The removal and collection of dust particles from the air discharged into the atmosphere by industrial plants processing, transporting and storing dusty materials is an important objective for employers to prevent air pollution according to environmental legislation and employee safety regulations. Where the dust in question is flammable and may generate an explosive atmosphere, measures must be taken to prevent explosion and/or limit the effects of explosion. To this end, proper assessment of the risk of explosio...

This paper analyses the environmental impact produced by fish and meat canneries. The TULCO SA factory in Tulcea County is presented as a case study. Located on the Danube banks, it has a guaranteed and permanent source of fish and meat; fish from the Danube and fish farmers and pork and beef meat from a nearby breeding complex. Some specific analyzes of the impact on wastewater, air, and soils are illustrated. Impact on wastewater is detailed for the production of canned fish and pork and cattle meat, at differen...

The continuous development of human society from a technical-economic point of view is closely related to the increase in energy consumption. However, this implies the rapid depletion of existing fossil fuels and an accelerated increase in global pollution. At the moment, to counteract these impediments, one of the most important sources that can be used for the purpose of energy production, without having a negative impact on the environment, is hydrogen. Due to the fact that, when mixed with air, hydrogen can ge...

A significant seismic sequence started on 13 Feb. 2023 at 14:58 GMT with a mainshock of 5.2 ML located at 17 km depth and at 14 km distance NW from Targu Jiu city. The first shock was followed by 16 aftershocks with magnitudes between 2.1 and 3.4 after which a second mainshock of magnitude 5.7 was triggered next day, 14 Feb., at 13:16 GMT. The largest acceleration at the second shock (105.25 cm/s2) was recorded at Gura Zlata station as well. The seismic events hypocenters are established by several methods. First ...
