Heavy metals are among the most environmentally toxic substances. Cadmium (Cd) and Lead (Pb) are extremely toxic heavy metals and their presence in the soil poses severe danger to the food security and consequently human health. Present study was carried out to investigate the concentration of Cd and Pb in soil, Orange and human blood. Soil and orange fruit samples were collected from same garden. Blood samples were taken from 6 volunteers at two stages before consumption and 4 hours after orange fruit consumption. Cadmium concentration in soil samples were found to be higher than the permissible limit of Cd set by the World Health Organization (WHO). It was noted that Pb concentration in soil was within safe limit of WHO. Orange fruit exceed the safe limit for concentration of both the metals. The cadmium concentration in blood sample before (2.7 ± 0.3ppm) and after eating orange fruit (2.75 ± 0.3ppm) were found different. The difference between cadmium concentration before and after consumption is 0.05ppm. The lead concentration in blood before consumption of orange fruit was (5.05 ± 1.15ppm) while after consumption was (5.88 ± 1.25ppm). The difference found between before and after treatment is 0.83ppm. Further investigation is suggested to find the effect of toxic metals like Cadmium and lead on human physiology and biochemistry.
