The Risk Assessment of Fruit Copper Uptake from Soil

The heavy metals uptake from soil into the edible parts of plants represents an important problem, especially if their toxicity, non-biodegradability and the ability to be accumulated as the most dangerous characteristics that directly affect the consumer's health are concerned. The content of heavy metals in soil depends on the characteristic and the type of soil, heavy metals immission, the intake with fertilizers, pesticides, adsorption mechanism and/or fixation, type of fruit sort etc. The aim of the paper is to present the differences in the presence of copper in the soil with different pH values, and the content of organic substances and their influence on the copper content in the fresh plum fruits. The results of the conducted studies show that the accumulation of copper from soil into fruit depends not only on the type of soil content but also on the fruit sort. It can also be generally said that the increase, or the decrease in soil acidity contributes the incr ease of copper accumulation from soil into fruits in particular sorts, but its concentration in fresh plum is very low.
