“…Heavy metals can build up in soil environments and can transfer across the food chains, causing negative health impacts on human and animals. A number of studies have shown heavy metals as imperative environmental contaminants (Abbas et al 2010;Sobukola, Adeniran, Odedairo & Kajihausa, 2010;Kaur & Goyal, 2011;Asdeo & Loonker, 2011;Hu et al 2012;Kananke, Wansapala & Gunaratne, 2014, 2015Haneef &Akintug, 2016 andNgo &Tran, 2017). Through the atmospheric deposition or road runoff, metals are absorbed into the plant tissues of green leafy vegetables (GLV) which are cultivated and marketed along roadsides.…”

“…Leafy vegetables have high potential to accumulate heavy metals in their tissues (Otitoju et al, 2012;Surukite et al, 2013;Gupta, Nayek, Saha & Satpati, 2013;Chang et al, 2014;Kananke et al, 2014Kananke et al, , 2015Kananke et al, , 2016. Usually, the plants can uptake high quantities of heavy metals when they are grown in highly contaminated soils.…”

Green Leafy Vegetables (GLV) are a key component of the Sri Lankan diet. However, GLV are identified as good heavy metal accumulators, which in turns causes potential health risks for consumers through food chain contaminations. The present study aimed to investigate the bioaccumulation, translocation and distribution patterns of cadmium (Cd) and lead (Pb) in five key Sri Lankan GLV ["Kankun" (Ipomoea aquatica), "Mukunuwenna (Alternanthera sessilis), "Thampala" (Amaranthus viridis), "Nivithi" (Basella alba) and "Kohila" (Lasia spinosa)] grown in Colombo District, Sri Lanka. The levels of Cd and Pb in different plant parts (roots, stems and leaves) and the soil underneath were determined using the inductively coupled plasma optical emission spectroscopy (ICP-OES) and the bioaccumulation and translocation factors of heavy metals from soil to different plants parts (roots, stems, leaves), were calculated to identify the hyper accumulative species.Irrespective of the species and the location, GLV showed the distribution pattern for Cd and Pb as: roots>stems>leaves. In all the analyzed GLV, roots have accumulated significantly higher concentrations (at P<0.05) of Cd and Pb compared with stems and leaves. Among the two heavy metals, Cd bioavailability was higher compared with Pb. Amaranthus viridis had the lowest capacity for metal enrichment. In contrast, Lasia spinosa showed the highest bioaccumulation factors for both elements and the accumulation factor obtained for Cd (1.04) was >1. Thus, Lasia spinosa has the potential to use in phytoextraction purposes in future, though it is not safe to consume as a day to day food item.

“…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).…”

Evaluation of the environmental geochemistry needs studying element content in different environmental profiles, for that reason the zinc content has been studied in the soil-plant to fill gaps in Kirkuk City. Ten soil samples (L1–L10) are collected from agricultural fields (0–20 cm depth), with twelve leafy vegetable samples for four types, and each type has three samples: celery (N1, N2, N3), basil (N4, N5, N6), cress (N7, N8, N9), and arugula (N10, N11, N12) from the fields (L2, L7, L8) which the soil sample were chosen. Samples were analyzed using ICP-MS technique. The results show the average concentration value of Zn in soil samples is 70.91 mg/kg the highest concentration is recorded in sample L7 (169.2 mg/kg), whereas in the plant samples the highest average of Zn was found in cress 67.73> basil 52.53> arugula 38.9> celery 29.3 in mg/kg, respectively. Transfer factor value showed that the highest value in Cress 0.729> TF Basil 0.612> TF Arugula 0.511> TF Celery 0.395, respectively. Igeo result values show that all soil sampling sites are unpolluted with Zn, except L7 is unpolluted to moderate with Igeo value (0.8). The contamination factor values in L7, L8, L9, L10 samples (2.603, 1.284, 1.086 and 1.129) refers to a moderate contamination level with Zn. Target hazard quotient values for children >1 in samples N4, N5, N7, N8, N9, N10, and target hazard quotient values for adult >1 in samples N5, N8, N9, that indicate they are exposed to different health effects. The increase in the concentration of the Zn in soils is due to irrigated field crops with wastewater, and through it, the plant absorbs it by root depending on the type of plant, the location of the sample, and the soil properties.

“…Alam et al, (2003a), also highlighted that millions of people have been affected in Bangladesh due to the use of As-contaminated water from tube wells where contaminated water is being used for drinking, cooking, washing, and irrigation of food crops. Eventually, heavy metals contamination cause health effects through food chain (Wickramaratne et al, 2016;Kananke et al, 2015b;Alkhader, 2015) On the other hands, contamination of relatively higher-level heavy metals (e.g. -Cd, Cu, Zn, Pb, Ni) have been reported in various food crops such as Abelmoschus esculentus L, Solanum melongena L. Brassica campestris L. Beta vulgari L, Pimpinella anisum L, Cucumis sativus L, Pysum sativum L, Coriandrum Sativum L, Spinacia oleracea L, Lycopersicon esculentum L, Brassica oleracea L and many more.…”

Heavy metal contamination in food crops and ground water lead toxic effects on living organisms through the interference of the metabolic pathways. In this paper, the prevailing scientific data, with regard to the accumulation of heavy metals in groundwater and food crops in Sri Lanka, were reviewed. Evidence revealed that the groundwater bodies in Sri Lanka are in safer level to be used for day-to-day activities with a few exceptions and however, the heavy metal accumulation in some food crops are beyond the permissible level. Chronic Kidney Disease of unknown aetiology is one of the emerging issues at present in dry zones, particularly in the North Central Province in Sri Lanka and its suspected due to the extensive use of agrochemicals which is believed to be contaminated with the heavy metals.
