Environmental Engineering and Management Journal › Vol. 17 › Nr. 12 Heavy metals are inorganic persistent pollutants with adverse health and environmental effects. In our study, self-synthesized iron oxide magnetic nanoparticles were encapsulated in the Phanerochaete chrysosporium (P. chrysosporium) hyphae. The prepared biosorbents possessed high efficiency for Pb(II) biosorption from single and binary metal systems. The maximum biosorption capacity was found to be 50.05 mg g–1 at pH 5.0. Environmental scanning electron microscope accompanied with energy d... Autori: Danlian Huang ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27864

small iron units preparing 90- 95 % iron furniture under sheds. Focused group discussions (FGD) were conducted among workers
of iron furniture manufacturing units (IFMU) employing a cross sectional, descriptive, analytic and time limited study. Personal
interviews methodology was adopted to assess workers for their exposure to occupational risks, protective eq... Autori: Saima Aslam Bharwana ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27925
ANALYSIS OF PROTECTION SYSTEMS FOR REDUCING THE EFFECTS OF SHOCK WAVES PRODUCED BY EXPLOSIONS IN ENCLOSED SPACES
Environmental Engineering and Management Journal › Vol. 18 › Nr. 4 Explosion-type accidents can cause significant human losses and material damages; therefore, special attention has to be granted to
explosion risk assessments and to the development of appropriate explosion-protection measures. Such measures of protection aim
to reduce the explosion risk to acceptable levels, in compliance with regulations and standards in force, so as to provide the proper
safety level for humans as well as to prevent damage to the surrounding goods and environment. The flas... Autori: Marin Silviu Nan ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27961
DETERMINATION OF COAL MICROELEMENTS BY INSTRUMENTAL ANALYSIS
Environmental Engineering and Management Journal › Vol. 18 › Nr. 4 In the mineral matter of coal there are microelements chemically bounded to organic matter or mineral impurities in various
combinations that catalyzes the evolution / involution of a spontaneous combustion phenomenon as an accelerator in the oxidation
reaction or which slows down these processes.
Specialised literature analyzes the phenomenon of coal self-heating based on several theories of which we exemplify the theory of
coal oxidation, the theory of pyrite and the theory of the microele... Autori: Cristian Tomescu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27966
BIOMASS EXPLOITATION FOR ENERGY SUPPLY AND QUALITY COMPOST PRODUCTION. AN EXEMPLARY CASE OF CIRCULAR ECONOMY IN THE NORTH EAST OF ITALY
Environmental Engineering and Management Journal › Vol. 18 › Nr. 10 The goal 12 of the 2030 Agenda for Sustainable Development takes into consideration the responsible consumption and production in the perspective of circular economy. The agri-food sector is more actively involved in these initiatives, because it offers the possibility to exploit waste and by-products, by adopting suitable biotechnologies. Such processes can be carried out either under aerobic conditions, for the production of compost, or anaerobically, for the production of biogas. In this work...

USE OF BENTHIC MACROINVERTEBRATES IN THE DIAGNOSIS OF BEGA RIVER WATER QUALITY AND SELF-PURIFICATION PROCESS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 3 The anthropic impact, having various forms, negatively changes the parameters of water quality and disturbs the living environment of benthic macroinvertebrates. The purpose of the present study is to present how the main sources of pollution influence the way of life of the benthic macroinvertebrates community. 20 quantitative benthic samples were collected from different benthic areas of the Bega River water during from June 2014 to February 2017. In addition to identify all the changes that o... Autori: Adina Horablaga ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28178
A SURVEY OF FACTORS INFLUENCING SPREADSHEET RISK AWARENESS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 5 Motivated both by reports on devastating financial and reputation-related consequences of spreadsheet errors and the results of previous studies suggesting a significant lack of users’ awareness of spreadsheet risks, this paper provides insight into factors that
influence users’ perception of risks associated with creating and using spreadsheets. The survey was conducted on a sample of 161 spreadsheet users, whose attitudes were analyzed in accordance with 17 attributes. Statistical...

INSTRUMENT FOR ASSESSING THE SUSTAINABLE INNOVATION CAPACITY OF PROFESSIONALS IN CONSTRUCTION
Environmental Engineering and Management Journal › Vol. 19 › Nr. 6 Architects and engineers play an important role in the choice of innovative and environmentally sustainable materials and techniques. To define these materials and techniques, they mobilize competencies acquired throughout their lives. To learn the profile of the environmentally innovative architect and engineer in Brazil, we created a self-assessment instrument that allows us to
identify essential characteristics in practice, namely, which competencies are mobilized when they choose an environ... Autori: Elaine Resende ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28223

HOW TO DEAL WITH ORGANIC MUNICIPAL SOLID WASTE OVER-SIEVE FRACTION
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 The steady increase in separate waste collection has highlighted the urgent need to adequately deal not only with urban waste (differentiated and undifferentiated) but also with special waste produced by separate waste collection and recycling processes.
Source collected municipal solid waste produces different waste streams. One of this is the organic fraction of municipal solid waste (OFMSW). This fraction is central for circular economy, since it can be further transformed in order to recove... Autori: Ivana Moscato ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28302 |
