Abstract


Most Romanian power plants were built in a period when environmental impact of their operation was undervalued, and constraints related to environmental protection were relatively few. Location of power plants and fly ash dumps was chosen most often by arbitrary criteria, and never after the impact that it may have on the environment. Building fly ash dumps have an effect of destruction of soils not only on the surface equivalent to those of dumps but also of the contiguous lands. Old fly ash dumps are a major risk because of the dispersion of pollutants in water and soil by percolation and soil leaching, and because of the unwanted invasion of weeds that are adaptable to arid conditions of the dumps and then invade surrounding areas jeopardizing the surrounding crops. In attempting to install vegetation an old fly ash dumps, the area were invaded by two species of weeds that quickly overgrown the experimental parcel and the surroundings. The present study followed the invasion degree of fly ash dumps with weeds and aspects regarding their development and breeding in the new formed ecosystem.
