Environmental pollution with microplastics is a global concern, accompanied by a large body of research primarily focused on aquatic environments. Microplastic contamination has a considerable impact on both the biological diversity of aquatic ecosystems and human health. In this context, the present paper provides an overview of technologies and measures aimed at reducing the presence of microplastics in surface waters, emphasizing two complementary approaches: the removal of microplastics from transfer pathways ...

The coal mining waste dump of Petrila in the Jiu Valley, Romania, represents a significant source of environmental hazards due to spontaneous combustion of coal residues. This study investigates the generation of nitrogen oxides (NO, NO2, and NOX), carbon dioxide (CO2), and methane (CH4) from the Petrila dump, focusing on their correlation with self-heating phenomena and internal temperature variations. Field observations were conducted on the dump, recording signs of surface smoke, elevated temperatures, and othe...

The research investigates the impact of persistent organic pollutants, particularly pesticides, on the aquatic ecosystems of the Jiul de Est basin. Pesticides are introduced into water bodies via surface runoff, infiltration, and atmospheric deposition, and their bioavailability is influenced by factors such as pH, temperature, and dissolved organic matter. The research evaluates the ecotoxicological effects on key aquatic species, including Salmo trutta fario (river trout) and Squalius cephalus (common chub), by ...

In our century and especially in recent decades the noise level reached an increasing width, becoming a polluting source of the same severity as chemical pollution. Increasing power and work speed of equipments has contributed to diversifying and increasing the number of noise sources and thus increased number of people exposed. Noise generating sources in technological procedures of processing may be of continuous nature (pneumatic energy production, water transport) or intermittent (systems for transporting mine...

Jiu Valley represents one of the most important areas for coal mining in Romania, thus industrial development has generated a high level of health and safety at work issues. At work places in mining industry, the staff of the woodworking workshops is exposed to various concentrations of dust, possibly leading, in time, to occupational illnesses. Thus, wood processed in mining unitsпїЅ workshops is utilized for temporary support of coal faces, wrapping underground mining, insulation dams, ventilation doors, etc. Th...
