Special Issue Information

Dear Colleagues,

This Special Issue is a follow-up of a previous Special Issue entitled "Volatile Organic Compounds (VOCs) Emissions: Monitoring and Assessment" (https://www.mdpi.com/journal/atmosphere/special_issues/VOCs_emission_monitoring_assessment) published in Atmosphere in 2023. The aim of this Special Issue is to gather papers focusing on recent advancements in the field of volatile organic compounds (VOCs) measurements, modeling, and their impact on air quality, climate, and atmospheric chemistry. VOCs play an important role in tropospheric ozone (O3) and secondary organic aerosol (SOA) formation. Tropospheric O3 can be harmful as it has an impact on air quality due to its ability to form photochemical smog and has a direct health impact as a pulmonary irritant. In addition to this, O3 enters leaves through plant stomata during normal gas exchange in the daylight hours and impairs plant metabolism and damages crops. On the other hand, SOA has a direct impact on the climate through the radiative forcing of the atmosphere and contributes to cloud condensation nuclei (CCN) formation. Therefore, it is extremely important to quantify VOCs in different atmospheric environments and from various emission sources. Monitoring and assessment of VOCs is, therefore, becoming exceedingly important for air pollution mitigation strategies.

Topics of interest for this Special Issue include but are not limited to:

  • Atmospheric chemistry of volatile organic compounds (VOCs)
  • Analytical techniques for atmospheric measurements
  • Laboratory and field experiments
  • Eddy covariance flux measurements
  • Biosphere–atmosphere interactions
  • Atmospheric models and satellite remote
  • Health impact of VOCs

Dimethyl sulfides are ubiquitous odorous substances in eutrophic freshwater bodies. In this study, a simple headspace solid-phase microextraction-gas chromatography-flame photometric detection method was developed to detect three representative algal-derived dimethyl sulfides in freshwater lake water samples: dimethyl monosulfide (DMS), dimethyl disulfide (DMDS), and dimethyl trisulfide (DMTS). The effects of extraction fiber, temperature, pH, ionic strength, and sample volume were investigated orthogonally, and the optimized method was applied to analyze surface water samples from Lake Ulansuhai in Inner Mongolia, China. Optimal extraction was obtained with a 50/30 µm DVB/CAR/PDMS extraction fiber, 20% ion concentration, 87 min extraction time, and 50 °C extraction temperature. The correlation coefficients of the standardized working curves for DMS, DMDS, and DMTS were 0.9967, 0.9907, and 0.9994, respectively, indicating good linear relationships. Limits of detection were in the nanogram range, and the recoveries of the spiked standards for DMS, DMDS, and DMTS were 97.22~99.07%, 93.39~99.34%, and 91.17~99.25%, with relative standard deviations of 5.18~5.94%, 3.08~6.25%, and 2.56~5.47%, respectively. This method is stable and reliable, and can be used for the determination of volatile sulfides in freshwater lake water. Full article

Occupational health risk assessments of exposure to VOCs still need to be extensively studied to improve the safety standards in the industry. Based on the monitoring of organic pollutants at various workstations in a truck tire factory in Jiangsu Province, both semi-quantitative and quantitative health risk assessment methods were employed to assess health risk levels. The findings indicated that VOCs were categorized into five classes, which included alkanes, aromatics, halocarbons, carbon disulfide, and oxygenated volatile organic compounds (OVOCs). The highest concentration of total volatile organic compounds (TVOCs) was found in shaping workshop; alkanes were the most abundant class (74.2%), followed by aromatics (24.02%) and OVOCs (1.96%). Although the results of the semi-quantitative risk assessment showed that most of the organic compounds had low R values, various kinds of VOCs were detected; particularly, many harmful organic compounds (such as toluene, ethyl benzene) were detected in all the sampling sites. The quantitative risk in the calendering and vulcanizing workshop exceeded the acceptable level; both the carcinogenic risk of ethylbenzene in the tire-strip storage room, and trichloroethylene and perchloroethylene in the calendering workshop were unacceptable. Thus, the calendering and vulcanizing processes in rubber tire manufacturing should be priority-controlled processes. Full article

In this study, a total volatile organic compound (TVOC) monitoring system was developed and employed for the continuous and real-time monitoring of TVOCs. Gas chromatography (GC) coupled with thermal desorption (TD) and a commercially available portable VOC detector were simultaneously applied to verify the performance of the developed system. Since the developed system was applicable with and without a pump, the effect of the pump on the monitoring performance was also investigated. Overall, the reliable accuracy and precision of the developed TVOC monitoring system were verified in the TVOC concentration of 50~5000 ppbv. Based on the simultaneous analysis with TD-GC, the TVOC monitoring system showed nearly identical performance to the TD-GC system regardless of the presence of the pump. When compared to the commercially available and portable VOC detector equipped with an internal pump, the maximum delayed response of the TVOC monitoring system was 15 min. In the VOC transport in soil, the breakthrough curve was successfully obtained compared to the case with the TD-GC system. Considering the measurement frequency of the TD-GC system, the TVOC monitoring system as a passive monitoring device can be effectively applied to the subsurface area with the TVOC concentration at or above 50 ppbv.
