Abstract. The paper focuses on air quality monitoring campaigns in the city of Timisoara, in Romania. The measurements occurred during representative episodes, in the Northern and Southern part of the city, and the results were concluded in graphs and figures, raising special concern about the pollution with particles. The applied methods were standard, achieved by an accredited mobile laboratory (www.mediu.ro), as required by ISO 17025, and refer to the species: PM10, NO x , SO 2 , VOC, ozone, and CO. Finally proposals for improving the levels of concentrations were indicated, in accordance to the state of art and specificity of the city.

This paper will focus on analysing the air quality on a frequently congested road section in the vicinity of Timisoara, Romania. The placement of the measurement equipment will be made next to a public transport station measuring the extent of different pollutants which affect the well-being of passengers waiting in these stations. The traffic congestion is present due to the unloading from the highway, reduced capacity of only a one lane road and because of the high amount of industrial area workplaces. The results presented will be part of the PhD thesis of the main author.

The global increase of the population has generated more and more requirement of the animal-based food. In order to provide this requirement, it was necessary to increase considerably the actual numbers of animals. This has led to both numerous positive and negative effects brought both to people and animals. Creating agro-touristic farms, ensuring fresh food, creating workplaces are just a part of the factors which have beneficial effects on the human beings. Yet, a major problem, which should not be ignored and neglected, is represented by the wastes resulted from animal breeding. These superficially treated wastes can cause numerous negative effects on the whole ecosystem. The animal dejections, the water resulted from the meat processing, the animal corpses, and all represent biodegradable wastes, which might be used, by transforming their energy content into electrical and thermal energy. This can be possible, for example, by using these wastes as raw material for producing biogas. To prove their efficiency in producing the biogases there have been done thermal analysis. In this article are analysed, from a thermal point of view, 3 different samples. In the first part of the experiment were analysed the swine dejections, in the second part were analysed the poultry dejections, and the third experiment consisted in the analysis of the cow stable waste. The analysis of these samples was done with the help of the Netzsch 449 C Jupiter device. The results obtained from the analysis prove the fact that all the three raw materials can be used as raw materials in producing the biogas.

The research is focusing on analyzing the concentrations of particulate matter (PM) next to a highly congested road section, with 39,900 as a maximum number of vehicles per 24 h, in the vicinity of Timisoara, Romania. Concentrations have been measured in multiple episodes using two different measurement methods, gravimetric and dynamic light scattering, showing a disperse range of PM concentrations. Presence of metal particles in the samples have been analyzed using an electron microscope. Additionally, impact on human health is described by evaluating results for inhalable, thoracic, and alveolar sized particles.
