“…Rainwater was not an effective removal mechanism of BTEX, only 0.1% of BTEX in the atmosphere was removed by rainwater [68]. But the amount of BTEX species retained in water were significantly higher than suggested by theoretical predictions indicating that dissolution is not the major mechanism of gaseous BTEX uptake in aqueous phase [69].…”

Benzene, toluene, ethylbenzene and xylene (BTEX) are the most abundant volatile organic compounds (VOCs) in the urban atmosphere. In this paper, fates and possible sources of BTEX in general atmosphere were reviewed. A fairly comprehensive review of BTEX in atmosphere of China's coastal cities was presented. In the general environment, BTEX partitions mainly into air. Higher atmospheric concentrations of BTEX were observed in the cities of south China than in north China and in winter than in summer. The atmospheric BTEX concentrations were significantly reduced over the past two decades. Vehicle emission and coal burning were the most important sources in North China. In south China, the other sources could make remarkable contribution to atmospheric BTEX concentrations.

“…Research is being conducted in the water environment in various countries: the Netherlands (surface water and river) [22], Greece (surface water) [23], Portugal (surface water) [24], Belgium (surface water) [25], Japan (rainwater) [26,27], the USA (rainwater) [28], Austria (rainwater) [29], Serbia (rainwater) [30], Nigeria (surface water, effluent of M/IWTP) [18], Taiwan (effluent of M/IWTP, rainwater, surface water) [31,32], China (effluent of M/IWTP) [6], and South Korea (surface water, effluent of M/IWTP) [5]. The reported concentration range of VOCs in the water environment ranged from several ng/L to mg/L, and was mainly the highest in the effluent of IWTP.…”

“…The most important aspects of monitoring research are that well-managed analytical equipment, and various application methods for gas and liquid chromatography (GC and LC) are used. The method detection limit (MDL) and limit of quantitation (LOQ) differ for each compound, but are mainly between several ng/L and tens of ng/L [5,6,18,[22][23][24][25][26][27][28][29][30][31][32]. The most important method for water environment management is obtaining accurate monitoring and analysis results, and the accumulated results will be used as important data for policy decisions.…”

“…The toluene and xylenes concentrations in the HRW surface water were lower by several orders than those of not only the Netherland surface water from Rhine, Meuse, Northern Delta area, Western Scheldt rivers [22], surface waters of Greece [23], Portugal [24], Belgium [25], Taiwan [32], and Nigeria [18], but also the rainwater of Japan [26,27], USA [28], Australia [29], and Serbia [30]. This implied that wet deposition could be partially considered as a reason for the increased VOC concentrations in surface water and rainwater.…”

Volatile organic compounds (VOCs), with negative impacts on the aquatic ecosystem, are increasingly released into the environment by anthropogenic activities. Water samples were collected from five areas of the Han River Watershed (HRW) tributaries, South Korea, to detect 11 VOCs, which were classified as halogenated aliphatic hydrocarbons (HAHs) and aromatic hydrocarbons (AHs). Among the 11 VOCs, 1,1-dichloroethylene, 1,1,1-trichloroethane, and vinyl chloride were undetected. The highest concentration compounds were chloroform (0.0596 ± 0.1312 µg/L), trichloroethylene (0.0253 ± 0.0781 µg/L), and toluene (0.0054 ± 0.0139 µg/L). The mean concentration (0.0234 µg/L) and detection frequency (37.0%) of HAHs were higher than those of AHs (0.0036 µg/L, 21.0%, respectively). The Imjin Hantan River area exhibited the highest mean concentration (0.2432 µg/L) and detection frequency (22.9%), because it is located near industrial complexes, thus, highlighting their role as important VOC sources. However, the detected VOCs had lower concentrations than those permitted by the EU, WHO, USA, and South Korea drinking water guidelines. Ecological risks associated with the VOCs were estimated by risk quotient (RQ); consequently, the predicted no-effect concentration was 0.0029 mg/L, and the toluene and styrene RQ values were >1 and >0.5, respectively. The findings may facilitate policymakers in designing pollution control strategies.

Anodized TiO2 nanotube fibers using in‐headspace solid‐phase microextraction (SPME) with gas chromatography–mass spectrometry (GC–MS) have been exploited as an analytical method for volatile organic compounds such as benzene, toluene, ethylbenzene, and xylenes (BTEX) detection. The factors of anodizing time and annealing temperature for TiO2 nanotube production are studied and the adsorption factors (time, ionic strength, and temperature) and desorption factors (time and temperature) for BTEX analysis are optimized. The limit of detections (LODs) for benzene, toluene, ethylbenzene o‐xylene, and m, p‐xylene are 0.5, 0.1, 1.0, 1.0, and 2.0 μg L−1, respectively. The linear ranges for BTEX (0.5–15,000 μg L−1) and satisfactory linearity (R2 ≥ 0.9954) are obtained. This method is successfully applied in real samples with the recoveries ranging from 92% to 97%. TiO2 nanotube fiber is a promising technique for BTEX analysis.
