“…In the study area, soil contamination with HMs is mainly due to the wastewater irrigation and application of sludge to the farmlands. HM concentrations in plants were inconsistent with the results in literature for both leafy and non-leafy locally grown vegetables [28]. Concentrations of Cd, Cr and Pb were higher than those in lettuce plants grown on wastewater-irrigated-farmlands in Beijing [13].…”

“…This finding also suggests that the consumption of such polluted vegetables grown in wastewater-irrigated soils could pose a threat to the health of the consumers. According to Wang et al [28], the consumption of vegetables and fish contaminated with the HMs such as Cd, Cr, Cu, Hg, Pb, and Zn is the most likely route for human exposure in Tianjin, China. Furthermore, they investigated that the Cd and Hg are the major contributors counting for 45% and 51% to the target hazard quotients.…”

Accumulation of polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs) by crop plants from contaminated soils may pose health risks. A greenhouse pot experiment using lettuce (Lactuca satuva L.) as a representative vegetable was conducted to assess the concentrations of PAHs and HMs in vegetables grown in wastewater-contaminated soils. The concentrations of total PAHs were ranged from 1.5 to 3.4 mg kg −1 in the contaminated soils, while 1.2 mg kg −1 in the reference soil. Linear regression analyses showed that the relationships between soil and shoot PAH concentrations were stronger for LMW-PAHs (R 2 between 0.51 and 0.92) than for HMW-PAHs (R 2 0.02 and 0.60), suggesting that translocation for LMW-PAHs is faster than HMW-PAHs. Furthermore, the data imply that root uptake was the main pathway for HMW-PAHs accumulation. The plant shoots were also highly contaminated with HMs, particularly Cd (0.4-0.9 mg kg −1 ), Cr (3.4-4.1 mg kg −1 ), Ni (11.7-15.1 mg kg −1 ) and Pb (2.3-5.3 mg kg −1 ), and exceed the guidance limits set by State Environmental Protection Administration (SEPA), China and the World Health Organization (WHO). This study highlights the potential health risks associated with cultivation and consumption of leafy vegetables on wastewater-contaminated soils.

“…Reference values for the food consumption rate of vegetables and fruits were taken from literature as 0.3 kg/ person/day for vegetables and 0.4 kg/person/day of fruits, respectively, while 60 kg was considered as an average adult weight (Wang et al 2005;WHO 2003). Arain et al (2009), Amin et al (2013) and Hossain et al (2013) calculated the HRI value for the risk estimation of different toxic metals and pesticides via food consumption and they used the general consumption rates (regardless seasonal and generic wise consumption) due to data scarcity.…”

The main objective of the review is to document, assess and analyze the results of the previously reported data on levels of different pesticides in selected fruits and vegetables from Pakistan. The findings of the previous studies clearly indicated that more than 50 % of the samples were contaminated with organophosphate, pyrethroids and organochlorine pesticides. Many studies reported that among fresh fruits and vegetables tomato, apple, melon, mango, grapes, and plum crossed the FAO/WHO permissible limits for these contaminants residual levels. The comparison of other regions showed that observed levels were found above maximum residue limits (MRLs) in 50 % of the samples but were in agreement with the studies from neighboring countries like China and Bangladesh. Higher hazard risk index (HRI) values were calculated for dieldrin, methamidophos, o,p′-DDT, diazinon and p,p′-DDT in apple, mango, banana, melon, potato and onion. The review also highlights that data on pesticide residues in foodstuff is scarce which should be overcome by further extending studies from different areas of Pakistan. In order to ascertain the provision of food suitable for human consumption, it is imperative to monitor pesticides in food commodities by the country's authorities and enforce guidelines based on permissible limits.

“…In contrast with agricultural soils, urban soils are characterized by the spatial heterogeneity of contamination (Alloway 2012;Meuser 2010), which complicates remediation strategies. Urban soil contamination by toxic trace metals is detrimental for soil quality but is also harmful for human health resulting from accidental soil ingestion and consumption of crops grown on these soils, generally more exposed to trace metals than when grown in rural areas (Finster et al 2004;Hough et al 2004;Säumel et al 2012;Wang et al 2005). Conventional soil remediation practices such as excavation are often considered…”

Urban soil contamination with trace metals is a major obstacle to the development of urban agriculture as crops grown in urban gardens are prone to accumulate trace metals up to toxic levels for human consumption. Phytoextraction is considered as a potentially cost-effective alternative to conventional methods such as excavation. Field trials of phytoextraction with Noccaea caerulescens were conducted on urban soils contaminated with Cd, Cu, Pb, and Zn (respectively around 2, 150-200, 400-500, and 400-700 μg g −1 of dry soil). Metallicolous (Ganges population) and non-metallicolous (NMET) populations were compared for biomass production and trace metal uptake. Moreover, we tested the effect of compost and fertilizer addition. Maximal biomass of 5 t ha −1 was obtained with NMET populations on some plots. Compared to Ganges-the high Cd-accumulating ecotype from South of France often used in phytoextraction trials-NMET populations have an advantage for biomass production and for Zn accumulation, with an average Zn uptake of 2.5 times higher. The addition of compost seems detrimental due to metal immobilization in the soil with little or no effect on plant growth.In addition to differences between populations, variations of growth and metal accumulation were mostly explained by soil Cd and Zn concentrations and texture. Our field trials confirm the potential of using N. caerulescens for both Cd and Zn remediation of moderately contaminated soils-with uptake values of up to 200 g Cd ha −1 and 47 kg Zn ha −1 -and show the interest of selecting the adequate population according to the targeted metal.
