Different individually applied commercial salts at different concentrations are generally used to precipitate contaminants in wastewater. In this study, we developed a treatment complementary to the lagoon system of a wastewater treatment plant by adding a combination of trivalent metal salts to chemically precipitate phosphate contaminants. Labora...

Air pollution has become a subject of extensive study of several disciplines and it is identified as one of the most damaging factors for the ecosystem and human health. In urban areas, particle emission can be found in suspension and therefore a portion of them is inhalable for humans, or deposited on streets and several surfaces, including lichen...

Fipronil is a highly active, broad spectrum insecticide with increasing and wide use. The degradation of fipronil was studied in Brazilian soil under oxic and anoxic conditions. Under oxic conditions, the half-life of fipronil was 16.9 days, with fipronil sulfone as the main metabolite, and no further degradation during 30 days of incubation. This ...

This research analyzes the behavior of different diatomite from Peru, and their potential use for the removal of heavy metals from contaminated effluents. Seven different diatomites were characterized by X-ray diffraction, X-ray fluorescence, scanning electron microscopy, specific surface area, and cation exchange capacity. The absolute removal and...

Trichloroethylene (TCE) was a widely used industrial solvent but is now regarded as a notorious groundwater contaminant. Both physicochemical and biological methods have been applied to remediate groundwater contaminated by TCE. For medium to low level of TCE contamination, bioremediation could be more cost-effective. However, bioremediation approa...

Ground and satellite measurements of particulate pollution play an important role in determining the particulate pollutant-Aerosol Optical Depth (AOD) relationship. The daily observed PM10 and PM2.5 concentration varied from 11–757 μg/m3 and 8–630 μg/m3 with the mean concentrations of 137 ± 119 μg/m3 and 86 ± 90 μg/m3, respectively. The long-term m...

Application of organics in soil can reduce uptake of arsenic (As) in food crops grown on soil spiked with As. However, the results may be different if the crop is grown with As-contaminated irrigation water. In this study, a modest initiative has been undertaken to assess the organo-arsenic equilibria using the fulvic and humic extracted from paddy...

The change in atmospheric pollution from a public lockdown in Greece introduced to curb the spread of the COVID-19 is examined based on ground-based and satellite observations. The results showed that in most cases, the change in atmospheric pollution is not statistically significant. It is probably an artifact of the meteorological conditions that...

In the paper, a correlation analysis is carried out between the components of the energy balance (types of energy resources, the transformation sector, and energy consuming industries) and pollutant emissions (CO2, SO2, NO2, CO, PM10, PM2.5) using the example of Ukraine. In general, 153 samples were formed and considered, characterizing the relatio...

Monitoring and forecasting of chemical and physicochemical parameters of groundwater is an important factor in quality control and water management. In order to optimize these processes, the initial purpose of this paper was to identify sources of pollution and predict spatial changes in groundwater quality. Patterns of spatial changes in groundwat...
