Special Issue Information

Dear Colleagues,

Indoor air quality has become a real concern for all environmental researchers. Indoor air in urban environments contains more toxic pollutants with poor HVAC and natural ventilation systems. In indoor environments, various toxic pollutants, e.g., VOCs and PM2.5, have adverse health effects. These health effects include lung, liver, and asthma diseases. Moreover, to overcome indoor air pollution, the increased ventilation rates do not play a vital role in air quality since outdoor air pollution is already high in urban environments. In the era of COVID-19, researchers are more focused on indoor air pollution and indoor air quality as we spend 90% of our lives in indoor environments. Keeping these scenarios in mind, this Special Issue will cover all new research and technologies that can play a vital role in combatting these issues. This will be helpful for further research and will improve human health and society. This can be helpful for future generations and stimulate new, better research in the field. The availability of this research will give those entering the field a better understanding of these topics, which may stimulate the development of future technologies.

With the above in mind, I would like to invite you to contribute to this Special Issue of Toxics.

The use of air cleaners indoors has increased with the increase in indoor activities driven by the COVID-19 outbreak. In this study, the indoor air quality was determined at the location of each patient’s respirator in a four-bed hospital ward equipped with a ventilation system and curtains, by varying the position of one air cleaner. By operating the air cleaner alone without the ventilation system, it was confirmed that it is better to place the air cleaner close to the center of the ward, regardless of whether curtains are used. It was further identified that the farther away the air cleaner is from the center, the worse the age of air could be, compared to the case of operating it in the center. Moreover, the situation where the ventilation system and air cleaner were operated simultaneously in the hospital ward was considered. It was discovered that operating the air cleaner close to the ventilation inlets in the absence of curtains helps to improve the indoor air quality. Furthermore, it was found that the age of the air is generally low near the location where the air cleaner is operated in the presence of curtains. Selecting an optimal position for the air cleaner can improve the air quality at the location of each bed in a four-bed hospital ward. Full article
