Background: Accumulation of heavy metals and increasing their concentration and reaching them to the danger range can threaten human health by entering to food chain. Thus, continuous monitoring of pollutants consentration in agricultural products is important. So, the aim of this study was to investigate the heavy metals concentration and risk assessment resulting from them in agriculture product with two types of irrigation in farms of Dayyer city which is one of the counties in Boushehr province.

Material and Methods: Samples of agriculture product were harvested in three in three categories vegetables included: leafy (lettuce, spinach, cabbage), tuber (onion, potato), and fruit (tomato, green pepper) from farms of Dayyer city with two types of irrigation included River Water Irrigation (RWI( and Ground Water Irrigation (GWI). Totally 320 samples were analyzed by using (ICP-OES -Spectrum Arcos) after acidic digestion steps and extraction of heavy metals from samples. Then, the obtained results were analyzed by diffrent equations and statistic softwares.

Results: results showed that the concentrations of metals were 68.75 (47.71), 277.62 (196.12), 32.68 (18.31), 42.19 (17.09), 1.76 (0.87) and 12.04 (5.83) mg kg-1 for Zn, Mn, Cu, Cr, Cd and Pb in RWI (and GWI), respectively in irrigated farms with river water (farms irrigated by ground water). The concentration of heavy metals was significantly higher in the soil of farms which irrigated with river water than those which irrigated with ground water (P<0.05). Also, results showed that in farms which irrigated by ground water, the highest Target hazard quotient (THQ) have been reported in spinach with mentioned values; Zn (0.1150), Cd (1.2846), Cu (0.2030) and Pb (1.9141).

Conclusion: The findings of this study showed that the concentration of heavy metals in soil and agricultural products which irrigated with contaminated water with urban and industrial sewage was higher than soil and agricultural productswhich irrigated with ground water. Also results of this study showed that the hazard for consumers health in agricultural products that were irrigated with water contaminated by industrial and urban sewage was higher than which irrigated with ground water. The researchers of this study suggest that we seriously should be avoided from entering the urban and industrial sewage to water which irrigate the agricultural products.
