In recent years, the input of antibiotics into soils has sharply increased. The environmental behavior of antibiotics is not well known and the precise environmental risk assessment is not practical. Long-term studies have shown the efficiency of the diagnostics and monitoring of soils with biochemical methods, particularly with the help of the indices of soil enzymatic activity. We studied the impact antibiotics (benzylpenicillin, tilosin and nystatin) at different concentrations (100, 500 mg/kg) on hydrolase (ph...

In essence, the paper presents the tracking of the behavior in time of hydro-technical constructions by establishing the horizontal displacements (dx and dy) compared to the base tranche and the previous tranche, and also the processing of these measurements and establishing conclusions and recommendations regarding the behavior of the objective taken into study. As studied objective was elected C?nde?ti dam, which is located in Buz?u county, at about 19 km upstream from town Buz?u. The dam is situated on the Buz?...
