Examination of air pollutants and their risk for human health in urban and suburban environments for two Romanian cities: Brasov and Iasi.

To detect the spatial differences of atmospheric pollutants in urban and suburban areas is important for observing their aspects on regional air quality, climate, and human health. This study is focused on the evolution of PM, PM, NO and SO, concentrations, and meteorological parameters from 2010 to 2022, at urban and suburban area in the two Romanian city: Brasov and Iasi. The daily patterns of most pollutants in urban and suburban areas, are strongly linked to land-traffic emissions.

Temporal evolution of PM, PM, and total suspended particles (TSP) in the Ciuc basin (Transylvania) with specific microclimate condition from 2010 to 2019.

Modern societies are characterized by increased air pollution, and particulate matter (PM) is one of the most significant air pollutants and is a major environmental health problem. Therefore, long- and short-term exposure via inhalation, ingestion, and dermal absorption of particulate matter may cause series health issues, such as cardio pulmonary and lung cancer disease. Air pollutants accumulation is significantly higher in closed regions or basins characterized by strong thermal inversions, especially during the cold period such in case of the Ciuc basin.

Time series analysis of the air pollution around Ploiesti oil refining complex, one of the most polluted regions in Romania.

Refineries and petrochemical industries are known to be the principal sources of emissions for a number of air pollutants, such as Volatile Organic Compounds (VOCs), greenhouse gases and particulate matter, which negatively affect the air quality. The primary goal of this research was the time series analysis of PM, PM, As, Cd, Ni, Pb, benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, CO, NO, NO, NO, SO and O over an eleven-year period (2009-2019) and the connection between air pollution and meteorological parameters (air temperature, precipitation quantity and relative humidity). Regarding the pollution level of the major pollutants, the minimum pollution levels, except SO and O, were recorded during warmer periods, meanwhile increased levels, were detected during the cold period (in winter).

The human health risk assessment of particulate air pollution (PM and PM) in Romania.

Air pollution, especially the concentration of particulate matter (PM, PM) is a major issue and is the biggest environmental risk for early death. In the present study, we aimed to estimate the human health risk and to describe the spatial and temporal variation of particulate matter in Romania between 2009 and 2018. The average concentration of PM and PM particulate matter in the eight studied regions varied between 17.

The role of selenium and vitamin E in a Transylvanian enzootic equine recurrent rhabdomyolysis syndrome.

A severe form of recurrent exertional rhabdomyolysis occurs enzootically in a well-defined region of Transylvania, Harghita county. At the highest lying two settlements (more than 800 m above sea level), the prevalence of equine rhabdomyolysis is between 17 and 23%, while in the neighbouring villages in the valley it is less than 2%. The objective of our study was to clarify the role of selenium and vitamin E in the high prevalence of rhabdomyolysis in that region.

GIS-Based Multi-Criteria Analysis Method for Assessment of Lake Ecosystems Degradation-Case Study in Romania.

In general, the elaboration of the synthesis of water quality in Romania is based on the processing of a large volume of information coming from primary analytical data collected with a constant frequency by the organisms with a specific role in water quality monitoring. This study proposes a novel methodology for multi-criteria analysis aiming to evaluate the degradation state of lake ecosystems. The cornerstone of the newly presented methodology is a geographic information system (GIS) automated tool, involving the assessment of potential degradation sources affecting the watershed that supply the lakes with water.

Human health impact assessment and temporal distribution of trace elements in Copșa Mică- Romania.

The present study aims to analyze the temporal variations of PM and to assess the health risk indexes caused by trace elements from particulate matter (PM) via inhalation, ingestion, and dermal absorption by adults and children in Copșa Mică (Romania) during 2009-2019. The results revealed a high multi-annual mean concentration of PM and trace elements. The analyzed air pollutants showed a decreasing trend during the studied years, therefore 44.

Spatial distribution of trace elements (As, Cd, Ni, Pb) from PM aerosols and human health impact assessment in an Eastern European country, Romania.

In the present study, the concentrations of trace elements in PM were determined and analyzed at 115 monitoring stations in Romania throughout the period 2009-2018. The spatiotemporal distribution of trace element concentrations of PM, the source apportionment and health impact assessment, was carried out. The results showed a very high multi-annual mean concentration for PM and trace elements as well.

Spatial and long-term analysis of rainwater chemistry over the conterminous United States.

A comprehensive analysis of the chemical composition of precipitation was performed on rainwater samples collected between 1978 and 2017 over the conterminous US. A total of 86470 data records downloaded from the National Atmospheric Deposition Program were statistically analyzed and assessed in terms of precipitation chemistry. The ion abundance followed the Cl⁻ > Na⁺ > SO₄⁻ > Ca⁺ > H⁺ > NH₄⁺ > NO₃⁻ > Mg⁺ > HCO₃⁻ > K⁺ downward trend, showing that chloride and sodium were the most dominant among anions and cations.

Major air pollutants seasonal variation analysis and long-range transport of PM in an urban environment with specific climate condition in Transylvania (Romania).

The air quality decrease, especially in urban areas, is related to local-scale conditions and to dispersion of air pollutants (regional and long-range) as well. The main objective of this study was to decipher the seasonal variation of PM, NO, NO, NO, SO, O, and CO over a 1-year period (2017) and the possible relationships between air pollution and meteorological variables. Furthermore, trajectory cluster analysis and concentration-weighted trajectory (CWT) methods were used to assess the trajectories and the source-receptor relationship of PM in the Ciuc basin Transylvania, known as the "Cold Pole" of Romania.

From air pollution to cardiovascular diseases: the emerging role of epigenetics.

The association between air pollution and a wide-ranging spectrum of acute and chronic disorders-including cardiovascular diseases-is widely acknowledged. Exposure to airborne pollutants triggers harmful mechanisms such as oxidative stress and systemic inflammation, which lead to increased incidence of myocardial infarction, arterial hypertension, stroke, and heart failure. Sustained efforts have been made in recent years to discover how environmental exposures affect human health through epigenetic phenomena, such as DNA methylation, histone modifications and non-coding RNA-mediated gene regulation.

Adsorption of Remazol Brilliant Violet-5R Textile Dye from Aqueous Solutions by Using Eggshell Waste Biosorbent.

Based on the well-known excellent adsorbent ability of chicken eggshells, the adsorptive capacity and mechanism of Remazol Brilliant Violet-5R (RBV-5R) dye by eggshell was investigated. Exploiting the high surface-area-to-volume ratio and porous structure of this natural adsorbent, the developed procedure showed to be useful for the efficient adsorption of RBV-5R dye from contaminated water. The protocol was thoroughly optimized by investigating the effect of the dye concentration, biomass-contaminated water ratio, particle size of the adsorbent, pH and temperature, as they are key factors in the efficiency of the dye removal process.

Influence of peat fires on the rainwater chemistry in intra-mountain basins with specific atmospheric circulations (Eastern Carpathians, Romania).

A comprehensive study on the chemical composition of precipitation, the influence of peat fires and their relations with atmospheric circulation was conducted in the year of 2012, in two intra-mountain basins, the Ciuc basin (CB) and the Giurgeu basin (GB), Eastern Carpathians, Romania. Atmospheric circulation types showed the presence of a westerly anticyclonic circulation, characterized by a strong development of the Azores High to the northern Atlantic, contributing to the appearance of peat-fires.
