When infrastructural routes pass through sites with a long-term natural balance, landslide processes may be instigated. The reason is the human intervention. The scale of this intervention is usually sufficient to break the balance border between the admissible human intervention and nature. Crossing this frontier is followed by increased expenditures and termination of construction activities. The subject of this paper covers not only the measures for the ecological balance to be efficiently restored. Attention i...

Metals occur in different forms : as ions dissolved in water, as vapours, or as salts or minerals in rock, sand and soil. They can also be bound in organic or inorganic molecules, or attached to particles in the air. Both natural anthropogenic processes and sources emit metals into air and water. The effects of metals in the environment depend to a large extent on whether they occur in forms that can be taken up by plants or animals. Uptake of metals in an animal involves metal ions crossing a cell membrane. The a...

Building of double bridges with doubling of railways in Bulgaria may generate conflicts at the points where they cross rivers. The conflict is arising usually by the approach of investors and designers to subordinate the river to the functions of the facility, without enough studies and preventive measures. The lack of solution of the conflict leads to more expenditures for correction, strengthening and maintaining of the river bed. The aim of the paper is to propose recommendations how bridges shall not create wa...
