“…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. Moreover, the information collected by Arain et al (2009) …”

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.

“…Perishable vegetables are often grown around urban areas, which are more prone to heavy metal contamination due to variety of urban and industrial activities. Continuous use of waste water for irrigation leads to the accumulation of heavy metals in vegetables (Amin et al 2013). It is mentioned that plants can absorb metals from different sources such as: factories activity, fuels, agriculture activities, waste waters and environmental air pollution (Abbas et al 2010).…”

Abstract:In this study, heavy metals pollutions in waters, soils and vegetables were investigated from farms, near oil refi nery in south of Tehran city, Iran (Shahre Ray). The most important heavy metals in Iranian oil are vanadium, cobalt, nickel, arsenic and mercury (V, Co, Ni, As, Hg). In this region, the concentration of heavy metals in soils, well waters and leafy edible vegetables were evaluated in ten different points of farms. Geographic information systems (GIS) were used to estimate the levels of heavy metals concentration at unmeasured locations. After sample preparation, concentrations of heavy metals in vegetables, soils and waters were determined by atomic absorption spectrometry (AAS). Five different leafy edible vegetables from farms, i.e., Persian leek, dill, parsley, spinach and radish were sampled in spring, summer and autumn 2012. In vegetables and well water samples, the concentrations of V, Ni and Co were above the permissible limit of heavy metals as compared to WHO guidelines and the concentrations of these metals in agricultural soils were found to be lower in accordance to soil references. The industrial waste waters had high concentration of heavy metals in this area. In consequence, the results of this study indicate that industrial waste water can cause pollution in well waters and edible vegetables. So, this region is not suitable for cultivation and growing vegetables.Unauthenticated Download Date | 5/13/18 2:45 AM

“…La alfalfa utilizada se colectó por triplicado al inicio de la floración, de los mismos sitios de donde se extrajo el suelo, a una profundidad de 0 a 30 cm (18) y se trasportaron en bolsas oscuras al laboratorio, donde se les lavó con agua desionizada hasta eliminar todo tipo de residuos de suelo, al mismo tiempo que fueron pesadas en su totalidad y por partes, siendo separadas en parte comestible (hoja-tallo) y raíz (19,20) , congelándolas para luego ser liofilizadas. Posterior a ello se molieron, tamizaron y almacenaron en bolsas de nylon hasta su digestión.…”
