Abstract
This paper presents a physico-chemical and ecological characterization of some ponds of anthropogenic origin, resulted from the drilling and extraction of lithological substrate. These artificial water bodies located in a Natura 2000 protected area are the result of some environmental pressures and replaced a potential meadow vegetation. The study aims to characterize the ponds in the perspective of their evaluation as support habitats for fauna and vegetation. For this, some typical physico-chemical parameters of water bodies, important to aquatic life, were analyzed: conductivity, pH, dissolved oxygen, oxygen saturation, turbidity, temperature, ammonium concentrations, nitrate, nitrites, free ammonia, total ammonia, free residual chlorine, total chlorine, phosphates, iron, copper, total alkalinity and water hardness. Also, the types of vegetation and natural habitats were identified and mapped. The analysis of the water quality in the studied area is very important for the conservation and improvement of the natural ecological system.
