Romania is a country with relatively good opportunities to manage the transition from the dependence on fossil energy to an energy industry based on renewable energy sources (RES), supported by hydrogen as an energy carrier. In order to ensure Romania's energy security in the next decades, it will be necessary to consider a fresh approach incorporating a global long-term perspective based on the latest trends in energy systems. The present article focuses on an analysis of the potential use of salt caverns for hydrogen underground storage in Romania. Romanian industry has a long technical and geological tradition in salt exploitation and therefore is believed to have the potential to use the salt structures also in the future for gas and specifically hydrogen underground storage. This paper indicates that more analysis works needs to be undertaken in order to value this potential, based on which macroeconomic decisions then can be taken. The present work examines the structures of today's energy system in Romania and features an analysis of Romania's current potential of hydrogen underground storage as well as, reports on the potential use of this hydrogen in chemical industry, the transport sector and salt industry in Romania and highlighting issues implied by a possible introduction and use of hydrogen and fuel cell technologies. © 2014, Hydrogen Energy Publications, LLC.

The aim of this article was to evaluate and compare the levels of aldehydes and ketones in indoor air of a new office building in rooms with new and old furniture. The sampling method involved both passive cartridges and silica gel DNPH-coated tubes. Aldehydes and ketones levels were quantified using a DNPH-derivatisation method followed by liquid chromatography coupled to UV detection for 14 aldehydes and ketones. The results obtain showed that both active and passive sampling methods can be used for indoor air aldehydes and ketones assessment depending on what you intend to achieve: long-term average or short-term monitoring. Results revealed that higher concentrations of aldehydes and ketones were found in rooms with new furniture compared to rooms with relative old furniture, making new furniture a possible source of aldehydes and ketones.

Detergents industry is a competitive industry, with a large opening to innovation and economical development. Although very useful for sanitation, the big domestic and industrial detergents consumption has a significant contribution to surfactants concentrations increase in towns sewage and implicit to surface water contamination. At European level, detergents and cleaning products have a special place in legislative framework of the European Community because are manufactured in big quantity and they may affect the environment both during manufacture and using processes. In the last years surfactants biodegradability was the most significant problem. For this reason, at European level through Regulation (EC) No 2004/648 (and its next amendments), strict regulations were introduced in order to assure the environment and human health safety. After Romania adhesion to the EU, the European Regulation of detergents becomes also an applicable law at national level through Governmental Decision No 658 /2007. The present paper wants to give a special attention for the following aspects: (1) the national and international legislative framework concerning the commercial surfactants - products for human use, in order to assure their free circulation on the market; (2) the requirements of Detergents European Regulation concerning the final biodegradability of surfactants and complementary risk assessment for their potential recalcitrant metabolites on aquatic organisms; (3) the most practical and sensible methods for surfactants ecotoxicological testing.

Fine particles (smaller than 2.5 (μm) penetrate more deeply into the lungs than coarse particles (2.5-10 μm). Recent health studies indicate a link between fine particle concentrations in the outdoor air and certain health effects. Adverse health effects from breathing air with a high PM2.5 concentration include: premature death, increasedrespiratory symptoms and disease, chronic bronchitis, and decreased lung function particularly for individuals with asthma. In an effort to reduce and control the hazards associated with PM2.5, EPA (Ecological Protection Agency) issued federal standards in 1997 tobe complied on a county basis. The guidance on monitoring published by EPA emphasises placing monitors in areas impacted by fine particles that are also locations where people live, work, or play. The study covered by the present project is referred to determination over three years of the pollution level with PM2.5 particulate matter in areas with intense road traffic and assessment of this pollution on population health. This will bedone by means of specific test, in a first phase for respiratory function, ventilator functions, respectively, and in a second phase the characteristic tests for the presence of poly- and mono-nuclear hydrocarbons in particulate matter. The tests in the second phase will include the tests for dosing α1, antitripsina, 1 hydroxypyreneand S-phenylmercaptic acid on batches of exposed and control human subjects. The present paper will present the level of pollution with PM2.5 in the area of interest. This levelis based on measurement conducted according with SR EN 14907/2006 standard requirements.Also, the paper will present the dynamic of daily pollution level evolution in correlation with road traffic, both for cold and hot seasons.

This paper presents the results of an indoor air quality monitoring study conducted in an office building located on the outskirts of Bucharest, in an area characterized by low traffic and no major industrial pollution sources, during the summer of 2013, from 14thof June to 3rdof July. The aim was to determine the concentration of particulate matter dimensional fractions PM2.5 (particulate nominal diameter less than 2.5μm), PM10 (particulate nominal diameter less than 10μm), Total Suspended Particles (TSP), the PM2.5 and PM10 percent from TSP, metals and also the water-soluble anions present in the particulate matter in indoor air. The concentration of particulate matter varies widely from a minimum of 11.93μg/m3 for PM2.5 in weekend up to a maximum of 86.75μg/m3 in a working day with intense activity. The PM2.5 average concentration for the period was 42.64±28.28μg/m3; for PM10 it was determined a period average of 44.09±28.29μg/m3 and 46.44±30.41μg/m3 for TSP. The particulate matter are composed mostly of fine particles; so PM10 contains a 96% of PM2.5 and total suspended particulates are form from 91% of PM2.5. Analysis by ICP- EOS technique for the acid mineralization of the particulate matter retained on the filters lead to the identification of 15 metals: K, Ca, Fe, Al, Na, Mg, Pb, Zn, Ni, Ba, Cu, Ti, Mn, As, Cr. The metal content in the three dimensional fractions is different, indicating the probability existence of an indoor source for particulate matter with metals. Regarding the content of water-soluble anion in the three dimensional fractions, were identified following ions: NO3 -> SO4 2-> Cl -> F -> PO4 3-> NO2 -. Pearson Correlation Analysis indicated a high correlation between all the dimensional particulate fractions and also between metals and anions present in particulate matter. As so, the correlation coefficients for metals have values of R=0.96 for PM2.5/PM10; R=0.93 and R=0.88 for TSP/PM10 for PM2.5/TSP. The high correlations were maybe obtained due to the composition of the PM10 and the TSP, both consisting in PM2.5 particulates in percentage of over 90%. ©, 2014, SGEM2014. Source
