Manganese content in the soil and foliage of some tree species in NP "Fruška Gora"

This paper analyses manganese content in the air, in the soil and in the vegetative parts of seven tree species at seven localities. Soil and plants contaminated by heavy metals can cause environmental risk and cause health problems. Heavy metals are substances which signalize environmental pollution. Within the study of other heavy metals (lead, nickel, zinc and iron), manganese content was analyzed in some tree species depending on the concentrations of manganese in the soil and air in the National Park "Fruška Gora", along the road M-21
