Among 9 crops, the field pumpkin and red beet were characterized by the highest zinc accumulation, especially in the leaves of 119.14, and 64.97 mg kg-1. [9] The study showed that the Zn concentration in edible algae contained highest concentration, up to 1,634 mg kg-1, extremely high. The source of contamination usually came from industry waste, metal plating and plumbing. The edible plants especially growing far from chemicals and hazardous heavy metals could be though to be less exposed to pollution, as well as the growing environment. Thus the pollutant levels among the water reservoirs did not identify the cause of impairment. To investigate the relation between the site of measurement and sources of contamination is quite important for surveillance and monitoring. The surveillance should be determined in all seasonings.
