Ambient VOCs in residential areas near a large-scale petrochemical complex: Spatiotemporal variation, source apportionment and health risk

Kriging-Based Land-Use Regression Models That Use Machine Learning Algorithms to Estimate the Monthly BTEX Concentration

“…The highest BTEX concentrations in Kaohsiung were greater than those in Beijing (1.44 ppb for toluene, 0.54 ppb for benzene, 0.48 ppb for m,p-xylene, and 0.27 ppb for ethylbenzene) [ 32 ] and Tianjin (0.50 ppb for toluene, 1.22 ppb for benzene, 0.57 ppb for m,p-xylene, and 0.51 ppb for ethylbenzene) [ 33 ] in China. Kaohsiung also has higher BTEX figures than areas near the largest petrochemical industrial parks in Taiwan (2.56 ppb for toluene, 0.22 ppb for benzene, 0.14 ppb for m,p-xylene, and 0.07 ppb for ethylbenzene) [ 34 ].…”

Experimental study of volatile organic compounds catalytic combustion on Cu‐Mn catalysts with different carriers

“…Crude oil smelting, automobile spraying, fuel combustion, chemical production, solvent manufacturing, drug production, etc., are the key sources of VOCs emission, 2 in which the industry contribution accounted for more than 50%. 3 In fact, an enormous amount of unorganized VOCs emissions directly jeopardize the normal growth of fauna and flora, 4,5 as well as form the important precursors 6,7 of ozone and secondary aerosols, which could contribute secondary pollution and even lead to more serious destruction to environment and organism. Nowadays, adsorption, 8,9 combustion oxidation, [10][11][12][13][14] and biodegradation 15 all have been widely used in the treatment of VOCs treatment, and catalytic combustion is one of the most vital methods in reducing VOCs.…”

“…The source of VOCs is becoming more extensive and complex with large scale and speed of social industrialization. Crude oil smelting, automobile spraying, fuel combustion, chemical production, solvent manufacturing, drug production, etc., are the key sources of VOCs emission, 2 in which the industry contribution accounted for more than 50% 3 . In fact, an enormous amount of unorganized VOCs emissions directly jeopardize the normal growth of fauna and flora, 4,5 as well as form the important precursors 6,7 of ozone and secondary aerosols, which could contribute secondary pollution and even lead to more serious destruction to environment and organism.…”

Effective removal of aromatic pollutants via adsorption and photocatalysis of porous organic frameworks

“…Volatile organic compounds (VOCs), including air and water pollutants, are widely considered as some of the most important components of man-made pollution in modern industrial society. [1][2][3][4][5][6][7] Even though the utilization and emission of VOCs have caused great risks to the environment and human health, VOCs are still extensively employed, especially in the petroleum, chemical, medical and other industrial elds, as irreplaceable raw materials and inevitable by-products. 8 Aromatic compounds, including benzene, toluene, chlorobenzene and so on, are a series of the most commonly encountered VOCs, which are seriously toxic and carcinogenic.…”
