Soil and Land Suitability Analysis

In the northwestern part of Romania there is one of the most polluted cities in the country, Baia Mare. Non-ferrous ore exploitation, it’s processing in smelting and flotation plants are all sources of environmental pollution by sulfur oxides and heavy metals. Research has revealed that the content of heavy metals in the upper horizon of soils from small vegetable gardens of inhabitants exceed the maximum allowable limits up to: 3.6 (Cd), 7.95 (Cu), 46.3 (Pb) and 11.5 (Zn) times. Also, in the edible part of vegetables grown in gardens of peripheral areas denizens were determined heavy metals contents up to 2.94 mg•kg Cd, 71 mg•kg Cu,7 600 mg•kg Pb and 356 mg•kg Zn. The mobile heavy metals content of soil and horticultural plants recorded direct proportionality relationships, statistically assured, correlation coefficients having values between 0,413 and 0,829.
