Health Risk Assessment of Heavy Metals for Population via Consumption of Vegetables Collected from Khassa River, Kirkuk City, Northern Iraq

Abstract

Article InfoThe present study was carried out to investigate heavy metal accumulation inthirtythree soil samples from different depths and six vegetable samples and to assess the human health risks of vegetable consumption. Four vegetable types (cress, leek, chard and celery) were irrigated with wastewater cultivated on farmland contaminated with heavy metals (Cu, Pb, Zn, and As) from Khassa river of Kirkukcity. The order of heavy metal concentration was found in Zn > Cu>Pb>As in vegetable samples and Zn > Cu>Pb>As was observed in soil samples. The health risk assessment methods include target hazard quotient (THQ) and hazard quotient (HQ) were used to assess the human health risks posed by heavy metals through vegetable consumption.

Heavy Metal Levels in Some Popular Vegetables from Some Selected Markets in Saudi Arabia

“…Nowadays, there is a great demand for food safety hence, the attention of many researchers to estimate the risks associated with consumption of many contaminated foodstuffs; heavy metals, pesticides and/or toxins in vegetables has increased (D'Mello, 2003;Latif et al, 2009 andIsmail &Rashid, 2017). Globally, many people consume street foods every day as a part of their diet.…”

Health Risk of Zinc Pollutant in Agricultural Soil in Some Leaves of Selected Leafy Vegetables in Kirkuk, North Iraq

“…According to the results, the highest average of Zn was in Cress 67.73> Basil 52.53> Arugula 38.9 > Celery 29.3 mg/kg (Table 3) and (Fig. 2), this increasing in Zn concentration is attributed to irrigation fields with wastewater (Ismail and Rashid, 2017), where the concentration of Zn in same or different type of vegetables are varied from one sampling location to another is dependent on the Zn concentration in sampling soil location (Mohamed et al, 2003), and ability of vegetable to absorb the zinc through their roots and transfer them to different parts of plant from soil (Kananke et al, 2015).…”

Trace Metals in Vegetables and Cereals- A Case Study of Indian Market-2016

“…A number of studies reveal that trace metals are an important fast growing contaminants in the vegetables and cereals (16)(17)(18)(19). Trace metal contamination of vegetables and cereals may be due to contaminated water irrigation, pesticides exposures as well as industries and vehicles emissions during their production, transport and marketing (14,(20)(21)(22)(23). The contamination of vegetables and cereals with trace metals due to soil and atmospheric contamination poses a threat to its quality and safety (3,24,25).…”
