The EU's environmental policies and strategies have been developed since the 1970s and underline that the sustainable economic development and well-being of the European Union countries are based on their natural environment. They are aimed at national and global air quality regulations that...

The analytic paper presents the important aspects and relations for reporting the benzene pollutant emissions and some carcinogenic effects. In the present work are outlined some aspects of a particular molecular mixture between 6 atoms of carbon and 6 atoms of hydrogen, namely the benzene and its...

The issue of environmental pollution is regulated at European level by Directive 2008/50/EC on ambient air quality and cleaner air for Europe and nationally by Law 104/2011 on ambient air quality. These regulations are designed to protect human health and the environment as a whole, by bringing...

Biodiesel is an alternative fuel which can be used in place of diesel in compression ignition engines either in pure form or by blending it with diesel fuel. Biodiesel is a renewable fuel that is produced from vegetable oils and fat tissues. One of advantage of biodiesel is its less pollution in...

The presence of pollutants in water can be traced by colour, smell, temperature. The existence of a communication between rivers and the outside environment makes possible for pollutants to enter the water. Natural pollution of the rivers appears due to their interactions with the atmosphere, when...

The research reflected in this study aimed to determine the ecological performance of the compression ignition engine (4DC (110X125)) powered by diesel oil, rapeseed biodiesel (B 100) and diesel oil-biodiesel mixture (B20 (diesel oil 80% + biodiesel 20%), B50 (diesel oil 50% + biodiesel 50%)),...

The statistical research paper shows the important aspects, methods and instruments for reporting and analyzes the CO₂ emissions and food related to health effects. In the present work there are studied few aspects of a particular green-house gas emissions, namely the carbon-dioxide and its...

The site of chemical wastes storage Poșta Rît from Turda city is a former wastes baluster. Here there is an historical pollution process due to uncontrolled depositing of various wastes resulted from former Chemical Plant from Turda. The main pollutant which persists here is the pesticide HCH. The...

The present scientific paper synthesizes an applied work on the engineering task of piston-ring displacement modelling and simulation in the case of an internal combustion engine for agricultural application. Piston-rings configuration and displacement, as well as their particular role in the whole ...

Climate changes is the change in climate attributed directly or indirectly to human activities affecting global atmospheric composition and added to natural variability of observed climate during a comparable period. With the early industrialization human activities have led in atmosphere to an...
