Abstract: Food antioxidants are defined as compounds that protected the foods against to the degradations provoked by oxidations. Usually, in the food industry, are used synthetic antioxidants do to the great antioxidations capacity. Unfortunately, these compounds are dangerous for the costumer. The natural antioxidants such as tocopherols and extract reached in phenolic compounds and flavonoids are recommended to use. These compounds have near antioxidative protections, an antimutagenic and  antitumorale action being involved in  the cell oxidative process.
Key words: antioxidants, ecology, protection, human health

Abstract: Noise has historically been the main environmental issue for people living close to airports. Nowadays, although the aircrafts are more and more silent and the project designed to create new engineering technologies are more and more daring, the problem of noise caused by aircrafts is far from being solved. The aircraft noise management imposed a careful evaluation of the different solutions specific to each airport, and they need to be applied without altering the relevant legal liabilities, the existing agreements, the current legislation and the established policies.
Key words: aircraft noise, new technologies, management, impact

Abstract: Directive 2002/49/EC of the European Parliament and of the Council constitutes the main normative document at European level relating to the assessment and management of environmental noise. This directive was transposed to the Romanian legislation by HG 321/14.04.2005 whose objective was to define the unitary approach at the national level in order to avoid, prevent or mitigate the damaging effects, including the discomfort, due to the exposure to the environmental noise. With this transposal, there were initiated also the actions regarding the noise cartography and elaboration of the action plans. The deadlines imposed by the European Union were tried to be respected but this was not succeeded at the level of our country, and the terms were delayed. The Project PHARE/2004/016-772.03.03/02.02 (Strengthening institutional capacities for implementing and enforcing noise Directives) has represented the main tool of financial and technical assistance for the clarification of these issues in Romania. The training sessions of this project were welcomed for the personnel involved in this type of actions, achieving the intended purpose entirely.
Key words: European legislation, environmental noise, cartography

Abstract: The cities that benefit from a long lasting history are preserving more or less the features of their initial structure thus including the traits of their historical evolution. The shifting time and people's requirements are changing gradually the face of the city but all these modifications preserve the same spirit of the city along the centuries through the components of the whole: the streets, the squares, the water courses. Bistrita city stands for the illustration of this fact. It has maintained the appearance of an old medieval city and if one like to work on the rehabilitation on this area, the city would became a case after an attentive analysis.
        Excepting the damages caused by human acts (indifference, ignorance, or mean interests), there are numerous environmental elements that are seriously affecting the state of the old buildings. Nowadays, along the art historians, archeologists, the historians, the architects and the town planning experts' contribution, the environmental sciences play an outstanding role in approaching the problems of the old building areas.
Key words: environmental sciences, historical evolution, Bistriţa city

Abstract: Seems all times, man was looked for confort in Nature. He  surrounded his territory with green areas empirically ensuring an “ecological territory” providing relief. Therefore for some of its properties he proceeded in the same manner. Wither there were green curtains, hedges or what are we are calling now “ecological corridors” these structures prove their direct benefits assisting in a better understanding of Nature. Their significance is even more relevant in economy and ecology.
Key words: ecology, corridor, economy, environment

Abstract: From the vertebrates, the freshwater fish species have the largest share within the introductions of alien species. The reasons for introductions are diverse: food sources, ornamental, biological control, accident etc. Negative effects upon the environment are much numerous than the positive or indifferent ones. Negative effects manifest through degradation of host environment, competition, predation, appearance of stunt populations, genetic degradation of local species, introduction of parasites, socio-economical effects.
Key words: alien fish species, introduction, impact, environment, negative effects, native species

Abstract: This article represents an analysis of the local conditions which characterizes a production unit, emphasizing the obtained knowledge during this study. The specific features of intervention through cultural operations in mountanious beech forests are to be elaborated differently, in order to respect the characteristics of the research station and the nature and state of the brushwood. The goal is to get as qualitative brushwood as possible respecting the environmental specific characters and the silvicolous potential of the research station and its functions.

Abstract: The monitoring of the environmental radioactivity using thermoluminiscence dosimetry. Environmental monitoring of the radiation background aims through sampling or by the use of direct detection equipment to quantify the levels of radioactive substances and ionising radiation resulting form natural sources as well as from human activities. The paper presents the implementation of thermoluminescent (TL) methods for environmental dosimetric monitoring of the terrestrial gamma radiation background. The dosimetric system consists of a  Risø TL/OSL DA-20 reader and the highly sensitive LiF: Mg, Cu, P thermoluminescent detectors (commercially known as MCP-N). The lower limit detection (LLD) for this system is 5,5 μSv, a value which indicates that this system can be successfully used for environmental purposes. Measurements have been conducted in Cluj-Napoca as well as in Ştei area at Băiţa Plai, near to the former “Avram Iancu” uranium mine, which is a radon-prone area and assumed to have a high natural gamma radiation background. For Cluj-Napoca the natural gamma radiation dose rate found was 0,113 ± 0,016 μGyh-1 for outdoor exposure. Due to the influence of building materials radioactivity, values of 0,186±0,002 μGyh-1 for indoor exposure have been measured. In Băiţa Plai for outdoor exposure slightly elevated values of 0,185±0,042 μGyh-1 have been determined. Regarding the environmental gamma background, the values obtained are not believed to pose a direct threat to human health in the region. Our results confirm that thermoluminescence methods are very sensitive and can be applied with success for the implementation of environmental radiomonitoring networks.
Key words: environmental monitoring, terrestrial gamma radiation, thermoluminescence dosimetry, TLD, LiF: Mg, Cu, P

One of the most important functions of an automated system is to provide information about the process status. The acquisition, manipulating and monitoring of process data as an important component of these function, is not limited only to a passive state, but involves also, some intervention of personnel that supervises the process. In case we are speaking about a wide-spread area system, the efficient data monitoring can only be possible if hierarchical and distributed systems are used.

In the last couple of years, the quality of urban and periurban environment has suffered changes, being constantly influenced by a series of factors like: increasingly heavier traffic, sound pollution, certain activities that have an impact on the atmosphere. Road transport contributes to photochemical smog, acid rain, as well as accentuates the greenhouse effect (global warming). In this context, the present paper represents a part of the results obtained following a documentary and experimental study undergone in interior and periurban areas of Bucharest municipality, regarding tropospheric response times to increasingly anthropic pressure caused by vehicle transport activities, by correlating measurements results of nitrous oxides (NOx) and carbon monoxide (CO) emissions with those of simultaneous traffic monitoring. A representative case study is presented for downtown Bucharest. Also, an analysis is presented regarding meteorological parameters variation (annual average temperature and total rainfall) for downtown and periurban areas in Bucharest metropolis. The obtained results have highlighted the fact that road traffic is the main source of pollution in Bucharest and it has an important contribution to increasing climate change.
