The paper presents the results of bioremediation experiment conducted in order to determine the effectiveness of this method for the decontamination of a soil historically contaminated with heavy metals and artificially controlled with two of the most aggressive group of organic pollutants: hydrocarbons from crude petroleum and polychlorinated biphenyls from transformer oil. The experiment followed how a heavy metals polluted soil respond to innoculation

It is presented the possibility to reduce contents of heavy metals (cadmium, zinc) in a sludge proceeded from the wastewater treatment plant of Iaşi Municipality. The sludge was deposited, for over 10 years, in a mud pond with a surface about 15 ha, placed on a calcareous and salinised alluvial soil. For this purpose, it is proposed using the spontaneous flora, which has been settled in a period of four years after closure of the deposit. The flora

The soil cover of the Fãgãraş Depression consists of different types and sub-types belonging to the following classes: Protisols, Umbrisols, Cambisols, Luvisols, and Hydrisols. These soils are generally acid, with low humus and total nitrogen contents and low up to average mobile phosphorus and potassium contents. They have a predominantly loamy texture. The heavy metals contents are normal. The total selenium content oscillates between 12 and

Since the introduction of insect-resistant crops in 1996, cultivation of this group of genetically modified crops has grown substantially. There are many Bt corn events in field trials, but only one is commercialized on the Romanian market. The levels of the protein in plant tissue would be valuable in determining the protein concentration to which nontarget organisms may be exposed. The soil fate of the Bt protein is a key parameter governing exposure
