MEASURES AND TECHNOLOGIES FOR REDUCING THE IMPACT OF MICROPLASTICS IN SURFACE WATERS

(STEF92 Technology, 2026, Angelica Nicoleta Gaman, Lorand Toth, Marius Kovacs, Sorin Simion, Izabella Kovacs)

Show more

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 ...

VARIATION OF VOLATILE ORGANIC COMPOUND CONCENTRATIONS EMISSION IN THE ATMOSPHERE CORRELATED WITH TECHNOLOGICAL OPERATIONS AT THE PAINTING OPERATION

(STEF92 Technology, 2024-11-15, Marius-Emilian Kovacs, Angelica Nicoleta Găman, Lorand Toth, Izabella Kovacs, Alin Irimia)

Following the vehicle painting process, residual gases containing volatile organic compounds (VOCs) are released into the atmosphere through exhaust pipes. Entrepreneurs are legally obliged to report to the Environmental Protection Agency, which, in turn, reports to the European Union to reduce greenhouse gas emissions and achieve climate neutrality by 2050. The current paper investigates the temporal variation of VOC concentrations correlated with technological processes carried out in vehicle painting shops. Thr...

IDENTIFICATION OF VOLATILE ORGANIC COMPOUNDS GROUPS IN THE AMBIENT AIR OF THE JIU VALLEY THROUGH MODERN INVESTIGATION METHODS

(STEF92 Technology, 2023-10-01, Lorand Toth, Angelica-Nicoleta Găman, Cristian Nicolescu, Cosmin Ilie)

One of the important environmental protection problems in Romania is air pollution, which is an extremely complex phenomenon. Industrialized urban settlements are susceptible to the phenomenon of pollution given the presence of various types of polluting species. The area of interest, where the study was carried out (Jiu Valley), is a mountainous region located in the southwestern part of Romania, known for its mineral resources and for the mining industry that dominated the region for several decades. Currently, ...

MONITORING THE QUALITY OF GROUNDWATER SAMPLES BEFORE AND AFTER RETROFITTING A CHROME-PLATING PLANT THAT CARRIED OUT THE TRANSITION FROM CR6+ TO CR3+

(STEF92 Technology, 2023-10-01, Marius Kovacs, Simion Sorin, Lorand Toth, Andrei Gireadă)

Since ancient times, chromium oxide was used 2000 years ago by the Chinese to cover the tips of weapons and later, as late as 1988, hexavalent chromium was discovered to be dangerous to humans. Currently, many companies carry out chrome plating of plastic parts, which consists in creating a superficial layer of diffusion, of an iron-chromium alloy with up to 10 - 20% chromium. Coating by electrolytic deposition is the most widely used method for creating protective layers for plastic materials and consists in elec...

ASSESSMENT AND PROGNOSIS OF ATMOSPHERIC POLLUTION CAUSED BY HOUSEHOLD WASTE LANDFILLS

(STEF92 Technology, 2020-09-20, Angelica Nicoleta Calamar, George Artur Găman, Lorand Toth, Simion Sorin, Izabella Kovacs)

Show more

At present, the issue of waste management is becoming more acute because of increased quantity and diversity of waste, as well as because of its more and more pronounced negative impact on the environment. The current paper showcases a study carried out at a compliant household waste landfill where the following were monitored: quality of air containing wind driven suspensions, gases coming from the warehouse surface or from trapping and burning methane resulted from landfill?s cells as well as odorants released i...

VALIDATION AND DETERMINATION OF ACCIDENTAL GAS EMISSIONS BY ADVANCED GAS SCANNING METHOD IN THE INFRARED FIELD

(STEF92 Technology, 2019-06-20, Lorand Toth)

Show more

Air pollution is a local, Pan-European and hemisphere problem. Air pollutants emitted from an industrial site can be transported into the atmosphere, contributing to low air quality in other areas. In Europe, the industrial emissions of many atmospheric pollutants have fallen substantially in recent decades, leading to an improvement in air quality in the region, but accidental emissions due to industrial or other damage can adversely affect air quality. A less controllable aspect is the alteration of the physical...

BIOACCUMULATION OF HEAVY METALS IN AREAS ADJACENT TO JIU RIVER

(STEF92 Technology, 2018-06-20, Lorand Toth)

Show more

Bioavailable heavy metals have been extensively studied in recent years because of their toxicity to natural ecosystems. Even though there is a large number of studies, relatively little is known about the biologically available metal fraction. The current study analyses seasonal concentrations of heavy metals associated with reactive fractions (solvable in HCl) in the soil of three areas on West Jiu river. Concentrations of heavy metals identified in indigenous ichthyofauna (Salmo trutta fario) collected from eac...
