“…In addition, in typical indoor environments with pronounced spatial gradients of air pollutants, CO 2 and NH 3 levels can be elevated in the perihuman microenvironment beyond those represented by the assumption of a well-mixed indoor environment, leading to elevated personal exposure. − Future work exploring the effect of human gaseous emissions on personal exposure is warranted.…”

Humans are the primary sources of CO 2 and NH 3 indoors. Their emission rates may be influenced by human physiological and psychological status. This study investigated the impact of physiological and psychological engagements on the human emissions of CO 2 and NH 3 . In a climate chamber, we measured CO 2 and NH 3 emissions from participants performing physical activities (walking and running at metabolic rates of 2.5 and 5 met, respectively) and psychological stimuli (meditation and cognitive tasks). Participants' physiological responses were recorded, including the skin temperature, electrodermal activity (EDA), and heart rate, and then analyzed for their relationship with CO 2 and NH 3 emissions. The results showed that physiological engagement considerably elevated per-person CO 2 emission rates from 19.6 (seated) to 46.9 (2.5 met) and 115.4 L/h (5 met) and NH 3 emission rates from 2.7 to 5.1 and 8.3 mg/h, respectively. CO 2 emissions reduced when participants stopped running, whereas NH 3 emissions continued to increase owing to their distinct emission mechanisms. Psychological engagement did not significantly alter participants' emissions of CO 2 and NH 3 . Regression analysis revealed that CO 2 emissions were predominantly correlated with heart rate, whereas NH 3 emissions were mainly associated with skin temperature and EDA. These findings contribute to a deeper understanding of human metabolic emissions of CO 2 and NH 3 .

Air pollution has become a global health issue, affecting millions of people annually. It is essential to obtain accurate and up-to-date information on air quality levels to reduce the impact of air pollution on human health. Traditional air quality monitoring methods are limited by spatial coverage and the time required for sample collection and analysis. However, the Internet of Things (IoT), drone technology, and Geographic Information System (GIS) technology have enabled the development of real-time air quality monitoring systems that provide accurate and up-to-date information on air quality levels across large areas. The study found that gas concentration varied significantly at different heights, with the highest concentration at 3 m from the ground and the lowest at 9 m. The concentration of gases also varied by month, with the highest concentration of CO recorded in March at 45 ppm at 3 m, and the highest concentration of NH4 recorded in September at 66.7 ppm at 3 m. Kodungaiyur dump yard needs environmental monitoring due to the high levels of environmental pollution and health risks caused by unsegregated waste. In conclusion, developing real-time air quality monitoring systems using GIS technology is necessary to obtain accurate and up-to-date information on air quality levels. It is essential to monitor the Kodungaiyur dump yard and other, similar sites regularly to prevent the health risks associated with environmental pollution.
