Analysis of the models for life cycle assessment of the building and building products
Environmental Engineering and Management Journal › Vol. 6 › Nr. 1 The environment is the relations in life and all settings life is consist of. A building is an artificial environment designed and built to meet the users' needs. These needs are fulfilled with the properties of building products that form the building. Building and building products are directly or indirectly in interaction with the environment during their life cycle process.There are some models like 'LEED', 'Athena', 'BEES', 'BRE', 'Analytica', 'Pre', 'GaBi', 'TEAM', 'GB Tool', 'Woolley','Cu...

Environmental Engineering and Management Journal › Vol. 16 › Nr. 5 The present work illustrates the results of a long-term field experiment with sewage sludge used on agricultural land in order to assess the influence of sewage sludge on wheat crop productivity. The experimental research was conducted for three years as following: the evaluation of the agricultural use of sewage sludge in the year of application and its residual effect in grain and in soil for the next two years. The sewage sludge considered in the framework of the study was from Sfantu Gheorgh... Autori: Diana Mariana Cocarta ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27303
QUANTIFICATION OF EFFECTS PRODUCED BY THE EXTRACTION OF MINERAL AGGREGATES TOWARDS WATER BODIES
Environmental Engineering and Management Journal › Vol. 16 › Nr. 4 This paper presents the research performed in view of emphasizing the effects of mineral aggregates extraction on the geomorphological and hydraulic features of Moldova body of water. The effect on the geomorphological features was assessed by overlapping the cross profiles (22 profiles) and long profiles (2 profiles) from the entire area studied. These profiles were obtained by topographical measurements on the starting date (July 2013) and on the research end date, respectively (March 2015). T...

COMPARATIVE STUDY OF URBAN AND RURAL ATMOSPHERIC AEROSOLS IN AND NEAR BUCHAREST, ROMANIA
Environmental Engineering and Management Journal › Vol. 16 › Nr. 10 The temporal variation of the pollutant (PM10) levels over urban and rural sites in and near Bucharest was investigated from March 2014 until September 2015. The comparison between the PM10 mass concentration values at urban site and those from referential urban station of Environmental Protection Agency of Bucharest allowed us to detect certain pollution events. Considering this purpose the optical parameters characterizing the loading of the atmosphere (Aerosol Optical Depth-AOD) and the type ...
