Oil refineries and petrochemical facilities contribute to the pollution of environment either air, water, or soil releasing hazardous toxic air pollutants into atmosphere. These include nitrogen oxides (NOx), carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2), particulate matter (PM), affecting both human health. In range pollutants, is less monitored reported despite its importance in determining adverse effects. Background H2S concentrations were found commonly from 0.11 ppb 0.33 ppb. The urban areas can reach 1 (~1.4 g m-3) up more than 90 (~125 near sources emissions. Romania, standard for protected pollutant provides an admissible concentration, over a maximum interval 30 minutes, 15 µg/m³.

Abstract The rapid spread of the SARS‐CoV‐2 virus lead many European governments to issue stay‐at‐home orders for sake controlling its impacts on health systems. associated decrease in human activities and therefore emissions provided a unique opportunity real world laboratory atmospheric scientists. impact primary emissions, that is, , has been vastly studied but consequences secondary pollutants, organic aerosol, have reported lesser degree understanding is more limited. One reason chronic imbalance attention dedicated volatile compounds. In present study, we report evolution compounds under lockdown conditions Europe by analyzing concentrations relayed Airbase service Environmental Agency. Subsetting was performed account activity influence meteorology. Traffic or urban stations exhibited most important reduction benzene and, substantially, toluene concentrations. Xylenes, trimethylbenzenes, ethylbenzene also decreased conditions, though less when synoptic were with slow flows. Acyclic alkenes evidenced no change increased slightly, whereas n‐alkanes increased. relative importance sources investigated means diagnostic ratios (toluene ethylbenzene) shift from traffic toward biomass/biofuel/coal burning, indicating possible increase domestic use solvents.

Abstract Severe weather events, such as heat waves, floods, pollution, and health threats, are becoming more common in metropolitan places across the world. Overcrowding, poor infrastructure, fast, unsustainable urbanization some of problems that India faces, country is also susceptible to natural disasters. This research analyzes climatic variables affecting urban hazards Bangalore (also known Bengaluru) via a thorough review. Heat islands, drought were identified 156 qualifying publications using Preferred Reporting Items for Systematic Reviews Meta-Analysis (PRISMA) method. Contributing considered. City development key changing climate increasing dangers. While long-term variable distribution uneven, warming evident. The report promotes strong planning techniques, comprehensive policies, green areas, sustainable beyond short-term response programs boost resilience. study shows how climate, land use, dangers interconnected.

The article aims to analyze the pollution with Volatile Organic Compounds (VOC) emitted from biggest refinery in Romania, using daily and monthly series registered for two years sites on industrial platform, carcinogenic noncarcinogenic risks workers at plant. Since values of basic statistics (minimum, maximum, average) outliers indicate that most recorded exceed maximum admissible limits established by law, Peaks Over Threshold (POT) method was utilized model determine return levels benzene total VOC (TVOC). Given high obtained relatively short periods, indicating potential danger workers, we assessed TVOC exposure computing hazard index (HI) lifetime cancer risk (LCR). results 43.75% HI are above 1, a different categories workers. LRC indicates 93.75% all considered exposed TVOC.

Hazardous petroleum wastes are an inevitable source of environmental pollution. Leachates from these could contaminate soil and potable water sources affect human health. The management acid tars, as a byproduct refining petrochemical processes, represented one the major hazardous waste problems in Romania. Acid tars toxic have potential to cause pollution damage. need for identification, study, characterization, subsequently either treatment, valorization, or elimination is determined by fact that they also high concentrations hydrocarbons heavy metals, storage site its neighboring residential area. When contamination with occurs, sustainable remediation techniques needed restore quality healthy production state. Therefore, it necessary ensure rapid but robust characterization degree metals so appropriate can then be used treatment/remediation. first stage treating determine properties.

In the context of increased pollution from different sources and its significant negative effect on population’s health environment, article presents a comprehensive analysis data series formed by concentrations volatile organic compounds (VOCs) collected in three zones—storage areas reservoir park—of refinery complex Romania during maintenance period. Statistical analyses, including parametric nonparametric tests, were performed to assess correlation between studied group them based some common features. The clustered using raw data, features extracted after statistical analysis. results indicate that are not correlated do follow same distribution even though study zone is large. sites’ classification shown be more relevant viewpoint emissions level than provided series. Principal Component Analysis (PCA) indicates with highest contribution first two components maximum, standard deviation, autocorrelation, partial autocorrelation for Zone 1; average, minimum, 2; skewness, deviation 3. study’s novelty two-fold. First, it provides period storage tanks, which was insufficiently investigated literature. Secondly, since complete generally available large public, clustering their clear image levels sites where actions should taken reduce it. This investigation offers essential insights can serve as background developing effective air pollutant monitoring strategies mitigation measures understanding emission patterns identifying factors influence VOC tanks highly petroleum products.
