Our study has found out that environmental sustainability of Bulgarian farms is at a good level. Finally, factors for improving environmental and overall sustainability of agricultural farms in the country are identified. Third, relations between environmental and socio-economic and integral sustainability of Bulgarian farms are specified. Sustainability assessment is based on a first large-scale survey on environmental aspects of sustainability of agricultural farms in the country carried out in 2016. After that a level of environmental sustainability of Bulgarian farms is evaluated in general and of farms different juridical type, size, production specialization, and ecological and administrative location. Initially the multiprinciple, multictiteria and mulriindicator framework for assessing environmental sustainability of farm in the country is outlined. This article applies a holistic framework for assessing environmental sustainability of Bulgarian farms. In Bulgaria there are no comprehensive studies on environmental sustainability of farms in general or different types.
Mechanical milling Pharmaceutical drugs Photocatalysis Thermal activation ZnO powders.The issue of assessment of diverse aspects of sustainability of agricultural farms is among the most topical in the last decades. The optimal temperature and time of mechanoactivation are experimentally established. The degradation rate of Acetaminophen and Chloramphenicol increases with time of mechanical activation up to 30 min and then decreases.
The ZnO powders annealed at 100 ☌ show highest photocatalytic efficiency and rate constant of dye degradation, which is due to the smaller size of nanocrystallites and their better developed surface. The changes in the studied material (phase composition, structure and particle size of the samples) and morphology have been investigated by means of X-ray diffraction and Scanning electron microscopy. The mechonoactivation is performed varying the atmosphere in air, or in suspension of ethanol and methanol. Commercial ZnO powders are activated thermally (annealed at different temperatures-100, 200, 300, 400 and 500 ☌ for 1 h) and mechanically (treated for 5, 15, 20, 30, 40 and 60 min). In this study we present photocatalytic purification of water from Acetaminophen and Chloramphenicol by ZnO upon UV-light illumination. They have been detected worldwide in environmental matrices, indicating their ineffective removal from water and wastewaters using conventional methods. Over the past few years, pharmaceutical drugs have been considered as emerging pollutants due to their continuous input and persistence in the aquatic ecosystem even at low concentrations.
