“…Health risk due to heavy metal contamination has been widely reported (Baker et al, 2000;Claire et al, 1991;Duruibe et al, 2007). Crops and vegetables grown in soils contaminated with heavy metals have greater accummulation of heavy metals than those grown in uncontaminated soil (Eriyamremu et al, 2005).…”

People in recent times have engaged in the habit of cultivating on abadoned dunpsites or soil collected from the existing ones because of their fertility. Lycopersicun esculentus is one of the vegetables that is mostly cultivated on such sites and also commonly consumed in Nigeria. Uptake of heavy metals by tomato (Lycopersicum esculentus) grown on soil collected from dumpsites located in Ekiti State, Nigeria was determined with a view to monitoring the pollutional status of the environment. Concentration of heavy metals were found in the range of ) and Zn (7.54-91.10) all in mg/kg. The sequence of accumulation is in order of leaf>stem>root>fruit and Translocation factor (TF) values greater than 1 revealed that heavy metals were translocated into the aerial part of the plant. However, the study serves as pathway for the investigation of these heavy metals which may eventually enter the food chain and subsequent ingestion by man.

“…The daily metal intake (DMI), dermal absorbed dose (DAD), and exposure concentration (EC) were estimated to assess the risks posed by the studied trace elements in soil and plants collected from the studied area via ingestion, dermal contact, and inhalation pathways according to the human health evaluation manual (Part A) and supplemental guidance for dermal and inhalation risk assessments (Part E and F) 3 . The equations were as follows:…”

“…Although some of the heavy metals such as Zn, Mn, Ni and Cu act as micronutrients at lower concentrations; they become toxic at higher concentrations. Health risk due to heavy metal contamination of soil has been widely reported [3][4][5]. Intake of vegetables is an important pathway of heavy metal toxicity to human being [6].…”

A B S T R A C TTo assess the leakage of sanitation service in urban areas on the contamination of water streams and soil besides, a risk assessment study was conducted through the intake of edible plants from polluted irrigated suburban area of El-Zomor area, Egypt. The results revealed that concentrations of trace elements were several folds higher in the studied site compared to the background level in the earth crust indicating that the soil of the studied area is contaminated with heavy metals. Therefore, contamination factor (CF) values of this area indicate that soils were considerably contaminated with Cd, moderately contaminated with Co, Cu, Pb and Mn, but showed signs of low contamination with other metals. Enrichment factor (EF) indicating that moderate enrichment of Cu and very significant enrichment for Cd were contributed to anthropogenic source. To assess the health risk, estimated exposure and risk index were calculated. For the non-carcinogenic risk, the studied elements were not found to cause any risks to the local population, since the hazard index (HI) for studied trace elements were lower than the safe level. The level of cancer risk associated with exposure to these elements falls within the range of safe limits (10 -4 -10 -6 ) so we consider the risk is unacceptable.
