrients for human body. Wastewater irrigation may lead to contamination of these vegetables and cause possible health risk. In the present study impact of waste water irrigation on metals uptake (Fe, Mn, Ni, Co, Zn, Cd, Cr and Pb) by five commonly consumed vegetables (radish, cabbage, lettuce, cauliflower and spinach) grown in the suburbs of Peshawar were investigated using AAS (Atomic Absorption spectrophotometer). The uptake and accumulation of metals for vegetables irrigated with wastewater were significantly (p < 0.05) higher than tube well irrigated vegetables and permissible limits of WHO/FAO. Among the edible parts of vegetables maximum accumulation of Mn, Pb and Cd occurred in radish followed by Ni and Fe in spinach while Cr and Zn were high in cauliflower and cabbage. The estimated daily intake of metals (DIM) revealed that at present the consumption of studied vegetables were under the tolerable limits of (US-EPA, IRIS), however intake of metals in waste water irrigated vegetables were significantly high and can cause health hazards in the long run.
