“…Chloroform, 1,2-dichloropropane and VC at the industrial and urban areas in Thailand were found to be at acceptable levels, according to the local standards of ambient air quality (Average standard, 57, 82 and 20 µg/m 3 , 24 h, respectively) (Sakunkoo et al, 2021). Additionally, methylene chloride, chloroform, tetrachloroethene, trichloroethene, chlorobenzene, and 2-chlorotoluene liberate from the treatment plants of wastewater to the air (Zhang et al, 2020). Trichloroethylene is one of the most common compounds found in indoor environments in China (Dai et al, 2017).…”

Volatile organic compounds (VOCs) include different organic chemicals that can be easily vaporized and transported long distances via the environment. VOCs and health effects are dependent on the type, concentrations and duration of exposure. Chlorinated volatile compounds (CVOCs) are the most toxic VOCs because of their potential to cause cancer in humans. Many CVOCs are present in significant amounts in our ecosystems, including air, water and soil, and are resistant to degrade, despite the fact that their use has recently been more carefully managed and restricted. These chlorinated compounds are highly toxic and numerous have been banned from commercial utilization because they are persistent in the environment and accumulate in biological systems. Although these chemicals have been banned for decades, they are still being measured in the environment and the food chain. This paper provides a comprehensive review of the recent applications of biotechnology and nanotechnology in CVOCs remediation in various environmental systems. It is divided into many sections; each focuses on specific subtopics, covering diverse perspectives on the principal topic. Sections presented in the paper include; occurrence of CVOCs in the environment, sources, potential human health effects, recent biotechnology and nanotechnology used for CVOCs remediation, advantages and disadvantages of each strategy of treatment and future perspectives in this aspect are also provided. Finally, this paper presents advanced technologies available, to remind CVOCs emissions with their relative merits and demerits, better understand this integrated technology, and to effectively apply them in air, soil, and groundwater remediation. Consequently, we hope that this paper will guide and inspire the application of biotechnology and nanotechnology to the remediation of CVOCs.

“…In advanced oxidation processes, ozone has strong oxidability and fast reaction speed and causes no secondary pollution to the environment. Therefore, ozone is widely used in drinking water treatment [66,67], printing and dyeing wastewater treatment [6,13,68] and coal chemical wastewater [69][70][71]. Ozone can decompose in water to produce stronger oxidizing substances than itself, such as hydroxyl radicals, which can effectively oxidize and degrade organic pollutants in water [9].…”

Ozone micro/nanobubbles with catalytic processes are widely used in the treatment of refractory organic wastewater. Micro/nanobubble technology overcomes the limitations of ozone mass transfer and ozone utilization in the application of ozone oxidation, and effectively improves the oxidation efficiency of ozone. The presence of micro/nanobubbles keeps the catalyst particles in a dynamic discrete state, which effectively increases the contact frequency between the catalyst and refractory organic matter and greatly improves the mineralization efficiency of refractory organic matter. This paper expounds on the characteristics and advantages of micro/nanobubble technology and summarizes the synergistic mechanism of microbubble nanoparticles and the mechanism of catalyst ozone micro/nanobubble systems in the treatment of refractory organics. An interaction mechanism of nanoparticles and ozone microbubbles is suggested, and the proposed theories on ozone microbubble systems are discussed with suggestions for future studies on systems of nanoparticles and ozone microbubbles.

“…VOCs can be a potential risk to the environment and human health. Exposure to high concentrations of VOCs, such as benzene and toluene which can lead to serious health risks (immune, nervous, and reproductive systems, and lead to several types of cancers) [1]. There are different sources of VOCs, however, concerns over VOCs emissions from wastewater treatment plants (WWTPs) into the environment have increased because WWTPs are considered to be one of the major sources of VOC emissions in different countries [2].…”

This study presents the results of an analysis of the most common Volatile Organic Compounds (VOCs) in wastewater samples from one of the largest wastewater treatment plants in Kuwait. Samples from four different locations (plant influent, aeration tank inlet, aeration tank, and plant effluent) were collected weekly and were analyzed for toluene, benzene, xylene, 1, 3, 5 trimethylbenzene, dichloromethane and chloroform. The results showed that all the selected VOCs were detected except benzene. The average concentrations of VOCs that entered the treatment plant were as follows: chloroform 0.22 ± 0.03 μg/mL, dichloromethane 0.18 ± 0.05 μg/mL, toluene 0.08 ± 0.01 μg/mL, O-Xylene 0.03 μg/mL, M-Xylene 0.01 μg/mL, P-Xylene 0.02 μg/ml, and 1,3,5-trimethylbenzene 0.02 μg/mL. The concentration of VOCs during the treatment processes decreased for all the selected VOCs (treatment efficiency >98%), except chloroform, which has increased. The disinfection process in the treatment plant might have generated byproducts (such as chloroform) which could have increased chloroform concentration. In conclusion, all of the analyzed VOCs in this study were lower than the maximum level of VOCs in treated wastewater.
