Special Issue Information

Dear Colleagues,

This Special Issue will report findings related to environmental and occupational exposure to volatile organic compounds (VOC) and gases. The scope of this effort is to build consensus among scientists and stakeholders regarding the state of knowledge on exposures, health effects, and measures to reduce these harmful effects among workers, consumers, and the general public, with emphases on vulnerable categories such as children, pregnant women, and those with compromised health due to chronic diseases. Volatile organic compounds (VOCs) are ubiquitously used in multiple industries and vocational sectors, as well as being present in many consumer products. Millions of employees work in occupations known to use VOC-containing products, indicating a high potential for exposure to VOC and other gases that may be capable of inducing harmful health effects. Similarly, consumers could be exposed to gases and vapors that off-gas from building materials such as carpets, paints, upholstery, or varnishes, or during recreational activities such as pottery, painting, and using candles and scent-emitting products. Health effects associated with gas and vapor exposures can range from acute effects such as headache, nausea, and respiratory discomfort to more serious chronic effects such as persistent neurological effects or, in some instances, cancer. This Special Issue is seeking articles which document environmental and occupational exposure to these chemicals and their health effects, means to measure and evaluate exposures, and methods for limiting exposures and control of exposures including personal protective equipment (PPE).

The COVID-19 pandemic drove the use of cleaning products, causing organic solvent contamination in hospitality environments. This pilot study investigated the presence and concentrations of volatile organic compounds (VOCs) in selected hotels in four different US cities with varying star ratings at the end of the pandemic period. Targeting 139 VOCs, 57 were detected across eight groups: alcohols, halocarbons, aromatics, alkanes, terpenes, carbonyls, ethers, and esters, in the indoor air. Alcohols were the most prevalent, especially in lower-rated hotels, suggesting higher use of cleaning supplies. Elevated levels of aromatics were detected in hotels rated under three stars, with a notable disparity compared to higher-rated hotels. Additionally, alkanes and terpenes such as n-tetradecane and d-limonene were consistently detected. Health risk assessment showed concentrations of all VOCs remained below their health criteria for customers. The cumulative cancer risk was 2.25 × 10−6 for hotel workers from chronic occupational exposure to eight carcinogenic VOCs, representing 1/3 of the lifetime risk from these chemicals in the ambient air. Cancer risks from individual VOCs ranged from 0.001 × 10−6 to 1.07 × 10−6, with chloroform accounting for nearly half of the cumulative risk. The findings underscore the need for careful selection and use of furnishings and cleaning supplies and for effective indoor air pollution control and management in hotel indoor environments.

Decompression sickness (DCS) with neurological disorders is the leading cause of major diving accidents treated in hyperbaric chambers. Exposure to high levels of CO2 during diving is a safety concern for occupational groups at risk of DCS. However, the effects of prior exposure to CO2 have never been evaluated. The purpose of this study was to evaluate the effect of CO2 breathing prior to a provocative dive on the occurrence of DCS in mice. Fifty mice were exposed to a maximum CO2 concentration of 70 hPa, i.e., 7% at atmospheric pressure, for one hour at atmospheric pressure. Another 50 mice breathing air under similar conditions served as controls. In the AIR group (control), 22 out of 50 mice showed post-dive symptoms compared to 44 out of 50 in the CO2 group (p < 0.001). We found that CO2 breathing is associated with a decrease in body temperature in mice and that CO2 exposure dramatically increases the incidence of DCS (p < 0.001). More unexpectedly, it appears that the lower temperature of the animals even before exposure to the accident-prone protocol leads to an unfavorable prognosis (p = 0.046). This study also suggests that the composition of the microbiota may influence thermogenesis and thus accidentology. Depending on prior exposure, some of the bacterial genera identified in this work could be perceived as beneficial or pathogenic. Full article
