Abstract
Regards to the importance of using safe vegetables, controlling the concentrations of heavy metals is necessary for
consumer's health. Therefore, this study was aimed to evaluate the potential risk of heavy metals on human health for
non-cancerous and cancerous diseases through consumption of agricultural products in Isfahan province. The samples
were included wheat, rice, carrots, onions, leafy vegetables and potatoes which were collected randomly from the
studied area. In order to assess the risk of non-cancerous diseases, Target Hazard Quotient (THQ) and Hazard Index
(HI) were calculated for a specific element as well as combinations of different elements. The results showed that the
THQ for arsenic was more than one in wheat and was less than one for other heavy metals if one product is consumed.
This indicates that the likely effects of arsenic for noncancerous diseases of wheat are not alone, rather they are for
other elements in various products. Risk indicators for men and women are 2.6 and 2.9 respectively, which indicates the
effects of noncancerous diseases resulting from consumption of products. Cancer risk due to arsenic in samples of
wheat consumption is higher than the Onion and potential cancer risk for this disease for this element is in the middle.
The parameters for the lead element in both cases is low.

Abstract
Soil pollution and accumulation of heavy metals in soils and crops are the most important bioenvironmental problems that threaten the life of plants, animals and humans. This study was conducted to explore contamination of heavy metals in soils of Hamadan province. A total of 286 composite surface soil samples (0-20 cm) were collected thoroughout the province. After preparation of the samples, the total contents of Zn, Pb, Cu, and Ni in soil samples were extracted using HNO3. Total contents of heavy metals were measured by ICP. Contamination factor results showed that most samples were moderately polluted and contamination factor for lead was highly polluted. Interpolated distribution map of contamination factors (CF) and pollution load index (PLI) of the heavy metals were prepared using GIS. The overlap of CF and PLI maps with geology and land use maps indicated that the concentrations of Ni, Pb, Zn, and Cu have been controlled by natural factors such as parent material, but agricultural activities according to excessive consumption of animal manure and chemical fertilizers can increase most of these elements in soil.

Abstract
Heavy metals are known to have deleterious effects on human health. The main route of human exposure to heavy metals is the daily intake of food. This study was designed to investigate the heavy metal concentrations (Cu, Zn, Mn, Fe, Cr, Ni and Cd) in soil and major food crops (wheat, potato and corn) and estimate the health risks of metals to humans via soil and the crops consumed in Hamedan Province, using the total non-cancer hazard quotient. Daily metal intakes were estimated for three receptor groups and then compared with health guideline values. The non-cancer risk estimations showed that chromium, manganese, cadmium, zinc, Iron, Nickel and copper have oral Hazard Quotient values less than a value of one. The Hazard Index values were greater than 1 for all age groups, suggesting that adults and children in the study area may experience a potential non-cancer risk due to diet of heavy metal via wheat, corn and potato consumption and soil ingestion. Consumption of plant foods particularly wheat was found to be the major route of human exposure to heavy metal. The soil ingestion route is also important.
