“…However, they are mainly emitted to air from anthropogenic sources [27]. Their presence in ecosystem is related to fossil fuels extraction and processing [28,29]. Furthermore, combustion of gasoline and diesel fuels in motor vehicle transport is the largest contributor to emissions to atmospheric air [30][31][32].…”

Hydrocarbons from BTEX group are dangerous pollutants that can cause a threat to environment and human health. In many cases, their presence in an ecosystem is the result of accidents and petroleum products spills. For this reason, novel, more efficient sorbents are needed for immobilization of such pollutants. This paper presents an experimental study of recycled tires polymer fibers (RTPF) used as a low-cost sorbent for BTEX compounds in soils treated with cement. RTPF are a type of waste that contains polymer fibers with high content of rubber particles. The high porosity and large specific surface area of rubber result in possibility of use of RTPF as a removal material. Effectiveness of the application of RTPF as a BTEX removal material was evaluated on a basis of concentrations values above the surface of reacting mixture (at 25 ± 3 °C). It was found that RTPF addition increased BTEX immobilization efficacy, compared to the use of Portland cement alone. The maximum percentage reduction in BTEX compounds concentration was 33% for toluene. Lower level of removal was observed for ethylbenzene (21%), and substantially, small efficacy was noted for xylenes (8%) and benzene (7%). Additionally, in order to evaluate mechanical properties of soil-cement composites, analysis of their compressive strength after 28 days of maturation was performed. Tests showed a decrease in the compressive strength of soil-cement monoliths containing RTPF.

“…During summer, wind speed values were higher than during autumn, indicating that the contribution of regional sources could be important in this period. Some studies have also reported seasonal differences between graph scores and factor loadings [60,63]; these differences have been attributable to the influence of meteorological parameters on pollutant concentrations (precipitation, relative humidity, temperature, solar radiation, wind speed, and wind direction).…”

Levels of BTEX (benzene, toluene, ethylbenzene, and p-xylene) were determined in ambient air of an urban site located at the center of Mexico (Leon City in Guanajuato State) during two climatic seasons of 2018 (summer and autumn). Ethylbenzene (11.86 µg m−3) and toluene (11.85 µg m−3) showed the highest median concentrations during the study period. BTEX concentrations did not show a diurnal pattern but a seasonal trend was observed for benzene and toluene at a significant level of α = 0.05. Bi-variate and multivariate analysis showed significant positive correlations (at α = 0.05) among BTEX (excepting benzene), indicating common sources for toluene, ethylbenzene, and p-xylene and a different origin for benzene. A meteorological study was also conducted in order to determine the origin of air masses that could influence the BTEX concentrations in the study site. Finally, it was found that all BTEX species presented hazard quotient values (HQs) <1, indicating that there is no risk of non-cancer during the studied period. Lifetime cancer risk due to benzene exposure for the adult and child populations studied were estimated to be 7 in 1,000,000 and 1 in 100,000, respectively.

“…The VOCs released from the petroleum industry include the aliphatic and aromatic hydrocarbons, the most relevant aromatic hydrocarbons are BTEX—(benzene, toluene, ethylbenzene and xylene) 2 . Regarding the exposure, short-term exposure to VOCs may cause several discomforts and morbidity, such as dizziness, fatigue, nausea and depression, while long-term exposure may even result in mutations and different types of cancer 8 . Some of the chemicals emitted from the oil refineries are known or suspected as cancer-causing agents, and on the other hand, are also responsible for developmental and reproductive disorders 9 .…”

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 PM2.5, PM10, As, Cd, Ni, Pb, benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, CO, NO, NO2, NOx, SO2 and O3 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 SO2 and O3, were recorded during warmer periods, meanwhile increased levels, were detected during the cold period (in winter). The air pollutants’ concentration and distribution are affected by meteorological parameters, such as wind speed and direction, rainfall or even relative humidity. Therefore, the highest concentrations in the winter season were 1.25 times higher than in autumn, 1.3 times higher than the average annual value, 1.57 times higher than in spring and 1.79 times higher than in summer. Monthly variation of O3 showed lower concentration during winter (27.62 µg/m3) and higher in summer (46.42 µg/m3). Based on the statistical analysis, a significant Spearman correlation was detected between the studied air pollutants and meteorological parameters, and according to the Principal Component Analysis (PCA) and cluster analysis, some common sources were also detected.
